Physics - June 2006

I brought water in a cup to a boil in a microwave, then pour granulated sugar in to it. (It's to make a solution for hummingbird feeders.) The water, lightly boiling when removed from the microwave, violently churns when I slowly pour granulated white sugar into it.

Am I right in assuming this effect is due to the water being superheated, and the sudden disruption of the sugar being added causes the bulk of the water to boil? Is it air being purged out between the small crystals of the sugar, since the vapor pressure of the water is above the partial pressure of the air? Or something else? Or a combination of effects?

Theoretically, if a particle is accelerated beyond the speed of light would it hypothetically "jump dimensions?" Would it disintegrate, or become something else entirely?

Basically, what is the extrauniveral area (I don't know any other word to describe it) like? If space, time, matter, and energy were created with the birth of the universe, then they do not exist outside the universe. Can our brains even comprehend what that is like? Are there any theories that try to explain this?

It seems impossible that there is no creator.

If our universe was birthed in this nothingness, where time, space, matter, and energy do not exist, then couldn't other universes have been born like that? Without the existence of time, infinite universes should have formed just like ours did. And why have these other universes collided with our own?

Without a deity to create or control this things, it seems nothing could have happened. To me it makes more sense to believe that a deity whom we cannot comprehend, nor do we know how it came into existence, created our universe than to believe that our universe came out of no where and created itself. What do you think?

I've read some other Q and A here on Yahoo about this subject and am still highly unsettled about the accepted answers.
Take this link for example

You all say that it is acceleration that breaks the symetry or ∆a, but what if the acceleration only happens during 1% of twin II's journey and the rest of the time he coasts. Is the entire time discrepency take place just in the accelerating periods? Because during the time that he coasts it seems the motion really is symetrical. And yet by actual experimental data this doesn't seem to be the case. It would seem to me that there must be something else responsible for breaking the symetry. Suppose also that at the furthest point of twin II's journey he stopped and we then accelerated the earth to meet twin II. What happens then? I'd like to suggest something different such as the proximity to mass or matter that breaks the symetry. What do you think?

Ok as I under stand it the big bang theory states at 1 point in time and space that all known matter in the universe converged into 1 area and then was rapidly dispersed and formed balls of gas that formed stars, planets and all known matter in the universe.

There is something illogical about this assessment. That is to say that would a huge black hole have been formed and all matter would have been a black hole or later consumed by a that black hole. What was the force that propelled the matter apart? I say it was god.

This is a short version of a much larger theory.

Imagine this if we connect a super conducting wire (with zero resistance) across two terminals of an ideal battery(again with no resistance) and consider Potential Diffrence across points A & B .(see diagram below)
there will be no potential drop from A to B. Then, Why will the current flow from A to B points considering the fact that current flows from higher to lower potential point.

(+) ------>------A-----------B------->----- (-)

seems very interesting; I know they are based in the transmition of metamaterials , wich have a negative permeability and permitivity or something, but I don't understand much... how come we can have a negative index without letting the velocity in the media be faster than light :/.
(No links pls , I'm too lazy for that :P)

We all know we can create and store data on a pc, the storage of the hard drive can be very large, 2,3,4,5 Gb, Terrabytes whatever, we know that that has it's limit, we can store only that amount of data and it's full.
What about the human brain, it has been storing data since we were born and maybe before that, but when is it full, does it get full,.
I don't think so either, so what is my question?
Do you think it is possible that whatever way the human brain stores data, can or will be applied to computers, there is bluetooth technology, can we hope to connect our brains storage system to a pc in the same way?
