How do we control faster than the speed of light travel?

Apparently, we can travel faster than the speed of light they say. Its like the universe expanding faster than the speed of light. The analogy I heard is ants on the surface of a balloon, they don't move but the baloon expands and they become farther apart (traveling at the balloon expansion speed which represents the universe expanding). I am not sure if I understand all this. Has someone got a scientific explanation in simple words for a non-scientist? Thanks.How do we control faster than the speed of light travel?
Do not mix up the idea that space is expanding in the universe with the idea of moving matter faster than light. Any matter can not get to light speed, you will get stronger distortions of space, time, and mass at you try to reach it so that it makes that impossible.





There are ideas on how to ';appear'; to go faster than light. One is a ';warp drive';, the idea is to compress space-time itself in front of a space craft. This warping of space-time would make it appear to an outside observer that the space craft is traveling faster than it is. Including looking like its going faster than light, but since we are distorting the space-time fabric and not actually moving that fast it is permitted by the laws of physics as we understand them at this time.





It is the opposite of the actual cause of red shift for galaxies. The universe is not so much expanding into anything, but it is creating more space/time inside itself. Take a piece of graph paper and draw new lines between the current lines horizontally and vertically. Each time this is done, the paper doubles the squares in it, but never changes its actual physical size. This expansion of space causes the light moving across space to be stretched as its expanding causing the red shift and even the fact that some galaxies look like they are moving away faster than light.

You cannot travel faster than the speed of light. Einsteins equation


E=mc2 shows that in order to even just travel at the speed of light would take an infinite amount of energy, more energy than there is in the entire Universe! On the hypothetical tachyon can travel faster than the speed of light because they have no mass. Mass is the limiting factor. The Universe cannot expand faster than the speed of light either. Same reasons as above. The expansion of the Universe may approach the speed of light but could never attain it.
Local areas of space are not expanding. At least not significantly. This isn't an effect you could control anyway.





Space itself is expanding. It's expanding at an even rate, so a galaxy twice as far away as another from us is receding twice as fast away.
we can't travel at the speed of light, universal expansion means that every gravity well is moving away from every other gravity well at a constant speed, so its not as if we can use this expansion speed to move between stars faster.
