    Star Supernova
AI Thread Summary
Stopping a star from going supernova is not feasible through external gravitational forces, as a uniform spherical shell of mass has no effect on the gravitational field within. The gravitational collapse of a star is driven by its own mass and internal processes, which cannot be countered by surrounding massive bodies. If a star were near a single massive object, such as a black hole, it could experience tidal forces instead of collapsing. The discussion highlights the limitations of external gravitational influence on stellar dynamics. Ultimately, the concept of halting a supernova remains theoretical and unsupported by current astrophysical understanding.

hi guys, my first post...

i was wondering if there is anyway of stopping a star from going supernova...
my proposal is as follows:

if you where to have a star about to go supernova, (as a result of lack of fusion) in the middle of space, and then you had super massive bodies surrounding the star equally in all directions, would that be able to stop the star from collapsing in on itself, and in turn stopping it from going supernova? also assuming that the net gravitational force of these external bodies attracting the star match the gravitational force that is making the star collapse in on itself.

thanks!

Hi gtriafylos, welcome to PF.

A uniform spherical shell of mass will have exactly zero effect on the gravitational field within.

Have a look here for more details:

If it were orbiting a single massive object like a black hole, it might get torn apart by tidal forces instead of collapsing. (How did it become a star in the first place though...?)
 
Ahh ok i see, thanks Bandersnatch. it would have been pretty cool if it worked though!
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
