How does a supernova explode?

The explosion of very massive stars as supernovae enriches the interstellar medium with chemical elements synthesized by nuclear fusion, while giving birth to a neutron star or a black hole by the collapse of the stellar core.
The transition between the collapse of the core and the ejection of the stellar envelope is a challenge for the theoretical understanding of supernovae.
A hydraulic experiment designed and built at CEA made it possible to reproduce by analogy one of the phenomena of hydrodynamic instability which facilitates the explosion.
This experimental approach is complementary to numerical simulations.
Discover this experiment in this animation.
This animated film was produced and co-funded by the CEA and the ERC, and directed by Studio Animea.

Phenomenal video and presentation!

[@robynsnest8668]

Beautiful and concise. Might want a different color text in spots as hard to see. Well done video!

[@GustavoValdiviesso]

Beautiful. I will use this in the classroom, for sure.

[@cryostratos5359]

Absolutely stunning. The best, the most encompassing representation of the process. Phenomenal. Fantastic work and presentation.

[@freyathewanderer6359]

Interesting and informative - in any language.

[@kin0cho]

Excellent presentation!! Wish the "decisive moment" @3:37 can be explained in more detail.

[@poobertop]

Can someone please point to the water simulation demonstration used at the beginning and end of this video. 5:39

[@CHEIKH_DJIBRIL_DIA]

Intéressant

[@mellamopepe619]

Tres bien

Pourquoi avoir reposté la vidéo ?
L'ancienne que vous avez posté il y a 1 semaine est toujours en ligne : "[Comment ça marche ?] Comment explose une étoile en supernova ?"
Je ne comprends pas.

they implode

Why does a Supernova explode rather than collapse consistently into a so-called "black hole"? If the author has explained it, please forgive me for my ignorance and lack of knowledge of French. I'm not too good with English either. :O/ Anyway, I want an answer. :O)
