This is invented by G.GAMOV om 1956 based on Huble¡¯s expansion
theory that super-atoms including all the materials of the universe
has been exploded and expanded to date.
1. Original atom : The initial small mass is called ¡°original atom¡±.
It is densely compacted with neutrons only and its temperature is
regarded as 100 billion K.
1. Eruption : After the eruption of the original atom, some atoms
are created in 30 minutes and they are flocked to become a star
which is still expanding. The great explosion is called ¡°Big Bang¡±
and it is based on the theory of the great explosion.
2. The age of the universe : According to Huble¡¯s Law V = H ¡¿ r,
if the galaxy far from r distance is moving with V velocity, r/V
implies the time of running r distance with V velocity and then
our galaxy and this galaxy are regarded as being together at the
same amount of time in the past. In other words, according to the
theory of great explosion, r/V = 1/H = t0 is numbered as the age
of the universe. If H = 55km/s/Mpc, t0 = 1/H = 1 / 55km/s/Mpc ¡Ö
2x10; 102 year Thus, the age of the universe is estimated
as about 20 billion year.
