| Infinity: The symbol of Infinity. |
Some people think infinity is possible. I, of course, agree with them, but not quite in the same way. Because, you see, I only agree with them in numerical terms. Numbers continue on forever, no beginning, no end. However, that is the only way infinity is possible. Lets take, for example, a black hole. Scientists say that it has infinite gravity, infinite mass, and an infinitely small singularity. But I disagree. None are infinite.
First, the gravity isn't infinite. The reason why it isn't infinite is because if it was infinite, there would be infinite friction between the fabric of space-time to the point that it will boil, thus ripping away a portion of our universe, creating a new one which will be in the big bang period, and will have to wait 13.7 billion years to form moderate galaxies. But that's a different story. Also, infinite gravity means that the gravity will pull the universe together with infinite force into a singularity that will be destroyed because of one black hole. See what I mean, infinity isn't possible. Oh, also, once our universe gets destroyed, the infinite gravity of a black hole will go after the other universes, and since one of them has to have a black hole, they will form a supermassive black hole and destroy the multiverse. But there are millions, billions of black holes in our universe right? So we wouldn't be standing here right? See, no infinite gravity.
Your probably wondering, "How about the infinite mass and infinite singularity"? Well, I got an awnser for that too. This time, we'll start with the mass. You see, if something has infinite mass, it is supposed to make an an infinitely sized well in the fabric of space-time. But that's not possible. The fabric of space-time is only for the universes, not the multiverse(s). That means our universe will technically turn into a well with things shooting toward it at the speed of light. But there is a problem with that too. A theory says, it takes an infinite amount of energy to accelerate something at the speed of light (besides a light beam). But that's not true.
Since you can make a light beam go faster than 180,000 miles per second, (the speed of light) we can use a proportion to solve this problem which is, Mass of light over speed of light equals Mass of object over x. You can easily see that it won't be infinite. So that means that the stars and beams of light and asteroids and galaxies and all the other things in the universe will shoot toward it at the speed of light or faster and incinerate. But are we incinerated yet? No. Are we rushing toward our doom faster than the speed of light toward a black hole which will probably destroy us in a fraction of a fraction of a fraction of a millisecond? No. So that means the mass of the billions of black holes in the universe don't have infinite mass either. They only have a lot of mass that can destroy anything that comes to close to the singularity. And that brings us to our third topic.
"What about the infinity small singularity" you might wonder. Well, I will awnser that in a moment. The infinity small singularity is impossible too. Imagine something infinitely small. None of us human beings can imagine something infinitely small. There is a reason why you can't do that. First, our brains are not equipped to think such things. But that's neuroscience. The second reason is that something can't be infinitely small because there is always a smaller size. Let's use the number line as an example. And lets say zero is the size of an hydrogen atom. There is a negative one right? That's a subatomic particle. and negative two and so forth. As I said before, in numerical terms, infinity is possible. So if the negative numbers are the subatomic particles, and numbers continue forever, that means there is always a smaller subatomic particle.
It's like infinity minus one.
Now back to the black hole I mentioned about. If what I said earlier is correct, this means that the "infinitely small" singularity is not infinite. However, if the singularity was infinitely small, the black hole would destroy itself and the suns and stars in our galaxy is orbiting a black hole with tremendous speed will hurtle with each other and destroy each other and I think you know that almost all the galaxies in the universe have a supermassive black hole in the middle and a lot of little black holes inside the galaxy that destroy stars, and, well I'll leave it to you to predict the effect. (If you can't predict what will happen, the awnser is, galaxies will crash with each other and destroy each other and leave a barren universe.) Oh, and for those of you who predicted what will happen, were not in that situation right now right? See? So no infinitely small singularity. All the infinite mass, gravity, and singularity were not infinite, only to the extreme extreme.

Thank you.
But there are several things wrong with this, an infinitely tiny point is possible even if it's ungraspable in the human mind. Just as in string theory when there are eleven dimensions, we can't visualize higher dimensions, but it's likely they're there. Furthermore, even though there wouldn't technically be infinite mass, there would be infinite density, thus creating infinite gravity at the point of the singularity. An infinite curvature in the fabric of space-time. It's theorized that this hole in the fabric of our universe will open up to new universes, so that's correct in the post. But we aren't rushing towards the black holes because outside of the singularity, the gravity field isn't infinite but becomes increasingly strong as you get closer to the black hole. Also, the gravity of one black hole pulling in a single direction isn't the only thing pulling us, we have to counter with the relatively more powerful gravity of the Sun (because it's closer) and the quadrillion other objects pulling on us, PLUS the expansion of the universe is countering most of the gravitational attraction between galaxies (although some are too close to prevent this expansion of space). Regardless, I have to disagree on the role and importance of infinities in black holes, they seem to play a huge part in our understanding of these stellar husks
ReplyDelete1. While it is true that an infinitely small point is impossible to grasp, an infinitely small point can not be possible. You see, if the infinitely small point was the size of an hydrogen atom, there would always will be something smaller, like an neutron. Thus, there must be something smaller than that, like an electron. And so on. There is also an error that something can have infinite mass. If something had infinite mass, wouldn’t the object with infinite mass be heavier than the universe? And wouldn't that cause, not because of the gravity, but the space-time curvature will make the material of the universe rush to the black hole? Even though the universe is expanding, the expanding of the universe is about 0.000...until it reaches 122 zeros and then a 1. That is a very, very, small number. And since the matter left from the big bang is rushing to the black hole, the expansion of the universe shouldn't halt it by very much. Even if the curvature of the space-time fabric isn't infinity, there are millions of black holes in our galaxy alone. Imagine how many there are in the universe. So the space-time curvature, even though it isn't infinite, the black holes in the universe should bring the universe to a crashing halt. If I didn't mention anything in your comment, please tell me. Thank you.
ReplyDeleteSee, the point of an infinitely small point is that there is NOTHING smaller. It is not the size of a hydrogen atom or an electron, it has ZERO dimension, a singularity where the laws of physics breaks down arising in infinities in our mathematical equations. And I'm sorry if I didn't make myself clear, I agree that there isn't infinite mass, that's impossible. But rather infinite density. That means squeezing any amount of mass into an infinitely tiny point (the singularity created by a sort of domino effect from the gravity) would create infinite density. At this point, AND ONLY THIS POINT, gravity (the curvature of the fabric of space-time) would become infinite according to our equations (which are most probably wrong, I accept that, but for all intents and purposes at the present time, are regarded as accurate). But that's the thing, a singularity at the center of a black hole or even the big bang singularity meets the criteria as having infinite temperature, infinite density, and infinite curvature (or gravity). But the expansion of the universe is getting faster, catapulting many galaxies away from each other, despite their enormous gravitational fields, but there are still galaxies hurtling towards each other such as our own and the Andromeda galaxy. If given enough time in a non-expanding universe, a single black hole could swallow up all matter in the cosmos, but when there are so many and the relatives gravitational strengths of other objects are factored in PLUS the expansion of the universe, not all objects are doomed to falling into these sinkholes of the cosmos. Of course a lot of matter does, but not nearly enough to start an effect that increases gravitational fields of all black holes, collapsing matter (by the way, into another singularity like before the big bang) and reversing the expansion of space-time itself. But, hey, some of this stuff is theoretical and all and not everybody agrees on everything. I enjoyed reading the rest of your blog though, check out mine! I got three more posts in! Salutations! Hey, and follow my blog please! :) Thanks for the interesting conversations!
DeleteWhat you are saying is most likely true, but saying that there is an infinitely small point in space-time is like saying that 100 is the biggest number. But you can add one to one hundred. That means that if you can make something half that size, it will be smaller, right? Even though I'm not sure whether you can make something half of zero, the laws of physics break down at the point of the singularity, it might break down in such a way that to our point of view, it is a singularity, but you know the black hole's singularity? Well, it will be impossible to reach it unless to someone inside the singularity, the singularity is very big, maybe to the point of infinity. And since nothing comes out of a black hole, and it is technically impossible to destroy matter or antimatter, I think that the space of the singularity might actually use the gravity to create a field around it so nothing can get out, or that nothing can get out because particles in a black hole are always smashing into each other. Also, since you can't destroy matter, the atoms will have to fuse together until the pressure smashes them. But that's impossible. So the black hole must have to have a extremely heavy mass but not infinite. But who knows, we may both be right since the laws of physics break down at the singularity. Oh and good news, I'm following you're blog now! Until then, salutations!
ReplyDeleteHaha, these are things even the most brilliant physicists do not understand. It has been a joy talking, I do see the point that if the singularity had infinite gravity, you can't subtract from that outside of that, but I suppose you could if the singularity and our universe were cut off. This question takes us to exciting conclusions. :) The journey of physics is truly a special one! Bye for now!
