Some very rare things that exist in the universe

Hello to all this great steemit community, this time I will talk about some things that exist in the wonderful space and tend to make it very rare for us. continue reading to learn more about these rare things that exist in our spectacular space.

Mini Black Holes

If the new and very radical theory of what we call gravity or better known as (world of branes) is very correct, then we must also believe that our great solar system is totally plagued by many tiny black holes, each one has a size of an atomic nucleus Unlike their larger relatives, those we know as mini-black holes are remnants of the big-bang and these tend to affect spacetime in a different way because of their close association with a fifth dimension.

Galactic cannibalism

Like us living beings on our planet Earth, galaxies can get to "eat" each other along this as time passes. Our neighboring galaxy, Andromeda, is currently getting a snack from one of its satellites. Inside there are many star clusters, these clusters are comic remains of many other foods that this galaxy has been delighted. It can be estimated that the Milky Way and the Andromeda galaxy will end up colliding with this can happen as in 3,000 million years.

Neutrinos

What we call neutrinos are very elementary particles, virtually devoid of mass and electrically neutral, these can pass through our body is can even pass through many kilometers of lead, this without any difficulty. These phantom particles tend to occur inside the healthy and very healthy stars, and also in the explosions that there are of stars that are dying giants, but better known as supernovas, they have neutrino detectors that are specialized like IceCube, this is finds buried 2,500 meters below Antarctica.

Cosmic background radiation

This type of radiation is composed of some primordial remains that are left by what we already know is the Big Bang that gave rise to the universe. It was detected for the first time as for the decade of the 60s in the form of sound as radio coming from all parts of space. It can be considered that it is one of the fewest evidences and the strongest this in favor of the Big Bang theory, some recent precise measurements that were made by the project known by its acronym WMAP could determine the temperature of this radiation and the temperature was between -270º Celsius.
