Amazing Animation About Our Universe

There are things in our universe far beyond human comprehension.

Imagine what the first space explorers will say when they see some of these giants up-close.

:shocked:

 

[Fritzo]

This has been done to death over the last year...

Much better here in fact.

"up-close"? Probably something like "AAAEIIIEE IT BURNS!!! <end transmission>"

 

[Mo0o]

Hard to contemplate the size of these things

 

[Cristatus]

I never knew there were such large objects.

I had heard about supergiants and all, and I'm sure my HS physics teacher talked about their sizes compared to our, but it doesn't really hit you until you put them into perspective like this.

That's nothing, the universe is what, 13.5 billion light years across? I've actually been enjoying the show The Universe. Never really had much interest in this stuff until I saw that show.

edit, it's actually 150 billion light years (so I was off by a few billion...) 13.5 billion is the age of the universe.

 

[ChAoTiCpInOy]

Wow that was cool. Very slow to unfold but wow sometimes you just have to put it all in perspective.

 

[everman]

Kinda like the Total Perspective Vortex.

 

[homercles337]

D00d, im so serius about this, but we am ants on ass on teh grend scale! /thred.

You know what bugs me about that? What was there before the universe?

What's south of the south pole? The theory is that the Big Bang was an eruption of space and time - causality because of time like we know it didn't exist.



Powers of Ten is another good video for various scales of the Universe, from the very small, to the very large.

That which is and always was and will always be. Wal-Mart.

Nothing, you are the farthest south you're going to get. Unless you stay there long enough for the magnetic pole to shift, that's it.

Ok, so that theory has nothing in existence before the Big Bang? So what caused the Big Bang then - if there was zip, zero, zilch in existence? I realize this isn't an easy question but I feel like that theory is awfully easy to shoot holes in.

There was no "before".

It's asking a question beyond our experience. It's like asking a blind guy if the blue looks better than the red. All we know is a universe with 3 space dimensions and a time dimension. We think in that manner. It's not really within our ability to conceive of something besides trivial additions and subtractions to that (we can do physics in a 4-D universe easily, we actually DO physics in 1 and 2 dimensions all the time, but we always need time in order to have a before and an after).

Roger Penrose gave a talk at my school a while back and someone I know went to it. He said Penrose put forth an interesting theory of the universe which went like this:

So say the universe evolves for a long long time. One possible "end" to the universe is that all matter turns to energy and the universe is nothing but a huge photon bath. Because everything in the universe is photons moving relativistically, time and space really don't have any scale at all anymore. Thus, you can re-normalize the universe to be a point, and then you get a new big bang.

Energy could be considered matter, so where did that come from to form the first big bang?

I know that we will never really know for sure, and that is why it bugs me when people say stuff like, "it was always there", if you don't know the answer just say it instead of making up something to smart say.

Not really. If you're moving at c, the time dilation is infinite. An instant for you would be a universal lifetime for someone at rest. Time would have no meaning. As soon as you add mass that all changes.

All explanations are theoretical, and extremely hard to explain to someone who doesn't have some knowledge about space-time and string-theory. Get your feet wet; try wrapping your brain around this video about the first ten dimensions.

We already have concrete proof that time can be distorted by space, and that time is relative; the dozens of GPS satellites we have in orbit have on-board clocks that have to be corrected to "Earth-time" dozens of times a day because time moves slightly faster in space. The Earth itself distorts the fabric of space-time enough that we can measure a difference between time on Earth and time in-orbit.

So when you ask what existed "before" the universe, you're delving into highly theoretical mind-f**king physics.

Not so Mr. Cho...check out Brine theory and why physicists are starting to believe there are multiple universes floating around as bubbles. When two universes collide their brines mix to create a new universe, with it's own unique laws of physics. Mind blowing stuff.

 

[DanTMWTMP]

damn this thread is too deep. Due to this thread, I searched wikipedia for all kinda of information and theories.

*head explodes*

I know about string theory thanks. I also know that it has 0 experimental backing thus far

And you meant to say "branes".

 

[aplefka]

This thread is sweet.

Precisely my point.
Asking "What was before the Big Bang" is like asking, "what is south of the south pole?" Both are like the "endpoints" of a sphere.

(And no matter how long you sit at the south pole, it's never going to change. The south magnetic pole will change, but the south pole never will, at least not until Earth somehow disintegrates in the very distant future, once its protons start to decay away, or when Q decides to vaporize the planet. )

Ok, so that theory has nothing in existence before the Big Bang? So what caused the Big Bang then - if there was zip, zero, zilch in existence? I realize this isn't an easy question but I feel like that theory is awfully easy to shoot holes in.

The theory has "something" in existence. Fritzo was a vowel off - brane theory. Massive structures out there somewhere collide, and the result of this impact is a tiny bubble of spacetime, complete with concretions of energy, and even more densely packed stuff - matter.
