Do sound waves travel thru space?

If so, will galaxies far, far away pick up the
Beatles?..............somebody out there should be picking up "I Want
To Hold Your Hand" about now.

No, soundwaves don't travel through space: that takes an atmosphere. But
radio waves do, although I would think - at the distance of the nearest
galaxy, those waves wouldn't really be carrying much in the way of
distinct information. For that, the signal would need to be transmitted
upon a laser.

Heh. This thread instantly put that line in my head, too.

Yeah... other galaxies, no, you're probably right about that. But other
solar systems in our own galaxy, possibly. I think some people get those two
things mixed up.
There hasn't been nearly enough time for our earliest signals to travel to
other galaxies, anyway. I think the closest galaxy is about 70,000 light
years away. So, it'll be awhile...

I heard that I Love Lucy is #1 on the Neilsens on Jupiter.

And I hear Saturn has passed a law banning "eye-o-vision" since they
started receiving The O'Reilly Factor...

Sound waves no. Radio waves yes (see SETI.)

I agree...sound, no...Radio, yes.
There have been a couple (?) of very funny movies based on the premise of
distant alien civilizations viewing or listening to our 'radio waves'... I
seem to recall one in which their whole understanding of us is based on one
sitcom (?). And another that based *IT'S* whole civilization around an
episode or two...!?! Sorry, I can't remember exactly which it was...but I
remember laughing.

In the movie "Starman", Jeff Bridges plays an alien who intercepts the
Voyager Spacecraft and travels to Earth with all his knowledge of
humans coming from the Phonograph Record onboard. There's a great
scene when he first appears -- naked -- after first landing, and
encounters a startled female. His first words are "I Can't Get No
Satisfaction". (Poetic license, of course, since that Rolling Stones
song was NOT on the actual Voyager disc -- but very funny anyway!)

LOL!!! That is very funny...I don't remember that...I will watch again.

Not sure but I think sound is different from light in that it travels
by air particle movement into the ear. So space having no air would not
carry it. Radio waves before converted to sound maybe.

kinda what I was thinking...................scientists out there?
|
Sean Carroll...

Correct. Sound waves cannot exist without a material medium, such as air
or water, to carry them. Radio waves, however, are part of the
electromagnetic spectrum and thus all things that have been broadcast on
the radio or TV are leaking out into space for anyone to receive. The

Thank you Sir...I haven't seen EXPLORERS, but I did see GALAXY QUEST. For
some reason though, I still think there are one or two more that I seem to
remember...I just can't recall them.

Sound travels by gas or air movement. That's how woofers work. But

Sound waves travel faster in liquids.

plenty of radio stations were transmitting signals that sent the tunes
by 1963. The first airings of I Love Lucy have just made it to the edge
of our solar system.

Oh they're much further away than that. Radio waves travel at the speed of
light. However many years ago they were first transmitted is how many light
years they'd have traveled by now.
So anything transmitted in 1963 is now 43 light years... far, far beyond our
own solar system. Alpha Centauri, our closest neighboring star, is only
about 4 light years away. So "I Love Lucy" is old news... they've been

Yes of course, I mentioned Alpha Centauri elsewhere already.
Sean Carroll...

Alpha Centauri (proper name Rigil Kentaurus) is actually a system of
three stars. The nearest to us is Proxima Centauri, 4,26 light-years
away. Alpha Centauri A and Alpha Centauri B are 4,39 light-years away.
(Pardon my decimal commas -- I do it the European way because I think
it's too easy to accidentally overlook a simple dot.)
Other solar systems in our galaxy *are* the correct thing to look at.
Other galaxies are so far away they're hardly in the same universe as
far as we're concerned in any practical way, at least for the next
thousand years. Even all the star systems and empires in Star Trek are
only supposed to take up *part* of our one galaxy.

Man, it just bends the imagination. As my dad used to say, what's all that

out there for?

To prove to us that we scarcely count except to ourselves, our dogs, and
the bacteria in our digestive systems.

You may be thinking of the Voyager 1 spacecraft, which only recently left
the outer reaches of our solar system.

Lucy. In the sky. with DIAMONDS!
Heard it, wept. Whatever possessed him to attempt this song?

Not really your anus cause that probably has already been rocked. : )

very first radio signals human beings ever sent out, back in the 1870s,
now define a sphere around Earth that extends out about 130 light-years
in every direction. The first Beatles songs right now are only about
43 light-years out.
The nearest star other than the Sun, Proxima Centauri, is a little under
four and a quarter light-years away. The centre of the galaxy is about
26 000 light-years away.

No fun i know.
I'm sure they're downloading the mp3s through secret remote alien means.

Maybe people on other planets don't have any hands..in which case...the
song would mean
nothing to aliens. LOL
Dale Houstman...

Heh. Of course, it is more than highly probable that any alien species
which achieved our [so-called] level of intelligence would indeed have
hands, although not necessarily five digits, because the development of
intelligence presupposes a certain ability to manipulate [in the real
meaning of the word] one's surroundings in a relatively sophisticated
manner. Thus - although I am not convinced the universe is as filled
with human-level intelligences (if any) - I do think that if we do ever
come across one they won't be Einsteinian jellyfish or Aristotleian
fungi. The real problem (of course) will be purely a matter of
translation. This is where images would be of great help.
