NASA | Afterschool Universe: Supernova Can Crunch

you guys should make NASA food channel too.

o my god a ginger!!!

[sano0311]

and we already have world of Warcraft heroes disapproving the science....perhaps if the lady compared the experiments to "zits" instead of "fusion" it would be little more familiar???

[changbroot]

This is not correct, because this demonstration is sudden, while the "fuel/fussion," in a star is slow which allows equilibrium to reach slowly. Also, at such EXTREME temperature, there is no molecule, and atoms don't even exist as we know it, because electrons move freely. Those things or "supernovas," are not yet truly understood. We don't even know if the universe or our "sophisticated," scopes plays tricks on us or not. To conclude complete understanding of outer space is foolish.

How do the Periodic Elements Table come from? I mean, stars begin whit hidrogen and supernovas end up whith an iron core, but what about the others elements, i. e. argon, etc.

Thanks and regards.

@rottencranberry Stars fuse elements up to iron and many elements are created only during supernova explosions, like fluorine or uranium for example.

what happens when star collapses? does super nova occur? does it become a black hole? does it become a dwarf star or a newtron star? help anyone!!!

[4FunPlayin]

@FurkanKhan100 If it 'collapse' most likely a black hole will come as a result.

[4FunPlayin]

@FurkanKhan100 I take that back (what I wrote before)

If the star is really big a black hole will come as a result.

[Shift4chizzle]

@FurkanKhan100 i think when the center of two galaxies collide it creates a black hole, someone correct me if im wrong

[AlphaCrucis]

@Shift4chizzle Galaxies have black holes at their center, but this doesn't come about due to galactic collisions. So your last comment isn't correct, but your other two are correct, even if a little rough. ;)

[Shift4chizzle]

@AlphaCrucis lol ok thanks, cos i watched a video from this channel a long time ago i think i jst got muddled up, cos it said somehting like that

[AlphaCrucis]

@FurkanKhan100 It depends on the type of star, especially it's mass.

[Tripside007]

@FurkanKhan100 Roughly, when a star dies, several things can happen depending mostly on the star's mass. Supernovas only occur on stars that have at least 8x the mass of our sun, after that, it can still turn into several things, one being a black hole, also depending on the mass of the original star, which should have to be around 50x the mass of our sun, (correct me if I'm not wrong - not sure about this last value).

cool

[mrteemumilto]

0:19 I don't the way she looks at me. Kind of imposing and serious.

[khunopie]

i gots me a edumacated

[xxxhkh117xxx]

oh, i always thought gravity is acting from the core.

[gustavo87467357]

@xxxhkh117xxx nope, it's acting TOWARDS the core

[Triglavus]

One of the coolest things I´ve ever seen!

This is how you teach kids!

[AnotherPostcard]

First!

The more you know!
