If I were capable to travel to the end of the universe, what would I hit or see?

Jeffrey K say: The universe has no end or edge or boundary. That would violate general relativity. Space is either infinite or finite but unbounded. It could be the 3D surface of a 4D hypersphere.

In say: You can't, so leave the dreaming to the physicists and sci-fi writers.

Zardoz say: If you were instantly transported to the event horizon of our universe you'd not be able to tell you weren't in any other unfamiliar neighborhood anywhere else in the universe.

Smith say: The size of the universe is measured by the light that reaches Earth. Since no light means that's the end of the universe (or close to it), you will just be traveling into a dark void. Of course, your body and your spaceship will be ripped apart in a second and scattered into atoms.

Starrysky say: Travel through distance to somewhere the universe "ends" (where there is no more universe)? Or travel through time to when this universe dies?
Distance answer. Not possible. The forefront of the wave of creation started by the big bang is too far away now. And because of that great distance, the "edge of the universe" is moving faster away from us than the speed of light. How can it move faster than light? The edge itself is not moving faster than light. But all the intervening distance is all expanding. The distances between each galaxy are growing because of the property of expansion of space. By 72 thousand kilometers every second for every megaparsec of distance. And the rate is getting faster, due to "dark energy". So the edge of the universe goes away from you and me faster than the speed of light. Can never catch up, since no matter or energy can go faster than light. Bye, bye. Then you grow old and die.
Time traveling answer. As far as going through time, you would not have to move. You would not hit anything. Something from outer space might hit you. Or the sun swells and consumes Earth. If you are still alive, you die. The end.

CB say: The top of a petri dish. This whole universe thing is just a huge experiment in a much, much larger world.
