By the way, in 2012, scientists on the LHC were able to create the highest man-made temperature, at an astounding 5 trillion K – the temperature of the universe moments after the big bang.
5500C? i thought it’s not that much, chemistry can get you there
apparently not
thermite tops at some 2000C-something, and in any case can’t work above boiling point of aluminum (2470C)
only in few cases of adiabatic flame temperatures reach above 4000C, and all in oxygen. highest listed in wikipedia is oxygen/dicyanoacetylene at 4990C. maybe some wacky highly fluorinated oxidizer will allow for even higher temperatures. adiabatic detonation temperatures also top out at some 4500C even for the most energetic explosives
so really only practical way to get to 5500C is through use of electric arc
Loss and lots of science and math to model and simulate the sun in a variety of ways slowly weeding out the models that weren’t making experimentally validated predictions. I’m not sure how many astronomers are around, especially sun focused ones, on Lemmy to answer you more specifically about the history of sun science.

We should at least have referred to the corona instead of the surface.
When it comes to the opposite, the coldest temperature in the known universe has actually been man-made (also in lab settings).

What if we pre-heat the room to 3000, then very quickly introduce the explosives and run away before detonation?
if there’s no room left after measurement, did it really happen?
You’re only off by about 9 zeros.
Surely a laser would be way more practical
depends on what do you want to heat up. hint: at 5500C you need to handle plasma anyway
How do we know what the layers of the sun and earth are, and how hot they are? What methods were used to gain (or theorize) this information?
