I am going to be talking about black holes, a lot! Because it is one of the most intriguing and perplexed ideas out there. Most people are confused about the mini black holes that the Large Hadron Collider is going to make… but these black holes are so microscopic that they will not interfere with anything. Or as people like to put it, it’s NOT going to swallow our earth! 

I’m bringing up black holes today because I was just reading in the science section of Yahoo! and it was talking about the black hole in our galaxy, the milky way. We know black holes exist, even though they are invisible, because scientists can measure the volicity and depth and all of a sudden energy gets crushed or sucked into this mysterious thing we call black holes. In the constellation of Sagittarius A* a super massive black hole exists in it, about 4 million times the mass of the sun, yikes! The mass of a black hole can take any positive value. What is so intriguing about Sagittarius A* is that it is the closest black hole, which is in the Milky Way. 

It is believed that there are 300 million black holes existing in the night sky. But what is beyond these black holes, we will never know in our lifetime, I doubt.

“How do they know these objects exist? They can infer the presence of a black hole from its interaction with a companion star. Many stars form in pairs or close groups. If one star in a pair becomes a black hole, it does not threaten its companion unless the companion wanders too close. Then the strong gravitational pull of the black hole can tear off matter from its companion in large streams.”  http://amazing-space.stsci.edu/resources/explorations/blackholes/lesson/whatisit/stellar.html

I’ll give brief details about two major black holes that are being observed in our universe:

The most known black hole is the Supermassive black holes. These contain possibly billions of solar masses and are thought to be in the center of all galaxies. 

Another type is the Stellar black hole. These ones are huge because they are the maximum mass of neutron stars. They are believed to be formed when a star collapses, and this is what happens when a star runs out of nuclear fuel.

I could go on for days with scientific lingo but I will save more talk about black holes for another day. They really are interesting and so peculiar.
