I saw on PBS that blackhole occurs when the sun is dying, then eventually it will decrease or increase in size? Then collapses and sucking surrounding planets into it and all things into it. But will it turn into a time travel tunnel for a long period of time?

First off, that a black hole sucks everything around it in is basically a myth. The pull of a black hole at a distance r>Rhorizon is equal to the pull of any other equally massive spherical object. So if the sun collapsed into a black hole, ignoring the fact that it's not nearly massive enough (by a factor of 10), we would still feel the same pull of gravity and remain in the same orbit. That said, in a quickly rotating black hole, there is an inner horizon where the inescapable fall towards the singularity at the center of the black hole is halted. Inside this second horizon space remains spacelike, meaning time travel is possible, unfortunately escape from this inner horizon is impossible because there is still the area between the inner and outer horizon which is one directional and impossible to penetrate.

Briefly, black holes are singularities where time actually stops ... so forming a time tunnel would not be possible. Once something enters a black hole, everything that is occuring is halted at that point, but the gravity well is so strong that anything that would enter the black hole would be utterly destroyed.
Hawking gave an excellent explanation about black holes in his book "A Brief History of Time." I am certain it will answer this and any other question you may have regarding this subject.

As far as know a black hole an area that has great density. The object is so dense that it has a gravitational pull greater that of 1,000's of suns/stars. So with that, the black hole is nothing other than a fallen star that sucks in and crushes matter. Other than that, there is nothing known that a black hole is capable of time travel. However, if created, a field of negative energy would be able to do time travel as it creates a sort of "Wormhole".

I believe it is a trans-dimensional portal since all holes must have a bottom-my view of space is it's like air and if you had a "hole" in a handful of air-since that is just various clear gases in 1 point in space in time and you couldn't see the other side or a "bottom" to the hole than it would lead to another space and possibly time. Everything sucked into can't simply disappear-it must go somewhere-energy can be neither created or destroyed so it all leads somewhere.

nope, the sun is not massive enough to collapse into a black hole
larger stars collapse into black holes
so far there is no theory that a black hole is anything like a "time travel tunnel"
anything that gets close to a black hole is crushed anyway
black holes eventually evaporate over extremely long periods of time as their mass is converted into high energy radiation

There are in concept "susceptible sectors" in black holes. areas with extra good and lessened gravitational forces. it truly is theorized if it have been available to navigate those susceptible sectors one ought to commute to the singularity with out suffering the outcomes of spagettification, etc... Spagettification is the call given on your physique/deliver being ripped to the sub atomic point by making use of the modifications in acceleration forces from the extra forward areas of the deliver vs the back. think of of you being stretched into the black hollow as a string of spaghetti. additionally it may be thrilling to contemplate what precisely happens at this singularity, with the aid of fact in theory that's an infinitely small factor. this is area and time are one. yet i think of that's the place wormholes and different theories come into play and who's primary with of you ought to finally end up in a parallel universe or substitute life.

No I do not think so. Furthermore we would not be able to breathe in a tunnel going upward like that. Perhaps that is the begining of the end of life as we know it today.

As long as there is a strong gravitational field. You will have time dialation! As long as you dont get too close to the event horizon, I heard that can get kinda nasty!

no, scientists used to speculate this, but now realize that the black hole would destroy anything that got close enough to find out. Would be fun, though, to be able to travel through time and space, wouldn't it?

Since we are uncertain as to what goes on in there, anything is possible.
