Through the initial three minutes from the universe, the light elements had been born in the course of a method called Major Bang nucleosynthesis. Temperatures cooled from a hundred nonillion (1032) Kelvin to one billion (109) Kelvin, and protons and neutrons collided to produce deuterium, an isotope of hydrogen. A lot of the deuterium mixed to create helium, and trace quantities of lithium have been also generated.
Even now the universe is growing. To astronomers' shock, the pace of expansion is accelerating. Estimates on the enlargement rate vary, but data through the James Webb Space Telescope adds to the rising physique of evidence that it's substantially more quickly than it ought to be.
The smallest World inside our solar system and nearest for the Solar, Mercury is barely marginally larger sized than Earth's Moon.
