Ever wondered what Black Holes are?

Hello Astronomy Enthusiasts,
Like I said in my last blog post that I am going to write about what I know about things in astronomy. Today, I am going to tell you about Black Holes, an interesting topic which I love and hope you will too.

What are Black Holes?

Basically, Black Holes are things that bend space-time extremely and create an area that nothing escapes. Like not even light! The last spot you can be as close to the black hole and not be caught is called the event horizon. It's kind of like a border to the black hole. To understand what it is, you need to know what space-time is. Since objects with gravity bend space-time, black holes bend space-time too. not like the sun or the earth. Million times of our sun. Since the black holes are really huge in gravity the holes bend space-time in an extreme order and it's like putting a bowling ball on a soft, thin sheet of fabric. because of this anything that goes in can't come out because anything is not strong enough to escape the hole. The last spot or place you can be as close as you can to the black hole is called the event horizon and it is sort of like a border to the black hole. These black holes are really cool and they can even make gravitational waves when 2 black holes collide.

What is Space-Time?

Space-time is a really cool concept that is very helpful and important to learn about black holes. So, as I said before,  space-time is like a never-ending fabric. In real life, there is 3 dimension: length, whit, and height, but space-time is 4 dimension: length, with, height, and time. Space-time is not only in space but everywhere. space-time is the reason there is gravity. Gravity is how much an object bends space-time. everything bends space-time. Computers, apples, earth, moon, and even water! It literally bends everything that not only has mass but even energy. If you want to visualize this, you can do a little experiment! All you need for this is fabric, a heavy object (doesn't have to be too heavy), and an object lighter than in the first object. Now, after you gathered all the materials, hold the fabric horizontally, and put the heavy object in the middle. As you can see, the heavy object bends the fabric which is space-time. then, put the lighter object close to the heavy object. What happened? the lighter object went towards the heavier object. That is Gravity!!! The attraction of lighter objects towards lighter objects!

What is Gravity?

Like I said in the last paragraph, gravity is the thing that the space-time is blended. Also like I said before, everything bends space-time. The reason you don't see 2 objects attracting towards each other is that in the real world, everyday objects bend space-time very slightly. The earth is revolving around the sun because of the curve the sun creates a curve in space-time because of its weight. Even the earth has a moon because of the curve it creates in space-time. these objects revolve around because, when you put an object next to a bigger object, it doesn't go straight to the object, it goes around the object to the bigger object. Even light has gravity because it has energy! So, if a light photon passes through a planet, it actually pulls the planet towards the light photon. According to my, that's pretty cool. So, that's basically it for this week's blog post on black holes check out my next blog post on why we can't take all the waste and crash it into the sun and I will see you there!

Thanks for reading and have a great day!
