>>You're talking about usenet.
>>a flurry of pulsing lights which are interpretable by me as the words of your petty rant.
I wasn't replying to a post on usenet. The person I was replying to didn't make their post on usenet. I was replying to a post made in this thread on this board of this chan. This chan is not usenet.

You never responded to any of the substantive claims made against what you were saying. The most basic being; how can you claim science has no use if you're using it to make that claim? You responded with progressively more childish arguments, so you got the same back in kind. Notice how merely using the word 'triggered' got you to ignore two whole paragraphs of material you could have had a discourse with? So this is more indication to me of hypocrisy; you claim to want to debate, but really you want to make unjustified claims and not back them up and get incensed over the tone of the discussion (which you brought down.) Which is fine -- but people will call you out on it.
>>go work your social manipulation techniques
If, as you claim, my objective is to get you so riled up I don't even have to bother disputing your (unpresented) arguments then that seems to be exactly what has happened, so it would seem I'm succeeding? My actual objective is to have a meaningful discussion and hopefully elevate your understanding and I'm failing at that, but as I care very little when someone is so vitriolic out the gate, it doesn't bother me much. However you can't have it both ways; either you admit that I am actually trying to have a debate and you're deflecting that, which is why I'm bad at manipulation, or I'm good at manipulation, which is why you're incapable of defending your claim.

>> 2+2 will never equal five
Indeed. But what you're saying is 2 I'm saying is 3, and we can proceed no further until we examine evidence as to whether it is actually 2 or 3.

It is. The first snapshot on Wayback Machine from 2018 shows that the "journal"'s about page links to cosmology.com, aka the well-known sham Journal of Cosmology, and the two publications appear to share the exact same staff.

Here are a few of them, if you're curious. Wickramasinghe of course had a prolific scientific career in astrochemistry before going off the deep end and claiming, among other things, that the red rain of Kerala was alien bacteria trying to invade the Earth and that all the numerous well-preserved Archaeopteryx dino-bird fossils are hoaxes. Deepak needs no introduction. And the third guy, the executive editor-in-chief, is also the lead author of the Mars paper!

I was listening to an episode of "The last podcast on the left". They were talking about the WOW signal.
If you aren't familiar LPOTL is a bit like coast to coast AM but hosted by some guys who are actual skeptics and fun. So some of this may not be accurate but its fun to think about.

They were saying that if it was anything intelligent broadcasting that we only got a snippit of the message because at the time scans of the sky were limited to rotation of the earth (they used the number 72 seconds but i have a feeling that was an approximation), then later when the location of the signals point of origin was found it was a region of space with no stars or really any thing at all.

The hosts speculated also if it was intelligent due it being in that really empty place in space and then we never saw it there again, it's likely the sender were simply in transit some where and we picked up some distant comunicqae of a "passing ship i nthe night".

although its like 900% more likley to be random noise or a misinterpreted signal from earth/[%]

lets say you were somewhat nearby a rapidly rotating neutron star such that the star's diameter was a significant portion of the distance from the star. Would the star's effective center of gravity be offset towards the approaching limb because of the relative velocities and redshifts of the approaching side versus the retreating one?
If its real, how significant would the effect be? Does the effect imply that the gravity well isn't symmetrical?

Why did all of the material in those two spiral arms lose all of their angular momentum and head for the core at the same time? I bet those two hard right turns those arms tax are separated by 15-20kpc. Since so many galaxies do this, whatever is happening to this one must be pretty common.
Also check out all those galaxies buried in the background, there must be some kinda awesome galaxy cluster back there.

heres an image i found which completely explains galactic rotation curves in terms of an expanding rather than a static universe. given that the hubble constant is 68 meters per second per kiloparsec and galaxy is several kpc wide, the velocity necessary to maintain a circular orbit increases substantially with radius rather than falling off without any necessary dark matter present. the imaginary shell of dark matter causing apparent negative graviton doesn't exist, the apparent negative gravitation is probably the momentum left over from the pre-decoupling era or som shit like that.

Another thread made me start thinking about this. The Fermi Paradox states (thanks, Wikipedia):

>The Sun is a young star. There are billions of stars in the galaxy that are billions of years older;
>Some of these stars probably have Earth-like planets which, if the Earth is typical, may develop intelligent life;
>Presumably, some of these civilizations will develop interstellar travel, a technology Earth is investigating even now, such as that used in the proposed 100 Year Starship;
>At any practical pace of interstellar travel, the galaxy can be completely colonized in a few tens of millions of years.

If that's the case, why haven't we been colonized already, or at least seen evidence of intelligent life somewhere in our galaxy?

My take: either A) Life takes a long time to develop, and somehow, improbably, we're the first planet to develop an intelligent civilization in our galaxy, or at least one of the first. We don't see anyone else because there isn't anyone else to see... yet, or we're all still too far apart.

Or b) Given the size and composition constraints of a planet able to foster and sustain life (as far as we know, "habitable zone," big enough to have an atmosphere, small enough to still be rocky, etc.) and continue long enough for said life to begin to explore the galaxy, the home planet simply runs out of resources before meaningful headway can be made. I think this is more of a slow-death kind of thing where maybe we get to do some exploration within the solar system and maybe a bit beyond for a while, but overpopulation, war, disease, famine, and whatever else causes us to realign our priorities from space exploration to merely sustaining life on our own planet. A civilization that had the foresight to know something like that was happening could theoretically, if they had the goal of galactic expansion from the start, avoid this situation, but the problem is that NO civilization has that kind of 10,000 year plan from the get-go, and they all sputter out right before they could have pulled it off. There's not a textbook on "how to succeed as a species" that gets handed out to a life form when it develops self-awareness,…

>>Kardashev IV: Energy output equivalent to the universe
>>such a civilization could not be detected, as its activities would be indistinguishable from the workings of nature (there being nothing to compare them to)
The obvious end-point of all speculations on science and technology. "God of the Gaps" chased to the edge of the cliff, Clarke's technology indistinguishable from magic. It's useful as a thought experiment, but it's not a scientific theory by definition, because it's unfalsifiable. *Any* speculation about a Type IV civilization is inherently non-scientific, for the reason given in yellowtext above. Any experiment you could possibly design to test the theory could never give a meaningful result, because any result could be manipulated by the Type IVs and you'd have no way to know. Note that saying it's not scientific doesn't mean it might not be true, but it also says we'll never know for sure that it is true, unless someday we develop a heuristic more powerful than the scientific method.

>>Aliens need FTL to reach us, once near FTL i'm assuming the hard-limits of science are also approaching an end, so finding aliens/ships/ aliens finding us (in ships),(like the ones we draw and talk about for the most part) most definitely, a meme
Naw. Just because FTL is beyond our current scientific horizon doesn't mean it's actually the end of science. People thought the discoveries of electricity and radium were signs of the end of scientific progress. The next hill to go over always obscures the most of your vision; doesn't mean it's the top of the mountain.
Which means that if "aliens" (really, might as well call them gods at this point) did create the rules of our universe and manipulate them for ends completely unknown to us (but at least somewhat within the scope of 'our benefit' thanks to anthropic tuning) then they could also create as many other 'aliens' at our level of development as they wanted to, too. They could suspend or tighten the laws of FTL in any way they wanted, and besides, it seems pretty wasteful to create a whole infinite universe just to get one planet's wo…

Relative to us, they can do whatever they like, if this is their universe. They would have constraints themselves of some kind, presumably, in their native universe, but probably on an order beyond our comprehension. If existence as such is some sort of self-generating alien simulation, that's somewhat of a more inexplicable situation. Can something really bootstrap itself into existence, or does the fact that something exist necessarily imply a pre-existing ground for existence to take place in? (This is pretty much why Type IV talk is definitely more of a /pss/, /wc/ or frankly /spooky/ thing)

lets say you were able to place a mirror in space out at such a distance that the mirror experience cosmological redshift from your perspective. If you were to shoot a laser beam of some wavelength at the mirror then the light reflecting off the mirror would be a longer wavelength than the originating laser because of the relativistic doppler effect.
what wavelength would the light be when it got back to you after bouncing off the mirror? would it be the original wavelength or would it be redshifted?
if its not the original wavelength then how was energy conserved?

I don't think there is any information lost from redshift. It's the underlying space that is expanded during redshit, not the lightwave itself.
If you are in a reference frame that negates that expansion, you get exactly the "original" wavelength.

So I think this "relativistic reference frame" telescope would theoretically work.
There are some practical considerations though:
Pointing a telescope in the direction of travel means it is exposed to all the interstellar dust.
So you maybe need a vanguard of other ships that absorb it so it doesn't wreck you instruments.
Apart from that I think we could actually calculate if it's feasible to move that fast at all, drag of the interstellar medium becomes significant once you hit a considerable fraction of c.

In star trek sci fi shows they use electromagnetic fields to control interstellar dust. Could it be simple as ionizing the telescope? Also, though it would negate some of the benefits of having a large aperture to observe large wavelengths, if the telescope was quite small it might be possible for it to exist entirely within the bowshock of a forward facing shield. Would limit its field of view, but directly forward objects might not be the ideal candidates anyway because of the blueshift thing.

>Quoting “Heaven and Earth” by Gabrielle Henriet.
“If flying had been invented at the time of Copernicus, there is no doubt that he would have soon realized that his contention regarding the rotation of the earth was wrong, on account of the relation existing between the speed of an aircraft and that of the earth’s rotation.

If the earth rotates, as it is said, at 1,000 miles an hour, and a plane flies in the same direction at only 500 miles, it is obvious that its place of destination will be farther removed every minute.

On the other hand, if flying took place in the direction opposite to that of the rotation, a distance of 1,500 miles would be covered in one hour, instead of 500, since the speed of the rotation is to be added to that of the plane.

It could also be pointed out that such a flying speed of 1,000 miles an hour, which is supposed to be that of the earth’s rotation, has recently been achieved, so that an aircraft flying at this rate in the same direction as that of the rotation could not cover any ground at all.

It would remain suspended in mid-air over the spot from which it took off, since both speeds are equal.”

While we were all out I was wondering about gravitons. If they're analogues of photons in a sense then gravitons should exist in a spectrum like photons, etc. Our ability to manipulate and understand the photon is pretty miraculous, but how would something like a prism for gravitons work? Prisms function with light because the speed of light in the medium is different than it is outside, what is there that could change the speed of a graviton or reflect it?

>I think any analogy breaks down when you strain it beyond the point where it makes sense
I agree, but stressing theory to the breaking point is what gedankenexperiment is all about. Thats one of the things I learned in school. I lot of people were convinced black holes existed well before any observations suggesting such a thing were made. They were able to estimate that these things were around based on thought experiments (gedankenexperiment) with extreme mass densities.
The case of a larger, less dense object intercepting more flux of gravitons could easily be explained away by the weakly interacting nature of the graviton. Observations of the moon during eclipse suggest that graviton shadowing doesn't happen. Somewhere or other I read that gravitons interact with matter at about the same rate as a neutrino, so they don't behave like a photon as far the graviton's force carrying concept goes.
To take an even broader view of the situation, it also seems unlikely that a person who has all of the modern distractions facing them 24/7 is likely to think up something better than some professional nerd from the 1950s who only had books and slide rules to look at, but neglecting that for the moment, its still a fascinating topic.
Given that gravity bends space and time in the way that it does, I don't even completely buy the idea that gravity is the force in question. If distances apparently increase as one travels towards a massive object then maybe the mass is emitting space.
Anyway its something interesting to think about. Kip Thorne has a thousand and one alternative cosmologies that he invented to match observations which have potential explanation outside the mainstream, one of which is that the expansion of the universe is due to the random winking into existence of a single hydrogen nuclei once every million years per cubic parsec. He doesn't believe any of his own bullshit I don't think.

You're pointing out the intellectual poverty on a meta-theoretic level of standard cosmology, and I think for some people that's so obvious as to not need statement, but most rank-and-file academics and science-literate people are still wholly convinced that LCDM has everything figured out, which is why we're stuck where we are. I think the reason you're seeing such a marked uptick in hangwringing over LCDM in the literature is precisely because the 'average' physicist has been exposed to these realities long enough to realize just how little ground they cover, and for just how long science is willing to wander into blind alleys, and are now figuring out how to communicate that to the faithful masses. Actually making a fundamental revolution in theory on the order you're suggesting (something that could recontextualize relativity) would create a shockwave in world affairs just as severe as Einstein's discovery did. So I would suggest it's not just that science has become dogmatic, or that scientists and people in general are buried under waves of distraction (which were all, incidentally, made possible by the scientific breakthroughs of the previous generation) but that the broader socio-cultural conditions aren't favorable to another drastic change. There are plenty of people who have alternative concepts, but it isn't in the zeitgeist to take them seriously, especially during the process of the breakdown of the current zeitgeist whose intellectual foundations lie in the previous wave of discovery.

So what I'm really saying is, wait 20 years. Breakthrough does not come out of comfort and distraction, it comes out of strife on the edge of oblivion. Einstein came up with relativity in a filthy trench under artillery bombardment -- and don't think that European academia's willingness to jettison the luminiferous aether in the face of relativity had nothing to do with national spirits broken by adherence to the previous centuries' failed philosophies and perspectives.

Democritus came up with the atom and Alexander of Hero came up with the steam engine thousands of years before either would become accepted and used, and not because o…

All of what your wrote about societal unwillingness to accept new discoveries rings true even if does seem so stupid. Greeks could've had steamships, but they were already satisfied with what they had? Oh well, too bad for them I guess.
The Wright brother's invention wasn't acknowledged by the general public until years after they'd been flying.

The idea of space or time being created beyond the event horizon must be a retarded alternative explanation for the apparent expansion of the universe given that it takes place beyond the event horizon, I just pulled that one of out my ass when I was wondering what happens at the bottom of a gravity well when it changes from being part of the curvature to the XYZ plane into being a hole with sides that are nearly or eventually perpendicular to the XYZ plane.

>>original article

Quick rundown of the findings, which are earth-shattering if fully true, and still quite interesting if only partially true: our galaxy is orbited by a smaller spheroidal dwarf galaxy currently visible within the constellation Sagittarius. For hundreds of millions of years, it has been orbiting in a perpendicular orbit after having been pulled into the Milky Way's gravity, having stars pulled off of it each time it passes through the galactic disk, to the point now where it is very small, faint, and nearly at the point of losing gravitational cohesion. You can see a visualization of the stream of radiation left by the galaxy astronomers used to determine its path in the pic.

Now this is where it gets interesting.

It just so happens that Sol is directly within this stream of debris. For 99.9% of our orbit around the galaxy, we wouldn't be within that stream. Also, incidentally, we are at an angle to the plane of the galaxy, which was always thought a little bit odd, since most stars planetary orbital plane is parallel to the galactic plane since during accretion their accretion disks are subject to inertial forces from the star's orbit around the galaxy.

Given the extreme odds of us just happening to be within that stream, it would seem to suggest that Sol itself is native to the dwarf, having been pulled out on the dwarf's last passage through the galactic plane.

-The period of the dwarf's orbit is around 200 million years. It is roughly 25% of the way through its orbit counting from our position in the galactic plane, which means we would have been caught by the Milky Way about 50 million years ago. The last time we passed through the plane before that, presumably still gravitationally bound to the dwarf, would have been 150 million years ago.

uneducated pleb here. would it be a good idea to strive for escaping back to the drawf galaxy assuming out system came from there? If this galaxy has higher radiation than that dwarf galaxy which supposedly we evolved from. 150 million years or so i the estimate for the transit that's with in our line of evolution isn't it? Then should we worry about an inevitable dead end in ou evolution or would we acclimate? Maybe escaping this galaxy would be a good idea esp if the fermi paradox is thrown right out the window giving the conditions here, who knows what the fuck lives here. But I'm more interested in our basic survival odds, not counting for the clockwork mass destruction events.

This some sci fi shit my dudes.

These are all unknowns, however the suggestion I made in OP was that mammals kind of are life's 'adaptation' to the current environment. But I mean, if we're going to survive in the galaxy long term, being biological organisms prone to radiation makes us vulnerable in lots of other ways too. So it's best just to fix that.
Besides, the level of tech we would need to migrate to the dwarf is way higher than the level of tech we (or any other aliens) would need to become machines, so if this galaxy is indeed fatal to organic life, most civilizations would converge on that as the optimal solution I think.

OP's post sounds like a bunch of absolute hogwash and I cannot find any other sources for it than his own link which literally discusses things like bigfoot alongside this.
>Then should we worry about an inevitable dead end in ou evolution or would we acclimate?
No because we are currently living in a man made mass extinction event already caused in part but not entirely by climate change (the rest of the mass extinction is due to numerous other factors of human activity like 7 billion hungry mouths stripping the ocean of all sea life, completely eradicating entire species by hunting them to extinction like the Wooly Mammoth, and numerous factors from our reckless massively polluting and sharply expanding urban civilization). The amount of destruction on a global scale reminds me of a bacterial sheet. The human organism became out of whack and overcolonized its own petri dish. I think the current stage in humanity is ample evidence that intelligent technological civilizations are unlikely to ever be found because in the few instances where it happened it likely destroyed itself either wiping out the civilization or outright sterilizing much of the planet, and that is assuming these societies didn't do something really stupid like knock themselves out of orbit careening into the sun, creating a massive enough singularity to swallow their planet whole before evaporating, or any number of other scenarios in which case the actual planet itself no longer exists.

But as for now, what happens in millions of years is pretty fucking irrelevant to us when we're talking about things like climate change moving us towards ecological and societal collapse within the next hundred or two hundred years.

And before you ask /tinfoil/ is currently in the middle of forum sliding and if this it's treated as a serious topic then that's like saying climate to deniers are right


I have included counter arguments so that people can reach their own conclusions, it's hard to go against the grain and try to prove a point therefore

>It certainly is interesting to see the shift of focus in space programs from official government organisations to privately-run organisations. Whether or not that's a good thing will, of course, vary with your political views, but the ultimate outcome isn't much different. After all, corporations are driven by profit, not the pursuit of knowledge or truth.
>What is surprising, however, is the new generation of people shouting "It's true, I saw it on TV!" Except this time, it's the Internet. We have already witnessed the shortfalls of this blind belief in online materials; just consider recent US elections, the political Facebook campaigns in the UK, or the many fake-news sites run from countries like Macedonia.

In the days of Newton and Hailey there weren't dogmatic schools that tried to systemize learning. People were free to experiment and come up with theories, look at Faraday, the father of electricity. He was smart even though he didn't have a degree.

Basically universities are what the Catholic Church was back then (let's grow up no alter boy jokes please) in that they are dogmatic and have a reason to protect their source of money and funding.

I mean why was the Bush administration so keen on going to mars?

I'm scared guys. This could mean life is common in the universe, which means the Great Filter is ahead of us instead of behind us.


Then again, maybe this can show us the Great Filter is already behind us but when it comes to cosmic horror, I'm a half-empty kinda guy.

Well, how could I know that's why you quoted it? You didn't make a comment about it, and its just a fact. But if you just change my post from saying, 'by cosmic rays, though', but to 'by cosmic rays, as you imply' then it comes out the same.

To be clear, however, just because organics in Titan's atmosphere aren't biological in origin, doesn't mean Titan itself doesn't support life, it just doesn't mean that it does support life. It could have subterranean earth-like biota, or support life that operates on a different biochemistry. We just don't know until we go there.

But, Europa is probably a better candidate moon to find earth-like life, for sure.

I wasn't talking about human societies. I was talking about alien societies. I explicitly meant that there is a high chance humanity wipes itself out as within a very tiny period of time we went from industrialization to almost killing a lot of the biosphere with nuclear weapons--which we still might do in the next century--as well as things like climate change. What if we created a runaway greenhouse effect? Maybe not totally Venus tier, but something like it? We have already proven of ourselves within a single generation that the jump to that kind of pre-space industrial advancement could easily kill us all. It is not inconceivable that a majority of races in the universe that did make that jump to industrialization types of societies promptly ended up killing themselves and most of the planet, just as much as it is conceivable that on many planets a type of life similar to bacteria arising promptly (in geological terms) farted out enough oxygen into the atmosphere to kill almost everyone microbial thus creating a near-human breathable atmosphere.

What I am stating is that man is a bacteria I want to see infecting other worlds but the problem is that it is quite proven how hazardous it is to make that jump towards being a more advanced technological society without dooming themselves somehow. Not to mention as I stated previously that humanity as anything but a vaguely enlightened tribe of apes has only existed for tens of thousands of years, and that the accepted span for "historical" that is to say post-agricultural man has existed for only 10-17.000 years, which is absolutely nothing in geological terms of the hundreds of millions of years of life on earth.

Ergo, you are not just plotting the spatial but also the temporal coordinates to a planet in which a) life has arisen, b) life is at the stage of abstract thinking, c) life has achieved technical progress and advancement without having killed itself in the process. While the universe and even our local stellar cluster may be vast, that is actually an incredibly small set of coordinates.

It would of course be much, much easier if you could somehow greatly expand either your spatial or temporal search.
