Sound travels by vibrating whats in the air... this is why u can hear sound through walls.. walls can vibrate as well...

Problem with space is .. its empty and nothing to vibrate.

If ships fire projectile ammo, you will hear from inside the ship as friction generates sound. The ship that got hit by projectile ammo also will hear the explosion inside the ship.

As with movies, audiences don't want to sit through silent movie while watching the battle in space. So movie makers have to add sound in space so that audiences will get excited watching the scene.

Ya exactly. Most airports have glass and middle insulation is that is so thick, that sound can't vibrate it nearly enough for it to pass through, hence you barely hear a 747 or 777 taking off even when the runway is pretty close by

what about black holes? ive read somewhere that they are faster than light because light cant escape a black hole.

in the practical sense there is nothing that can go faster than light in a vacuum.

however there are some very unique cases where scientists have made light travel faster than the speed of light however no information was transferred in the process.

i dnt know the too much about the details in these cases

Isnt it also true that the faster you travel, the slower time flows relative to you, and if you reach the speed of light, time stops.

As for the black whole, the reason light cannot escape it is because its gravitational pull is so massive, it actually pulls light back down, just like Earth does with us.

earlier a post said light is made up of photons with no mass, how does gravity pull on something with no mass?

gravity can bend light in a vacuum so gravity can pull light in a vacuum that is unless light has a terminal velocity in a vacuum
hang on im thinking, ouch brain strain

because gravity isnt pulling on the photon, its pulling or "bending" the space around the area. anything that falls within that space gets pulled on regardless of its own characteristics

photons travel through space, and a black hole bends space so greatly that anything that crosses its event horizon (the point where gravity grabs u and u cant escape) it automatically gets sucked in

the thing about gravity is, it isnt something tangible even on a quantum scale. gravity is the result of space bending. it isnt something we can capture, thats why it affects everything. of all the forces in nature, gravity is the only one that acts as such. any and everything else can be altered but gravity is always constant given the mass, volume and density of an object. thats why it doesnt have to "pull" on a photon, it simply bends the space around the photon and the photon goes where the space bends the most. a black hole bends space the most

@below

ur link doesnt work, but what about them? in fact Gravitional lenses help prove my point. Those are used to detect gravity's affect on light coming in form distant galaxies

your thought process.. i love it
