Absolutely no sound?

[lukeclooney]

i would love this game to have some music to entertain me while im making a massive star collide with a billion galaxies... or atleast some sound like a pop when a planet collides or an explosion sound when you click explosion

There's no sound in space.

There's no sound in space.

YOU TELL HIM!

But seriously, there is no sound in space, therefore, never add sound (other than music) to a space simulator.

wait maybe i'm wrong, but aren't there atleast miniscule amounts of gases in space?
That would allow an infinitestimal amount of sound to travel? maybe? lol

No. The space between the molecules is too far.

[vh]

hmm
well on average there is over a million hydrogen atoms per cubic meter
probably a very low chance of sound
but not zero?
amirite
i mean suppose they all lined up perfectly and the sound went into your ear!
TADA!

[deoxy99]

Nope, it's nearly a vacuum. One atom maybe per 1 mile?

[vh]

no
thats more like intergalactic space
where the average is less than an atom per cubic meter
but intersteller? 10^6
and interplanetary is probably several orders of magnitude higher

[deoxy99]

Alright, it's hydrogen for crying out loud, it's very hard for sound to traverse it.

Wait wait, if you want to get really scientific, it is NOT a vacuum, it is nearly filled.  Why? Higgs bosons, get it right damn it!

[vh]

oh
but they don't block or transmit sound
so we're going to ignore them for this purpose
it is probably hard to transmit sound through hydrogen
but not impossible! its not impossible!

While sound waves cannot travel in space, I do expect to add sounds to an upcoming version of Universe Sandbox.

In addition to simple UI sounds, I may add (but don't consider this a promise) a "Hollywood" fantasy sound mode. While on the schedule, the release with sounds is months from completion.

Generally it's 1 hydrogen atom per cubic meter. If you had one atom every mile... then you have a bit of a problem with transferring that to 3 dimensions there.

[vh]

thats in intergalactic space though
depends on where
a dense cloud of stellar dust might have up to 10^14 hydrogen atoms/ m^3 so it depends
