4 Very rare phenomena in the universe

Hello to all the companions of this great community of steemit, this time I will talk a little about some phenomena that are very great and is in our universe, keep reading to know a little more about these fantastic phenomena.

Gravitational waves

What we know by gravitational waves are some distortions that it has in the fabric of space-time, this is predicted by the theory of what we call Einstein's general gravity. Gravitational waves tend to travel at the speed of light, but these are very weak and scientists hope to be able to detect only those that are created during a colossal cosmic event, this is just like the fusion that black holes have, to be able to find them, expert scientists have launched projects that have the name LIGO and LISA.

Quasar

What we call Quasar, are the bright beacons that we tend to illuminate from the confines of our wonderful visible universe and that are supposed for some scientists a great reminder of how chaotic was the childhood of our impressive universe. These quasars can release more energy than many of the combined galaxies. The general consensus about nature is that they are monstrous black holes that are located in the heart of some galaxies that are very distant.

Vacuum Energy

What we call quantum physics manages to establish, contrary to appearances, the great empty space is a field that is bubbling with some particles that are subatomic, that tend to be created and then tend to be destroyed constantly. This fleeting particles give each cubic centimeter of space a certain energy that, according to general relativity, can produce an anti-gravitational force that makes our great space expand more and more, but nevertheless, the truth is that nobody really knows what is causing the accelerated expansion of our great universe.

Microwave Background Radiation

This Microwave Background radiation, is another great survivor of what we already know the Big Bang, could be detected for the first time as a faint noise that was heard coming from all parts of what we call the cosmos. currently it is believed that this is the biggest proof of the Big Bang theory: this is a noise of an explosion that created the universe. Although not all scientists agree with the above, what is more undeniable is that the background radiation does exist, and can be achieved to measure on Earth as a wave of photons, which has a temperature of 270 ° low zero, this is the biggest cold that can exist. This radiation floods every corner of our great observable universe for some thirteen thousand seven hundred million years. But nevertheless, the temperature has been lowering slowly, so it could come at a time when it is frozen and has no more energy to move.
