How Do Gravitational Waves Really Work?
A couple weeks ago, astronomers announced they had detected gravitational waves from a "kilonova" (I hate that name but we'll wait for another blog post to explain why).
A few weeks before that, the Nobel Prize was awarded for the work that went into LIGO, the gravitational wave observatory.
So gravitational waves — ripples in the fabric of space-time — are a big deal in the world of science. But how, exactly, do they work — and how, exactly, can you learn about them in under four minutes?
