I'm dr. Stewart Clark I'm an astronomer
and I'm the author of the unknown
universe it's so clearly obvious that
the world isn't flat we see when ships
leave the harbor you can see as they
gradually disappear below the horizon
you can see if you go up onto a tall
tower or a hill and you see more over
the horizon all our physics is
constructed now the physics of orbits
actually things going around the earth
is all constructed with this with three
dimensional spherical world and the
pictures from from space show our world
as a globe and yet somehow oh yeah there
are some some people that still seem to
believe that the earth is flat so as
human beings we love stories because
stories make sense of our lives of our
world
they endow it with meaning and they can
be understandable science is a way of
constructing what we hope is is a true
story
something that is is demonstrably true
through experiment but as we see
throughout the ages the prevailing
scientific theories of the day can be
overturned as we move to more precise
understanding of the universe around us
and generally speaking those become more
complicated so there is a tendency for
people to reject that reality the
science of the day and just fall back on
on uncomfortable myths things that make
them feel at home things that make them
in a much happier that they know what's
going on maybe this is obsession with
Flat Earth the Flat Earth is one of
those or maybe they're just people just
contrarian I don't know it's one of
those things that I find it so difficult
to get my head around I mean I really do
my own pet theory is that they're just
doing it for comic effect just to see
how far they can go she ate imagine for
a moment that yet the earth that the
earth was flat
well how much thickness does it then
have these are the kind of questions
you'd have to ask you know KK you've got
an age well would things fall off the
edge well how do you generate gravity to
make the things fall what is it there's
actually causing the gravity to make
things fall off the off the end a flat
surface is fairly unstable to the other
forces it would it would be flexible and
moved around I it's hard to even begin
actually to talk about what what a flat
earth would be like because it's just
it's just so impossible
