The universe?

[Mohrenberg]

So the universe is expanding?
What is the universe? are they referring to the known galaxies or everything, including all space?

If they are referring to all space, then the universe must have an end, and what is at the end of it?

If they are just referring to the known galaxies and space is infinite......my mind is boggled.
How can something be infinite? Isn't there some law against this? Everything has a beginning, and everything must eventually have an end.

No one knows. There are a lot of different theories, each more mindfucking than the last, but there is no definite answer (yet ).

then the universe must have an end, and what is at the end of it?
.

I've been wanting to know the answer to that for years. I believe that their might be many universes, but until we can manipulate gravity, and pull energy from the vacuum, we will only be guessing. You also have the parallel universe thing..

I believe we have traveled outside of this galaxy, but any information on that would be classified.

if we can make things shoot into space i see no reason why we cant make a big big soace ship with a recyclable fuel source some sort of oxygen maker and lots of food send a few people on a big journey into space ( i voulenterr ) or maybe send a few "Wall-E" bots on an intergalactic journey

It is rather mindbogglingly if you stop to think about it.
Part of the idea is that space is expanding but that gravity is strong enough to hold planets at the same distance to/orbit the sun and each other. So most of the expansion happen between galaxies.

As for the end of it, I think it goes something like that there are no room for an end to the universe as that would be outside the universe.

I believe we have travelled outside of this galaxy, but any information on that would be classified.

Try make an FOIA claim on all files related to the StarGate project.
Here is the link.

That big spaceship would take generations to get anywhere, and would therefore be gigaton sized. A bit expensive to build, and the Orion drive have some complications in an inhabited system.

I think the universe is like the human body. We are atoms in a cell we call the universe. As with all cells, it will die, and be cast away, and then a new one created. Maybe the cell splitting is what creates parallel universes.

Or, we are on a huge hard drive platter. When one fills, another is added. I remember holding a new 4 gig HD and saying "This thing is a bottomless pit, there is no way you are going to fill it". It can only keep going up in size, so in essence its never ending.

It has to do with what observe. The ever slight red shift of the light of the stars could be a result of the universe expanding, or a result of the speed of light slowing down by the time it gets to us. Either case is just as likely, because for what we really do know, the universe could actually be shrinking.

Everything we can observe about the universe comes from information carried to Earth through some kind of electromagnetic wave. So ALL the bits of information we gather, could be that much off. If you want any other inofrmation to come from space, you'll have to wait for a meteor to come and pay you a visit.

And meteors don't like to talk about where they've been.

Who can know such things? (source?)

Just as the "rules" that govern quantum interactions are different from the rules that govern macro interactions, so the rules that govern, intra-galaxian interactions may be different than the rules that govern inter-galaxian interactions. Even these might be further altered by the rules governing inter-universe interactions or inter-dimensional interactions.

We only have our "observable" rules from which to view the universe.

What if the observable celestial objects and systems are not flying "away" from anything, but rather flying "toward" other things, but our perspective is too limited to perceive it?

It's all just an exercise to prevent us from raping and pillaging anyway

Peace,

if you want an actual definition of "what is the universe"... it is all of space that we can actually observe. So you can look at it 2 ways i guess....

1. our technology gets better every year so we can "observe" more, so it expands that way.
2. the very fabric of space is expanding.

but it's all greek to me LoL

I think the acid is starting to kick in.

Damn guys. I was really wishing to get some answers!
I've always loved watching things about the universe.

I've also got another question.
As a person approaches the speed of light, time seems to slow down.
Now assuming a person reached say, 180,000 miles per second, just under the speed of light, and through some miracle were able to fix a telescope on another person who is stationary, what would they observe?

would they seem to age super fast? I don't see how time can be altered. If it's really slowing down time, or altering the perception of time.
What if they carbon dated the spacecraft after the flight? would it come back and the correct age or still appear new?

I just wrote a three paragraph essay here that listed all I knew about your questions and read from various sources, but then remembered how much fun I had reading it myself. So if you really want to get a better understanding of these things get "A Brief History of Time" or get a book on tape and listen to it when you have some time or while using that Lathe of yours to make us some Laser hosts Also if you like some Sci Fi read Hard Science Fiction novels from authors such as Poul Anderson, Alastair Reynolds, Stephen Baxter and others Unlike the regular Sci Fi it is based on actual science

To answer some of your questions about a telescope: They would see a red shifted light reflected from that person and no they would not see him age super fast. But that person would be long dead by the time they see him. If they would carbon date the ship it would appear that it aged only for that much time as was experienced aboard that ship.
