Cool Vids of Black Holes

those ar crazy

 

There is a new theory (well, a few years old, but of course hasn't caught on..as things don't in science) that is different

Black holes are generally thought to be so strong gravitational wise that light does not escape them.

When we reach the speed of light, time stops...that is the theory now held.

Well, if the gravitational pull is that strong, perhaps light going INTO the black hole gains such a speed THAT IT STOPS at the rim.

Perhaps that is why we see a "black hole".... light , and perhaps time, has stopped at that rim, where the pull is so intense.

If that is the case, everything that is sucked into a black hole basically stops there at the edge, as it has hit the speed of light, or beyond...that's why you can never go into one. How can you, when you are frozen in time??

I like this theory, whether right or wrong, because it kinda fits. If it is so strong light can't escape, then at the rim it must stop light, because light reaches such a speed itself must stop!

So it's not a black hole just because we can't see the light inside it, but also because the light going to it has come to a complete halt.

Chew on that dude for a while!!

 

Steven Wright asked "If you are in a spaceship that is
traveling at the speed of light, and you turn on the headlights, does anything
happen?"

awsomely intresting theories guys, damn you make my brain hurt this early in the morning though!! but very intresting none the less!

 

Ya really Cool way to look at things, just glad it was'nt butt pics hehe.

I wonder if your traveliong lightspeed and you turn on headlights what happens as well, damn good question.

 

That would all depend on where you are at at that time. If you were in front of the vehicle (traveling at same speed, of course), you would see nothing. That follows the theory that light doesn't travel faster just because an object is. Otherwise while driving in our cars we would see vehicles way ahead of where they actually are.

If you were directly beside the headlights you may see the light as either the white light we are used to, or in the spectrum.

If it was a light bulb traveling at the speed of light and you were behind it, that may be a white light, or spectrum. But I'm guessing the white light, since you are actually able to receive the light waves.

Cosmos did an excellent show about traveling at the speed of light. Well, we all know we can't travel exactly the speed of light, as the theory says it's impossible, because time comes to an almost complete stop at that speed.

In that show, a man rode around the block close to the speed of light, when he returned a half hour later (for him it was a half hour as when he approached the speed of light, time for him slowed down), time for the rest was normal. When he got back from his half hour near light speed trip, 70 years of normal time had passed.

So, traveling to a nearby solar system that is, say, 2 light years away, near the speed of light, if you ever returned there might not be anything to return to!

The implications are so icredible it is fascinating.

And just to show you a little bit about the distances in our own solar system is this site

I would love to actually do this. As the author says, just reading it looks unimaginable, but doing it REALLY puts it into perspective!

And for those that don't want to read all that is there...a tidbit.

In this model, the Earth is the size of a peppercorn, the sun the size of a bowling ball (the sun is HUGE!!). The nearest star, Proxima Centauri, at this scale (model)...and I will repeat this again..AT THIS SCALE (MODEL)...the nearest star, Proxima Centauri, is FOUR THOUSAND MILES AWAY!!! Yes, 4,000 miles away. Earth the size of a peppercorn.

I know, I know...brain melt down going on.

Completely ****ing AWESOME!!!!!!

Gotta love Science!!

 

Wait, so you are saying light traveling at the speed of light stops in time? That would mean all light would then be "frozen in time," since light always travels at...the speed of light.

 

That's why some people use the term "Hyper-Mass". (and I think that became a weight-joke shortly thereafter)

Oh well...just goes to show you that no matter what you say and/or do - someone is going to have a problem with it.

You bring up an excellent question here. How can light travel so fast and not actually stop.

Light is in waves, and isn't an actual object, like you and I are. Einstein theorizes that an OBJECT cannot travel the speed of light as it's mass actually gets larger as it approaches that speed. And so more energy is needed to reach it. And time slows the closer an object approaches it.

But for your question..again, light isn't an object as we know it.

How would it stop at the rim of a black hole?

The gravitational pull is so strong that everything stops. Doesn't necessarily have anything to do with light, but the actual speed of things acquired from the exceptional pull of the black hole. Light travelling faster than it normally does, perhaps ten fold. If the black hole is so strong light can't escape, then it must be so strong that light can't enter. That is space/time and light physics.

I'm really just guessing on a lot of this, but it makes sense to me, anyway.

 

That's a pretty interesting theory Chuk. And a good one too~!

I was an uber dweeb in school and read every issue of "Astronomy" & "Sky & Telescope" magazines I could get my hands on. (However, once I discover beer and girls...my priorities changed)
Ahem.
Anyway I haven't done my research and followed up regarding this thread so please forgive me if this has been covered elsewhere...
First, to help understand the power of a black hole, the force and density is so strong, that a black hole approx 1" would be the Earth if it were crushed down. Yes, the weight of our planet; its gravitational pull and escape velocity would all have to be compressed into roughtly 1". And these black holes are HUGE...

So, having that in the back of our heads, your idea gave me two additional theories -

1) Perhaps light does enter the black hole, but we cannot read/see it.
if light (and the spectrum,) cannot, then our vision is limited.) (Here the power of the black hole comes into play)

and

2) Perhaps the rim of the black hole is comprimised of Dark Matter? (This is simply a compositional theory)
