Jeez jeez jeez! Make sience with me!

 

 

 

I'm taking Physics next year, so I'll see what that's like, it seems pretty interesting.

 

 

 

 

 

 

 

If you like the little details (or the really big ones, of course), then Physics is the one for you -- Chemistry is, in a way, just Physics applied to lots of things at once -- so many that sweeping, general statements have to be made. I suppose it's got bits about atoms and electrons and whatnot, but that's just getting into the realms of Physics.

 

 

 

 

but I focused on black holes which had to encompass relativity and quantum mechanics

 

 

 

 

 

 

 

 

 

 

Did you know Stephen Hawking is starting to think black holes don't exist? There was something on the Discovery Channel about it, but I don't really remember.

 

 

 

 

 

 

 

And quantum theory is my favorite area of physics, I got interested in it off schwordinger's cat.

 

 

 

 

 

 

 

It wouldn't surprise me. He's gone back on a lot of theories he made bets on previously. Like the information paradox etc.

 

 

 

 

 

 

 

I don't really see how he can say black holes don't exist though, they seem fairly, well logical if you look into it.

Too bad that's impossible. :wink:

Personally, a hole in the space/time continuum is hard enough for me to comprehend :P.

I've heard somewhere you actually could look into a black hole (assuming you wouldn't rediculously deformed or killed) and come out to tell the tale if you had a rope tied around you. Total grabage? Not sure. Maybee.

xD

 

 

 

 

 

 

 

I knew that there was a reason why you spelt it wrong...serves me right for not reading.

 

 

 

 

 

 

 

Chemistry is my favourite science. I enjoy the practicals, when a teacher tells you not to look at burning magnesium, I suggest you don't!

Unfortunately, my eyes are attracted to bright things, including burning magnesium....

Oops, terrible choice of words by me :P

However, if you believe Stephen Hawking, you can see out, in a manner of speaking.

 

 

 

 

 

 

 

Allow me to explain. What we currently see as light from the stars actually was emitted many years ago. Thus we are not actually looking at the light currently being emitted from the stars. Even the sun's light takes about 8 minutes to reach Earth. That said, the light being drawn into a black hole would be visible from atop the singularity within the event horizon. Due the the time warping (See #1) it might even be possible to see all light which had entered the black hole, simultaneously. Thus, you could see all time that had ever occurred since the beginning of the black hole, up to the current time outside the black hole. Nifty, huh? Too bad nothing that entered an event horizon could ever come out, unless capable of faster-than-light travel itself. (See #2)

 

 

 

 

 

 

 

#1 According the the Theory of General Relativity (Chapter 13), light is bent by gravity. The stronger the gravity, the harder the bend. Now, light before bending is travelling at 186000 miles/sec, approximately. As light bends, it experiences a change in acceleration, producing a change in velocity (dv/dt). This makes the wavelengths of the light shorter, storing more energy. At some point, there is enough energy (E) stored that the accelerated light particle can overcome it's mass (m), and travel faster than the recorded speed of light. © The particle then travels faster than the light particles in the surrounding galaxy, seemingly moving backward in time. This is hypothesized to actually become a visible phonomenon to us at the event horizon. We do not see visible light exiting the black hole, because as the light wavelengths are compressed, they turn to X-rays, then sometimes to gamma rays. If light slingshots around the event horizon, and never gains enough energy to warp time, it exits at this super-charged state, largely invisible to the human eye.

 

 

 

 

 

 

 

#2 The simple answer is that a particle must reach escape velocity to escape from the pull of a gravitic body. The escape velocity at the event horizon is the speed of light. Now imagine that instead of just a particle, a camera was inserted into the black hole. Every particle in that camera would have to have enough latent energy to move itself faster than the speed of light, away from the singularity. Even if this were possible, the camera would, if the particles remained in the same order, exit the event horizon before it was inserted, thereby adding excess matter to the universe. Not good.

 

 

 

 

 

 

 

Which brings us to the age-old question: If a tree falls in a black hole, will it make a sound?

I am currently taking Chemistry. My teacher makes all the work college level. I had to make up a lab today and I have quite a few deductions to make before Friday. >.< I don't find it hard, I find it challenging. ^_^

 

 

 

 

 

 

 

I took Biology my 9th grade year. Passed it with a B. I LOVE Science classes, and I think that all kinds of Science are beneficial to society. :D

I enjoy nearly all the sciences I do at school, but physics is the only one that i'm looking to take any further. Hopefully to degree level.

 

 

 

 

 

 

 

I find physics concepts so fascinating, especially theoretical physics. I threw myself into a project late last year at school and ended up making it surprisingly detailed. The general topic idea was space, but I focused on black holes which had to encompass relativity and quantum mechanics. I found it so interesting to research and do.

 

 

 

 

 

 

 

If anyone's interested I could copy and paste the text into this topic in very small text :P I don't know how to upload word docs.
