Experience in a black hole

06/27/2007 8:00 AM

What will we experience when the earth approach and disappear in a black hole?

Will the rotation of earth increase or decrease or reverse?

What will happen to gravity?

Would the shape be a disk or a sausage?

I'm only guessing here, but I would say death...

The jury's out on which of those is worse.

If Earth would ever cross the path of a black hole, we must hope it's a very big one!

The larger, more massive a black hole, the milder the conditions near its event horizon (which is obviously farther from the central singularity for a big black hole).

As Earth falls and crosses the event horizon of a super-massive black hole, nothing too serious would happen. A slight change in the form of the Earth, possibly a slight change in spin rate, gravity still sucking us down to Earth's surface, although with minor changes due to the black hole's tidal forces.

However, as Earth gets closer to the central singularity, Earth will be stretched in the radial direction and squeezed in the transverse directions, hence trying to become a sausage. Before it can change shape dramatically though, it will simply break up and fall towards the singularity as a stream of rubble.

I guess that our atmosphere will be stripped away first, so really a nasty scenario!

I'm going out on a limb here, but I would say it would probably be an extinction level event, followed by the total destruction of the planet.

To my knowledge the centre of our constellation is a black hole and we circle round it, in a not really stable path.

This means that we are in fact approaching one. It may take some weeks before we really will notice the effects but it all takes that long that we can easely forget it.

The first real effect will be the tides which will get disrupted a bit (with enormous tides when moon, sun and the black hole are in line)

The effects will come that slowly that you really need to be a good statistical specialist to proof that some effects on our planet are to be blamed on the black hole.

So let's blame Bush, easier for the masses.

Hi Gwen, you wrote: "To my knowledge the centre of our constellation is a black hole and we circle round it, in a not really stable path."

I guess you meant "our Galaxy". The path of the Sun around the center of mass of our Galaxy was apparently stable enough to have kept us "up here" for 5 billion years. AFAIK, it will hold us up for at east that much longer. That's not too unstable.

Around 5 billion years from now our Sun will blow up and destroy us anyway, they say....

The milhy way, as it is called.

The time frame may be a bit exagerated but indeed the sun will be the first problem for us. The black hole will clean up the mess.

We discuss a black hole, not a brown.

Re: Experience in a black hole

Hello Chaps, I saw a documentray on Discovery some years ago and the same topic came up. There were these professors talking about space and time and one said that there are no known black holes in our current area of the universe, but there is one particular black hole our there devouring our universe and that day might come where we could be sucked into a black hole. Another commented and said that, buy the time we are in any danger of being subjected to the powere of the universe such as a black hole, earths technological defences would be so advanced that we would be capable to fly the planet to another stable destination. They had diagrams and images of such a catastrophy, very neat and i think we should have more about science on tv rather than murdering, because it forms our mind set. The more we think about space adventure and are encouraged, the sooner we move to babylon 5 time. MM

We have to get past Babylon 1,2 3, and 4 first.

I am currently interested in this subject,because I really intend to test a time-like machine.
First,on Uri Gehler's website,the well known psychic,there is a report,dated august 2004,by a scientist of the US Air Force Base Edwards,CA,who discusses material studies for teleportation,either psychic,or by vacuum(quantum modes),metrics(local modified gravity)ot extra_dimensions,Branes as they are called now.
Read also Mrs Lisa Randall,PhP in Physics,on what she intends to perform.
According to numereous papers on gravity since 1973,there are local and non-local,and metric and non metric theories.
For example,the speed of clocks could be desynchronized wether they are electronic,fine level,hyperfine level and so forth.
The most knowledgeable books seems yo me to be "Lorentzian Wormholes"by Matt Visser.In even tunnel blackhole is feasible(the Schrazchild radius of Earth would be 8,5mm, or 1/3 inch),it's a matter of wether the antigravity tunnel,somehow generated(and I have currently a project to do it)shrinks to 1d BEFORE it explodes due to internal stress.The reverse of exploded wires.You should read my references.T.Y.

Just send Geller into the black, he will then prove his powers by communicating to us his experience.

OR NOT!

On a flat Earth, New York City appears to be a tiny black speck when observed from Kansas City, Keflavik, or Karachi. By the time you get there, it is just another city. In non-uniform space, Black Hole Number 5 appears to be a tiny black speck when observed from a great distance, a moderate distance, or a small distance. By the time you get there, it is just another part of space. Don't be surprised, however, that if it took you one year to get there and come back, a thousand years might have passed in the place you started from.

I wrote to Stephan Hawikings once and I asked him if it was possible for us to already be the out come of what could happen to people when the pass the event horizon. You see, Earth being part of this humongous universe is still only a particle in a vast resource of stars, planets and things that go bump in the night. Who's to say that this universe is not the bottom of something like a vacuum/vase where evreything remains until the vase is tipped upside down. Surely we are expanding, but it could only be because when something like the event horizon of a black hole digests even light, well these items need to go somewhere and like a balloon filling with water, the black hole we are already stuck in needs to expand. Stephan Hawkins, to this day did not answer.
