This curious effect is related (although it may not be obvious) to the fact that nothing with mass (like a rocket or astronaut) can be accelerated to the speed of light or beyond. Heck, enough time may have passed for us to have evolved second heads if the astronauts travel at a high enough speeds and far enough distances. May well have experienced thousands of years (or more). When the astronauts get back, human society In other words, if the trip to a distant star and back takes a few years for the astronaut, many years have passed on Earth. Travel close to the speed of light on the ship and then come back to Earth, the time which passes on the ship is much less than that which hasĮlapsed on Earth. Here also lies the crux of another problem, namely, time dilation. Of all, it would require an awful lot of fuel to accelerate the rocket to high velocities so that the trip could take place in a reasonableĪmount of time for the astronaut.
Just hop on a rocket and go, right? Well, no, not really. The idea of traveling to distant stars and galaxies is, to many, quite appealing. It requires some mathematical sophistication as well as some knowledge of General Relativity and Quantum Field Theory. The second part is slightly more rigorous and mathematical. Heavily on analogies with well known systems and asks the reader toīelieve some statements without proof.
