Hi everyone,
This may be a really simple one for most of you but I got to start somewhere..
When a ray of light approaches a black hole, is it really slowed down for it to curve from its previous path and enter it.. or does it speed up according to general gravity considerations (of two entities coming closer..).
(I am not skipping the fact that "general gravity considerations" can't be made on stellar bodies and photons.. I actually mean taking into account the mass of the black hole and the factor hf/c^2 where f is the frequency,for the "photon wave").
If I stick to the latter possibility, won't it make it difficult for light to be "absorbed" into the black hole?
Will someone please tell me about 'tachyons' (enrich my extremely feeble knowledge reserve about them...)?
