Learning about black holes• Black holes thought to exist at the center

of most galaxies.• Black holes can’t be observed.• Black holes are so dark, that light can get

to it but no through it .• The first black hole was discovered in

1916 by a man named Karl Schwazschild.• Black holes suck up everything in their

path.

 Creation of  black holes

Before a black hole is a black hole it's a supernova.And before that it was a red supergiant.Even before that it                                               was a massive star.First its a stellar                                               nebula• creation of a                                                        

          black hole

 

Black holes are at least 10 to 15 times larger than the sun.Black holes are one of many parts of the end of a stars life.A black hole can grow to have the mass of 18 billion suns.

One of the largest black holes

Sizes of black holes

Sizes of black holesThe smallest black hole weighs about 4 times the mass of our sun.(3.8)

The smallest black hole is about 15 miles or 25 kilometer, in diameter.

The black hole is part                                                                 of the binary star system

Sizes of black holes

 One of the names of a black holes is

X-1   ( X-1   l )                 V

Milky Way Galaxy

There are billion, trillion of stars and black holes can be formed by any of them. Its very difficult  to tell how many black holes can be in a universe.  Astronomiers beleve that there is one black hole at center of each galaxy.

 ( Some of the stars of the    Milky Way galaxy )

Milky Way Galaxy

There may be hundreds of black holes roaming the Milky Way Galaxy.                                               

               

Most galaxies if not, all are believed to have supermassive  black holes at the center of their

galaxies.

Black hole are a hole in space time.

Blacks hole maybe cold alter because they deal with  time.

            MYTHS

One myth about black holes,is that the sun will become a black hole. • This is False because it is

too small to become a black hole.When the sun burns out it will become a white dwarf  

• Another myth is, when falling into a black hole, I can see the fate of Universe flash before me!

This is False, but you might see your life flash before you.

A huge myth is If I go into a black hole, I come out of a white hole!
