Traveling Back in Time? | StarTalk

you’ve had a time machine I think I’d go
back to when a mars-sized protoplanet
sideswiped earth in the early solar
system sideswiping our crust casting
billions of tons of rock into orbit
around the earth
which then coalesced to form our moon I
want I want to be around when that
happened
and by the way back then the moon would
have formed much much closer to the
earth so the moon would’ve been huge in
the sky raising really high tides just
that whole episode I want to bear
witness to it who doesn’t love a good
collision especially if a collision and
an explosion creates something
explosions and collisions that are
portrayed in media today they something
has always destroyed but this is one
thing that actually created something
beautiful our Moon now if I were to go
back in time to when humans still
existed I would go back i chilled with
Isaac Newton yeah just to tell him how
significant his discoveries were in
establishing what we now take for
granted as modern civilization the
Industrial Revolution he was the first
person to really put on the page the
fact that the universe is knowable oh my
gosh
the universe is knowable that means we
can figure it out
manipulate it adjust it do things with
the universe that are in the service of
our curiosities we used Isaac Newton’s
laws to get to the moon his laws of
motion and his laws of gravity I would
tell him this I think he he’d want to
know that
