6 Most Frequently Asked Questions About Black Holes!
As mysterious as they appear, our knowledge about blackholes seem to be as dark as how they are pictured to be. That’s why we’re taking on the six most frequently asked questions about blackholes, in today’s episode! Subscribe for more videos:https://www.youtube.com/c/InsaneCuriosity?sub_confirmation=1? I think none of us here haven’t heard about blackholes, right? It’s basically a great conversation starter, and a plot device for a lot of science fiction. It’s like one of the great things that gets you interested in exploring the field of astronomy. And I wouldn’t blame you at all! I mean, it’s pretty easy to get amazed by how extreme, how bizarre, and how mysterious black holes are. If that doesn’t get you to be attracted to, let’s say science at the very least, I don’t know what will. Maybe some dinosaurs? But as majestic as they come, there’s really a lot that we don’t know about it. Even the scientists who study these kinds of objects still have a lot of questions, and each time they try to answer them, they end up with more questions. It’s a crazy Russian doll! That’s why today, why don’t we both get down to the bottom of it all. Let’s talk about the six most asked questions when people talk about black holes Number 6: How do we make blackholes? Okay, to set the pace, let’s get this going with something very basic and simple: the origin of a blackhole. If we’re going to talk about something, it’s one of the best places to start, right? In theory, anything can be turned into a blackhole. All you have to do is to compress the volume of the object into what’s called its Schwarzchild radius. Easy! But okay, let’s get real. We know that we don’t have that amount of force. Some of us here can barely open a can of pickles, let alone have the capacity to crush an object to an infinitesimally small size. So instead, let’s look at where there is an abundance of it: where else but space. Like it’s equally extreme cousin, the neutron star, blackholes can be thought to be some sort of stellar phoenixes: they arise from the ashes of another dea* star. Well, technically speaking, they didn’t arise out of nowhere. They’re the former nucleus of that other star. It’s like if a heart of some human comes out of its body and decided it wanted his own life. If you know Ricardio of Adventure Time, you’ll know what I’m talking about. Okay, that’s too much tangent. So let’s discuss how exactly an old star gives birth to a black hole. Stars undergo their own respective life cycles. It starts as a cloud of dust particles, to a young star, to a giant, then it goes to its inevitable deat*. So basically, a star fuses hydrogen most of its life, but once it runs out of hydrogen, it goes off script and begins fusing helium, and running out of that, it starts to fuse heavier elements instead. Now, you may think that’s nothing to be afraid of, but when you fuse heavier elements, you expect to generate more energy. This energy generated by fusion battles the gravity that’s been trying to crush the star, until the balance tips and gravity wins resulting in a massive, bright supernova. Whether or not it ends up as a blackhole normally depends on how massive the star was. On one hand, the core could collapse to a neutron star. On the other hand, if it's too massive, it becomes a blackhole. According to studies, the bare minimum mass range to determine whether a star will collapse to a blackhole or not is around 3 to 5 times Solar masses. Actually, it is guaranteed that if a star’s mass falls in that range, expect a black hole at the end of its life. Number 5: How can a black hole pull light? If you have studied quantum mechanics, one of the characteristics of light that you might have heard is how the particles of light, photons, are actually massless, by the common convention. And, the kind of force that black holes use is exactly gravity. From the basic definition of gravity, we know that for something to have this kind of force, it’s got to have mass. An object with extreme mass suc*s in a massless object? How exactly do black holes accomplish this? First, let’s explore a theory first brought by Einstein: general relativity. Specifically, the most important part of it which can help us understand how black holes work. Newton established gravity as some sort of non-contact force. It acts from one object to another event without contact. However, our hero Albert remediated this by explaining how gravity isn’t really an eerie force transmitted without contact, but is actually a distortion of spacetime by massive objects. Think of it this way, let’s say we have a trampoline, and that nobody is jumping up and down on it. Number 4: What’s the biggest and smallest a black hole can get?
