Boring as it may sound, time travel is actually quite exciting. It�s something that has fascinated scientists, physicists, and rocket scientists everywhere. I can�t deny that it fascinates me too. Why is it so hard to move in the fourth dimension? You can reach out right now and move through the first three. The fourth dimension, also known as time, requires much greater effort to traverse. It is, however, completely possible for matter with mass to travel through the fourth dimension.

Relativity and all that jazz can be confusing. Let�s break it down to simple terms. Basically, anything with an atomic mass would require an infinite amount of energy to send through the fourth dimension. You�re not going to find infinite energy just lying on the side of the road somewhere, so you need to find a way around it. Albert Einstein even said that it was not possible to do this. Warping spacetime sounds like an easy enough way around this dilemma. Yes, warping spacetime is the perfect way to send mass through the fourth dimension. The way this works is that, in theory, space and time are continuous forming one big spacetime fabric upon which all matter sits. By warping it around itself with an immense amount of gravity, you can, in essence, create a loop backwards. All that is needed then is a rocket ship to fly through the loop. It�s like drawing a line of chalk down a one way street and asking someone to drive over it twice without breaking the law. The only way to do it is to go around the block. Well, at least it�s the only way to do it in a normal car.

Wait! Warping spacetime might sound hard. That�s because it is. How about an easier way to travel through time? What about just warping space? Yeah! That�s even easier! Here�s where you need to buy the "Spacewarp" option in your car instead of buying a normal car like in the last scenario. Technically since space and time are continuous, you would be warping time also but it's easier to understand if I say you're just warping space. Anyway, now for the explanation: traveling through space, matter can not go faster than the speed of light. However, if we bend space, there is a way to go faster. Let�s say you�re in a rocket ship going slightly slower than the speed of light. Someone shines a flashlight next to you and you race it across the galaxy. You will obviously lose. What if you rapidly compress the space in front of you while at the same time rapidly expanding the space behind you? Now you have a bubble of normal space that you�re in. Everything comes at you a lot faster than it would normally because the space in front of you is so much smaller. Everything behind you is now moving very slow because there is so much more space. After you understand this, let�s have a rematch with that beam of light. Ready, set, go! Guess what? You, in theory, only have to be moving forward to beat the beam of light. The bubble you�re in does the rest. Depending on how fast you expand and contract space, you can move faster than light while only going a few miles an hour. How does this relate to time travel? Well, according to relativity, passing the speed of light is time travel. Let�s say you watch a football game on television and you happen to have a space compressing rocket ship but no VCR. You go inside to get a drink and miss a field goal that wins your team the game. How will you see it again if you didn�t record it? The answer is you climb in your rocket ship and fly miles away and past the light beams that came from your television during the field goal. You can now watch it in real time as the light beams reach you instead of seeing it later. Now look in the kitchen. You can see yourself too because you have passed the light rays that depict you.

I challenge anyone to argue my point and prove that time travel is not possible. As of now, we can�t do it. That�s because we don�t know where to get the type of energy to warp spacetime or space. It�s different than electricity or light. It�s something called negative energy density of exotic matter. What?! Yes, that�s what it�s called. As of now, we don�t have any, but maybe in the future we will. I never said it was possible to time travel now, I just said it was possible. This being said, I stand by my point and I am willing to debate fourth dimension traversal at any time.
