Thank you

Remember that there is, are, Microbial Life forms in the very Deep parts of the Oceans that withstand tremendous pressure and HEAT
Sorry your right on two,matthyaouw said:The sun won't go supernova, it will go red giant, and it will be 5 billion, not 5 million years.
I doubt that any microbial life could survive when it happens, as the ocean would evaporate completely.
Correct me if I'm wrong (I was once in 1986, so I'm overdue for a repeat), but white dwarfs only go nova when they are part of a binary system and are having hydrogen dumped on them by their expanding partner. The sun will not go nova. It will expand into a red giant, then shrink to a white dwarf. End of tale. Also, if recent calculations haven't been overturned yet again, then red giants are not as big as we thought and the sun won't engulf the Earth in that phase, just give it a rather good toasting.matthyaouw said:Only stars quite a lot larger than our sun go super nova. A white dwarf (which our sun will eventually become, long after it begins its red giant phase) may pass through a nova phase, but that is different to a supernova.
One for two, yes to the first part, no to the second part, better be updating yourself (1986 to 2005) for the next time, me too.Ophiolite said:Correct me if I'm wrong (I was once in 1986, so I'm overdue for a repeat), but white dwarfs only go nova when they are part of a binary system and are having hydrogen dumped on them by their expanding partner.
