Re: Ask a Scientist

Question how pandemic gets over?
We here every now and then about dangerous germs attacking us,but after a while, hear nothing any more.
Can you be sure all those germs suddenly eradicated and vanished on whole earth?
Aslo, can you be sure that everybody on earth got immune to it? What about those who live in remote places, or next generations,...
I wonder what happens to the germs and their impact!

Re: Ask a Scientist

Can you donate body parts to yourself?

Say Bob donates a kidney to his friend Jim.

Several years later Bob has a problem with his remaining kidney and shortly afterwards Jim gets hit by a bus and killed.

Could Bob's original kidney be replaced back into him?

If so would his body still "remember" it as it's own? Would it have been replaced by Jim's cells so that it was now more "Jim" than "Bob"? Would he still need anti-rejection drugs?

Okay, I'm gonna try this out. Any burning science questions that people would like answered, hopefully me and the other scientists on the forum can answer.

But remember, I'm a chemist, I'm not omniscient. I'll do my best.
LOL! I haven't read the whole thread so I don't know if this has been asked. (It has 49 pages!)Is time travel possible? And multiple deminsions?

Re: Ask a Scientist

I guess quantum mechanics would have the answers.... if what I read is correct we're not only living in multidimensional universes, but time travel is possible.

And, more important, we are all linked.

Now I guess too that every scientists won't agree with me.

What's a good solvent with polar and non-polar capabilities that can specifically dissolve adipic acid and and mix with cyclohexane? (and is not acetone)
Did you already try some good old-fashioned water, with

Or is that a bit Old Hat?

I totally agree! I think it's definately possible and I do believe in multiple universes.

Re: Ask a Scientist

Is it possible to have a magnetic black hole. I.e. a magnetic field so intense that the escape velocity for objects attracted to it, would be greater than light?

What other implications would there be?

Re: Ask a Scientist

Well, your ordinary, standard issue, black holes won't let light escape. Anything heavier than a photon* has even less chance of getting away. What does your special magnetic one do that's more extreme than that?


* i.e. everything: the photon has zero mass, I'd forgotten

I think NotAllThere knows that . . . he's just trying to find out if magnetism alone could pull in light. I guess this is how tellies work?

Or is that zero rest mass?

Hypothetically it is possible, if they are just friends then Jim has to take immuno depressants all the time till the moment when a bus hit him Then you can make transfer of a kidney back to Bob and probably you will need some immune system inactivation, but not so strong as in Jim case and I would say not for the long time. There is no kidney replacement by Jim's cells.

I didn't mean a black hole (gravitational singularity) with a magnetic field, rather a magnetic singularity.

Re: Ask a Scientist

Well, if the objects near the magnetic region had no electrical charge or.. not made of some magnetic material.. then they would not be bothered by the singularity.

Hmm anything that is attracted would end up up either the 'south' or 'north' pole of the magnet.. unless your talking about a Magnetic monopole of infinite gauss. Lets pretend you are.. so some materials will be pushed away, others attracted. Those attracted would see the atoms of the material break down as magnetism strips away the electromagnetic bonds.. hmm you'd get a plasma.. likely fusion will follow once enough material is crammed around the singularity.

If your talking a standard magnetic.. with a north and south pole kinda standard, then, being a singularity, then you've likely got some huge particle accelerator going on, as particles will be attracted to one pole or the other, move to that pole and then be repelled out the other poll. Hmm but the electromagnetic bonds won't handle that.. again, plasma, but this time maybe a jet out of either pole of the magnetic.

Certainly would be great to find one.. free energy for everyone, just dangle a few iron wires through the magnetic field.
