Is the universe shaped exactly like the earth?

Question

If you go straight long enough will you end up where you were?

Answer 1

and thats how the world began, and thats how the world will end.

the universe is actually shaped like one of those penny funnels everyone in the mall uses to donate money. slowely but surely we will spiral down that small hole and get donated to the salvation army.

Answer 2

The surface area of the Earth is finite and it is determined by the formula 4¶r2 where r is the distance we travel when we dig straight down to the centre. If a modest mouse scampered along the Earth's surface, never changing its direction, it would indeed end up back where it was.

Similarly the volume of the Universe, at any given time, is finite. Therefore its size in three of the four dimensions of spacetime is determined by 4/3¶r3 where r is the distance we travel when we go instantaneously (as in through a wormhole) in any direction from where we are now, out to its edge.

But here's where it gets tricky: We know that spacetime curves into the 4th dimension, but we don't know what shape it ends up as: a saddle, a four dimensional flat dimpled surface, or a four dimensional sphere. In the last case, the mouse going straight through the universe long enough would indeed end up back when it started... just as on the surface of the Third Planet, it would end up where it was.

Answer 3

No. You will end up where you are.

In the first place, no shape has ever been claimed for the Universe. And secondly, there is no proof of the theory that you imply that space is curved...

At this time I can tell you that scientists and astronomers can see distant objects in deep space at a distance of 13 Billion Light Years in all directions from Earth using our best optical telescopes. Using Radio Telescopes scientists can detect objects in very deep space at distances of 40 Billion Light Years in all directions from Earth. Nothing whatsoever suggests that space curves back onto itself. If it did, stars and galaxies which are moving away from each other at utterly fantastic speeds would have completed the loop long ago and begun flying past us as we sit here poking along. That has never been reported or observed has it...nope, it hasn't. End of lesson.

What we do know is that space is vastly deep and unbelieveably huge. Most people lack the ability to think
in terms as large as multi billion light years because they
lack comparitive experiences here on Earth where all their knowledge was based upon finite things which had a front and a back, a top and a bottom, etc. Space is not the Earth. No one ever said it was. So Earth related experiences are no help in discussions of deep space.

Now since we know that our learned professors can "see" in a straight line out to 13 Billion Light Years Distance and "hear or detect" things out at distances of 40 Billion Light Years that means that space is at least that large "in all directions." Since the distance figures they quoted to us were where their equipment failed to provide any further useable information, that does not mean that space ends there...it just means that their equipment crapped out at that point. In the years to come maybe some new technical developments will surface which extend our "Seeing" and "Hearing/Detecting" capabilities out to 50 - 60 - and 70 Billion Light Years distance. We will just have to wait and stay tuned to see if this happens. For now it is sufficient to say that based upon what we already know, space continues for a long, long distance beyond, and there is no indication, whatsoever, that it curves, twists, or loops back in some phenominal ring, spiral, or convolution. It just extends outward in all directions for vast distances.

Answer 4

No you wont end up back to point of begining,, You would just go on for infinity,, there is no up, down, left or right,, or a curve to set you back to POB

Answer 5

No the universe is infinite therefore you would just keep ending up somewhere else.

Answer 6

I think I'm the only one that gets this inside joke.

Answer 7

thats a good song

Answer 8

nope, its a plane, not a sphere

Answer 9

no
