18. Around 75% of the universe is missing in the form of dark matter and dark energy, according to scientists which can’t be measured.
19. The glue that holds the universe together is dark matter, which can’t be measured, but scientists believe that there is a chance of measuring it.
20. From outer space, cosmic rays flow throughout our solar system, which are highly energetic particles. But no one is aware of their origin.
21. Our solar system, with the sun, the planets, moons and the billions of asteroids and comets fill less than a trillionth of our universe.
22. The edge of our solar system is not Pluto, it is theorized Oort cloud.
