This is a question Controversial Beliefs

Some mugs still think the MMR injection gives children autism (it doesn't), while others are of the belief that we're ruled by billionaire lizard people. Tell us about views outside the mainstream which people go glassy eyed if you bang on about them (Your grandad's a racist - no need to tell us, thanks)

I honestly, truly believe in the Half-Life of Sound
It was a theory conceived by Marconi, on his deathbed and probably in the grip of dementia, that Sound never actually dies away, but like radioactive material it just gets less and less without ever disappearing altogether.

The problem is, the theory goes, that we simply don't have the microphone & filtering equipment sensitive enough to pick up, in his example, the Sermon On The Mount.

I know it's probably rubbish, but I do believe it nonetheless, so be careful what you say - that "CHICKEN PISS!!!" you yelled might be heard in 50 generations' time and cause all sorts of trouble. (A bit like that line of Arthur Dent's, about having tremendous difficulty with his lifestyle).

I never met my grandad, but my gran always referred to my sister's boyfriend as "that Jew boy", if that's more the sort of thing.

Nice, but bollocks.

I feel compelled
to whack you with a crowbar.

OK, scratch the "probably" in para 3.

Sorry, I don't have any up to date, pop-culture references.

Half Life, was a popular videogame,
wherein you could hit stuff with a crowbar. The developers, Valve, also created Portal, set within the same continuity, which spawned a meme about cakes.
To be fair, this was a few years back.

Long story short, I mean you no harm.

That's OK, it's aways interesting to find out what codes mean.

You sure your gran wasn't asking a question?

Hur hur! Very Good!
No, being from Notts she'd start every question with "Now then"

"that jew boy".

By a similar token, about 1% of the snow on an un-tuned TV is the energy from the Big Bang.
The problem is to know precisely WHICH 1%...

The physics invovled are not that complex.
As sound attenuates the higher than ambient pressure of the wave crest eventually collides with the lower than ambient pressure of the wave trough, cancelling the wave.
There is a measurable half life in ideal conditions but the remaining sound wave quickly becomes indistinguishable from the background of random molecular motion.

I guess Marconi thought he was covering his arse with the "lack of sufficeintly sensitive equipment" bit
which is perilously close to "you can't prove a negative".

Thanks for the physics though, I know it's a silly theory but somehow the mere idea of sound carrying on comforts me, a bit like how religion works on other feeble-minded people perhaps.

Can't hear you mate.

Why's it a silly theory?

It's not,
it's just that I want to maintain my standing in the scientific community before unveiling my really big theory, the fools.

The physics aren't that complex
but those aren't the physics. How can the crest collide with the trough? The whole point of a wave is that they are going at the same speed. Different waves may move at different speeds in some media, but that's dispersion, which is quite different from dissipation.

It's much simpler than that: friction between air molecules mean that as the sound wave propagates, it continually loses energy to heat and reduces in amplitude.

When you see waves on a beach they all go in the same direction, roughly at right angles
to the coastline but when you look over the side of a ship at sea they're all going in different directions and colliding with each other at various angles.
Who straightens them up and at what distance from the beach does he do it?

My mate Alan works the coast between Morecambe and Fleetwood. I've gone with him on his rounds a couple times. We were a fair distance out when he was straightening the waves, about 10 miles or so I'd reckon.

I like this idea. I'm going to go outside later and shout "PEOPLE OF THE FUTURE ARE ALL BALL BAG CUNTS!" dead loud later, in the hopes than some Star Trek stylee future scientist will one day hear it with his space tricorder or whatever.
