The Universe

I made this because members are cerious. First of all their are 3 kinds of stars Red Yellow Blue. Red is low star when its at its end it just fades away.

 

The yellow medium star this star has a long lifespan. Also this is the same as our sun. When this sun dies it get huge and covers the entire solar system. Then it fades away to a gas cloud.

 

The blue star is the hottest and biggest star this star when it dies it gets huge like the medium but after that it blows up. Sometimes a little gravity thing forms in the middle and collects gravity then it creates a black hole.

Blue stars actually implode so quickly, they collapse into the black hole phenomena. Smaller suns can do this as well, but the conditions have to be right.

Its probably once in a blue moon a low star would do that.

Adding a bit more: Yellow Dwarfs and Red Dwarfs are most common throughout the universe, our sun being a Yellow dwarf.

You've then got Red Giants, stars which have expanded to be 100x their original size, the Blue Giants, which burn up Helium. Supergiants, which are the largest known star, can get as big as our solar system, although these are rare. When they die they become black holes.

White dwarfs are small stars, about the size of Earth, but are much, much heavier. Eventually they lose heat and become a Black dwarf. Brown Dwarfs are stars that cannot have Nuclear Fusion occur at the core, and so are not very luminous. Neutron stars are very small, super dense stars and is mainly protons, with a diameter of 5-10 miles and density of roughly 10 ¹⁵ gm/cm³.

To add, supergiants arent the biggest, hyper giants are, thought they are incredibly rare in our galaxy and other galaxies too.

Yeah but, nobody really cares about stars here, so they won't know that. lawl

Except us science boys! Yays!

Yea lol yay

What happens when you get 2 black holes?

 

There is an answer to this question...

What do you mean? Like when they meet, cause they would be consumed into ine larger black hole, but eventually die off due to hawkings radiation.

What do you mean? Like when they meet, cause they would be consumed into ine larger black hole, but eventually die off due to hawkings radiation.

The only black holes that die off due to Hawking's radiation are those that lose more mass than they gain. Also, Hawking's radiation is just a theory, so it may not even be true.

 

Black holes that appear in an area where they can absorb a lot of mass tend to turn into something called a "Super-Massive Black Hole". These black holes are theorized to be responsible for certain galaxies and their orbits. For instance, there is actually a smaller SMBH in the very center of our galaxy. Smaller being unbelievably large, yet not as large as others that have been confirmed.

 

It's also worth noting (however a sort of no brainer) that the more a black hole "consumes" the larger it's event horizon expands. The ratio of expansion/consumption is different for every black hole, however seems to be based on the size of the black hole.

 

Another thing you should know about black holes is that they can compact particles. Imagine getting a rubber ball and using a vice to squish it. The sheer gravitational pull of the black hole and the amount of mass the black hole has "consumed" already causes a similar effect on particles, which are the smallest confirmed source of matter so far.
