What if Black Holes Spin Faster Than Light?

Hi everyone, I've been fascinated by black holes lately, and I have this idea I wanted to share. It might sound a bit out there, but I'm curious what you all think. What if the reason we can't see the center of a black hole is that something inside is spinning faster than the speed of light? Maybe it's the singularity itself, or maybe it's something else we don't understand yet. If something spins that fast, maybe light can't even enter it. It's like trying to hit a target that's always moving ahead of you. And maybe anything moving faster than light would be invisible to us because our eyes and telescopes can only see light. I was also thinking that this faster-than-light spin could be what causes spaghettification. You know, how things get stretched out like spaghetti when they fall into a black hole? Maybe the intense spinning creates these super strong forces that pull things apart. I know this might challenge some ideas in physics, but it's just a thought I had. What do you all think? Could this explain why black holes are so black and how they cause spaghettification?

“Black Hole Galaxian Correlational Thesis”

“Black Hole Galaxian Correlational Thesis”

Galaxian formation is done through the mass of Star dust and density of Star formations correlating to a singular point, a singularity, which forms a black hole under the mass of the stars which rips the fabrics of space time itself, for black holes are the entrance of wormholes, which lead off into white holes. These singularity have the power to bend space time with the mass of the stars, for a white hole is another universe opposite and proportionate to ours. This Is because of the space time continuum. It can warp under immense density. The only thing known in our universe with the density to do so is a galaxy, with its massive Star Clouds from its immense gravitational mass. This accounts for other galaxies as well as our own and is a result of the Mass coronal ejection such as supernovas and gamma radiation. Every Star is a singularity in the space time continuum and correlates with other stars and interplanetary Star systems. This also results in the mass ejection of Neutronium, which is an element that only exists in theory currently in science.

Question for anyone, from someone slightly under the influence of cannabinoids.

I'm not academic by any means, but I've recently been lightly looking into the theoretical Hawking Radiation. My lay man understanding is that Hawking Radiation would be a form of thermal radiation. If it does indeed exist, would it be possible to send something similar to a probe into a black hole, that can then transmit data back out of the black hole via the Hawking Radiation? I know that its possible to transmit data via radiation. My depth on knowledge on thermal radiation is incredibly limited, but I'm sure that infrared Radiation is a type of thermal radiation. Infrared Radiation can be used to transmit data.

I have considered spaghettification and tidal forces, but I think my imaginary probe could be sent into a larger blackhole where the tidal forces are more stable.

THC induced question complete.

Is it fair to say that black holes is where our understanding of time breaks down?

What the title says. For instance if you could place a newborn baby on earth and one on the event horizon and then snap your fingers would “time” age the baby any different in the snap of your finger depending on which place the baby is

Isn't our 'Big Bang' just the formation of a black hole on the other side?

Was thinking about this today, and it's probably been discussed but...

A black hole forms when a star collapses right? And the big bang happened in like a millisecond or whatever, and it was insanely hot right?

So wouldn't the creation of a black hole basically slurp up the collapsed star into it and do an infinite expansion inside?

Is it possible that our entire universe is inside of a black hole?

Idk what I'm talking about.

Sorry if this is a stupid question…

How does Hawking radiation prove that black holes evaporate?

My understanding is that it’s essentially saying, two particles will pop into existence at the same time, one may fall into the event horizon and the other will escape? But how is that the black hole emitting information? Does the escaping particle take energy from the black hole with it?

Again, I apologise if this is stupid. I am just trying to wrap my head around how this solves the information paradox?

How do you get your Theory officially out into the scientific community/world?

For years I have been fascinated with Black Holes, and recently I had what felt like an epiphany and as far as I know, I have not seen anything similar written anywhere, though I am not really sure how to check if this theory has already been submitted outside of using search engines to find "Documented" writings.

It has been in my head for days now and seem to just be screaming in my head to put it out into the world, but at the same time I would like to officially submit it for a review, but online it just gives to many opinions on how to submit something in the Scientific community if just a regular person who done self study, but nothing official, just submit theory to a Reputable scientific Journal.

For years I have been trying to understand How a Black Hole is Infinite but Not Infinite and this thought has been in my head since I was a child, but as I mentioned, recently a Theory popped into my head that could explain this.

NOTE: A Black Hole is Mathematically shown to have an infinite "storage" but at the same time a Black Hole will eventually fade/Evaporate.


Edit: Added Theory for others to see. (Will warn I am not so good at explaining properly)

Here is my Theory in a really basic explanation:

First would like ask how is it that Blackholes can Pull into itself an "Infinite" amount of matter, but yet is not infinite itself as it will eventually evaporate or fade?

This single thought has plagued me over the years, and recently a possible answer popped into my head and doing my own research I have not found anything stating anything close to my theory.

Blackholes are actually the Contraction of the explosion from the star.

If you have ever watched an explosion, especially a slowed down video of one under water, you will see an expansion as the explosion occurs and then a contraction to fill in that void, usually followed with a mini explosion due to the force of the matter colliding as it refills that void, then it usually fizzles out.

Now, many may find it hard to believe that a Blackhole is actually a Contraction from an explosion as many believe that the Blackhole is a result of the explosion instead of part of the explosion.

This is where Time dilation is the key element in this theory.

The Collapse of a star can cause a violent explosion massive enough to effect not only the space but also time.

If time dilation fully occurs as the explosion is in its contraction event, then the Event Horizon must be the border of that contraction where time has basically stopped the contraction but not the force of the vacuum outside of it.

This is why a blackhole continues to pull things towards it, not just from the Massive size, but also as a result of the contraction still trying to pull things in to fill the void from the explosion, but due to the time dilation, its not really getting filled as time stops and the blackhole expands outward as the accumulated matter needs to be placed somewhere, and so not getting infinitely compressed (Though matter will still go through an intense vacuum compression which would eventually result in it getting compressed, just not towards the center yet)

To us it seems like a sphere of nothingness that pulls in matter, thus the name Blackhole, but if time actually halted or slowed within the center of the Blackhole (The singularity) and the outside of the Blackhole is normal space time, then the blackhole must also be layered with different time layers as a result, explaining why the closer you get to a blackhole the slower things seem until it just seems to stop going in further.

After a long while, the contraction will get smaller and smaller and time will start flowing a bit more quicker until it finishes filling that void and eventually the blackhole will be no more.

the results of anything being expelled from within a black hole would be the result of explosions happening within the blackhole from matter/particles colliding within it.


This is my theory in a basic explanation.

I really hope I explained it clearly. (I rewrote it multiple times)

How long to reach black hole?

From the perspective of an observer, how long would it take for an object to enter the event horizon?

If the time dilation is severe enough, would it appear that objects just cease to move as they approach the black hole?

Do objects actually get sucked all the way in or is it a field of masses almost frozen in time relative to us?

Let's say someone got sucked into a black hole, they'd technically live longer than anyone by a large margin even though they may perceive it entirely differently.

I’m so confused about the event horizon of a blackhole!!!

I’ve linked a fascinating video that simulates the free fall into a supermassive blackhole, what interests me the most is the passing into the event horizon. I’ve seen many simulations and descriptions that tell me that falling into a blackhole, your vision will envelop in complete darkness whilst you watch the universe blueshift in a shrinking circle till the end. In this video, that is of course not the case. by the time you pass the event horizon, and even the ‘inner horizon’ it seems that the blackhole does not envelop your vision at all, which i’m super curious about. My assumption is the curvature of light hitting you from many directions seems that the blackhole hasn’t fully taken you, super trippy. could someone explain this to me? even in vsauce’s video he uses two examples that have these two different and i’d assume contradicting assumptions. A professional or someone with knowledge please inform me what would you see exactly, in vision perspective of what would happen if you were to fall into the event horizon, and even further on into a super massive blackhole. i would love to know

What’s BEHIND Black Holes?

I’m not asking what’s INSIDE a black hole. I’m curious as to what they would look like from every direction, 360° around them. If they have mass they can’t just appear as a black dot from anywhere right?

If you were on the surface of a star before it collapsed into a black hole, would you even witness a black hole?

As far as I am aware, time passes at an infinite rate outside the black hole relative to an object inside the black hole. So for an object inside the black hole would it just instantly fast forward to the point where the black hole dies? I.e. the object would time travel from the point in time it becomes a black hole to the point in time the black hole dies.

Also this would mean that no object could enter the black hole since objects approaching the event horizon would fast forward (not instantly) to the death of the black hole before they enter it.

So if black holes can spin, wouldn't that give a object it's own spin as it enters a black hole?

So, if you enter a Black Hole It has its own spin, much like how stars rotate. So wouldn't that cause rotation velocity on the object entering the black hole to increase as well, to very high speeds? If so, why would the object get spaghettifyed, it would seem like it would get wrapped up in itself instead. I don't know much about physics, so I'm clueless in this regard, so sorry if I asked a awful question.
