Avoiding the Crash Wall

President Obama won the Nobel Peace Prize “for his extraordinary efforts to strengthen international diplomacy and cooperation between peoples.”
Let us wish him well for all our sakes.

I intend to close Guantanamo, and I will follow through on that. I have said repeatedly that America doesn’t torture. And I’m gonna make sure that we don’t torture. Those are part and parcel of an effort to regain America’s moral stature in the world.
Quotation from President Barack Obama

If you’re walking down the right path and you’re willing to keep walking, eventually you’ll make progress.

Deja Vu is the Collisional Cascading of the Past with the Present

Deja Vu is the Collisional Cascading of the Past with the Present

The risk of collisional cascading is called Kessler’s Syndrome. When U.S. and Russian satellites collided in space this week, more than 600 bits of debris joined 18,000 other objects orbiting our planet. These artifacts, including rockets, satellites, bolts, screws, pieces of titanium and paint flecks, travel faster a bullet. They pose a danger to other space vehicles, including the International Space Station. Kessler’s Syndrome describes a situation where each collision causes more debris which causes more collisions, until it is unsafe for anything to orbit the earth.

Space isn’t remote at all. It’s only an hour’s drive away if your car could go straight upwards.
Quotation from Sir Fred Hoyle
