Black Holes: Even More

             By: Smaran

    Hello readers out there reading this article, sorry for not having an article last month. It happened due to technical issues. So here is another black holes article. Happy reading!

    So let’s talk about Fusion. It happens almost everywhere. In the core of the sun, and between black holes. It takes black holes with immense power and energy to shake the universe with gravitational waves. As stated from “Star S2 is around 15 times as massive as our sun. That’s big. But it’s nothing compared with the supermassive black hole at the center of the Milky Way, Sagittarius A, which is estimated to be some 4 million times more massive than our sun. The gravity it produces whips S2’s orbit to around 11 million miles per hour, which is about 200 times the speed the Earth orbits around the sun. S2 completes one orbit around the galaxy in around 16 Earth years. Recently, astronomers witnessed S2 passing by Sagittarius A* at a speed greater than its usual 15.5 million miles per hour. That’s more than 4,300 miles every second, or nearly 3 percent of the speed of light. This proved a good opportunity for scientists to test Einstein’s theory of gravity that claimed that light will stretch (red shift) when close to areas of high gravity, and it did!

    Science has also found the effects of two black holes colliding. Yes, such an event is possible. Two colliding black holes send ripples through the space-time fabric of the Universe in the form of gravitational waves. It is possible for two black holes to collide. Once they come so close that they cannot escape each other’s gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it. However, we do know that a black hole merger would produce tremendous energy and send massive ripples through the space-time fabric of the Universe. Nobody has witnessed a collision of black holes yet. However, there are many black holes in the Universe and it is not impossible to assume that they might collide. In fact, we know of galaxies in which two supermassive black holes move dangerously close to each other. Computer simulated models predict that these black holes will spiral toward each other until they eventually collide.The YouTube link for the sound of 2 black holes fusing together is here: .

By the way, there was a new image posted by NASA of as real life black hole, not one of those cool looking fake clip art pictures that you find out on the internet, here is a real black hole image posted by NASA next to a deblurred image yet the deblurring does nothing.     This is obviously not a perfectly accurate result, it is an approximation, but it seems to be a pretty good approximation. In fact, you can even see what appears to be gravitational lensing happening at the edges a lot more clearly now. Ignore the green boundary on the outer edges, that is simply banding being interpreted as light by the algo. The doughnut-shaped ring is ever clearer and the portions facing us, even brighter. Basically it is in line with Einstein’s Theory of general relativity (determined that the laws of physics are the same for all non-accelerating observers).
