Evidence of Gravity Waves

March 17th, 2014 by G.

The boffins say good ol’ Earth is cruising through gravity waves. Good thing the Woosters are famously good sailors, or else a chap could get a touch of mal de mer, what?

Back in the 1990s I did a bit of newspaper journalism, and wrote a piece on Gravity waves for the Glasgow Herald – having interviewed the ‘group’ of physicists working on the problem at Glasgow University. I wasn’t impressed – not because I disbelieve in gravity waves, but because the main activity of these researchers was trying to get heaps of government money to fund a vast engineering project to build a detector to find what they already knew was there. Not what I think of as doing science.

While I am not entralled by the idea of working most of my time just to get funding, the truth is, we have predictions of gravity waves, so we knew they were supposed to be there, but we had not detected actual waves yet. Sometimes our predictions are right, but sometimes they are just wrong, and we don’t know which is which, unless we look.

I am a bit puzzled by my own reaction to this, which was a kind of “Meh.” I should be excited, but for some reason I’m not.

Perhaps I was hoping for a direct detection rather than this rather indirect detection by imprinting on the cosmic microwave background.

If you can come up with a method of direct detection, you’ll probably get a Nobel prize in Physics…

Agreed, h_nu. Kind of my point. LIGO would have won Kip Thorne the Nobel Prize if they’d actually achieved a detection.
