Introduction:
If you think about it, you've probably wondered how long light travels in a certain amount of time. It doesn't take that long! It takes just 1 second (1/1000 of a second) for light to travel from the sun to your eye. So why do scientists ask themselves this question when they try to figure out how long it would take humans to reach light speed?
The accelerating expansion of the universe means that if you want to travel slower than light speed, you're going to need a warp drive. So how fast is light? Well, that's where the question begins.
Can humans survive light speed?
The question of whether or not humans can survive light speed is a controversial topic. Some believe that it is impossible to survive light speed, while others believe that it might be possible. However, the truth is that humans can't survive light speed because they are unable to handle the heat and pressure of traveling at such speeds.
The human body cannot withstand the pressure and temperatures that would be produced by traveling at light speed. In order to travel at light speed, the Earth would have to shrink down to around one-tenth its current size and its atmosphere would have to be compressed into a very thin layer of gas around it. The amount of energy required for this process would be too much for our universe currently to handle. So, even if we could build some sort of spaceship capable of traveling at light speed, there's no way we could ever get inside it!
It's important for people who think we can survive light speed to know that there are other ways we could get there without having to shrink down so much or compress our atmosphere into thin air. There are other ways out there besides shrinking our planet into space and then making ourselves go faster than any object has ever gone before! We could just go faster and faster until we reach something like 20% time.
The light speed limit is a limitation on how fast information can be sent through space. For example, if you are sending a message from Earth to Mars, the time required for this message to reach its destination would be limited by the speed of light.
The faster a message travels, the shorter its transmission time will be and therefore the greater the number of messages that can be sent simultaneously.
If we could send messages at speeds beyond light speed, then we could send messages between any two points in space (such as Earth and Mars). If someone were to send us a message using such technology, it would take them months or even years to reach us.
Conclusion:
As long as black holes are included in the equation, light speed may be too fast for anything to truly survive. On the other hand, if you disregard that theory, there is a possibility that humans could eventually evolve or create altogether new ways of traveling and living – perhaps even taking up residence in outer space. As long as black holes are excluded from the picture, space travel remains possible and is most certainly not impossible – just difficult and expensive.
Forgive my lack of citations for this article — I was too busy to cite, and have a class this afternoon. Anyway, Faster-than-Light travel is, in my opinion, the most intriguing topic out of all those discussed on the Sci-Fi Approved site, and it's been debated at least since 1973 when the topic was first discussed in Scientific American. And while it may not be 100% true that FTL travel is possible because C. Clarke has made a prediction that we shall never reach it due to "bad luck," I feel it will be possible with advanced technology.
