Science

In the Beginning• Force Unification Theorem– Electromagnetism• Photons

–Weak Force• W-,W+, Z0,-bosons

– Strong- (Colour-) Force• Gluons

– Gravity• Gravitons

The Bang• Singularity now! (why? Dunno..)– Temperature: 1032c°

• Gravity seperates at Planck Second. (10-42)• Strong Force seperates at 10-35s

– Triggers expansion• Cooling down (1027c°)– Quark

• 1015c°and 10-12second, Em and W seperates.– Leptons

• 10-6 Atoms.

Evidence for Big Bang

• Metric Expansion of Space• Background Radiation• Primordial Nucleosynthesis

Metric Expansion of Space• Bread Dough Effect– Quadratic Equation

Background Radiation• High frequency radiation– Hawking Radiation

• Massiver than Supermassive Black Holes

Primordial Nucleosynthesis• Isotopes of Hydrogen and Helium– Protium, Deuterium, Tritum, H-4, and so

forth.
