"Space": running on the waves of gravity

A hundred years ago, an inquisitive mind of a genius, Albert Einstein assumed that the universe is filled with gravitational waves, and even described their properties. To this day, scientists continue to look for them. The "Space" invites viewers to witness these searches in Hanover, Germany.

Thus, all objects of the universe - colliding black holes, collapsing stars, planets - create ripples in the fabric of space-time, slightly distorting, deforming it. This "ripple" is the gravitational waves. 

Top 7 striking facts about time

1. Once a year on Earth lasted 486 days, it was about 800 million years ago, before the birth of ancient life in the era of large-scale glaciation of the Earth. Hundreds of millions of years later, in the era of the dinosaurs, the year was reduced to 370 days. He is now, as you know, is 365 days. What is happening? The facts that the Earth rotates more slowly, because it "slows down" lunar gravity.
