Cosmonautics. "Millimetron" - the key of time (2016)

To understand how time works, scientists study gravitational effects using hydrogen frequency standards.

Atomic clocks on spacecraft measure time in space and bring Earth and space time to a single denominator, synchronize.

Soon, the same device will be installed on the Spektr-M spacecraft with the Russian Millimetron space telescope.

The new space observatory will operate in the millimeter wavelength range and will see how stars and exoplanets are formed, and most importantly, will look beyond the event horizon of the black hole in the center of our galaxy.

According to a number of scientists, it is there that, due to the monstrous force of gravity, time goes twice as slowly as on Earth.

The plot starred Sergey Krikalev, Sergey Popov, Charles Bolden, Yuri Kovalev, Anatoly Belov.
