Scientists say that they have found evidence for gravitational waves for the first time ever. The discovery was made by group of instructors called the LIGO and if it’s true it marks with the biggest scientific finds in decades.
Gravitational waves-The Update:-
- Gravitational waves are considered as Ripples in Space-Time. What is SpaceTime??
- Let’s consider with an example- A small object on the blanket surface which does not change the shape over that much.
- If we place a bigger object with more mass on the blanket surface, then the smaller one will revolve over the bigger one much more significantly and affects other passing objects.
- This is how gravity works in our universe. Objects seem to be attracted to each other but, really they fall the curvature of SpaceTime created by the presence of other objects.
- LIGO observations picked up the wave signals from the two black holes that were merging 1.3 billion years ago. The black holes spun around each other before merging in a massive explosion. This process thus generates huge gravitational waves.
- Albert Einstein in 1918, as a part of his theory of general relativity predicted Gravitational waves. Black holes and neutron stars when seen by modern telescopes produced gravitational waves.
- Scientists would explain how the objects manipulate gravity, and lead to the discovery of new objects.
- Earlier, Scientists have been proved wrong about the gravitational waves. Assuming today finding it right Scientists have proved Einstein’s 100 years old prediction and thus detected gravitational waves.
- The tools that are used by LIGO are very susceptible to interference, which directly means that today’s results could be influenced on Earth.
- LIGO has observations in Louisiana and Washington State, each facility shaped like a giant “L” known as arms stretching 2.5 miles long, vacuum-sealed tubes with mirrors at each end.
- The mirrors measure how gravitational waves warp space-time. When wave passes the mirror gets closer while the other retreat.
