Did Galileo Get It Right?

In the folklore of physics, no story is better known than the tale of Galileo dropping balls from the Leaning Tower of Pisa and proving gravity accelerates all objects equally, regardless of their masses or composition. This is called the “equivalence principle” and it is a cornerstone of modern physics. But was Galileo correct? Read what scientists are doing to find out.

Weightless in Space

If you watch anything about space travel on TV, they often talk about things being “weightless” in space. In fact, they still have weight. For example, equipment on the International Space Station still weighs about 90% of their weight on the surface of the Earth. So how can astronauts and other things float around inside the ISS or any other spacecraft? Try this free-falling water experiment to find out.

Humans in Space

Should humans go into space? Do you believe in extra-terrestrial life?
It takes 6 months to get to Mars. What food would you take? Why? What else would you need to have with you? Who would you pick to have on your crew? What would you miss most about home? What kind of people should be the first to inhabit Mars?
