Ask a physicist anything. (6)

Maybe some sort of energy, a gel, nanaomachine cloud, or light.

Energy(electrons??),Gel, Nanaomachine cloud, light(photons) all would be pulled into the singularity just like any other physical object.

 

[Tuddrussell]

But can they be pulled out? Is there any way to... turn off a black hole. Maybe drop a white hole into it?

No, there is no way. White holes are contradictions in terms: a white hole is the time reversal of a black hole. Which just means that you got your time coordinate wrong.

Say I made a white hole in a lab...

 

[impblack]

A white hole it's conceivable if a special kind of matter/energy exists, exotic or negative matter. Fist i have to point out that this is a theoretical prevision and not a scientific fact. But many try to study ways to prove if it exists or not.

I theory a white hole would expel matter, some claim a white hole was the beginning of the universe. Furthermore a white hole would repel everything from it even the energy that it is based upon, accounting for their extreme instability. That instability also accounts for the lack of observations of white holes.

But white holes and black holes are extremes in terms of space-time distortions. The "warp drive" seen in star trek movies was already theorized by our science... but it needs the existence of exotic matter much like white holes...Actually there are many thing from science fiction that ca be explained by our understanding of space-time geometry

If you held a magnifying glass to the sun, then pointed that light refraction at another magnifying glass just below it at the point where the light is most concentrated, and did this over and over repeatedly...

So say like 8 stacked magnifying glasses where the ray of sun light would be filtered through at the point of highest concentration, what might be the end product of this?

Would it be a small nanoparticle but of pure hellfire or would it be nothing at all since it's been filtered so many times?

You can't make something in the lab which will continuously decrease in entropy.

Reed Richards could, and Tony could make a quick and dirty one in a cave with a box of scraps!

Only if the Writers let them.

 

[Tuddrussell]

But they COULD. Which is the point.

And Samantha from Bewitched could twitch her nose & pop one in a drink, the problem is this section is Physical & Life sciences, not Fictional Writing.

 

[Tuddrussell]

It is physical and life sciences, the fictional versions of such fall under that overall catagory as well. That, and the thread is ask a physicist ANYTHING.

TL;DR: I win.

Ah but the above post are Questions, so you don't win

My avatar IS the Question, so I win forever.

Say I invented a ghost in a lab, then threw it into a black hole. What heppens?

Define Ghost and its composition!

 

[Tuddrussell]

A ghost is an intangable and trasparent (At least some of the time) humanoid. I already posted what they could be made of.

OK you can go out and play now!

Your condescension is noted. Anyway, back to the topic. Is there anyway to survive or stop the end of the universe? It would be very boring without us around.

The answer is a simple NO!

 

[Wiccan_Child]

But they can't. A white hole is a contradiction in terms. It makes no sense to hypothesis what would happen if you made one, any more than saying "Suppose I made a square circle...". You're probably thinking of something that you think is called a white hole, or which is colloquially called a white hole - but, in fact, is not.

As Grand High Wizzard, I overrule that remark.

Depends on how the universe ended. If you could go to another universe, sure. If you can't, no. Besides, the universe trucked along for 13.5 billion years, all of which is interesting and fascinating, and our paltry 70-odd years aren't any more interesting.
