I had a thought about black holes.

[RandomThoughts]

They are spoken about as being really massive, and that is true by gravitational effect.

Since as something approaches the speed of light, it approaches infinite mass, and lives in time slower, has anyone thought that a black hole is really just one particle that drops slightly under speed of light, giving it huge mass? And since time dilation would be in effect, the speed drop to lower mass takes billions of years. So a single particle could be a black hole if it is below the speed of light. And other particles would not reach it by its dilation effect on space time around it.

Except "black" is really just a colloquialism for "MiddleFingerMom-colored".

16. Umm ... I don't see any mention of the Big Bang

5. Um...

A particle can't "dip below" the speed of light, it must be accelerated towards the speed of light. Particles, or units of matter really, do not travel at lightspeed, not ever. And it takes infinite amounts of energy to accelerate, because as the particle gets more massive it takes more energy to move it. There are theoretical particles which travel at light speed, but the only things we know of that go that fast are photons. Also, the time dilation is relative. For the theoretical particle, time takes forever to go by, but for you and me, time travels the same as ever.

Black holes are the result of stars of a certain size gathering so much mass that the gravitic force overwhelms even photons. Beyond that I don't know much about black holes, except to avoid Disney movies about them.

I would also add the OPs postulate that the particle is sub-light but still within time dilation effects that would only be true if you were observing from the particle. Anyone observing the particle would see it moving faster.

Dude! WTF did they put in the coffee?!?!?

[RandomThoughts]

9. you make a good point, the particle would have to move, just below

light speed while stationary, or the black hole would be observed to be in motion. I wonder if two particles could orbit each other at that speed, allowing for the speed without the motion.


However that brings up a differnt situation.

two situations.

1------>2
1<------2
first line item 1 is moving at 2 at .99 light speed.
second one 2 is moving at 1 at .99 light speed.


Relativity can not be truely relative. because in the above situation. the two items are moving at different speeds. But relative to each other, they both see the other as moving at .99 light speed and themselves stationary. So while on either 1 or 2, you would think the other is moving at you. From either example it would look the same. So which one would see the other moving slower or faster in time? They simultaniously are the faster and the slower. Unless there is some baseline 0 speed somewhere.

That question should mean that the galaxy has a 0 speed somewhere, or it is not all relative, so each object can be said to be moving at some speed. relative to galactic 0 speed.

Havn't figured that out yet.

12. I think you're overlooking the massive gravitic effect of black holes.

Galaxies form around supermassive black holes. You cannot get that kind of gravitic effect without a great deal of matter. Look at matter as a stable form of energy, if that helps; matter as we know it was created inside stars and is essentially what happens when there's so much energy present it has to stabilize... and heavy elements are formed. Energy has gravitic pull as well as matter, though much less, and this is something which we'll probably be able to explain when we finally understand gravity. In the meantime, since matter is stabilized and concentrated energy, the gravitic force is stronger in it, and if you're going to have an object in space which so affects spacetime that light itself cannot pull from the gravitic well, there has to be a LOT of matter there.

There's something interesting in Dr. Hawking's view that black holes emit some form of energy. Good sci/fi material there, methinks! ;)

[RandomThoughts]

8. I understand that. however.

But a photon of light has mass, you know that from solar sails. So if you dropped the mass of a photon out of light speed, then it would create a black hole if not done in the correct way.


I found that thought interesting.


And yes I know photons of light always travel at light speed.


Here is another one, if you could travel faster then the speed of light, and it did have backwards time effect, then you could instantaneously travel to any point, if you could reach that speed, by moving back in time, the same rate as it takes you to travel some distance. That would explain what the Kevin Spacey said in Kpac about instantenious travel by being light.



Just thinking up scifi stuff, that would seem to be able to explain stargates in scifi. Although most stargates use multidimensional wormholes, in a space like warping idea, that could be another scifi explanation.

10. It's past time something was moved OUT of the Lounge.

11. That would have been a better place to post it.

Funny, I just commented about being moved into the lounge a few days ago. LOL

That is funny.

14. Dear Random...

Why do you have Burgess Meredith as a signature pic?
Just asking. I know nothing about black holes.

[Dr Morbius]

15. I think that's Meridiths role as a librarian in a memorable episode...

...of The Twilight Zone.

Burgess Meridith was never better than in that episode, and perfectly cast, too.

17. Long story short: no.

It just doesn't work that way.
