I have a question... the expression for de brogle wavelength of anything is found by intermixing E=pc and E=hv, that tells that the mass of anything is the measure of less de brogle wavelenth..so as the speed of something increases, its de brogle wavelength decreases and hence mass increases. So, the big bang singularity had no de brogle wavelength.. so what is the point finding a theory connecting GR and QM to explain a singularity ?

why do you say that the singularity had no wavelength ?
anonymous
  • anonymous
exactly as unklerhaukus said, how would you know that big bang singularity had no wavelength every thing exhibits dual nature so would it have too

It had infinite mass, and de brogle wavelength is inversely proportional to mass, so it comes out to be zero.

in the same way, as we tend to understand singularity ?

I've never considered the wave nature of the singularity. In what space would it have done its "waving"? Waves also require the passage of time to undulate. Where was this time? Neat question nkamran......

. Do you not know that all known physics 'break down' at a singularity? U+E=0

singularity is the physicists way of saying "i have no clue what the heck it is" :P..

my point here is that why are people in search for a theory of quantum gravity ? what is the reason ? there is no wave nature, no probability of anything else to happen, ...infinitely high temperature...etc...

what you mean there is no wave nature?! :O

no de brogle wavelength associated...

My understanding is that a theory of quantum gravity would allow are understanding to be pushed back closer to the singularity than we can do now. It's worth pursuing because it extends our knowledge, not because it resolves all the questions.

i think the idea of assuming a wavelength or whatever to the singuarity is itself meaningless...

Singularities arise from formalisms that are used to explain various phenomena. They are not intentionally introduced. They are undesirable physically. There is a belief that singularities indicate a weakness of a theory. Physicists are now trying to quantize space so that one two objects can't get too close.

hmm...that is a nice answer, others were just repeating the question..I already know that a wavelength associated with singularity is meaningless, I wanted to know the answer that quantum gravity would provide, this answer and the one given by creativespeller make sense
