what is the length & breadth of space ,at one point it has to come to an end.what exists after that point.?

Question

In science we study that the length and breadth of space is infinite.my question is what is approx length and breadth of space.it has to come to an end at one point.and what exists after that point.?

Answer 1

There is no end to space, and beyond whatever you label as the end, would be more space. Who says it has to come to an end? Whoever they are, they are wrong. It is truly infinite.

Answer 2

If you ask, "what exists after that point?" it means you don't really think it has to come to an end. If you did think it could come to an end, you would not ask such a question; you would simply say that is the end.

But modern science says that 3 dimensional space is curved in a higher dimension (maybe a 4th dimension) that we cannot see. This is analogous to, but not really similar to, the curvature of the two dimensional surface of the Earth in the 3rd dimension. It is not similar because we are really 3 dimensional beings and we live in and can experience all 3 dimensions, length, width and height. But 2 dimensional surfaces have only length and width. The area is measured in square miles while space is measured in cubic miles. The 2d surface of Earth has no edge, like a flat piece of paper has edges, but it does not have an infinite number of square miles. You can go for millions of miles in what you think is a straight line and never reach any edge. But you will circle the globe many times and pass the same landmarks again and again every 25,000 miles. But you would have to remember those landmarks because you cannot see all the way around the world. But you can see the 3rd dimension. You can look up and see the stars. You do not really exist IN the 2d curved surface of the Earth. Now in the 3d universe which is curved in a higher dimension, you really do live in 3 dimensions. You cannot look in any direction the looks out into the 4th dimension. Buy you could, in theory, travel in what you think is a straight line for billions of light years and never come to any end to the universe. But you would "circle" the universe, passing the Earth many times as you do so. But you cannot see all the way around the universe, so you would have to remember what the Earth looks like to recognize it each time you passed.

So, given all that, where is the edge? It is right here. Just like the edge of Earth is right here. Every time you jump up, you are jumping off the edge of the Earth, but gravity always pulls you back. But you cannot jump out of the universe, or even look outside the universe. You would have to look in a direction we cannot imagine. Not up or down, not right or left, for forward or backward, but another direction we cannot ever know.

Answer 3

the universe is expanding faster than light. this does not contradict the theory of relativity, because the object isnt moving faster than light, space is merely expanding faster. when we look as far as we can see into the universe, we are seeing what was formed shortly after the big bang. past that point we cannot see because light hasn't reached us yet. if space is indeed infinite (and why not?) then the size of the universe is how far the universe has expanded, and past the boundaries of the universe would just be empty space. except this wouldnt be your average vacuum, because it would be devoid of energy as well. these vacuums are believed to have special properties. there is no end to space though. space is infinite, therefore impossible to measure. the size of our known universe however is about 36 billion light years.

Answer 4

The universe is not a room. It doesn't have a wall, floor, nor ceiling. You can't point to "outside" the universe. You can travel in a straight line forever, and never reach "the end." If enough matter exists such that the universe curves in on itself, then that straight line you're traveling would eventually lead you back to your starting point. I'm not sure I subscribe to that eventuality, but right now - it's unknown.

Answer 5

it does not have to come to an end actually. you are thinking like the ancient greeks where everything had to be like it is on earth, on earth everything ends, except the earth itself, a sphere has no end, the universe is like that, except open, it has no end, you can never reach the end, even if you were talking timewise you can never reach the end of the universe because it won't stop it will die an extremely long death until there is nothing.

if i hop into my star ship and warp 9 myself to ten billion light years away, i would look around and see the universe exactly the same as i see it right here.

Answer 6

It goes on forever. he length in miles is infinite. That means, no matter how far you go, you can always go 1 mile further. If you can prove that space must come to an end, you will be a famous and wealthy person.

Answer 7

The statement that space is infinite means that it has no measurable length or breadth. No limits, no beginning, no end.

Answer 8

lol namastey! returned Richard is nice, you ought to take your meds Why dont you tell the L/B/D your self once you have travelled some distance previous the prevalent. You 'Swamy' human beings have spoiled India as much as pope and mullas have spoiled the west and arabs. Take your gay philosophy away formerly i discover you beat you out of India

Answer 9

Sorry, we don't have a tape measure that long.

You need one that can measure infinity.

You ask questions that are unfathomable.
