Supernova and spacetime stretching

[Jacques]

Hi

During the core collapse of a massive star does spacetime stretch ?

Is it possible that because of that stretching, some particle get catch in a wave and accelerate to faster than light ?

I know relativity prohibit that matter be accelerated faster than light, but when we consider distant galaxies they look like going faster than light because of the space expansion. Is it possible that something similar happen on a smaler scale in supernova explosion ?

 

Thanks

I think that space time does stretch. Because as a the star collapses, the core gets very dense. thus stretching space time until the dying star explodes in to a supernova.

Yes quite possible. There still exists much mystery around topics of redshift of light, spacetime, blackholes etc..
