How would life be different if albert Einstein was not born?

Answer 1

Perhaps not that different; although Einstein is credited with four extraordinary insights; explaining Brownian motion - which proved the existence of atoms as real things - extending the Doppler affect to light, which allowed the calculation of the distance and speed of receding stars and galaxies, special relativity and general relativity, other scientists were working in the same areas - and in some way, Einstein won "races" to publish first.
