1. Gravitational waves were first predicted by Albert Einstein 100 years ago. It's taken that long for our technology to catch up to his brilliance and confirm the theory.

2. Scientists suspect that two merging black holes emit more energy in the form of gravitational waves in the last few minutes before they collide than a single star emits over billions of years.

3. Gravitational waves contract and expand the fabric of space-time, but only by a very small amount. The LIGO instruments (one shown below) are designed to detect a distortion that is 1 million times smaller than the width of a hydrogen atom.

4. Gravitational waves allow us to detect — for the first time — when two black holes are about to collide. The signal that LIGO scientists discovered from such a collision, released 50 times more energy in the form of gravitational waves than all of the power put out by all of the stars in the universe put together!

5. But it's not just black holes that emit gravitational waves — it's any two bodies in orbit. That means the Sun and Earth emit gravitational waves too. But those waves carry 100 billion times less energy than two merging black holes, making it impossible to detect with current technology.

6.Scientists also estimate that two black holes merge somewhere in the universe once every 15 minutes. That's a lot of gravitational waves that we can now detect!

7. Before the first detection of gravitational waves, we had no way of knowing if black holes could merge. So this discovery doesn't just confirm Einstein's prediction. It also reveals a brand new behavior in the cosmos that we never knew existed before.

So MORE energy is put into of the universe every 15 minutes by black holes
than is put into the universe by all the stars combined
so black holes are actually converting mass(stars, dust, etc) into expanding space
so here we have the source of "dark energy"!!!!!!!!!!!!!!!!!!!!!

does "space" when it expands become "more space" or just "thinner space"

if all that energy isn't converted to space, where does it go
does it convert to matter, dark matter, CMBR?
