Evidence for Big Bang:

Evidence for what, exactly? Our entire observable universe was once as hot as the core of the Sun, doubling its size in a under a second.

•  Observed galaxy recession (Hubble’s law)

•  Existence of CMB

•  Correct predictions of big bang nucleosynthesis

•  Darkness of night sky! (Olber)

•  Distant objects look younger

•  Not evidence for a singularity

Plenty enough bang for most people to call “big”…

EVIDENCE: The Universe is

expanding! v=Hr

Alexander Friedmann 1888-1925

(Russian; 1922 paper)

George Lemaître 1894-1936 (Belgian; indep. 1927 paper)

Arthur Geoffrey Walker 1909-?

(British; 1935 paper with H P Robertson showed that FLRW

metric is only homogeneous & isotropic metric)

Edwin Hubble 1889- (American; 1930 paper)

Mt. Wilson Observatory 1931

Hubble 1929:

H≈550 km/s/Mpc

Riess et al 1996:

H≈70 km/s/Mpc

How measure distance & redshift?
