Thursday Scientists has announced to have 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 in a completely new way to study our universe. Check out seven amazing facts about these waves and this latest discovery, as reports Times of India:
1. Gravitational waves were first predicted by Albert Einstein 100 years ago. It has taken that long for our technology to catch up with its brilliance and confirm the theory.
2. Scientists suspect that the merger of two black holes emit more energy in the form of gravitational waves in the last minutes before they hit 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. LIGO instruments (shown below) are designed to detect a distortion that is 1 million times smaller than the width of a hydrogen atom.
4. allow us to detect gravitational waves – for the first time – when two black holes are about to collide. The signal LIGO scientists discovered such collision, released 50 times more energy in the form of gravitational waves that all the energy released by all the stars in the universe together!
5. But it is not just black holes that emit gravitational waves – is either orbiting bodies. That means the Sun and Earth also emit gravitational waves. But these waves carry 100 billion times less energy than the merger of two 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 can now detect!
7. Before the first detection of gravitational waves, which had no way of knowing if black holes could merge. So this discovery is not limited to confirm Einstein’s prediction. Also it reveals a brand new behavior in the cosmos that I never knew existed before.
