The universe and his misterys.

What is the future of the univers?

               

According to the new theory of universes that continue, the world will not die but will repeat. Or maybe it will be a cold, dark universe, as galaxies and stars are separated from each other and its light and heat are lost in darkness forever expanding and cooling down to a state of absolute cold, where molecules have no energy to do any movement? Or is a universe that, after expanding, reach a point where you begin to collapse in on itself and then the problem will be the reverse? Lately there are other theories that talk about a Big Rip, in which the rate of expansion would be so tremendous that groups of galaxies, stars, dark energy and everything else would become a kind of cloth that is stretched to tearing.

Are there alternative universes or multiple?

One theory posits that there might be an alternative universe of dark matter while this, but we could not reach. The best way to imagine it is to think of a double glazed window with a fly in the middle. The fly can not cross from one side to the other, as we can not cross from one universe to another. These two universes would be drawn to each other by the force of gravity and eventually collide. Doing so would create a huge explosion. This would imply that things are happening right now that will help create another universe in the future.

On the other hand, there are several hypotheses of multiple universes in quantum physics and cosmology, in which the physical constants and the nature of the universe are different. For example, the "bubble universe" is an infinite series of open universes with different constants.

What is the black matter?

It is a hypothetical form of matter that has more mass than the visible matter, but unlike the latter does not interact with the electromagnetic force. Scientists infer their presence because gravitational effects on visible matter. For example, the rotational speeds of galaxies, orbital velocities of galaxies in clusters and the distribution of gas temperatures of galaxies suggest that there has to be something more. There is more material in clusters of galaxies than we could expect from the galaxies and hot gas we can see. Apparently, 30% of the universe is composed of dark matter. Discover your nature is one of the most important goals of modern astronomy.
