I watched the movie "The Core", in that movie they say that the Earth's magnetisim is based on the rotation of the Earth's core(molten metal spinning at high speeds) so does it have to be liquid metal or anything hot rotating at high speeds could creat a magnetic field? is it possible to create...
Why?
I used to installing dual boot system of Windows ME and XP.
After uninstalling Fedora, I can only install Windows ME/98, but can not install XP, after reboot, the system prompts me "No Operationg System".
Fedora had done something on my hard drive, I used windows recovery console to...
"Startrek" warp core
Hello,
The "Startrek" warp core works on the real physical phenomenon of matter collides with antimatter and energy is created.
But as I was taught, a collision between an electron and a positron will produce two, very energetic, gamma-photons. how can anyone use...
Has anyone seen the hypothesis of http://web.umr.edu/~om/ regarding the possibility our sun is the result of a re-accretion on a supernova remnant?
I looked but haven't seen anything on it in the forum, and was wondering what you'all think if it? :confused:

"A crystal the size of our Moon has been revealed hidden at the centre of a dying star, after an analysis of pulsations in the star's brightness.
The measurement confirms indirect evidence that the cores of all such dying stars -...
Could the center of the Earth's core be a critical mass of U-235 or other heavy metals, sustaining a fission reaction. (or might fusion be possible with the presures and magentic fields there? ). If not Earth what about Jupiter or larger exra solar planet?

Heating of the Earth's core must have a logical
solution, which led me to this idea, the work
done by gravity on vibrating molecules throughout
the Earth moves the surface heat of the earth
towards the Earth's core,amplifing it as it moves
to the Earth's center.This is backed up by the...
"Wobble" of Planetary Core
Friend of mine was asking about the Earth-Moon system, and he brought up an interesting question. As the Moon orbits the Earth, it imparts a slight wobble to the planet, much like the wobble used to infer the presence of planets aroubd distant stars. So he was...
I have not seen the film however in the advertising they say that they must stop a weapon that will stop the Earth spinning. I was wondering what orbital effect this would have on the Earth in realtion to the sun and moon. I also wondered what gravitational effect this would have on us standing...
"Skinny" galaxy harbors massive black hole at core
http://www.berkeley.edu/news/media/releases/2003/04/10_skinny.shtml
What kind of changes to our "rule of thumb" can we expect from this finding?
why is the core of our Earth so hot? what causes it to be so? and why some other stars and planets like neptune/uranus (i forgot) does no have such a hot core? and what purpose does the molten core of our Earth serve?
