They would get burned.
In all probability - not that this scenario would happen - but the resulting combination of masses, would push the combined "stars" over the Chandrasekhar limit and a black hole would form.
stars
Light travels at about 300,000 metres per second. The time taken for that light to reach us would depend on the stars distance.
After about 20 miles, you would reach the mantle.
Solidification
What would happen is that we won't be able to see the stars or see the sunset. We would still be able to sleep I guess but you never know ^_^
That would be a collission between two neutron stars. Since many stars are actually double stars, this can happen now and then.
If there were no gravity, period, there would be no stars. If gravity ceased to work, there would be a whole lot of violent explosions as the nuclear, mechanical and other forces within the stars popped the stellar balloons, so to speak.
If our sun did not exist the other stars would be little different from the way they are. The sun is just one of billions of stars in the galaxy. Many of the stars we see in the sky are larger than our own sun.
They feed on them and then the clams would overpopulate the beds if not eaten.
The volume reach the half.
stars do not contain of minerals. First of all stars of flaming balls of gas and if there were minerals in it, you would not be able to reach them. Some stars are not real theynhave already blown up but you still can see them.
