This estimate came from measuring the composition of make any difference and energy density inside the universe. This allowed researchers to compute how briskly the universe expanded in past times.

With that knowledge, they could transform the clock back and extrapolate if the Major Bang happened. The time among then and now will be the age on the universe.

Water covers 70% of Earth's surface. Earth's atmosphere is produced mainly of nitrogen and has lots of oxygen for us to breathe. The environment also safeguards us from incoming meteoroids, a lot of which split up right before they're able to strike the area.

Given that the universe expands, the energy density of electromagnetic radiation decreases a lot more quickly than does that of subject as the energy of each photon decreases as it can be cosmologically redshifted.
