The universe is expanding.

That means all the distant galaxies are moving away from us, and eventually they'll be moving away from us faster than the speed of light. (its allowed in general relativity)

They will disappear.

The longer we wait, the less we will see.

In one hundred billion years any observers evolving around a sun will see nothing but their galaxy.

All evidence of the Hubble expansion will have disappeared. Why? because we wont see the other galaxies moving away from us.

So they will have no evidence of the big bang.

Those scientists will discover quantum mechanics, general relativity
They will discover evolution, and all the basic principals of science that we understand today, use the best observations they can do, with the best telescopes they will build and they will derive a picture of the universe which is completely wrong.

They will derive a picture of the universe that is one galaxy, surrounded by empty space which is static and eternal.

Falsifiable science will produce the wrong answer.

We live in a special time. The only time we can observationally verify that we live in a special time.

 

not necessarily, we still dont' know if the universe is gonna end up closed (where gravity is a little too strong, and eventually will halt the expansion of the universe and pull everything back in on itself, eventually become another singularity and start the whole process over again) open (where gravity is a little too weak and you described pretty well above) or flat (when gravity is perfectly pitched at critical density, allowing the universe to hold itself together at teh right dimensions to allow things to go on indefinitely)

 

no one knows whats going on in space. period.
if you trust the news casters who trust the astronauts (lord knows if they even go into space or are just good at making fake pictures), youre trusting THE MAN.
we are hippies, we dont trust the man.

 

in one hundred billion years the sun will have exploded

 

Being hippy doesn't mean that you should blindly ignore the outside world.
The skies are not under government control and anybody can point a telescope at them.

Regarding the OP's post, generally speaking, extrapolations should be made with care.
As for Hubble's expansion, it is a not directly testable theory and I expect it will be further revised over the course of time, to account for the various anomalies, assumptions and improvements in measurements.

 

That is what I mean by naive'.
Unless of course it was purposely meant as a joke, then you signify that by adding at the end.

 

its the truth. why would i believe something someone says just because 1. everyone else does and/or 2. because someone has a degree in ___ and "proves" it.

 

Because the data is available to all (more or less), their methodology is copiously documented, and (at least) tens of thousands of other people from around the world have been pondering these issues and scrutinising each others' work.
In short, science.

I don't know what the universe looked like 5 billion years ago, or what it will look like in 5 billion years (or just 5 lol). But this is what it looks like now.

 

i thought we were talking about the eventual (final) state of the universe and the effects it's own gravity have on it?

i'm no physicist (i dont' believe physics is worth the paper it's written on) but a spherical universe suggests to me that in x billion years we will have a flat (or goldilocks) universe... it has to be turning it's own energy in on itself and eventually meeting it's own energy at curvature point for some reason... but fook knows

 

:rofl: Thank you for that bit of comedy, it brightened my day a little.

 

What gets me is that eventually the galaxies themselves will change/dissolve/spread apart . . . . imagine living in a Universe that is so old, so distant, so expanded and spread out that all you ever see in terms of "light in the sky" is your own star/sun or moon(s) and planets that share the star . . . Other than things in the immediate system, nothing but endless BLACK, everywhere, everywhen, forever . . . Kinda creepy in a general way. Frankly, i'd be lucky to be alive 50 years from now!

 

We'll have a new idea by then.

 

I wouldn't be surprised if the universe expansion is a dispersal rather than a complete dissapearing act. Like seeds falling from a tree.

 

No doubt the universe is expanding faster than kirstie alley at a hollywood buffet; but unless we evolve and ascend before the sun completes its expansion phase - we might as well put butter in our pockets because we're all toast

If someone else has already stated this, I apologize for the repitition, but I'm way past to wasted to give enough of a crap to read the whole thread--

Acorrding to Relativity, as the relative speed of expansion approaches the speed of light, the mass undergoing acceleration is subjected to both a Mass increase and a Time/space decrease.
Although the receeding galaxies will, relatively, approach C, they cannot even IN THEORY exceed that speed. Instead, they will become thinner and more massive.

Relativity states that Infinite energy input is required to exceed the speed of light.
But since infinity is a null concept, we must scratch our heads and come up with Quantum Theory, which explains things that Relativity does not (and vice-versa), and wait for some post-Hawking Genius to Unify Relataivity and Quatum Mechanics.

 

c = 299,792,458 m/s.

 

Can you feel It?

 

We can only view the universe as it was billions of years ago.
The farthest viewable galaxies appeared to be receding 12.5 billion years ago, there is no way to even tell where they are now. This must always be kept in mind when talking about this special "time" we are experiencing.

Our window of the universe is a very warped speck approximately 25 billion light years in diameter. What we can see is probably something like to trying to read a website with only one little pixel working on your monitor screen.

 

Awesome...

Except Time itself has no relative Zero except the "Big Bang". It's called "Relativity".

And it's "km/s" not "m/s".
