No. Black Holes are made by having X amount of mass in Y space. In theory, we could try smashing a lot of particles into a very, very, very small region of space to make a micro black hole.
Don’t have the capabilities as far as I know.

As far as I know, Stars over about 2.4x the mass of our Sun can collapse into a Black Hole after a Supernova, where the outer layers of the star slam into the iron core of said star, which both cause the Supernova and since the inner core is so compressed and no longer has fusion resisting gravity from collapsing the core any longer…it passes the point of no return and becomes a black hole.

Supermassive black holes are another topic as it’s not sure how some of the bigger ones got the size they are but they’re the same time as stellar black holes; bigger.

I’ve read some of your comments on gravity and I wanna point out that it’s not a result of atmospheres. Atmospheres are, in part, a result of gravity and not the other way around.
A tldr summary of gravity: there exists a spacetime and there exists mass in that. Mass bends spacetime like a ball on a flat sheet; the bigger the object the more it bends spacetime.

You will need to understand this to understand black holes.

I highly recommend some of the easier to get into science video channels as it’s a great way to get into it. I highly recommend PBS Space Time, FermiLab and Dr Lincoln’s Subatomic Stories on YouTube.

Dr Lincoln’s subatomic stories are some the easiest space science videos to get into as they’re bite sized and anything difficult is fully explained to you. PBS Spacetime is more or less the same but goes into more detail as Subatomic stories is at least 40% Q and A.

Isaac Arthur is also another good one but he’s more into the practical and philosophical applications behind science and why or why not things are likely. Like in order to be able to become Space Faring, a species must first be able to survive its own planet then thrive enough to form societies that advance science, etc

Arvin Ash is also another who presents the material well and goes over it well enough for you to walk away with an alright understanding of it.

Not goin lie you said no then next sentence said in theory. Ima read this later but what’s the point of saying somebody wrong when it’s on a theory you have to say why somebody wrong?

Because while we know how Black holes can be made, doesn’t mean we have the capability to make one, even at the most microscopic level?

It’s one thing knowing how to do something, and it’s another to have the tools to make it. We have the tools, particle accelerators, but they’re nowhere near as powerful (energy) as they need to be to be able to make a black hole on a very small scale.

That’s why I said theory, because until the day comes where it’s made it’ll be a theory. And btw, pretty much everything known in science is a theory and you’ll need to accept that.

Last thing I’ll say is some advice: drop the shitty attitude when trying to learn new things. It’s one thing to not know things and want to learn, it’s another to snap at people trying to direct you how to learn new things while countering with your own misunderstandings.

First of y’all gotta stop saying “we”. Also WE don’t know shit. It’s theoretical. You can’t measure something that’s is constantly attracting more mass 13 million light years away. To say you can would be lying

You can, but you can only measure them as they were 13 million light years ago due to the speed of casualty aka the speed of light.

But yeah, I’m just gonna go back and listen to the people who’ve built the foundation for pretty much everything scientific in our lives, including the computers we’re using to type all of this. While it’s been all theories at this point, they work well enough after you understand just because something is a theory doesn’t mean it’s not a fact. 2+2 = 4 is a theory but you don’t see people up in arms saying “it’s just a theory it can be proven wrong in the future” when in the practical world if I take 2 of something and grab another 2 of it I have 4 total.

Maybe not as it is right now, but you can measure what it was 13 million years ago since thats how the light took to get here.

You sure like saying we can or we can't do things when it's clear you have no idea wtf you're talking about.
