Ok so that was misunderstanding.
so if we go back to topic
according to these formulas
Infinite redshift happens if we calculate path of photon which travels from event horizon to infinity.
But if photon goes smaller distance it still has some remaining energy left. If we use energy of another particle to refill loss It can go a little further. So it can climb up this lader until escapes completely
Also I found another problem with this formula of gravitational redshift:
redshift between radius and infinity is infinite at horizon level, but below it becomes imaginary.
That is quite an absurd, because infinity is more or less valid but imaginary absolutely is unacceptable in physic in any form.
So I suspect something must be wrong here.
Both beams will appear to move at C when hitting the sensors, though, and if you could set up a system that measured the speed of part of the beam inside the time dilated area, that too would show the beam to be traveling at C, since it measure it in the dilated frame of referance.
It is important to realise that this is not a slowing of the light itself, it is a change in time flow, things just happen slower inside the time dilated area than outside.
One example of this effect is the result of the Shapiro experiment, where a radar signal was sent from the Earth towards Venus so that it passed by the Sun. The return signal showed the predicted time delay(that is, the predicted compound delay of gravitational curvature of the signal and the gravitational time dilation) within accuracy limits.
Several space probes have done similar experiments, and the effect must be taken into account when designing and using probe radio sytems. Satellite navigation systems(and other satelite systems) where changes in travel time of the signal may cause problems in the results will have to compensate for the effect too.
Huh? I disagree with this. Light travels at C from all frames ... if we see light near a black hole it still travels at c from our vantage point as well as from a local observers vantage point.
The only thing that could make light take longer to get to a target would be if it curved so that the path was longer.
Light doesnt travel slower in a gravitational well.
If I understand it well then when you move towards horizon redshift between 2 vertically arranged points increases until it reaches infinity in zero distance.
resulting infinity divided by zero redshift at horizon level.
that is the only reasonable say to prevent everything from escaping.
because in other way we can use external refueling to climb up.
In this way everything that reaches horizon level should be ripped apart instantly, no matter how big is black hole, because acceleration gradient between 2 points is always infinite.
Light always travel at C in local frames of referance, you can not measure the speed of light in another referance frame(like the observer close to the black hole), only your own, and there the time dilation factor would be equal for you and the light. Therefore, regardless of where you are, light always move at C.
Or put another way, I would say that the concept that light always moves at C to an observer requires light to be subject to gravitational time dilation, if not, light would appear to move faster to an observer in a high gravity field than one in a low gravity environment, since his/her time would move slower.
the formation of black-holes is not possible in the first place
because , black-holes inorder to form , can only do so one dimensionally
the focus of the rotation can be from the N or S but not both at the same time
North, you will keep your own ATM out of this Q&A thread.
Get up, a get-get, get down.
I am not sure what you mean by no acceleration is felt, what is it that does not feel acceleration?
Solar mass black holes take about one second to form an event horizon, so some photons do escape, but the last photons reach the event horizon from the inside, too late to escape. If the hypothesis is correct, these photons will travel inside the event horizon for trillions plus of years, relative to both inside and outside observers. Likely some of what we think we know about black holes and relativity is wrong, but that probably does not mean we need to reject the existence of black holes, nor relativity. Neil
first we need to calculate redshift amount between close alder steps.
v=sqrt(2g(h1-h2) where g= GM/r
this velocity change between lader steps can be used to calculate dopler shift.
g increases linearly while we move towards mass center.
so assuming that distance between lader steps is dh we get this:
dv=sqrt(2GM/r *(dh) )
this proves that Doppler shift between closely spaced lader steps is never infinite and no matter how close to mass center, It is always possible to climb up some small distance.
In contrast escape velocity is calculated assuming that dh is infnite.
however my calculations now depend on fact if gravity can slow down light speed itself.
However how will you explain this:
According to your theory if we send light beam through massive tube it will require more time to reach destination.
But if we slowly drop some ball through same tube it will reach destination faster than ball going same distance at same initial speed in free space.
Something must be wrong here
How can gravity bend light if there is no change in 'velocity'?
Special relativity does not override general relativity. It's the other way around.
c=c for special cases, ok?
And B releases a series of photons. C, B and A will measure the speed of the photons at the speed of light. If A releases the photons C,B, and A will agree that those photons are moving at hte speed of light.
can you explain somehow that fact about light speed.
R1 and R2 are in gravitational well while T and R3 are in free space
If light speed is constant beam travel time between R1 and R2 will be less than 1/3 of total time. Because R1-R2 clocks tick slower so for them light will appear to propagate in speed greater than C
How do you solve this?
I also expect that light speed should be constant , but something seems wrong here.
However in gravity field this is not the case, because acceleration does not depend on particle mass and it is theoretically seems possible to exceed c.
In gravitational field even particle with infinite mass will continue to accelerate at same rate like particle with low mass.
In the Shapiro experiment things were a bit different:
Venus ♀ <========== radar signal =====> ⊕ Earth
The radar signal was bounced of Venus past the Sun. So therefore the sender and reciever was in the same reference frame, and their time flow would be syncronous. So when the result showed that the traveltime was longer than it should have been, and that matched within the accuracy limits of the experiment the predicted compound delay of curved space and dilated time in this system, that shows that light is affected by both. if only one effect affected the light the result would be different
You said "The only thing that could make light take longer to get to a target would be if it curved so that the path was longer." I interpreted that to mean that you were claiming that the light would be affected by curved space, but not by curved/dilated time.
So what I meant with it being a different effect was that light takes longer to pass a massive object than curvature of space alone accounts for, so you have to take gravitational time dilation(or gravitational time curvature) in to account too.
I am not confused really, but I suppose I should have mentioned that the effect of going up the well would take away the energy gained.
Gravity will not accelerate anything past the speed of light in the local reference frame, though there are some theoretical things like worm holes that connect different parts of space time and warp drives that could cause a global speed higher than c by using warping of space-time. The thing with these is that no mass ever reaches c in a local reference frame, so they do not really violate the constancy of c. Anyway, this is realy a subject for another discussion.
An infinite mass wouldn't accelerate at all, though you may find that it would pull the universe it was in into itself in a big crunch event.
