Wow....... let's try this.
1) No. BUT it can appear to one not traveling with you that you DID travel faster than the speed of light. (see #3 below)
2) I thought oxygen DOES appear on other planets. Just not in a high concentration (20%) in a gaseous state in the atmosphere as we have on earth, due to differences in temperature, mainly.
3) You cannot see YOUR future by traveling faster than light, BUT (so the theory goes) if you travel near the speed of light, time for you will start running slower than time for the world outside that is NOT traveling fast.
-To you (traveling very fast) it would seem that a year has past, but when you stop and get out, you suddently find that 10 years have past outside. You would see the future of the world around you, or at least what it would look like if you had left 10 years before and not returned.
4) Relativity is Eienstein's 'great theory' that explains the interaction of matter and energy (or how they 'relate'; hence the name 'relativity').
E=m x (speed of light squared) or E=mc2 (2 is small superscript)
This equation describes the energy released when mass is converted to energy (as in the atom bomb); it also describes the vast amount of energy that is required to accelerate even a small mass to near the speed of light.

1) we cannot travel faster then speed of light because that is how fast energy goes and according to me if you wanna travel at speed of light then you should convert all pf your mass to energy because all light is a pack of energy which we call a photon.
2) Oxygen is on other planets but it is really small amount and also due to gravity oxygen didn't escape into space. i think you will now think that why doesn't jupiter have oxygen when it has gravity? Thats because it has other compound which are mixed up with oxygen.
3)yes we can see our future if we travel as fast we can. But the problem comes that the faster you travel the more friction there is. And if you see time travel is really happening. if you travel fast the time gets slower but it is so less that it is ignorable.
4) a wonderful theory of time. As other said that e=mc^2 is einstien theory but it only part of it. it is way more complicated then it sound. First of all there is
general relativity- how time goes when gravity is present. For example- if you pass the a black hole without sucked into it you will actually do time travel.
Special relativity- how time goes when there is no gravity present. Like is you travel fast enough you can do time travel.

1-we can not travel at the speed of light because our mass gets an inept value. but we can travel with small percentage of that speed
2-21% of the earth atmosphere is oxygen and this great amount of oxygen exist on the earth because of the earth's gravity and atmosphere pressure to get the oxygen on the surface
3-we can see our past by traveling more than the light speed
4- that was e=mc^2 which the mass can convert to the energy

Please see "Win S" answer. It is correct in every respect and is the same information I would have given to you.

I will add that travel much faster than 30,000 to 50,000 Miles Per Hour is technically not possible at this time. That is the fastest velocity that a man made object or device has been accelerated to so far. And, if you look closely that is not anywhere close to 186,000 Miles PER SECOND.

So your questions Number 1 and Number 3 must take that into consideration. Best bets for seeing into the future at this point are with the help of a palm reader or crystal ball.
