+Park Joseph 1. Physically impossible

2. You'd have to slow down to turn around and this would cause time to pass extremely quickly on earth relative to your reference frame (from general relativity) you would return to Earth and see it many years in the future 

3. You mean an angular velocity equal to 99.999% the speed of light?

1. Yes, 2 years will have passed on earth. However, no time will have passed for you, since time does not exist at the speed of light. YOU will have traveled 2 years into the future, but nobody else on earth will have.

2. 2 years will still have passed on earth, but it will only be a few milliseconds for you, since time goes slower as you get closer to the speed of light. At 100% the speed of light, time stops completely.

3. The distance around the equator of the earth is 40,075.017 km, and light travels at 299,792.458 km/s. If you traveled at the speed of light once around the earth, it would take you 0.1336758 seconds. If you only traveled at 99.999% the speed of light, it would take you 0.1336772 seconds. It's amazing how the larger the number is, the more difference it makes when you take away just 0.001%! In either case, it will take you only about 1/10th of a second to travel around the earth.

MinutePhysics, I HAVE A QUESTION!
MinutePhysics, I HAVE A QUESTION!
MinutePhysics, I HAVE A QUESTION!
MinutePhysics, I HAVE A QUESTION!


1. Travelling at the speed of light,
if i travel for 1 year in the same direction, and
take another 1 year to come back,
How much time would have passed on Earth?
Will it be many years in future or would it be 2 years
since the day i left?

2. Same question as Q1, but what if it was
at 99.999 percent speed of light?

3. What if Im running around the earth at the speed of light
or at 99.999%, would it result in different answer?

I can see the difference between my left and right eye, when I looked at the small point of light while defocusing my eyes, and even the mini-rainbows! :)

Story
Tagline
Minutephysics: cool physics and other sweet science. On Youtube.
Introduction
I'm constantly in awe at the world. Isn't it spectacular? I like physics (and science in general) because the rules of physics, chemistry and biology apply regardless of opinion polls of scientists or the public. The goal of science is to find out how the world (universe, nature, etc) works by careful observation. It doesn't matter at all if you believe in a theory or not - what matters is whether nature works that way. A lot of popular ideas (for example, "the earth is flat") turned out to be wrong, and a lot of uncomfortable ideas (like quantum mechanics and plate tectonics) turned out to be right. It's a dictatorship – nature decides how nature works, and you get no vote! But you get to decide which questions to ask - and that's what makes science fun.
