with reference to the article and the vid above i have these points :
1. i don't believe in the existence of "space-time" and other such stuff... they are just human mathematical constructs that have no validity in nature... these particular people talk of "gravitational ripples" taking for granted the existence of "space-time".
2. could the so-called gravitational ripples simply be some kind of gas molecule electrical effect that origined in the unification of the two black holes??
3. is einstein always right??
4. the "listening to universe" thing would simply be attaching a speaker to the photometer assembly and the speaker will simply produce sound based on variation of the electrical input and we interpret this on our terms... this has been done before with the sun and with the earth's rotation i think and also i think with the seti project.
5. most americans are so bad with analogies... i couldn't understand his talk of using ligo to measure distance between the sun and the next star system ( alpha centauri system ).
6. time machine?? really??
no, a collision of two black holes... he says each was of 150 kilometer diameter.
as for big bang, no one knows of its form... it is all guesses, as far as i know.
