  What will happen if a ball of ice with the mass of sun is thrown into the sun?

+ 0 like - 2 dislike

The question is a bit unrealistic with its circumstances but lets assume there is a bucket of ice cooled down to about absolute zero and is about 1000 km away (all around the sun) from sun and moving with v_0 = 100km/sec, what will be if that all water with mass of sun reaches the sun.


Basically I have read about this in gizmodo http://gizmodo.com/could-the-sun-be-extinguished-by-a-bucket-of-water-just-1669914928 but did not agreed , thats why I have decided to ask about this phenomena here, hoping to find out more precise answer

Closed as per community consensus as the post is low level, unclear, and unspecific

Ofcourse the problem is quite hard and would require a lot of computer simulations among other things. I personally won't be able to say anything about this subject.

However the analysis in gizmodo appears to be fairly reasonable.

Maybe if you pointed about what you disagreed with maybe we can talk about it.

Ice or water should matter little because everything will ionize due to gravitational energy anyways.

@Prathyush Thats why I mentioned that hypotetically the motion starts very close to the sun, if we consider the ice travels long and transform its potential energy to kinetic, in that case I agree with you. But lets consider the startpoint is very close to the sun, in that case shouldn't the ice melt down the star outer layers ?

Voting to close as low level, unclear, and unspecific: http://physicsoverflow.org/30932

@atadevos As the article in Gizmodo mentions you have to look at the Gravitational potential energy as the particle travels falls into the center of the sun.

What do you mean melt down the stars outer layers? Do you mean melt down at the stars outer layers? In any case it would ionize.

@dimension10 This question is neither unclear, nor low level nor unspecific. It is however not an interesting question from the point of view of learning about new physics.
