Can sounds from the past be heard from space just as we can see light from distant galaxies?

Sounds cannot be heard in space to begin with, so hearing any from anny time is impossible.
Secondly, the energy in a mechanical wave such as sound is dispersed and transformed as the wave travels. After a while all of this energy is turned to heat, and the wave ceases to exist, so even if sound travelled through space, we would not hear it after only a few hours, let alone years or centuries as with light.

Why do scientist study the light coming from distant galaxies?
They study distant galaxies because they want to know whats out in other galaxies and how many planets it has
The fact that the light from distant galaxies is red-shifted suggests that the galaxies are?
Moving away from us
How does light from distant galaxy . galaxy out side of 32000000 light years support the big bang theory?
The light from distant galaxies is redshifted. The only reasonable explanation for that is that the galaxies are moving away from us.
How far away are the most distant galaxies?
That is impossible to answer because scientist don't know ALL the galaxies.
When viewed from earth the light from very distant galaxies shows a red shift evidence that these distant galaxies moving towards or away from earth?
The "redshift" refers to the fact that the light is less energetic than when it was emitted; it shows that the galaxies move away from us. Should a galaxy move towards us - which is possible only for galaxies that are relatively close to us - then there would be a blueshift.
When the ultraviolet light from hot stars in very distant galaxies finally reaches us what form does it reach the Earth in?
visible light
What is The bending of light due to the great mass of distant galaxies?
The bending of light due to great masses is called Gravitational MicroLensing.
Does gravitational lensing magnify distant galaxies at distances up to 13 billion light years behind galaxy clusters?
Yes. Lensing magnifies the image of galaxies behind distant galaxy clusters but also greatly distorts the image.
Does light does not require matter to move through?
It doesn't. Light comes to us from the Sun, and from distant stars and galaxies, through what is basically empty space.
Telescopes are placed in space to view distant galaxies primarily to?
aviod the absorption of the light or other radiations in the atmosphere of earth
When scientists look at very distant galaxies through powerful telescopes they see the galaxies as they were millions or billions of year ago Why is this?
The vast distances involved means that the light we see left those galaxies a long time ago.
