Since time slows as you get closer to a black hole. Can you ever really reach the black hole?

Question

Stephen Hawking has stated that black holes will eventually evaporate due to Hawking's radiation. If time slows so drastically as you approach a black hole, would you finally be released from the black holes grip when it eventually dissipated and see the last days of the universe?

According to General Relativity, gravity can also cause time to slow. If applied to the Twins Paradox, a twin that is an intense gravitational field will age more slowly than their sibling. Take the field away and they are now different ages although born on the same day.

In my proposed scenario, as you approach the singularity of a black hole, gravity approaches infinity. If gravity approaches infinity , the passage of time approaches zero. This gives the black hole time to dissipate which releases the intense gravitation field much as releasing the twin in my example above.

When released, the black hole survivor is able to witness the end of the universe.

Is this hypothesis basically correct and if not, why not?

Answer 1

Gravity (as well as velocity) does have an effect on time, but as braxton_paul has said it depends on the frame of reference. For someone falling into the hole, time would run at the normal rate, while a distant observer would see them getting slower and slower but never actually crossing the event horizon.

fwiw, this effect has to be taken into account with GPS systems - the clocks in the satellites are running at different rates to the ones on the ground.

Answer 2

A black hole is a theoreticl entity.
It is postulated that when a neutron star collapses small enough the surface escape velocity equals the speed of light.
If a person fell toward a black hole he would feel his speed increasing but his watch would remain constant.
A remote observer may see the falling body slowing as it approched the surface.
This may appeal to the frame of reference advocate,this assumption would not hold true in real life with a black hole.
Hawking radiation says that when two virtual particles emerge near the event horizon,one is captured and the other escapes as radiation and diminishes the black hole by a coresponding mass.
There is no mathematics to shore up this theory.
There is no proof that black holes exist.
Lets look at black holes in terms of other celestial bodies.
With a sun,a planet,a neutron star and a black hole the mass and gravity is concentrated at the center
The surface orbital velocity varies in each but can be calculated.
As a satellite moves away from the surface orbital velocity decreases in all cases.
If yiu drill a horizontal tunnel below the surface the orbital velocity also decreases due to the mass and gravity between the satellite and the surface.
The mass and gravity of a black hole is concentrated at the center after you penetrate the surface,this makes the orbital velocity greater than the speed of light.
A black hole contains no space, it can not even separate itscenter from its event horizon 3km away.
A black hole would be pelted by random photons from all directions, some would be trapped at the surface others would blast right on by.
The quantum effect would cause some photons to spiral away from the surface causing the black hole to glow dimly in white light.
Some photons would spiral just below the surface they could not spiral in and they could not spiral out
The quantum effect would trap slower photons at the surface,unable to spiral in or out and unable to maintain orbit.
A black hole needs a face lift to take it out of the realm of non-viability.

Answer 3

sounds love it incredibly is time for some information approximately black holes as defined by using Einsteins's familiar Relativity a million) If a black hollow is sufficiently super (and in isolation), you may pass contained in the direction of the form horizon with out being spagettified. opposite to good judgment, the tidal forces (the differential forces) of a black hollow on the form horizon are inversely proportional to the mass of the black hollow. The tidal forces on the form horizon of a small black hollow are plenty larger than a super black hollow. 2) as quickly as contained in the form horizon, you have little or no time previously you hit the singularity on the midsection of the hollow (you would be shredded previously you hit the singularity inspite of the size of the black hollow on condition that tidal forces improve the deeper you pass). 3) The singularity (infinite area-time curvature) on the midsection of the hollow is envisioned by using familiar Relativity. as quickly as contained in the form horizon, you're no longer to any extent further a spatial distance faraway from the singularity - you're a temporal distance away and might incredibly would desire to shuttle back in time (impossible) to ward off the singularity 4) Time dilation is relative to observers outdoors of the black hollow. in case you fall by using the form horizon issues will look prevalent (regionally) to you for the two time pass and spatial distances - that's between the conventional strategies of relativity 5) There are distinctive styles of black holes that are allowed by using familiar Relativity. some black holes would have severe angular momentum and electric powered charge the two one among that can impression the indoors srtructure of the holes. 6) some black holes have 4 distinctive area-time areas. 2 of which seem to be 'prevalent' universes. they could be separate universes or 2 get admission to factors into an analogous universe (familiar Relativity would be unable to anticipate which). there is not any conventional thank you to shuttle between the two areas.

Answer 4

Interesting and well-thought-out question. I assume that the slowing of time you mention with regards to approaching a black hole is caused by the tremendous increase in your velocity which would be brought on by ever-increasing gravity. Time would indeed seem to slow down, but not for you! Relativity has shown us that the slowing of time relative to increases in velocity holds ONLY for observers outside your reference frame, like someone back on Earth who could somehow monitor a clock you're carrying. For you, that clock would run normally, but for the distant observer it would slow significantly.

All this is because Einstein and relativity have proven that time is not a NATURAL feature of our universe---there is no Cosmic Master Clock ticking away the correct universal time. In other words, time is not an absolute phenomenon but merely an 'invention' we've come up with to separate events into past, present and future. Therefore what we perceive as time is strictly relative. A crude analogy would be the time in my time zone (..Pacific Standard Time) and my friend's time in Chicago (..Central Standard Time) The time where I am is 3:45, but where he is in Chicago it's 5:45. Which time is correct? They both are, because time is relative. There is no 'real, absolute time' that is universally correct.

Answer 5

yes black hole is really there but time never slows down for anyone so feel like it is slow because when u go through something black u think that ur still going slow but u arnt so try that in a black long space and u will come to know

Answer 6

Is this theory and conjecture or do we know of someone whom has went to a black hole and back again.To enlighten us to how time slows as we approach the black hole.

Answer 7

Time doesn't wait for anybody, not even a black hole. Steven Hawking is a great person, he knows most of everything but dealing with time...is just impossible....No offense to him.
But lets say time did slow down...I think by the time you reach the stupid blackhole, you will be somewhere else...lolz...
but i thought something that is so strong would pull you in faster....???

Answer 8

My estimate is that when this occurs, both you and I will be long gone, and our dust scattered. The theoretical discussion, while interesting, seems to deal with things so far distant in the future and distant in relative distance from Earth that I will now turn to more immediate jobs like balancing my check book.

Kind regards,
