It’s not often that physics makes front page news, but it did today because, for the first time ever, scientists have been able to confirm the existence of gravitational waves.
This discovery represents the final confirmation of Einstein’s theory of relativity, which is a big deal.
While we understand the gravity of all of this, the actual science behind it… not so much.
This morning we put a call for help out into the cosmos and, happily, the universe provided answers straight from the mouth of our favourite astronomer Dr. Alan Duffy.
Here’s what he had to say when he, very obligingly, answered my terrible questions.
So, what the hell is a gravitational wave?
A gravitational wave is the final prediction of Einstein’s theory of relativity.
Basically, it is that the space and time that we move in, that we experience, actually ripples.
Think about this: If you throw a rock into a lake you get ripples coming up on the surface of the water.
If you get two really massive objects, like black holes, coming together you’ll get similar ripples across space and time.
Two black holes colliding, eh? That sounds… unlikely, is it?
We know that black holes collide all the time and these collisions are big enough to see these ripples for millions of light years.
What’s surprising is that that just a few days after our newly upgraded technology had actually turned on, these ripples hit us it was.

The sad thing is that the majority of the population will be more impressed with a meathead that can put a ball over a line or a faux personality with a prominent posterior
I'm releasing my inner nerd after reading about this as a layman for years - I need a cold shower.
