But, like, it's only gravity waves the Silver Surfer rides, right?

Yeah but it's a bugger wedging the Earth into the back of a Vauxhall Nova...

it's a good thing you don't make your living using arithmetic: a period of 278 hours is a frequency of about 1 microhz. A frequency of 100-5000 microhz is period of from 3 minutes to 3 hours

I believe there are people in Arizona who may be listening to the Harmonies of these vibrations, they think it is a paranormal phenomena but perhaps it is not. They can't seem to find the source of the "Hum". Maybe we have a Humdinger here.

only reverse it, I for one would be quite happy to wedge a or even several Vauxhall Nova's into the Earth, preferably with a few chav's still inside it.

"g-mode vibrations are not optically detectable. But the evidence of the waves is there, and easily detectable, in data on Earth"
Really? I watched Cosmos on BBC2 last night, and there has been built a massive thing to detect gravity waves, which are so weak it is easier to detect a (sea) wave hitting a beach 6 miles away.
They are hoping to detect one in about 2012

You are confusing gravity waves with gravitational waves. Gravitational waves are produced by large (several solar masses) being accelerated to relativistic speeds and it is *hoped* they will be detected from neutron star, coalescing binaries, black hoes and a few other literally cosmic events.
I'm not sure what gravity waves are but they are a different phenomena.

Are we allowed to say "black hoes" on this website? I also saw the programme on BBC2 last night and think they said 2015.

So THAT's what the Preview Comment button is for!
BTW, a quick look at Wikipedia does mention that the terms 'gravity waves' and 'gravitational waves' are often used (incorrectly) interchangeably and gives a good description of both.
I didn't see the BBC2 programme but 2015 sounds like the timeframe for LISA (a space-based detector). I believe that the UK-German GEO600 and US LIGO ground-based detectors are approaching operational sensitivity at present.

I think it's more likely to be a bunch of nuts with tinitus. :)
