The theory of relativity formulated by Einstein in the first half of the 20 shows that the time is not absolute and depends on position and velocity of the viewer.
A person traveling at speeds close to light (something quite impossible today) travels at a slower time with respect to a person at rest who observes, this means that if we were on a trip in a spacecraft to 290,000 km / s orbiting the planet earth and we returned after an hour, the earth will last much longer (months or years), so in theory could become possible to travel to the future, but does not open possibilities for travel to the past, at least this law. The question is whether the technology include someday allow us to transport us to achieve near-light speeds, taking into account the enormous energy that would be required, and when I say big should have a word that meant 10000 times huge, this is the big question very difficult to answer today that seems impossible .. The film
films that talk about time travel are many, but without any scientific basis sustainable, although some such as "Back to the Future" is a good satire, instead of traveling in a spaceship at speeds close to the star light travels in a car eccentric and should only reach the speed of little over 100 km / to go ahead and also has the ability to travel to the past too.
made by Einstein's theory radically changed the way of understanding the universe, time and the laws of physics and earned him the recognition of the most important scientist of the 20th century and one of the largest in the history of humanity, at the height Newton's, but still not a hundred years will this revolutionary new way of seeing the world today while German scientist is a famous name, few really know that was what he discovered.
is it in the near or distant future that Einstein's theories have an application in our daily lives much more than at present and are understood by the majority?
