If I rubbed my hands together in a dark room (no outside light source), could the heat i produce cause Infrared radiation?
Or is the infrared radiation from our bodies dependent on outside radiation?
When a neutron star flucuates into a black hole does the gravity increase tenfold? Or does the neutron star gravity (while turning into a black hole) increase as expected with the addition of more mass?
Ok let me get this straight... so after an electron cloud shifts temporarily due to a photon absorption, the absorbed photon cannot be held onto (because the atom doesn't support that state). And due to this the photon's energy is kineticly transferred to surrounding atoms like a wave, no...
When certain photons with the right energy hit an atom's electrons, the electrons of that atom can shift positions. Visually this is what I'm talking about: http://www.youtube.com/watch?v=L0UJhSvPE5A&feature=related"
From my understanding Heat=the vibration of atoms
When I rub my hands...
Recently I read an article about Japanese scientists trying to create a miniature universe. The article was pretty old, 2006. Does anyone know the status of this experiment, or know where i can read more of their present progress...
Hypothetically if your in a jet or spaceship & are shining a green laser pen out the window how fast must you travel to cause the green light (570 nm) to change into low energy blue light (475 nm)
