Scientists explain space collisions with Planets, black holes, and stars

The universe that we know and live in has been existing for more than 14 Billion years which is a very good timeline for the gravity in order to pull the matter into clusters, collapsed objects, and clumps. With time, the universe started seeing stars, planets, galaxies, and many more structures all paired together with the backdrop for an ever-expanding universe.

However, things aren’t as simple given the fact that the universe consists of trillions of space objects that are moving within the timescales of hundreds and billions of the years of existence of the universe. Anything that happens in the space such as any collision or any merger tends to change the thing that we are left with for the future.

Different types of collisions tend to leave a different kind of mark on the surrounding environment such as a planet with planet collisions. In our inner part of the Solar System, the scientists believed that there was a planet that was Mars-sized, which collided with the young new, forming Earth which gave birth to a cloud of small and big debris which merged to create the Moon near Earth that we know now. This impact hypothesis was thoroughly validated with a number of evidence which included lunar samples that were brought to Earth during Apollo missions.

Brown dwarf tends to be big gas giants that are way bigger than Jupiter to scale in numbers, they are more than 12 times bigger than Jupiter. However, they tend to have deuterium fusion in their center with no hydrogen fusion which is also known as a false star. However, the collision of two dwarf stars leads to a merger of false stars that bring out an actual star with critical threshold 0.075.

In cases of collision between two stars, the merger leads to creation of a massive star that comes from two red stars creating the blue star with solar mass of 1.5 that is combined with red stars of solar masses such as 0.7 and 0.8. The blue stragglers tend to exist in dense environments with globular clusters that demonstrate the presence of gravitational mergers.

When neutron stars tend to merge together for creation of single one, they create three creational instances. The first instance leads to creation of a rather giant neutron star with solar masses below 2.5. In another instance, the neutron star tends to spin or collapse into the black hole with the total solar mass that boiled down to 2.75. Lastly, the impact leads to a collapse directly into the black hole if the solar mass goes beyond 2.75.
