The Known Universe

[jluetjen]

Very Cool!

If you enjoyed that, here's another classic. Even if the music is not Elmer Bernstein's finest composition.

just guesses.

And who thinks the known universe is in the shape of a sphere? A very simple model to be polite.

Overall it was cool, guess I'll settle for the moon orbit shown in lieu of the moon.

Actually, the known universe is a sphere almost by definition.

"known universe" is very different than "Universe". The known universe is the realm of 3D space that we can see photons from, where the edge of it would be the photons from the Big Bang.
Since the universe is isotropic to several places after the decimal, a sphere is an appropriate shape for it.

I feel very insignificant now....but I could listen to Philip Morrison all day long.

Both very cool. If Charles and Ray Eames, from whose offices the second film came, don't ring a bell:

And the unknown universe is infinitely large, yes?

If it weren't, what would it exist within?

Was there no universe before the big bang?

Or was there just no universe as we know it?

If the former, within "what" did the big bang occur?

If the universe is infinitely large does "large" have any meaning?

Are parts of the universe infinitely small, rendering "small" just as meaningless?

Can the infinitely small reside within the infinitely large?

Or are they the same infinite space?

How long did it take for the camera/space ship to go from the earth, out all the way and back to earth? And what kind of camera/space ship was it?


















































J/K!

Beautiful piece of science and art. Thanks for the link!

it was no space ship - just a remote camera on a really big rubber band


I used to show Powers of Ten to my Freshman Biology classes.

That we are such tiny specs can make one feel insignificant. On the other hand, the fact that we humans have the intellect to understand the universe across 40 orders of magnitude makes us far from insignificant.

What makes you think we understand it? We don't even know what the hell it is.

We are as insignificant as it gets.

We?

Sure we know what it is. We just don't know how it got here.

How can you say we're insignificant when we've invented the motorized bar stool?

And the unknown universe is infinitely large, yes?
By definition, unknown


If it weren't, what would it exist within?
a hyperverse

Was there no universe before the big bang?
there is speculation that the visible universe in which we live is a sort of quantum bubble derived from a larger multi dimensional hyperverse, along w/ ours there are speculated to be an infinite # of other so called bubble universes w/ varying physical properties, the one we live is anthropomorphically friendly to our sort of life

Or was there just no universe as we know it?
see above

If the former, within "what" did the big bang occur?
see above

If the universe is infinitely large does "large" have any meaning?
only relative to something else

Are parts of the universe infinitely small, rendering "small" just as meaningless?
no, there is a limit to smallness too, the Planck length is speculated to be the length at which reality becomes dominated by quantum effects giving it discrete structure

[DARISC]

Thanks Bill.

NOW I understand!

[krystar]

if u have an hour to burn and interested in astronomy cosmology and the such. AWESOME lecture!

OK, define the universe. Enthrall me with your knowledge.

Of course you realize "speculated" is just another word for "guess."
