The Fermi Gamma-ray Space Telescope, formerly GLAST, will open this high-energy world to exploration and help us to answer these questions. With Fermi, astronomers will at long last have a superior tool to study how black holes, notorious for pulling matter in, can accelerate jets of gas outward at fantastic speeds. Physicists will be able to study subatomic particles at energies far greater than those seen in ground-based particle accelerators. And cosmologists will gain valuable information about the birth and early evolution of the Universe.

before space there was no space - so the big bang occurred no where but everywhere how can there be a time before the bang when there was no such thing as time before the bang? before time there was not any time- - so, no time before time!

Astronomers don't want you to know that there are stars older than the universe. The reason why contradicts their orthodoxy.

Time is flying by on this busy, crowded planet as life changes and evolves from second to second. And yet the arc of human lifespan is getting longer: 65 years is the global average way up from just 20 in the Stone Age. Modern science, however, provides a humbling perspective. Our lives indeed the life span of the human species are just blips compared to the age of the universe, at 13.7 billion years and counting. It now seems that our entire universe is living on borrowed time. How long it can survive in any form depends on whether Stephen Hawking's theory checks out.

Stephen Hawking - We must colonize space in order to survive
Note: I edited this video, here is the full 10mins. Stephen Hawking: Asking big questions about the universe http://www.youtube.com/watch?v=xjBIsp8mS-c http://www.ted.com In keeping with the theme of TED2008, professor Stephen Hawking asks some Big Questions about our universe -- How did the universe begin? How did life begin? Are we alone? -- and discusses how we might go about answering them. PLEASE SUBSCRIBE TO: http://www.youtube.com/user/TEDtalksDirector "Since, in the long run, every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring--not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive... If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds." Carl Sagan, Pale Blue Dot, 1994 "We need the stars... We need purpose! We need the image the Destiny [to take root among the stars] gives us of ourselves as a purposeful, growing species. We need to become the adult species that the Destiny can help us become! If we're to be anything other than smooth dinosaurs who evolve, specialize and die, we need the stars.... When we have no difficult, long-term purpose to strive toward, we fight each other. We destroy ourselves. We have these chaotic, apocalyptic periods of murderous craziness." Octavia Butler, Parable of the Talents, 1998 "I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars." Stephen Hawking, interview with Daily Telegraph, 2001 "The dinosaurs became extinct because they didn't have a space program. And if we become extinct because we don't have a space program, it'll serve us right!" Larry Niven, quoted by Arthur Clarke in interview at space.com, 2001 "In time, [a Martian] colony would grow to the point of being self- sustaining. When this stage was reached, humanity would have a precious insurance policy against catastrophe at home. During the next millennium there is a significant chance that civilization on Earth will be destroyed by an asteroid, a killer plague or a global war. A Martian colony could keep the flame of civilization and culture alive until Earth could be reverse- colonized from Mars." Paul Davies, The New York Times, 2004 "We must turn our guns away from each other and outwards, to defend the Earth, creating a global and in space network of sensors and telescopes to find asteroids that could destroy our planet and create the systems to stop them. It makes no sense to dream great dreams while waiting to be hit by a train." Buzz Aldrin and Rick Tumlinson, Ad Astra Online, 2006
