Spot on DW. I think that's one of the biggest problems with the way we teach, we seem to like paradigms. Like the old event/observer model to explain things, in practice an observer is nothing more than another event (it just happens to be in a sensory organ). But it's easier to explain that way.Read my post regarding sound.... the falling tree will create pressure waves through the various mediums around it, it is not a sound until it hits the ear drum it is mearly a pressure wave so if their is no eardrums to translate the pressure wave into what is translated as sound then it has no sound, its just atoms bouncing together in a wave pattern.
Again dont try blend basic school physics with quantum theory or you'll just confuse matters, school teaches us about sound waves but they are not sound waves but pressure waves, sound waves dont exist in their own context of the word.
Example... close mouth and hold nose and blow, your ears will 'pop', this is because the pressure has change in the ear canal and the ear drum has changed shape in response hence you hear a pop; a sound!, now no 'sound wave' was ever created you just altered the pressure in you ear canals.
Its can be a hard concept to understand especially when you are taught about sound waves at school but these pressure waves can't be tagged with the term sound wave until they have been heard and even then its a misleading name as they are still pressure waves, you can usually translate these pressure waves easily through air and water, but consider solid steel that has vibration when you touch it yet you here nothing, it is vibrating thus it has pressure waves running through or oscillating within it now you wouldn't normally call the vibration a sound wave but put it against your ear and and the vibrations (pressure wave) will be translated into sound if within 20hz -20khz frequency.
I take it you've been to the pub as well (not buying that one)Gravity warps space time, light follows space time .... quickest way to answer that
No! no beer for me tonight, its an often asked question in quantum physics but although at first its seems like it going to be a brain-buster it really is a straight forward concept, photon is like any other boson in that its a force carrier (excluding Higgs Boson as this is like a central piece linking quarks, leptons and bosons). The fabric of space time although still an unknown concept is affected by gravity and warped in some way, photons even though massless in the standard model still permiate through space time if the light travels long enough it also has red shift because over the billions of years the universe has expanded stretching space time and thus also stretching the waveform of the photon, this in itself hints that it is effected by anything that would stretch spacetime.I take it you've been to the pub as well (not buying that one)
Browse the Quantum physics forum Des .... now even i get totally confused in there lol
Windows 7 .... split screen optionThe problem as I see it,I like this forum,so could I be in two places at one time ? lol
I had been to the pub Yep, seen that proposal and it explains the photon being "bent" towards the singularity. The model used is like a marble rolling on some "cloth" (the space/time) that's been streached down at one point forming a funnel like structure. That doesn't explain why no light comes out of a black hole in any of the explainations I've seen though, any clues from your reading?No! no beer for me tonight, its an often asked question in quantum physics but although at first its seems like it going to be a brain-buster it really is a straight forward concept, photon is like any other boson in that its a force carrier (excluding Higgs Boson as this is like a central piece linking quarks, leptons and bosons).
