Part 4 Reaching for the Stars Space Exploration - BBC Explorations

Explorations this time tells the story of our place in space.
At the Keck Observatory in Hawaii, scientists are engaged in one of the most important quests of modern astronomy. They're scanning the universe for new planets. Planets that might support life now or in the future. Planets that might be like earth. Our desire to reach out into space is a compulsion. The more we soar, the greater that compulsion. In the 1970s, after decades of careful planning, 4 probes, Pioneer 10, Pioneer 11, Voyager One, and Voyager 2 were sent on missions to the outer limits of our solar system. Their journeys would last almost 30 years, and cover more than 8 billion miles. These probes brought mankind astonishing images of the planets in our solar system. Mankinds first giant leap was made with hot air in balloons. Tied to balloons, man could leave the ground and travel higher than ever before. In 1960, a balloon carrying US airforce captain Joe Kittinger ascended to the edge of space, some 100,000 feet off the ground. Then he jumped out. In 4 minutes, Kittinger reached the speed of sound

@Goodcapcay Gravity is just a theory

[balltip]

@1kingconan

Oh I know. I am referring to comparisons made if you look at the strong and weak nuclear force, the electromagnetic force, and gravity. In that case, gravity is the, by far, weakest force. :)

[1kingconan]

@balltip depends how you measure gravity. if you put gravity in one small spot ie black hole then gravity can be very powerful :D

[Daniel18uk]

@Goodcapcay And it is also infinite, and I would too agree with narrator ^^

[balltip]

"...overcome the greatest force in our universe; gravity."

This is blatantly WRONG. Gravity is actually the weakest force of the four known forces.

Google "four forces of nature" and see for yourself. (This also goes out to the narrator...)
