The Universe

The universe according to…

I’m addicted to watching TEDTalks videos on YouTube.  According to the website: “TEDTalks shares the best ideas from the TED Conference with the world, for free: trusted voices and convention-breaking mavericks, icons and geniuses, all giving the talk of their lives in 18 minutes.”  My favorite TEDTalks video so far is Stephen Hawking: Asking big questions about the universe.  As of today, it’s been viewed almost 2.8 million times.

Stephen Hawking was born in Oxford, England in 1942.  He was diagnosed with ALS (Amyotrophic Lateral Sclerosis) at the young age of 21.  Hawking is a theoretical physicist, author, Honorary Fellow of the Royal Society of Arts, member of the Pontifical Academy of Sciences, the Presidential Medal of Freedom awardee, and University of Cambridge teacher.  He has said that his disability allows the time to investigate the universe.

Hawking: “My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.”  In the TEDTalks video Hawking discusses these questions:

  1. Where did we come from?
  2. How did the universe come into being?
  3. Are we alone in the universe?
  4. Is there alien life out there?
  5. What is the future of the human race?

Hawking investigates the Big Bang and what existed before the universe.  He discusses how the universe can create itself out of “nothing.”  He believes it’s possible for life on other suitable planets.  Also, the earth was created 4.7 Billion years ago and too hot for life at that time.  As a result, life appeared 1 billion years after creation.  The life span of planet earth is about 10 billion years.

In the video, Hawking believes that aliens haven’t visited us yet.  He states:  “If we’re the only intelligent beings in the universe we should do everything possible to survive and continue.”  However, with population increases and the over use of energy consumption, it will be difficult for the human race to continue for the next 100 to one million years.  As a result, humans will have to spread out into space and colonize other planets.

When asked about other life in the Milky Way galaxy, he believes mostly likely not because of the lack of radio wave evidence.  Also, other civilizations might have destroyed themselves.  Hopefully, humans on planet earth will respect planet Earth and work together.

If we’re the only intelligent life in the Milky Way galaxy, then let’s start acting like it.  That way our galaxy doesn’t have to be the black hole out of one hundred billion galaxies…
