It just is. That's the nature of things. Stars are circular, planets are circular, orbits are circular.
If the big bang theory is correct that matter was spewed out as an expanding sphere. Round. Circular.
Now, it is only THEORITICAL, but Einstein, you know, the man who said the A bomb was possible. You know, like, we've proved a few of his fables already time and time again.
Well, Einstein says that if you take off in a rocket in a striaght line you end up coming back to where you started.
This is, theortically, caused by a warp in trajectory called the TIME SPACE CONTINUM
As we travel through space we travel through time. As we travel faster in time space begins to become deformed -- well actually we begin to become deformed -- no one is really sure, it's RELATAVISTIC thinking. Which means that I'm flying next to you only slower and I can see you are more compressed than before, but taht's only my REALTIVE view. I am also compressed.
So anyway this warping of time and space (proven partially, by the way, by observations at Lunar Eclipses in which light from stars BENDS near the sun due to the SUN'S gravity).
You see, gravity, inertia, thrust all react with TIME SPACE physics at great speeds and yo uneed great speeds to escape EArth. AT least 20,000 MPH.
Now, in theory when you travel in a jet aircraft you are also subject to TIME SPACE problems, they are just so minor you can't obesrve them. Like 1/1,000,000 of a second off in time.
NOW
Also remember that the EARTH, the SUN and the MILKY WAY galaxy are TRAVELING in SPACE and time.
The milky way and the sun are probably traveling at about half the speed of light!
Yes. Right now we are moving at HALF the speed of light, we just don't sense it.
It's the moving elevator concept. You feel it when the elevator starts, but once it gets goiong you stablize.
We are moving away from the BIG BANG at a speed anywhere from 25,000 Miles PEr Second PEr Second to 110,000 miles per second per second.
The EArth is probably two or three times larger at rest than it is in motion.
The sun is probably two or three times larger at rest than it is in motion.
As we move that fast, we shrink in size.
Time and space dialates.
So you go off in WHAT you think is a straight line, but the relativstic universe has you fooled and you are on a CIRCULAR path.
The only way you can get past all of this -- AN STILL YOU MIGHT END BACK WHERE YOU STARTED -- is to step outside of the exiting TIME SPACE continum and see where you reall are and what object is going off in what direction.
The problem there, is can you survive going from 100,000 Miles PEr Second to 0
More important, can you get back to up 100,000 miles per second!
When we travel from the Earth to the Moon we are moving at 20,000 miles per hour in our STATIONARY RELATIVSITIC UNIVERSE, when actually we are probably moving 100,002 miles per per second for that frame of time.
In short, we are like the ANT walking the Earth. They start in NYC and walk west and eventually they come back to NYC.

Well, this is assuming that the universe has boundaries. Supposing it does, a person would suppose that the universe doesn't just end at a direct point and then drop into something more than nothingness, because space is already as empty as it can be. It would have to be a spherical shape, so that it doesn't have edges. Now, you can compare it to running around in a circle. Think of it this way: If you start going straight east in New York, and never make any turns and just go straight, you would eventually end up back in New York.

we do not comprehend. The fastest you should probably commute (with our modern-day information of physics) is somewhat below the speed of light, say ninety 9% of c. the variety of the universe continues to be an unanswered questions. maximum theories may agree that you gained't hit an area. If the universe is open, you'll proceed shifting farther and farther out of your element of foundation, not in any respect lower back seeing the Earth. If the universe is closed, it ought to correctly be available to loop each and every of how round and finally end up lower back the position you began.

It is not a circle and you would not eventually end up where you started. It is however unbounded. The Universe is like the surface of a balloon analogy is not perfect. One of the misconceptions it causes is your question.
