National Geographic Channel brings you a new series that goes to the farthest reaches of space.
國家地理頻道為您帶來一系列深入外太空的新節目。
If we could
venture out to
the very edge of our universe, what would we see? Where does the universe end? And how will the universe end? With four new
specials, National Geographic Channel's
Space Week offers an
epic voyage across the
cosmos. It
illustrates the birth of stars, life on other planets, terrifying
black holes, and the
ultimate fate of the universe. Using the most
advanced digital image programs, the series
displays the environment found outside of our planet
in, amazing
detail.
The program "Death of the Universe" looks carefully at three theories about how the universe will end. The theories put the
demise some 50 billion years from now, so you don't have to worry too much
at the moment. Still, the destruction sounds absolutely
nightmarish.
Previously, scientists thought that the universe would end in a "Big
Crunch," where the universe
retracts back to its original size.
Picture a balloon losing its air. However, now
astronomers have different ideas that are based on two things that exist in space:
dark energy and
dark matter. One theory says that these
opposing forces will
rip the universe
apart, atom by atom. Another theory says that the universe will
keep on expanding until stars gradually
fade and the universe is cold and
lifeless. Luckily, none of us will be around to
find out which theory is correct.
A more peaceful journey through space is
provided in "Journey to the Edge of the Universe." The program uses a single,
unbroken shot to show what we would find if we were able to travel to the farthest
reaches of the universe. Voyage with National Geographic past Venus and Mars to a star system 90
trillion kilometers away, passing through other
galaxies that
are not too
different from our own.
The mysteries of space have always
intrigued people. Don't miss this chance to find out more!
