If you kept travelling across the universe in one direction would you eventually be back where you started?

NO.\nTechnically speaking if you travel on the earth in on a single vector you would not end up in the same place because in order to do so you would be constantly changing your vector. Technically speaking.

I will do it to satisfy my curiosity. A free trip in the space to discover other inhabited planets and galaxies is a dream come true. It is an occassion not to miss out but i would not go for ever because there can't be no better place than our home. I will return back to earth after the trip to my home sweet home.

in a sense everything you go by is moving in reverse....\nit is travling behind you and further away

You would have to overcome the spinning motion of the atmosphere.  See my answer to your "if the world stopped spinning" question.  So yes, if you could reach about 900 mph going west, you would be counteracting the spinning of the Earth and eventually be somewhere else "without moving".  Now about the Earth's orbit around the sun...

Depends. You want to go forward or back. \nI *cough* actually have an entire theory about time travel. \nAnd that is, that there can only be one of you in existence at a time. Thus- if you go forward your putting yourself in your future self's body. And if you go back your putting yourself in your younger self body.\nBut- if I'm wrong and quantum physics 'same thing in countless positions at the same time' is right. Then you can be in two places at once. Therefore time travel- where you keep the machine and keep yourself how it is now, is possible. Then... I have no idea how you would go about it.\n\nIf anyone tells you to plug in the toaster and stick a fork in where the toast is supposed to come out though. Don't do it. Them electrical burns hurt.

I would think that you would spiral toward Australia and then back toward us with the mid point at the center of earth's mass, each time not going as far as before .  \n\nThe reason that you would basically oscillate like that, is that the force of gravity increases the closer the centers of mass are to each other (the closer you got to the center of the earth) and so you would be accelerating the entire way till you got there and you would continue going because there would be no force acting on you to decelerate you.  As you start going away from the center toward the land down under, the force of gravity would act against your current velocity, till they cancel each other out and you start to fall toward the center of the earth this time the other way.  The reason that you would not quite make it out the other side of the hole is wind resistance and other very small forces would be affecting you. \n\nAssuming I'm right, you would eventually end up rotating in 3-dimensions around your stomach (or where ever your center of mass is) at the center of the earth.

You would go until you died of course. Assuming you'd never die, you'd never stop travelling in that spaceship. That's what infinity means. It's hard to grasp that idea, but space never ends...

Time travel is very possible. You are travelling in time right now, but just at a slow pace.  If you move a lot faster than someone else you will be travelling in time slower than they are.  But if you travel at 95% of the speed of light for 10 years (relative to you), you'd have travelled 11 and a half years relative to someone who is not travelling with you!  This is due to a phenomenom called Time Dilation and is part of Einstein's Theory of relativity.  \n\nYou could say you have travelled 1 and a half years in the future over 10 years.  If you travel even closer to the speed of light for the same amount of time you would have travelled even further into the future.  The equation for time dilation is T=T(0)/(sqaure root of(1-(v/c)^2)).  Where T is the time according to someone staying still, T(0) is the time according to you, v is the speed you are travelling, and c is the speed of light.\n\nTravelling back in time is not yet proven to be feasible but it is thought, by many major scientists believe it would involve bending the universe (which may or may not be possible depending on the type of universe we have) or travelling to a parrallel universe, which would really on have the affect of time travel.\n\nOne major flaw of all these is that returning to the time of your original place is impossible or hard to do.

Time would conquer you. considering that to all outside observers you would vanish. From your viewpoint the entire universe would cease to exist even if you were to slow down now you would find yourself in a limitless and absolute void with no reference. You would be in absolute solitude.\n\nTraveling at relativistic speeds (fractions of the speed of light) distorts time relative to outside observers. time/the inverse of the factor of c.\n\nIf you were to travel at 1/1,000,000,000 the speed of light 1 second to an outside observer would only be .999999999 seconds to you.\nIf you were to travel at 1/2 the speed of light 1 second would be .5 seconds\n\nI believe that this maybe one of the thoughts that lead Einstien to the statement "Time is an illusion, although persistent, still just an illusion.

Yes, you would be upside down.   You'd get lighter and lighter as you approached the centre of the Earth.   As you continued towards the opposite side, your weight would start increasing,you'd start to feel upside-down and you'd reach the other side feet-first.   If I tried this, I'd turn myself through 180 degrees when I reached the centre.   It would be a whole lot easier.

Imagine a situation where you would come back to your starting place no matter which direction you go as long as you kept going far enough. This is true, for example, on the surface of a sphere. But it turns out that there are analogs of this for going any direction in three dimensions. In this case, the universe would be finite (like the surface of a sphere), but would have no boundary (again like the surface itself). This is actually a simplified version of the models used by physicists for describing a finite universe. In reality, the evidence suggests that the universe is infinite.

since you said "IF",  I think somewhere around the middle gravity will reverse on you and you will have to turn your body around so that you can come up on the other side head first.

congratulations, your a strong character. i think you would be mad to go back to the way you was after all the hard work you have done. just keep taking one day at a time you can do it.

nice question  theoretically you would be pulled in every outward direction, which would be interesting.

No.  You'd need to have a wormhole.  Current theory predicts that transversable wormholes exist but would not allow time travel.  See reference for details.

yes, you would. but why is this relevant. you can't step out of the universe.

Even if the universe does curve around, maybe you'll see the side of your head.  I'm not sure how distorted it would look either.  Like a previous poster said, you'd have to wait until the light made full circle so you'd be dead by then.  You'll have to leave a passdown for the next shift.
