Radioactive age dating equation

As long as they are emitting heat and light into space, stars are able to support themselves against their own inward gravity with the outward pressure generated by heat from nuclear reactions in their deep interiors.

The planet was exhausted from World War I, eager for some sign of humankind's nobility, and suddenly here was a modest scientific genius, seemingly interested only in pure intellectual pursuits. Einstein's earlier theory of time and space, special relativity, proposed that distance and time are not absolute.

If gravity is equivalent to acceleration, and if motion affects measurements of time and space (as shown in special relativity), then it follows that gravity does so as well.

In particular, the gravity of any mass, such as our sun, has the effect of warping the space and time around it.

A black hole would thus appear black from the outside.

(However, gas around a black hole can be very bright.) It is believed that black holes form from the collapse of stars.

The first black hole believed to be discovered in the physical world, as opposed to the mathematical world of pencil and paper, was Cygnus X-1, about 7,000 light-years from Earth.

(A light-year, the distance light travels in a year, is about six trillion miles.) Cygnus X-1 was found in 1970.General relativity may be the biggest leap of the scientific imagination in history.Unlike many previous scientific breakthroughs, such as the principle of natural selection, or the discovery of the physical existence of atoms, general relativity had little foundation upon the theories or experiments of the time.One of the most stunning successes of the Big Bang theory is the prediction that the universe is approximately 10 billion years old, a result obtained from the rate at which distant galaxies are flying away from each other.This prediction accords with the age of the universe as obtained from very local methods, such as the dating of radioactive rocks on Earth.According to the Big Bang theory, the universe may keep expanding forever, if its inward gravity is not sufficiently strong to counterbalance the outward motion of galaxies, or it may reach a maximum point of expansion and then start collapsing, growing denser and denser, gradually disrupting galaxies, stars, planets, people, and eventually even individual atoms.
