The human race has always wanted to take hold and have power of what lies ahead in the future, or possibly to foresee what will occur. That is the reason why astrology is so well known. Science claims that occasions on Earth are identified with movements of the planets over the sky. This is a logically testable speculation, or would be if scientists/researchers put their necks out and made unmistakable expectations that could be tried.
Black holes are one of the universe beautiful mystery that has astounded astronomers and scientists ever since the past decades it has discovered. One of the most talked about and popular topics/subjects in science theories is that, black holes as being one of the greatest conundrum of the nerdy science-y world. Even right now, today, the concept of the dark dense ball of matter that has an intense gravity that even light can escape from its power is really implausible.
Now, the thing that mesmerized me on discussing about black holes is because of how they work, or more profoundly, how physics works on them. It’s simply questionable & mysterious and it makes me curious to explore and discover beyond the dark matter itself.
There is a point of space in a black hole that is so dense that they create/make a deep gravitational pull/sink. And beyond point on the dark matter, the gravitational pull is so dense and strong that light can’t escape the powerful tug of a black hole’s gravity. And anything that ventures too close be it star, a small or big planet, or spacecraft will be stretched and compressed like a rubber band in a theoretical process which scientist commonly refer as spaghettification.
Now, how about putting ourselves to an escapade and visualize we’re gonna travel into the enigma of black holes like a tour. How would it feel like if our rocket ship were to set forth too near to the black holes which is skulking at the middle point of the Milky Way? According to author Neil deGrasse Tyson, on his book entitled Death by Black Holes, size eventually does matter when it comes towards to black holes, though the probability of your survival during the encounter won’t be resulting to any good.
The first regulation for anyone that’s going to handle with black holes are, of course, don’t get near to it or you’ll suffer the aftermath. But if you say you will, then you’re in for quite a trip, a dangerous one-way trip to the unknown because there is no coming back once you fall into that mysterious black matter.
A black hole isn’t actually a hole. It’s eventually, it’s the opposite. Black holes are eventually a place in space that is containing a lot of stuff packed very closely together that it has become a sphere-like ball of matter. It has gathered so much mass and energy and hereby created an undeniable strong dense gravity that nothing will ever escape from it, not even a ray of light.
And if light cannot escape a black hole, then neither can you nor anything in this universe.
So, anyway, let’s go back in putting ourselves in the adventure but this time, what happens if us, a human, goes inside a black hole? What could this mass of anti-matter could possibly do to our fragile body? Now, based on my own understanding after I had read Mr. Tyson’s book, if you were made of rubber then got sucked into the vortex of dark matter then you would just stretch in response. That’d be cool to just stretch but unfortunately humans are composed of other materials such as bones and muscles and organs. There’s a 100% our body would stay whole until the instant the tidal force exceeded your body’s molecular bonds. To be precise, we will be squeezed to death.
After the gore moment, your body snaps into two segments, breaking apart at your midsection. Upon falling further, the difference in gravity continues to grow, and each of your two body segments snaps into two segments. Shortly thereafter, those segments each snap into two segments of their own, and so forth, and so forth, bifurcating your body into an ever-increasing number of part until nothing is left from you. Sickening yet Mr. Tyson’s word are indeed logical.
On additional note, based on my recent study, I had also discovered that a close neighbour of our galaxy, the Century A is a giant elliptical galaxy which is estimated to be 10 t0 13 million light-years away from the Milky Way. Believed to be powered by a supermassive black hole at its center which scientists hypothesized to be the result of a cosmic collision between an elliptical and a spiral galaxy.
That fact just proves that the collision had a really huge amount of energy released that it eventually created a galaxy. But the black hole still have a lot to be explored on and discovers that should be found.
Now, what are black holes made of? What’s inside or beyond them that makes them dangerous or peculiar? Sounds mysterious, right?
The simple answer is that no one even knows. A black hole is defined as a region of space time from which extremely strong gravity prevents anything, including light, from escaping.
We know that matter falling into black holes is no different from the matter which can be found lurking around the rest of the Universe. However, the closer we get to the centre of a black hole, the faster our understanding of physics breaks down. Thanks to General Relativity, we think we understand what happens in this extreme gravity and with the help of Quantum Mechanics, we can make an intelligent estimate as to what happens at smaller, microscopic scales. But if the two theories are combined – like they would be at the centre of a black hole – they break down, leaving us with no idea as to what’s going on!
To get around the problem, astrophysicists need a theory of gravity that is compatible with Quantum Mechanics that might just describe the physics inside a black hole. At the moment though, no such model exists but physicists are working on it.
Anyways, going back to my main topic, still got questions in my head that wants to be answered. Though, how are black holes initially made or created? Technically, I had heard from our first grading discussion on Earth and Science subject that black holes came from dying stars. Though, as well, what makes them so dangerous? Is it because of their expansion rate and density? Or something else? And what eventually requires to create one?
The largest black holes are usually referred as or called ‘supermassive.’ These kind of black holes consists of masses that are more calculated to be up or more than a million stars together. Astronomologists had discovered evidences that every large galaxies in the universe eventually contains a supermassive black hole at its middle point. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths! Amazing and intriguing, ain’t it?
A black hole is a place in space where gravity pulls so much that even light cannot get out sounds super dangerous. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Also, black holes can’t be visible in our naked eyes (obviously). Because no light can get out, people can’t see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.
When a black hole and a star are close together, high-energy light is made. This kind of light can not be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.
Black holes do not go around in space eating stars, moons and planets. Earth will not be sucked up into the anti-matter hence there is no black hole that is close enough to the solar system for Earth to be absorbed/disappeared to. Also, on additional note, the sun will never turn or become into a black hole. It’s simply because that the sun is not a big enough or the sun’s energy is not strong enough to create a black hole.
NASA have been using various satellites and high-lensed telescope that is wandering into the wonder of deep space to learn and grasp more knowledge about a black hole. These paraphernalia helps scientists and astronomologists answer inquires about the unknown of the galaxy, it always fascinates me that sciences always advances it’s technology. Going back, even if a black hole has the same multitude/mass and density as the sun and it was to replace the place in the location the Sun, our Earth would not be sucked in. Hence, the black hole will eventually still conatin the same gravitational pull as the sun resulting to the same as usual. How? Well, Earth and the other planets in this universe would eventually still orbit the black hole as they’re orbitting the Sun right now.
