Big Bang: Time

[Sadovnik Socratus]

   Big Bang: Time

=.

Big Bang is seriously taken by cosmologists and according

to current cosmological scenarios:

a) In the past, maybe 50 or 100 billion years ago, the Universe

as whole reached its maximum radius.

b) It took another 50 or 100  billion years when the Universe

as whole came to singular point.

c)  Today we see the Universe at age 13,7 billion years.

Question.

Why do cosmologists say: “Before Big Bang there was no time”?
