Why is the sun able to undergo fusion so easily, compared to us?

Question

I’ve read maybe it has something to do with gravity…? But we have gravity here on earth too.

And while the sun’s internal temperature is around 15M degrees celsius, apparently for us to replicate the fusion effect here on Earth, we need to superheat atoms to 100M degrees celsius. Why the difference?

Answer 1

My goddamn mind is blown. Stars are bad at fusion. Jeeeezus, THIS is the sort of shit my daughter should be learning in high school astronomy, not watching Interstellar like it’s a documentary.
