it is true depending on Feynman's explanation of negative energy. http://en.wikipedia.org/wiki/Antiparticle

good idea.. i will make my own one

what is the effect of a magnetic field on a electron? please with equations

what i meant it that the dark matter has a gravitational effect on light... not electromagnetic effect...(by stimulating electrons if electrons exist in dark matter) just like when a light beam passes near to a star or his path will be curved for a little...so what can we say about a galaxy...

Astrophyiscs measured gravitational effect of dark matter surround the galaxies right? as the gravitational lenses

dark matte is a form of ordinary matter as u said ,,,,just interact gravitational forces right?

there's a lot of physics students in Syria havnt ever heard about General Relativity and Quantum Mecanis Applications... just a few peple are intersted in QT and GR in Syria in fact...most physicians after the graduate are teaching physics for students in schools... Unfortunately, physical...

(at first sorry for my bad english) in GR and SR we can easlily measure the position,velocity mass,... of a body in a 4 dimensional place called spacetime and as we know that the large bodies curved the spacetime by gravitational waves, and these waves composed from gravitons and we can...

i know this i got to ask you about magnification: a telescope magnification is 36x-675x what is the measure of magnification?? meters? and what's the meaning of "Brightness" in telescopes?

thank you all for your infos but I am not asking about the money... ...asking about what is difference between the principle of refractor/ reflector telescopes and what to recomend

what is the best telescope? refractor or reflector? is the principle of reflecting is better or the reflacting?

time will be slowed near to the large bodies in space (stars, black holes, neutron stars) cause of curved spacetime i don't think there`s there`s a relation between temperature and slowed time temperature form of energy...and bodies another form, but temperature not matter...

is anyone conisder the dark matter & dark energy? what i mean: is the dark matter & dark energy have constant energy(potential+kinetic)? or not?

well classick physics say the energy of the universe is balanced... cause when energy turns of a form to another it will stay energy (potential or kinetic or...) so...we cansay KE+U= constant btw the universe is limited but with no boundaries (by GR)
