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.

Even in the case there will be evidence in the geological records.
A layer unusually high concentration of iron compounds and scattered refined metals everywhere. Evidence of mining on the layers below.
I can't come up with a complete list but I've seen somebody do it, perhaps I'll find that again.
In the case of "turn the entire crust into a molten fireball" of course life itself would vanish and the atmosphere would be heated so much that it would be blown away into space.
This would paradoxically make it easier to preserve evidence of our civilization since stuff can't oxidize.

This doesn't mean a large enough chuck couln't do it though. With enough kinetic energy the upper crust could evaporate too and be blown away into space.
It would have to be an extra-solar object though since we are pretty much certain nothing of that magnitude is around as far as we can see.

We've pretty thoroughly contaminated it already though. Considering that even the exterior of the space stations have microbial life on them, and how impossible it is to irradicate every spore and microbe, the red planet is likely already colonised with lichens, puffballs, and extremophile bacteria. It's going to be a long hard journey to determine if the life we find on mars had existed before our modern arrival, unless we manage to find more complex life forms than bacteria and fungi.

After meeting our god I asked about women and he sent me traveling outside to where their creational black crystal resides. I got to know them, then after some time, both collectives let me as a male, and a female from their's, to travel to the central black hole where people reside to learn and get to know everyone. The behavior from the opposite female was so vibrant I couldn't let her near me until her mind was less flippant, so I created a string between us she had to travel up before meeting me. It almost choked her assertive behavior until she understood where I was and we met up the right way.

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/[%]
Thats so wonderful and creepy at the same time.

>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.”

>>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.
-Incidentally, these numbers roughly coincide with major extinction events on earth, presumably because the gravitational disruption of passing through the galactic plane would disturb the Oort cloud and send high levels of asteroids into the inner system.
-If this is true, the Drake equation is completely bunk, since we have assumed that earth was native to the Milky Way in making our estimates about life.
-Radiation levels in the dwarf are much, much lower than in the Milky Way. If this true, that means life developed on our planet under a condition of much lower radiation than we are currently experiencing. I don't need to tell you life and radiation don't get along, so this is a startling finding about the long-term future of life on earth (and indeed in the galaxy at large) if true.
-Higher galactic radiation would increase mean solar radiation, increasing damage to DNA among other effects. This could explain the sudden rise of mammals, as their more robust homeostatic systems could perhaps better deal with the heat increase. This would also explain why all the planets in the solar system -- not just earth -- are experiencing climatic shifts in a hotter direction before you get your panties in a bunch, we're talking about a period of warming that has been going on for at least 50 million+ years. It can't be used to explain anthropogenic climate change, which is still real

-While I don't find the rebuttal wholly convincing (its argument about the plane of the solar system is misleading at best, as well as its argument about where we should find ourselves relative to the ring of debris -- at the very least, it's not the slam-dunk debunk the author tries to pretend it is) it does bring up the problem of the lower general metallicity of the dwarf galaxy's stars. However, we can't really estimate what the stellar population of the dwarf was when it first arrived, since so many stars have already been stripped off, so this doesn't tell us as much as you would think.

What are your thoughts /sagan/? Big if true, fascinating if false, or a bunch a bunk?

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.

>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.

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?

Hey there fellow egghead stoners. Would you be able to guide me through this?

So, the whole concept of dark matter and energy. I find it a little dubious, I take it this hasn't been confirmed in any way - rather, like many theories in physics has been introduced as an attempted explanation of mismatch between empirical data and theoretical predictions.

But this is just an impression I've got from the superficial knowledge of modern physics I've got, so I'd rather first understand the basis for this hypothesis better before judging it dubious.

So the way I understand it is the concept was proposed in 30s to explain the observed movement of galaxies, in particular why some stay in clusters rather than be launched off due to the acquired speed.

So it is inferred that there must be enough gravity force to keep them together instead. This begs the first question: what is the expected mass calculation based on? As in, how'd they go about measuring that?

But all right, aside from that bit I'm missing, assume the mass predictions are sound. In Newtonian mechanics - so far so good. But now if we introduce GR we allow the concept of black holes which would escape our observations. Why does that not account for 'dark matter' effect? It fits the criteria of (1) great mass (2) inability to be observed

So the way this is taken into account, I understand, that all right - there may be black holes which we cannot observe, but we still have a rough prediction on their mass which we infer from gravitational lensing - and that is way not enough to account for 'dark matter', and hence the concept remains valid.

My questions to you anons:
1) Is the line of reasoning above more or less sound
2) Any resources on the subject to recommend which would explain in bit more detail how the calculations made? (seems like internet is full of pseudoscience articles but I can't seem to easily google a decent source)
3) Could it be possible that inferring
i) mass bends spacetime
ii) spacetime is observed to be bent
iii) therefore there must be mass
is wrong, because mass may not be the only reason the spacetime is bent. That is, could it be that the 'dark matter effect' is not due to some exotic type of matter, but rather an innate (or otherwise not yet understood by our science) geometrical feature of spacetime.
Johann Encke - Mon, 01 Oct 2018 01:21:26 EST 457vC2+I No.57461 Reply
>> what is the expected mass calculation based on?
Light from main sequence stars. We look at a galaxy, look at it's luminosity to estimate the number of main sequence stars, and estimate mass from that. Almost all galaxies thus have a totally insufficient amount of normal matter to account for their mass (although we have found some galaxies without dark matter, or with hardly anything but dark matter, but this is quite rare) or rather, what their mass would have to be in order for them to maintain coherency.

>> there may be black holes which we cannot observe, but we still have a rough prediction on their mass which we infer from gravitational lensing
You would think we could do this, but in practice we can only use gravitational lensing and other gravitational effects to detect black holes in this way if there is a significant amount of parallax on the black hole (otherwise, unless we are just lucky enough to have a sufficiently bright star in line with it and us along its event horizon, we will simply miss it) for this reason we can use this method to kind of hunt randomly for black holes, we can't use it to estimate how many black holes there actually are -- we have no idea as to the answer to that question, from an empirical standpoint.
>>2) Any resources on the subject to recommend which would explain in bit more detail how the calculations made?
>>iii) therefore there must be mass
I think there are strong reasons to suspect this line of thinking might be flawed, especially since the only reason we describe dark matter as matter is simply because we can't think of anything else to describe it as. Relatively popular but unaccepted are theories that dark matter and energy represent the influence of alternate quantum realities upon our universe, or may otherwise be some sort of shadow of the m-brane. Unfortunately, a long running contender for non-DM/DE explanations, MOND, was recently disqualified due to new observations, although people are seeing if it can be saved with an update.

In short, absolutely it could be something else. DM/DE really is just a placeholder. But that begs the question: what else? We've been scratching our heads on that one for almost a hundred years, and we have uncovered startlingly little.
