Well, you're the expert sensei ... don't let it take up too much of your time, i bet you have like a stack of paper on your desk by the time you get back.

Every answer comes with tenfold questionmarks attached, right . I've always been a bit confused on expanding universe versus black holes drawing everything inward ... shouldn't they , in the end consume it all ?

i mean the more massive one gets as it gobbles up more matter/energy, the further it reaches so the more it can eat as a consequence. Would that be possible that in the end the universe would "breathe in" again , come all together into the biggest supermassive dense object , which in turn
(heh)
implodes on itself to create, what's that called
a singularity ? (the lingo isnt my forte) which leads to a big bang and the circle is round (pardon the philosophy its about 4am lol)

always a pleasure
