Travel back in time, a crazy idea, but impossible?
This is the title of a news story that has impacted me a lot. What person we has not wanted to travel in the future or in the past? A crazy idea, half in the field of fantasy, half in the realm of science fiction. Travel back in time, would give us special abilities: to know the past and the future, to know how to bet on poker and perform feats.
The first difficulty is the nature of the time, the sea in which navegariamos, so incomprehensible, such as water, escapes us before you can grab it.
Einstein who joined at the same time as the fourth coordinate (dimension) of the geometry of space-time continuum where we live. Where light plays a fundamental role. In 1915 Einstein formulated the theory of relativity in which the speed of light is invariant in all systems of reference and which constitutes the upper limit imposed by the nature at all speeds (in particular, an object traveling at the speed of light, not having the time). In addition, Einstein found that light is made up by those who conduct themselves as pure: the photons. Surprisingly the light sometimes behaved like a wave and as a particle.The same Albert Einstein said that "the past and the future are not only an illusion, albeit very convincing"
On the other hand, the theory of black holes, initiated by Einstein, propalada By Stephen Hawkins, from his wheelchair, and studied by hundreds of astronomers around the world, shows us how certain black holes, forming worm holes in space, would allow the light to take shortest paths and arrive faster to the future
In a strict sense, often we travel back in time mentally: we are always planning for the future. This activity not only is crucial in our future, but has been crucial in our future as a species of animal.

Comment: The news as well I find interesting because how to speak of something unknown and exciting, a question that all human beings we have thought and we have tried to explain a knowledge of the time (today). Time travel is something that every person has wanted to, you could handle everything you could redo actions of the past to change or the future or just to improve the future, either making money or finding happiness. Although I agree with the words of Einstein saying that everything is an almost perfect perception that is not reality
