the strongest evidence in support of the big bang theory is the detection of the cosmic background radiation, remnant of the big fireball at time zero. This radiation has a thermal energy of about 3 degrees kelvin (ancient old photons from the big bang itself but still travelling at lightspeed with much lesser energies). Thermal equilibrium between the energy from matter and energy from space expansion agrees perfectly with the recent findings of the COBE satellite to fit a blackbody radiation curve.
