I was out camping last week and brought along my telescope. It was the first time i've seen another planet with my own eyes. Seeing the rings around Saturn was fucking amazing man. I was even able to see one of it's moons. So goddamn cool. Can we have a thread dedicated to pictures we took ourselves? This one is pretty shitty, but it's the best i could do holding my phone up to the eye piece. It was still a pretty badass experience.

artificial satellites can do it. but it requires constant course corrections to pull off as any perturbations from other bodies can mess every thing up. Naturally speaking it cannot happen, or is so rare that we have not observed it naturally occurring.

But as I said if something is circular to within error then it is circular. No satelite is perfect, it has limited precision, it's orbit is only as good as the precision of the system. If you state that satellites can do circular orbits then so can natural ones. It's contradictory to state one is circular and the other is not.

There are several pulsars which have no detectable eccentricity.

What if the Big Bang didn't really happen? I know there's a lot of fanciful math that is really eloquent and beautiful regarding the subject, but the Big Bang relies on very shaky ground. Hubble noticed that the Frauenhoffer lines of light from distant cosmic objects was shifted almost always towards the red end of the spectrum. The further-seeming objects appeared to have a greater magnitude of this effect. It was deduced that this effect was solely from a Doppler effect upon light. Thus, everything seemed to be moving away from everything else... and the Theory of the Big Bang came to be. We came to find more things which seemed to support it, as well.

Problems?

Barnard Effect- for an as-yet-unexplained reason, sunspots have a detectable redshift. They are not moving away from us as stationary blemishes on the face of the sun, but the effect is the same as the cosmological one, just of a lower magnitude. This effect was discovered around the same time that the Big Bang theory was developed and was largely swept under the rug due to its embarrassing discontinuity with that theory.

Quasars- According to our understanding of the redshift, these objects are both very distant and gigantic. Yet, we observe variations in their luminosity which occur across the entire object, as well as jets suggesting superluminal velocities. Most likely they are not hypergiant-protogalactic star monsters, but are actually much closer, smaller exotic stars exhibiting an extreme version of this Barnard's effect.

The motion of spiral galaxies does not fit with the known laws of gravity. As if it were a single object, a galaxy's furthest stars rotate fast enough to keep a congruent shape compared to the innermost stars.. the exact opposite of how gravity works in the solar system. So how do we fix this? Throw in a non-detectable, non-reactive, exotic matter that takes up most of the mass in the universe, but can never be proven to definitively exist. Whatever happened to Occam's Razor?

That's just a start. Truth be told, modern cosmology is showing that it is not unlike the epicycles and phlogiston of the past. Take dark matter for example. An exciting idea in science fiction, but…

Bro, you're just making up shit. Also, you seem to be under the impression that galaxy motion is the only evidence for dark matter. This is wrong. Case in point, because of gravitational lensing, astronomers have actually mapped its distribution (pic related). Please educate yourself before attempting to "drop bombs on my worldview" again:

Pretty much everything you said is wrong.

>the Big Bang relies on very shaky ground
No. It really doesn't. We say the universe is expanding not because it is the only possible explanation for redshift but because it predicted so much. Baryonic accoustic osculation, the CMB, the acoustic peaks and the multipoles in the CMB, angular size scale tests, the Sunyaev–Zel'dovich effect the Sachs Wolfe effect, primordial abundances, reionisation... In my book it is on quote firm footing. I consider the first to be perhaps the strongest evidence.

>Barnard Effect- for an as-yet-unexplained reason
I believe you mean Evershed. The exact mechanics are not understood but there is no reason to believe it is not non-doppler effect. It is not discontinuous with the expanding universe.The evershed effect shows both positive and negative shifts and yet comic ones are allays the latter at great distance.This effect of yours explains redshift but nothing beyond that. It doesn't explain any of the features above or even why there is a Hubble law to begin with.

>Quasars- According to our understanding of the redshift, these objects are both very distant and gigantic. Yet, we observe variations in their luminosity which occur across the entire object, as well as jets suggesting superluminal velocities. Most likely they are not hypergiant-protogalactic star monsters, but are actually much closer, smaller exotic stars exhibiting an extreme version of this Barnard's effect.
No. Quasars have a finite reaction time to changes. See reverberation mapping. Showing the scale of the disk. Quasars are not close, they are seen behind galaxies and show no parallax. They also all happen to be aligned with the centers of galaxies of the same redshift, why would this be true in they were not distant and not associated with these galaxies? Jets do not suggest superluminal motion, this effect was predicted and is simply due to geometry.

>As if it were a single object, a galaxy's furthest stars rotate fast enough to keep a congruent shape compared to the innermost stars
No again. Galaxies have flat rotation curves but this is not solid body rotation (linear increasing, not flat) so they don't keep shape.

Because of the fundamental forces of the universe, and quantum mechanics. Really it all comes down quantum theory - if you don't have a good grasp of it you're not going to get much more than a dumbed down explanation. I found this blog post which does an ok job of explaining it to laymen

String theories is not part of the standard model. Not all, or even most physicist think of it as being the underlying phenomenon to particle physics. You also have to be very careful using the term dimension. While we often use it to mean spatial dimension, scientifically it just means the number of variables needed to describe something. These could be spatial extent but it could also be charge etc.

Theoretically they might. Instruments we have may be imprecise and unable to measure their surface. Quantum particles don't behave physically like other packets of matter, so defining any relative surface by their movements is tricky if impossible because it may not exist.

so im moderately drunk here so forgive me for the stupidity of this post and try to enjoy it as something to laugh at rather than get angry over.

I know nothing of astronomy, my knowlege of the subject consists of only shitty usually misinformed images im semi-knowledgeable in biology though, and that shits the tits despite being the lowest level of what i consider real science(fuck pych, thinking theyre not just bullshit)

apologies, more to the point. I've heard that theoretically, if you were viewing the universe from inside a black hole, you would see the universe from all time perspectives rather then in just the present. now as i've stated, i know dick about shit regarding anything outside of shit on earth BUT do you think what with time being relative and (if im not mistaken) the majority of black holes' properties being unknown, that black holes could be connected to the big bang or the "origin" of the universe.

(using this example because i can see the 1st image on thsi board is an hourglass. so maybe its kinda like the universe is an hourglass but the bottem of the hourglass is connected to the top (im gonna make some shitt ms paint right meow) with gravity removed from the equation thanks of black holes.

i dunno man, i hope you guys can decipher this post to some degree, as well as the image.Hope the ignorance is stupidity makes you laugh rather then become upset at my absurdity)

The no-hair theorem states that black holes are fully characterized by mass, electric charge and angular momentum. See http://en.wikipedia.org/wiki/No-hair_theorem, but also http://www.scientificamerican.com/article/black-holes-may-have-hair/

Just another crack pot idea on time travel, this would not be able to send a concrete object back in time, just decay particles from weak nuclear interactions.

But in theory could it be possible to entangle a w or z boson at the points marked on the diagram? Since the weak force does not completely obey the arrow of time, would this phenomenon be exploitable in a relatively high mass environment? just to get time going faster to get more information to the past, I don't know the math of the weak force, but would being in a field of higher gravity also magnify the frequency of the bosons time line?

I guess you would have to entangle it before it even existed, which im not sure is possible, but why not? It's not like quantum mechanics makes perfect sense to anyone

The wavey line is just how you draw photons, w and z bosons. It has nothing to do with it not obeying causality or the arrow of time.

What Fred said. Also, what do you want to entangle it with? Nothing is interacting at the marked points.

It's interesting that you mentioned entangling a particle before it exists - the nonlocality of entanglement isn't limited to spacelike intervals, it can apply to timelike intervals as well - see http://www.extremetech.com/extreme/156673-the-first-quantum-entanglement-of-photons-through-space-and-time.

I just had the idea that time becomes more consequential the smaller of an object you observe.
Many quantum effects have zero time dilation
Atomic effects have whatever incredibly small fraction of interaction with time
Molecular effects operate on the range of seconds
Macro objects and change over minutes
Large masses change over years
Stars change over thousands of years
Galaxies noticeably change over tens of thousand of years
Galaxy clusters interact over millions of years
and galactic clusters interact over billions of years.

Am I just high, or would their be a way to correlate the size of a defined system with the Einstein field equations?

The smaller something is the less efficient its surface area to space occupied is (Not mass, The actual amount of space it occupies).
As such, Reactions are more likely to happen.

So you know, I'm a scientist by education (biologist) but haven't ventured into astronomy or astrophysics to any significant length and have been content more or less by the information I've gathered regarding the creation of the universe, planets, elements, and complex life in general. However, what I don't particularly understand is how it reinforces atheistic predilections by providing explanations to natural phenomena. I'm an atheist by nature and was having a casual conversation with a friend of mine who's also a scientist (chemist), and it was an odd conversation to say the least.

My overall take on the matter is that solid theories and data and evidence regarding the conception of life is so relatively coherent that to put an almighty and all-powerful, sentient, entity in the story is just redundant and superfluous, but taking a chemist's point of view I saw some holes in some of the information I have that make up my outlook on things. When it comes to life, it's quite easy to explain how it was formed, at least on earth. However, what he was arguing about was not life in general but rather things that are atomic in nature; he asked how protons and electrons came to be, and the quarks and muons/taus/so on and the overall complexity of what people see as the most simplest of things in the universe. I don't really have the necessary understanding of physics or the universe in general to come up with a valid answer. Obviously there are valid explanations for them, and a lot of theories too, but what are the most recent and most credible? And, I'd really hate to do this, but for some odd reason, he said that matter must be preceded by a something, from an incoherent state to a coherent state, and then explicitly stating that even if time provides the necessary tools for coherence, something must have created all the matter in the universe which came from the big-bang.

Oh I don't know, can anybody point me to decent reads (not books) regarding question of why did the big-bang happen, and where did all this matter come from, and why is there an infinite universe to allow for its expansion, the assimilation of quarks into protons and electrons and atoms, and s…

This is most likely correct, consciousness being primary to matter and having created it. This has almost nothing to do with God and more to do with how you conceptualize our 3d reality being simulated within 4d Bulk space, embedded within it like a Russian doll. The simulators would have "thoughfully" created the conditions to form 3d matter.


Given the universe is a vacuum fluctuation, what are the chance it does exist? by Stephen Hawking - Sat, 12 Jul 2014 21:55:01 EST ID:/JyFBi6b No.54103 Ignore Report Reply Quick Reply

I just found about the zero energy universe hypothesis.
http://en.wikipedia.org/wiki/Zero-energy_universe

Now the obvious question is we have some theories about the probability of vacuum fluctuations. And we have estimations about the total mass of the universe.
Given that can we express the probability in standard base exponential notation?
Anybody feel up to calculating that number?

every time you propose a mechanism explaining the creation of the universe thats rooted in physics you assume exactly that.
the universe from nothing hypothesis, apart from misusing the word nothing, as nothing cant have properties, is based on this assumption, which you said yourself is unjustified.

No it doesn't, in fact many of those models use different physics which can be shown to produce our physics.
All models make assumptions. In this case they are currently unjustified but that doesn't make it wrong, it makes it a hypothesis.

what doesnt what?
if you use different, not experimentally tested physics to explain things, youre getting even further removed from verifiable, falsifiable science. of course nothing wrong with hypotheses, even those that cant be falsified (like the God hypothesis). they simply should never be presented as knowledge.

>youre getting even further removed from verifiable
No, all verified theory starts as hypothesis. That doesn't make it untestable. Using up established physics doesn't make it wrong.

That's wacky. Even wackier is that they found it in a bunch of other clusters, too., which makes it sound "common." That's a game-changer if dark matter actually has a spectral signature.

Can we call it anti matter or is that an entirely different thing.
Or what, are we going to eventually have dark/light matter reactors?
Matter anti matter reactor sounds better.
Warp core sounds even better.

Scientists can't get called on plagiarism when some sci fi thing ends up being pretty accurate to real life right?

It's definitely not the same thing as antimatter. We know how to create antimatter, and have done so in small amounts in particle accelerators, even if it doesn't exist for very long (once the particle comes in contact with normal matter particle, they annihilate one another). Dark matter/dark energy are pretty exotic types of "stuff" that we're still trying to figure out.

That said, there's an idea that antimatter could be an energy source, if it could be contained within a magnetic field and basically allowed to contact normal matter one particle at-a-time, which could be the "reactor" idea. I think that's the basic premise behind the Star Trek warp core, since every time shit hit the fan, they always said "we've lose anti-matter containment." So... who knows if it would work, but there's definitely theory behind the idea.
