Hold onto your hats, space watchers, because this news is HUGE. Scientists have detected gravitational waves for the first time -- ripples in spacetime that back up Einstein's work and let us eavesdrop on cosmological chaos.
We now have the ability to listen in on the most violent events in our cosmos. Thank you Einstein!
Detection of gravitational waves from colliding black holes has been confirmed, proving a critical Einstein theory.
The reason is the sun, moon and Earth don’t move to the tune of simple arithmetic.
What are they? Why are they important? Why should we care?
