The big bang

The begining of the Big Bang Theory

The year it was first theoriesed by Georges LemaÎtre

A world egg or cosmic egg is a mythological motif found in the creation myths of many cultures and civilizations. Typically, the world egg is a beginning of some sort, and the universe or some primordial being comes into existence by "hatching" from the egg, sometimes lain on the primordial waters of the Earth.

So the 1929 discovery by Edwin Hubble that the Universe is in fact expanding at enormous speed was revolutionary. Hubble noted that galaxies outside our own Milky Way were all moving away from us, each at a speed proportional to its distance from us.

In 1996, observations of distant supernovae required a dramatic change in the picture. It had always been suggested that the matter of the Universe would slow its rate of expansion. Mass creates gravity, gravity creates pull, pulling must slow the expansion. But supernovae observations showed that the expansion of the Universe, rather than slowing, is accelerating. Something, not like matter and not like ordinary energy, is pushing the galaxies apart. This has been dubbed dark energy, but to give it a name is not to understand it. Whether dark energy is a type of dynamical fluid, heretofore unknown to physics, or whether it is a property of the vacuum of empty space, or whether it is some modification to general relativity is not yet known.

Cool FactThe Cosmic Egg has 7 different mytholical means. Greek, Egyptain, Chinesse, Phoenician, Vedic, Finnish and modern.

Cool FactDark energy takes up 72 percent of the mass and energy of the universe. Without it, gravity would cause the universe to collapse in on itself

Georges Lemaritre was the first person to theories "The Big Bang". He first started his study on The expansion of earth after Albert Einstein publised a paper on the "laws of Gravition." Georges was a Christain minister

1927

The year the Cosmic egg first theorised. Georges was the man to do this.

1931

In this year Edwin hubble attempted the same experiment as Georges did two years earlier and got the same conclussion

1929

1996

The years following Hubbles and C.O.B.E theories came along Dark Energy

The Big Bang Theory The Big bang theory is a theory about the begining of earth. Earth itself has no know beginings but we do have theories on how earth is expanding.
