Blogpost 5: Black Holes

Can you imagine what could happen if you got suck by a black hole? Scientists say that every part of energy can be sucked up, I mean everything, atoms, matter, yourself, and even light and sound. It's so massive and powerful that no one would be able to escape once you've been caught by it. Can you also imagine what's in there? Like, what would you see when your're exactly inside a black hole? I guess no one could know, because I think it's very impossible for us to get inside then go out. Black holes also have gravitational around it's spot that lures everything that'll be eaten by it.

Scientists told us that black holes are the death of the stars, but not exactly just a star. Only massive ones, for example, our sun is not that massive enough to become a black hole. So it means it needs a bigger one. Imagine that the black holes are far bigger than the sun. How terrifying. But did you actually know that there is a black hole that is only 26,000 light years away from us? I've read an article entitled,  It's Snack Time In The Cosmos by Ron Cowen from nytimes.com. It is stated there that we might have the chance to see a black hole consumes. A black hole called the "Sagittarrius A." Of course from a big telescope because it's not seen by the naked eye. A theoretical astrophysicist at Harvard named Avi Loeb even said that "This is a rare oppurtunity to witness spoon-feeding of a black hole," and even asked, "will the gas reach the black hole, and if so, how quickly?" then he even theoretically stated that, "will the black hole throw up or spit the gas out in the form of an outflow or a jet?" The one that will soon be sucked by the black hole is a gas cloud. The cloud is massive, it's even three times bigger than the Earth. But it's still no match for Sagittarius A. The black hole will soon devour every part of that gas cloud. It will use its gravitational forces around him to set the direction of the gas cloud to the center. But they also said that if the black hole has eaten too much of its gas, it's process of eating could take years for it to finish. Then, a firework could be seen. The firework they'd talk about is a metaphor for a radiation explosion through the cosmos.

I can imagine the power of the black hole by just seeing the pictures. I think that if you were to go there, you would really feel the massive force of its gravity pulling you. We still won't know what could be the effect of the radiation explosion of those events because it's the first time for us to happen. Also, according to some scientists, when the black hole sucks you, you would stretch very long like you're a bubble gum. Imagine those things, it's like defying the laws of science.

There is also an article I've read entitled, How Do Black Holes Form? written by Fraiser Cain from universetoday.com. It is stated here that back then black holes were just considered as abstracts. They still haven't concluded that they exist. But in 1931 an astronomer named Subrahmanyan Chandasekar calculated and studied stars, then eventually came up with the conclusion that black holes can be form by a stars big mass. They also said that inside a black hole, there are millions of tonnes of hydrogen that are changing to helium. After that, it releases gamma radiation. For them, this process is too "exothermic," meaning it's exaggerating its energy extraction. Then soon, they said that the helium will switch to carbon then becomes oxygen. But it also balance its gravitational forces to make it at least stable. After that, well, it's more likely to a black hole now. A star that was so bright and shiny became a dark and evil existence to the most dangerous and terrifying objects in our universe. Like they said, you would need a velocity even faster than light to escape these things, or maybe, speed of light is not enough? Who knows? But even through the research and findings that a black hole is a bad object, Fraser Cain the publisher of universe today still stated that: 

"Black holes are the most exotic and awe inspiring objects in the Universe." 

We can't really know much of these things because we need  to study these kind of objects in a very accurate way, like, we need to study them very clear and very actively to know what's really in there. But I guess we can't, because it's obviously dangerous for us to even get near them.

So what might happen when you're in a black hole? Do you even want to test it for yourself? From this study I think I could say I hate black holes. They're too scary for them to even exist. Why were they even created? Do they have a purpose? I don't think so, I can say they were the evil creatures that have been formed on the universe.
