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

Creating a fusion reaction isn’t that hard, it’s containing it that’s the problem. Modern Nuclear bombs main stage is all fusion reaction with a fission reaction to start it. The sun’s mass self contains the reaction in the core.
