Three ideas important in framing the universal context: Implies and enormous number of worlds on which life might exist: the universe is vast and old.

Every experiment and observation made to date has given additional support to. Ne(cid:449)to(cid:374)"s (cid:272)o(cid:374)(cid:272)lusio(cid:374) that the la(cid:449)s of (cid:374)ature are the sa(cid:373)e e(cid:448)ery(cid:449)here.
