I did Google this a bit and understand that sounds needs a medium to travel.
So if we could hypothetically stand in the surface of the sun would we hear nothing?
If two asteroids collided would it be completely silent?

Correct. There’s nothing for you to hear if you’re in a vacuum, in the same way that you can’t have waves in a pool with no water in it.
Sound is a mechanical wave. It needs something (air, water, etc) to travel through.
Stars do make noise, but we cannot hear it. If you could, the sun would be as loud as a train horn here on earth.
If two astroids collided, it would be silent to an observer, theoretically you could hear/feel it if you were on the astroid.
So, with the understanding that sound is just vibrations in the air, and in a vacuum there is no air, so sound is not possible… However, stars and asteroid collisions do result in the emission of energy, but it can’t be dissipated as sounds, as it might in an atmosphere, instead that energy is emitted as heat/radiation as well as kinetic in the case of collisions
Two asteroids colliding make no sound. But stars have an atmosphere, depending on your definition of the “surface” the sun makes sound.
I believe there is still matter around and eminating from a star, so it could very well have a distinct sound, but if you’re way back looking at it, there is no medium to bring that sound to you. Sound waves are like waves jn the ocean, stand away from the shore and they can’t get to you, and unlike light, we can’t see sound, so you wouldn’t know those waves were ever there unless they could reach you.
You can’t stand on the surface of a star, or a gas giant, because it is gas and too thin. As you go in, you can hear sound, through the gas, just like in Earth’s atmosphere.
>So if we could hypothetically stand in the surface of the sun would we hear nothing?
We’d hear the noise of millions of atomic bombs going off all the time. And the solar wind too for good measure.
Stars are RIDICULOUSLY LOUD, it’s just that over vacuum the only part of that noise that gets to us is the electromagnetic one (light and radiation).
Collisions between asteroids are also very loud… To the asteroids themselves and the parts of them flung off because of the collision. But since there’s no atmosphere around to transmit those vibrations, so long as you’re not touching them it would appear to be silent.
Absence of atmosphere does not mean absence of noise, it just means that noise is not going to be transmitted to things that are not touching the source.
It’s not that there’s no sound in space.. it’s that the sound waves have no medium to transfer and travel to your ears
