13 Facts That Prove We Really Know Nothing About the Universe

The rings and satellites of Saturn are younger than the dinosaurs.

Saturn has 62 satellites and several rings. Recent data suggests that the planet’s ring formations did not form at the same time as the planet itself (around 4 billion years ago). Computer modeling indicates that most of the gas giant’s satellites and all of its rings appeared comparatively recently, when the dinosaurs still roamed Earth.

The Solar System might yet turn out to have a ninth planet.

Mathematical modeling indicates that the Solar System might have a ninth planet that is 20 times further from the Sun than Neptune. It is believed that it may be 10 times the mass of Earth. It will only receive a name if its existence is confirmed.

There are no less than 15,000 large asteroids in near-Earth space.

Within the framework of a program initiated by NASA in 2005, scientists are currently discovering, on average, around 30 new celestial objects within the Solar System every week. In contrast, in 1998, this amount was found only over the course of an entire year.

There may be habitable planets orbiting the nearest stars.

In August 2016, scientists discovered the exo-planet Proxima b, which orbits within the habitable zone around the star Proxima Centauri. Its surface temperature is such that there may well be liquid water there. If scientists can work out whether the planet possesses a magnetic field and an atmosphere, then it’s entirely possible that Proxima b supports life.

Scientists have found evidence that confirms the existence of black holes.

In February 2016, scientists discovered evidence of the existence of gravitational waves. This discovery, in turn, confirms the existence of black holes. Moreover, if scientists can study the waves that formed as a result of the Big Bang, they’ll be able to finally determine the mechanism that led to the creation of the Universe.

COROT-7b — the volcanic planet where rocks fall like rain.

This exo-planet is very close to its star, so the surface temperature is hot enough to vaporize rocks and pebbles condensed out of the air. It also rains rocks into lakes of molten lava.

To realize how small we are take a look at this picture.

The diameter of VY Canis Majoris, one of the largest stars, is approximately 2000 times that of our Sun’s and 155,000 times that of Earth’s.

What was Earth like 4.5 billion years ago?

If we traveled back in time and saw Earth 4.5 billion years ago we’d notice that its color was not blue but reddish-yellow. Around the planet there was debris that had formed Moon after the collision between Earth and Theia. The then Moon shone like the present day Sun and influenced the gravity of our planet 25 times more greatly.

The influence of the Moon resulted in huge lava waves on Earth. Besides, the planet could rotate once on its axis in 6 hours only.
