The statement about particle colliders is not really correct. The relativistic heavy ion collider, where I used to work, is about 2.4 miles in circumference, and reaches temperatures in the 10s of trillions of degrees in its collisions. This is > 1000 times hotter than a supernova. The environment in these collisions is made to reproduce the state of the universe fractions of a second after the Big Bang, and aren’t really comparable to any normal stellar activity.
- bell-cot 4y agoAny thought on what sort of hardware would actually be necessary to reproduce the temperatures / pressures / densities of a sleepy little 1.4 solar mass red supergiant pre-supernova iron core, for a full 10e-12 seconds, in the full volume of a visible speck of dust? (At least in Wikipedia's version of things, the temperature inside a nice, fresh hot-off-the-Collapse'O'Matic-grill neutron star is "from around 10e11 to 10e12 kelvins". Not quite your comfort zone, but far closer:)
