  • My question is not on the functionality, but rather the lifespan, how can scientists possibly determine the lifespan with the lack of time and equipment we have today. They simply can't, that's why it's a theory, but then the question stands, where did this theory stem from?

  • Hi. I recommend you watch the documentary "Processed People". I'm not a troll, just someone who wants to spread awareness. Why? Well, because: "A deadly global pandemic makes one thing abundantly clear: Your health needs to be a priority. Not just someday, but right now. Did you know... Obesity, heart disease, Alzheimer’s, type 2 diabetes, cancer, and other chronic illnesses are all fueled by diet and lifestyle choices - and they make infections more dangerous." This was a quote from the "Food Revolution Summit Website", which you can visit. Please just consider it, it won't cost you anymore than a little bit of time, and you could actually benefit from it. Thanks.

  • I'm assuming we use infinity to describe the density of a black hole because we aren't currently able to measure how crushed particles can really get. If we really knew what the smallest particles were, we'd probably be able to measure approximately how dense a black hole is. Right as a sun turns into a black hole if you could measure the size of the singularity you'd be able to determine it's real density based on the size and density of the star it used to be. To say it's infinitely dense is to say it doesn't have size, but rather it exists in a state of shrinking infinitely. Matter cannot be infinitely dense, as density is the measurement of how tight particles are, eventually they'd stop somewhere or else particles inside black holes would be crushing into smaller and smaller particles infinitely at infinite speed, to say they are infinitely dense is to say that particles can become infinitely small, none of this sets right with mathematics. TL;DR I theorize that there 'is' a limit to the density of black holes, we just don't know what that is because it defies our current measurement capabilities.

  • I don't think anything goes to a single infinitely small point in a black hole. I suspect anything that falls in sticks on the surface (event horizon). I suspect this due to time dilation. You will never get to this center, you will fall for eternity, and experience the life of the universe in an instant.

Of course, we can't let a Black Hole come close to the Earth. It'll be even crazier if a Whitehole is pushing us away from the Black Hole, and the Black Hole pulling us towards it!

  • I think you have to talk about God if you are talking this much about space. There are inevitable questions. How come space and matter can bend the universe into something incredibly abnormal like that are capable? I mean space itself is crazy enough and there comes blackholes. Are they intelligent or what kind of a genius matter coincidence is this? You speak casually about space like it is some sort of intelligence yet it’s scientifically emptiness. How come nothingness can form the absolute magic man? I’m waiting for a video about God, Hawking talked about it all his life

    Renan AlvimRenan AlvimDag siden
  • Ok, so I need to understand, what exactly is the singularity? Because you can’t get matter to squeeze any closer to itself then it already is, and we are saying literally a whole planet squeezed into a drop basically, but with your other video about neutron stars, the core of the neutron star has been theorized to be either a super dense core of protons, neutrons and electrons or a sea of quarks, and I understand that, but how can you squeeze something smaller then a quark? I just thought of something though, there is that thing it was, like, Einstein’s quantum fabric theory or something like that, the smallest thing in the universe making everything up, I saw it on a website so I’m not positive about it, but like, we don’t know what the singularity of the black whole is but maybe it’s made of a film of sorts basically it breaks down molecules by squeezing them tighter together until they burst like with the younger black holes, they squeeze you until your basically just a paste, through spaghettification so what if through the black holes it has the ability to break things down to yet simpler things, since it has as you’ve said infinite mass, and since it is spinning so fast too, it must have to have infinite energy as well, which is something that us as humans would almost never be able to obtain, even using our current technology we would not even get close. Also, you said something about quantum fluctuations, how basically it’s matter and antimatter being created out of nowhere colliding then becoming nothing again, I’ve thought about it for a long time, cause I like thinking, and I don’t do research making all my claims probably useless, but I’ve been thinking, matter and anti matter when collided create a large amount of energy when they collide, where a gram of antimatter can do more damage then anything human made, but I’ve thought, what if that is the other way to reach the smallest theorized building block, of course there’s no way to know and no way to even interact with it, but it makes sense, it gives off an enormous amount of energy which would have to be the molecules obviously tearing themselves to shreds, but they “become nothing” but if you can’t create or destroy matter, then they aren’t, well, nothing, but the massive amount of energy, where does that come from, I believe it comes from not the separation of the molecular structure or anything, but the separation of the literal quarks because they all have a super tight grip on eachother, which without that super tight grip, then they never would’ve been able to even make the first molecule stable enough to connect with another, or maybe, from the molecules of course having opposite charges, the quarks are actually tearing away from eachother in the antimatter and joining the other quarks in the regular matter which then they connect and who knows what happens next, they could’ve either completely destroyed eachother or joined to make something new. Ok, enough rambling, what I’m trying to say is even though a singularity may not have and surface area, that doesn’t mean it can’t exist, so since they exist, how are they getting molecules so close to eachother, well, I don’t think they are actually, I’m thinking it could possibly exist somewhere else, because it may break the ways we see general relativity but that doesn’t mean it’s breaking anything, that just means that it’s somewhere else, and of course, this is all now science fiction, but how do wormholes work, they are a hole, on a 3D plane, but there’s a problem, how do they exist? Well, maybe from expired supermassive black holes, or something, because even though from Hawking radiation all black holes die off eventually, well, there could be something special that happens with certain black holes where they loose enough mass to just become, neutral, they can’t suck anything in anymore, but instead the gravity stops existing within the black hole, allowing it to possibly either tear itself apart still again with Hawking radiation or stabilize, and become a wormhole, everything has a stable point anyway, that’s how we are alive and the suns and the planets and everything, they are stable, black holes are unstable on the outside yet stable on the inside, it if becomes stable on the outside it forms a wormhole... Now don’t take my word for any of this, I probably got a lot wrong, I just wanted to get my thinking out there because I love this kind of stuff, it’s absolutely beautiful and fun to learn about, so if I got anything wrong, please tell me, thanks...

      Thomas WrightThomas WrightDag siden
    • @Normal Human According to an article I just read, it appears that, with electrons and anti-electrons, what happens is the pair annihilate and then give off two photons. With protons and antiprotons, they're not sure exactly by what mechanism it all happens, but the result is the formation of several photons, electrons, positrons, and neutrinos, along with a ton of energy.

      Thomas WrightThomas WrightDag siden
    • @Thomas Wright thanks a lot, this has really cleared up a few things for me

      Normal HumanNormal HumanDag siden
    • @Normal Human I'm not sure exactly. It could be because the quarks that make them up disrupt each other's fields and cause them to cancel out, degenerating into pure energy. But the experiments we've done with antimatter seem to indicate that they do have essentially the same properties as their normal matter counterparts, only with opposite charge.

      Thomas WrightThomas WrightDag siden
    • @Thomas Wright in that case wolf you mind explaining how during, quantum fluctuations, there isn't any left over mass? As of they are merely opposite charges then they should cancel it and form neutrons?
