Without the Moon, marine life will die out on Earth
If the Earth's satellite disappears, most likely, a global catastrophe will not happen. Once it was the main source of light in the dark - now people know how to do without it. And yet, some major changes will occur. For example, many water sports will come to an end. The phases of the moon affect the waves - passing over the surface of our planet, it "pulls" masses of water along with it.In addition, marine life will die out, whose life is directly related to the tides. Without a satellite, there will be no solar and lunar eclipses on Earth, and the tectonic plates will shift, causing earthquakes and volcanic eruptions. But the main thing is that the planet's climate will no longer be the same.

Silence reigns in space
The quietest place on our planet is considered to be an anechoic chamber at the Orfield Laboratory - it absorbs up to 99.99% of sounds. But even there you will not be able to hear absolute silence. It will disrupt the work of our lungs and circulatory system. Today, various studies are carried out in this laboratory and devices are tested. And in such isolated spaces, NASA specialists test future astronauts.There is no sound in space because there is no air. Therefore, even powerful galactic explosions occur in complete silence. It is very difficult to work in such conditions: just a few minutes in a sound vacuum cause panic attacks and severe auditory hallucinations in unprepared people.
