Something is Destroying The Galaxies in Our Universe – The Mysterious Killer !

Something is Destroying The GalaxiesAcross the Universe, as we speak (well, millions of years ago, but whatever) galaxies are being killed, Something is Destroying The Galaxies.

#1. Something is Destroying The Galaxies : The Mysterious Killer

Do you know that many Galaxies are dying in the universe. Few questions that amazes the scientists are:

  • What is killing the galaxies?
  • Why galaxies are dying?

Scientists and researchers are trying to find that monster since two decades but they didn’t understand what is the reason behind killing previously thriving galaxies. But recently, in 2015, Scientists got some clue and gives two big reason or theories that responsible for destroying the galaxies.

Something is Destroying The Galaxies

1. Strangulation

Researchers predict that some galaxies lose their hotness, there by the formation of new stars stopped and X-Ray spewing gas called Intracluster Medium. Then gas choked off slowly over time and galaxies become dead. This process is called Strangulation.

2. Ram Pressure Stripping

After doing new research, a great research paper published January 17, 2017 by a global team of researchers focused on approximately 11000 galaxies, Researchers come at this theory . This is the quick death of the galaxies called Ram Pressure Stripping.

In our universe 5% Normal Matter, 27% Dark Matter and 68% Dark Energy exist. This death is crime by Dark Matter. According to PhD candidate, Toby Brown, In this death, gas is violently torn away. A huge pressure applied on the galaxy and gas forced out. Toby Brown said:

During their lifetimes, galaxies can inhabit [dark matter] halos of different sizes, ranging from masses typical of our own Milky Way to halos thousands of times more massive.

As galaxies fall through these larger halos, the superheated intergalactic plasma between them removes their gas in a fast-acting process called ram-pressure stripping.

You can think of it like a giant cosmic broom that comes through and physically sweeps the gas from the galaxies.

Brown said removing the gas from galaxies leaves them unable to form new stars:

It dictates the life of the galaxy because the existing stars will cool off and grow old. If you remove the fuel for star formation then you effectively kill the galaxy and turn it into a dead object.

Galaxies are embedded by halos of the dark matter. When galaxy fall into the halos, Super heated Intergalactic Plasma quickly strip them of their star forming gas and galaxy become cold and lifeless.

#2. Something is Destroying The Galaxies: Conclusion

Researcher published their research paper in Journal Nature in 2015 that vast majority of dead galaxies happened via Strangulation. This death happened on that galaxies which 100 billion times heavier than sun and that is approximately 95% of the galaxies. But as mentioned above, in 2017, new research paper published in Royal Astronomical Society that showed Ram Pressure Stripping is more common death of galaxies. It can happened in both large and small galaxies.

#3. Something is Destroying The Galaxies: Key Notes

But you should not take this death seriously. Because if there Ram Pressure Stripping is happening in the galaxy, then it will be take more time. It can takes more than tens of millions of years. So, Enjoy your life on Milky Way. These monsters can not do anything with our galaxy.
