The Biggest and Smallest
From the
enormous universe in which we exist to tiny
atoms that make up the building blocks of
everything around us, size matters when it comes
to understanding the cosmos.
Starting with our solar system, we’ll explore
the true meaning of word “big.” Odds are you saw
a model of the solar system made in grade
school.
With incredibly realistic CGI, we’ll reveal how
that model, if built to scale, wouldn’t fit
inside a football field, much less a classroom.
The Most Explosive
Scientists
believe that our universe started with a
colossal explosion called the Big Bang.
That powerful blast created all the matter in
the universe and laid the groundwork for every
explosion since.
From exploding stars to asteroid impacts, Known
Universe: The Most Explosive deconstructs some
of the biggest explosions in the universe with
unforgettable CGI and slow-motion footage.
Even a devastating earthquake would be tiny
compared to what would happen if an asteroid six
miles across slammed into Las Vegas.
In spectacularly realistic CGI, experience the
impact and its blistering shockwave. Discover
how scientists have devised strategies to
harness the sun’s explosive power to divert
dangerous meteorites from slamming into the
Earth.
The Fastest
In the vast
expanse of space, nothing matters more than
speed. Whether were venturing out to the
farthest reaches of our solar system or
exploring the mysteries of time travel and
wormholes,
speed is
the key.
