you have a question you have a question
you got a question on the universe how
are you sir and you are and my name is s
s pleasure you have a question on the
universe yes I got a question for you I
want to know how you get storyed what St
your interest as a kid when I was a kid
I was 9 years old it was my first visit
to the local Planetarium and I grew up
in New York city so the local
planetarium is the Hayden Planetarium
and I looked up at the night sky and the
light dimmed and the stars came out I
thought it was a hoax because there were
so many stars and I'd seen the night sky
from the Bronx okay it only had like a
dozen stars in it so I thought it was a
hoax I said this is an entertaining hoax
but a hoax nonetheless and I would only
later learned that that represented the
real sky but I was hooked ever since
ever since I was 9 9 years old yeah
let's good to go I they contemplating
going and and doing some maintenance on
the Hub scope yes my question to you is
what that Hubble you know done in terms
of confirming what youve known or
clarify what you've known of the heavens
with the one of the great discoveries of
the Hubble telescope there's a whole
list of discoveries the Hubble telescope
part of what made it so fertile as a
scientific instrument is that we were
able to go back to it and service it to
replace the bad parts to upgrade ones
where we've got better technology better
detectors and so the the telescope just
kept getting better and better and
better so so one of the things it
confirmed was that there are black holes
lurking in the centers of all galaxies
every Galaxy where we have good enough
data to know one way or another there's
a black hole sitting in the center of
that galaxy ours included not only that
we confirmed what the expansion rate of
the universe is so we know how big the
how big the universe is and how fast
it's moving and how old it is it's it'd
be like growing up in life and not
knowing when you were born that that'd
be tragic if you didn't know that so
it's answering fundamental questions
we've had not only about cosmology but
also it's it's enabled us to probe
regions of the Galaxy where stars are
being born and so not only the birth
lives and deaths of stars but the birth
of the universe itself no and then I'm
going don't want to thank you very much
for you know providing this venue for
young kids with you know wondering and
and curious minds that to open you know
kids are born with curious minds it's
the adults I'm trying to get back into
their as well
too too many adults not dreaming about
the universe the way all the kids are we
got the kids I'm worried about the
adults all right all right great thanks
a lot thank you
