7 mind-blowing facts about gravitational waves, the 100-year-old prediction just confirmed by scientists (PHOTO)

7 mind-blowing facts about gravitational waves, the 100-year-old prediction just confirmed by scientists (PHOTO)On Thursday, a team of scientists announced that they had detected a phenomenon called gravitational waves for the first time.

Rumors are circulating that the discovery is worthy of the prestigious Nobel Prize in Physics because it gives humans a new way to study our universe.

These waves are ripples that contract and expand the space-time around them. Scientists detected them by measuring this distortion as one of these waves passed through Earth using the advanced Laser Interferometer Gravitational-Wave Observatory (LIGO).

But doing so was extremely difficult, and what scientists discovered upon detecting these waves was nothing short of extraordinary. Check out some mind-boggling facts about them and this latest discovery:

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 his theory.

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.

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

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

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 them, too. But those waves carry 100 billion times less energy than two merging black holes, making it impossible to detect with current technology.

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

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 new behavior in the cosmos that we never knew existed before.
