I'm having some trouble with the concept of Black Holes.
For years I was under the naive impression that a black hole was a kind of void that, with the help of immense gravitational force, draws and compresses all matter and light into it to create somekind of supercritical mass.
I've recently been given the impression that the term black hole is simply used to describe any massive object that seems to effect space in this way. Is it possible that a black hole is not a void at all, but actually an object that is so large to our perspective that we cannot perceive the true nature of it's complexity, only the forces that it exerts on our level of perception? Does anyone have any ideas on this?
reality is entirely phenomenal, stop trying to make sense of it
Both are sort of correct. It's an object with gravity so intense that the quantum nature of gravity dominates, and nobody knows how that shit works.
Black holes have nothing to do with quantum mechanics per se. What is special about the black hole is the event horizon, and that is something classical.
This revelation in perspective has given me the some different ideas like perhaps a black hole is a massive planet located on what could be said to be a higher dimension. I find this to be poignant because the implications between the ideas of an empty crushing void and life on a grander scale are immense for the wider perception of our reality
bumping for interest. Don't know much about them, but how nothing can escape. So like is it to a certain distance where it captured into the area?
Black holes aren't real, it's all an elaborated lie
/thread
It's not a hole, it's an object so large you think it's a hole because the gravity it creates is so strong that you percieve a hole because of the force of its vacuum.
If singularities do occur in nature, then it's quite literally a hole in spacetime.
Also it's not 'large', you mean 'massive'. In fact, again if singularities are real, then black holes are the tiniest objects in existence.
and why is the hole black and not some other color?
Similar reason to why you see the sky as blue, your senses cannot process everything they are experiencing so they give you a limited point of view
why do you claim that you know what they look like? you've never seen a black hole.
I'm working with the proposed information at hand, why describe it as a black hole if it does not resemble one?
our brains use black for absence of photons
why hasn't the DEI come out screaming that we need to rename black holes to something less racist?
Imagine you take giant ass scissors and quite literally cut part of the universe, space, time, all of it. That's a black hole in a nutshell. The only thing left is its gravitational field.
Black hole is any object, escape velocity of which is equal to the speed of light. So any object of mass M with radius [eqn]R = frac{2MG}{c^2}.[/eqn]In the case of one earth mass, you'd get a black hole with a radius of approximately nine centimeters, for example.
Thanks for providing the most scientific answer
Except it's wrong. An Earth mass black hole would have a radius of about 9mm, not 9cm.
>An Earth mass black hole would have a radius of about 9mm, not 9cm
What would the radius be for black hole mass = 100 tons ?
>Black hole is any object, escape velocity of which is equal to the speed of light. So any object of mass M with radius
I know I'm the moron, but like any object as like planets, stars, and sandwiches?
I believe so yes, this detail is what compelled me to start the thread.
It's just the point at which gravitational acceleration is so great that our model of physics and particle interactions stop working because of divide by zero errors.
I've worked out how to do. You apply pressure, and then you cut into it or decimate it.
