crazy Below this square there is a "play", not the square. The "play" is not seen but if you notice the cursor changes to a hand, you clickea the square below and voila, it starts only. It's a way to travel from tiny particles, into a car, a house, a mountain in order to reach the top out of the human eye. Navigate to the navigation bar that accompanies the tiny square.
Have a good trip.
Under the new theory of universes that continue, the universe does not die, but will repeat. Or maybe it will be a cold, dark universe, as galaxies and stars are separated from each other and their light and heat is lost in the darkness, forever expanding and cooling down to a state of absolute cold, where molecules have no energy to do the slightest movement? Or is a universe, after expanding, will reach a time when it will begin to collapse on itself and then the problem is reversed? Lately there are other theories that speak of a Big Rip (Great Ripping), 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 fabric is stretched to tear.
Are there alternate universes or multiple?
One theory posits that there might be an alternative universe of dark matter while the latter, but we could not achieve. The best way to imagine is to think of a double glass window with a fly in the middle. The fly can not cross from one side the other, just as we can not cross from one universe to another. These two worlds would be attracted to each other by gravity and eventually collide. In doing so, create a big bang. 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, 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 dark matter?
is a hypothetical form of matter that has more mass than visible matter, but unlike the latter does not interact with the electromagnetic force. Scientists infer its presence because it has gravitational effects on visible matter. For example, the rotation speeds of galaxies, orbital velocities of galaxies within clusters and the distribution of gas temperatures of galaxies suggest that there must be something there something else. There is more material in clusters of galaxies from which we might expect of galaxies and hot gas we can see. Apparently, 30% of the universe is composed of dark matter. Discover its nature is one of the most important goals of modern astronomy.

What are the components of the universe?
stars, asteroids, planets, cosmic dust, the elusive neutrinos, helium, hydrogen and everything we see around us make up a fraction of what the universe. The remaining 95% is occupied by the strange dark matter and even more incomprehensible dark energy.
What is dark energy?
This is the Mecca and perhaps the biggest mystery in cosmology today. Dark energy is a mysterious presence that offers the best explanation so far about why the universe is expanding at an accelerated rate. In the current model of cosmology dark energy makes up 70% of the total mass-energy of the universe. There are two models according to which dark energy pervades the universe or unevenly or change of energy density at certain times / places. Scientists agree that it is sparsely
(10-29 grams per cubic centimeter) and does not interact with the fundamental forces except gravity.
how many galaxies there are and how they formed?
There are about 100 billion galaxies. However, the detailed process of its formation is another open questions in astronomy. There are several theories under which small structures such as globular clusters were joining each other under the gravitational forces. In other models, several proto-formed in a large simultaneous collapse that could last a hundred million years.

What happens when two galaxies collide?
is very common for galaxies collide, and interact with each other. In fact, it is believed that collisions and connections between galaxies are one of the main processes in its evolution. Most galaxies have interacted since they formed. And the interesting thing is that in such collisions no collisions between stars. The reason is that the size of stars is very small compared to the distance between them. Instead, the gas and dust they interact so that even come to change the shape of the galaxy. The friction between the gas and galaxies colliding shock waves which can in turn initiate the formation of stars in a given region of the galaxy.
What is a white hole?
The equations of general relativity have an interesting mathematical property: they are symmetric in time. That means you can take any solution to the equations and imagine that time flows in reverse instead of forward, and you get another set of solutions to equations, equally valid. Applying this rule to the mathematical solution describing black holes, you get a white hole. Since a black hole is a region of space from which nothing can escape, the opposite version is a region of space into which it can not fall nothing. In fact, as a black hole can only swallow things, a white hole can only spit. White holes are a perfectly valid mathematical solution to the equations of general relativity. But that does not mean that one actually exists in nature.
Is there a Higgs boson and has the secrets of the universe?
For over two decades, scientists have been looking for one of the most elusive things in the universe, the Higgs boson, this particle gives mass to everything in the cosmos. It is a particle theorized but never seen. The Higgs boson is famous for being the only particle predicted by the Standard Model of physics that remains undetected. In theory, all other particles in the universe get their mass by interacting with the field created by the Higgs bosons. If the Higgs is discovered, the standard model can announce that it is the theory that unifies everything except gravity.
Is there extraterrestrial life?
So far no space probe or telescope has found specific traces of life as we know it on Earth. The debate over extraterrestrial life is divided between those who think that life on Earth is extremely complex, making it unlikely that there is something like us in another planet, and those who point out that the processes and chemicals involved in land creatures are very common in whole universe, and the only thing to look for are the right conditions. For the latter, it is quite likely that there is life similar to ours in other worlds, search for extrasolar planets which we are engaged.
Does life came to Earth on an asteroid? To
astrobiologists studying the possibility of life on other worlds, interplanetary travel need not be the privilege of comets, cosmic dust and space probes with or without people inside. It is not unreasonable, they say, suggests that there are or have been other cosmonauts out there: Cowboys who travel on the backs of asteroids, stowaways who hide in the folds of a space suit, and even unhappy creatures displaced from their brutal collision worlds. All these tiny life forms could have bounced between a planet and another, carried to and fro like leaves in the wind on the cosmic brutal weather. View, life on Earth could well come from Mars ... or vice versa. Or perhaps the moon Europa, or why not Titan. Or maybe the spore with the spark of life came from the other side of the Oort cloud of asteroids. This is the theory of Panspermia.
