Exercises to Avoid. While most exercises are safe during early pregnancy, you should avoid certain activities all together. Avoid contact sports such as rugby, tackle football or wrestling during pregnancy. Additionally, stay away from activities with a high fall risk such as downhill skiing and skating.
Fred Hoyle (and others) proposed a Steady State Theory (indeed, it was good ol' Fred who is credited with creating the term 'Big Bang' - ironically, he meant it disparagingly); it pretty much disappeared once serious study of the cosmic (background) (microwave) (radiation) - CMBR, or CMB, or ... - got under way.
An alternative model which once enjoyed equal status with the big bang is the steady state theory, first proposed in 1948 by Hermann Bondi, Thomas Gold, and Fred Hoyle. This model, too, assumes that the universe is expanding, but proposes that it has no beginning or end in space and time.
