POLL: Do you know how far is up ???

Question

Thank you. Where does it start and when does the universe end ??

Answer 1

up is above your head and the universe is infinite

Answer 2

I would consider up to go as far as the end of our atmosphere and the beginning of space.  There is no up or down in space.

Our known universe is 156 billion light years across.  We don't know what is after that.  If you mean when in time, no one knows.  Some believe that the universe will expand for a certain length of time and then rebound in a Big Crunch.  Others believe it will continue to expand.

Answer 3

infinite

Answer 4

Sure do Phil...sure do !!!!!!

Starts at one heart and ends at another.

Answer 5

The universe never ends. It's infinate. No beginning, no end.

Answer 6

"Up" is a direction and doesn't express length, so your question is invalid...  Sorry!!  [[Deduct 20 points]]

----------------

For the term "up", the reference direction is the center of the earth as is the term, "down" which refers towards the center of the earth.  When you leave the reference point of Earth, "up" has no meaning unless there is some agreed upon reference point - as the "bottom" or "center" of a spaceship, or other celestial body such as the Moon's center.

Your question, "When does the Universe end?" goes in Astronomy and Physics, but if asked metaphorically in Philosophy, and maybe the Poetry part of Literature.  See you there!

Answer 7

'Up' is only an earthbound term. Once you leave the atmosphere  and are not orbiting the planet, there is no up, down or sideways.

You are simply traveling.

Answer 8

I barely know which WAY is up, personally, so I get all my stuff from wiki. Are you sure this is "Geography" btw? Isn't it Physics, or perhaps Philosophy?

Anyhow, Wiki has this:

http://en.wikipedia.org/wiki/Universe#Si... Please skip to "size" and see if you think that's an adequate answer.

Answer 9

there is no limit to up. it is as far as the universe reaches.
