Worthy of discussion in this thread is the role of “dark” matter and energy. Both are clearly mysterious at the moment.
"dark" matter = evil
"light" energy = good
No mystery...it's that simple!
Yes. According to the "End of Time" video I saw recently, the universal doom is scheduled to occur in a Google or so.
I thought it was googolplex.
Where did this "giant star" come from? Where did all iron, silicon, copper, nickel, carbon, etc., along with the lighter hydrogen and helium atoms that comprised this giant star come from?

Nucleosynthesis.
Neutron star mergers and collisions are also responsible for many heavy elements, via the r-process ("r" stands for "rapid"). Neutron stars are extremely dense remnants of supernovae, and as their name suggests, they consist of a complex state of matter, predominantly made of tightly packed neutrons. When two such dense stars collide, a large amount of neutron-rich matter may be ejected at extremely high temperatures and under exotic conditions, and heavy elements may form as the ejecta begins to cool. In 2017, the merger of GW170817 led to the detection of substantial signatures of gold, platinum and other heavy elements over an extended period.

Other stars. We're all stardust.
