... by pulling yourself along the insides of the spaceship? Is it like flying like a bird or swimming like a fish, or both? It is not hard to adapt to floating, over a period of a day or so, since your body really adapts to weightlessness. It is very easy to move around. In fact, with three dimensions instead of two in which ... moving in the correct direction, and then you float to where you want to go. It's really like flying, not like swimming. ---- Answer provided by Byron Lichtenberg, Ph.D. Image ...

... storm of swirling clouds that has lasted for more than 300 years. This massive storm is about three times the diameter of the Earth. Galileo launched a probe that recorded winds ... miles per hour within the swirling storm. Currently, the Great Red Spot is only about half as large as it was 100 years ago. Scientists do not know how long the storm ...

... distance is 93 million miles. It is so far that even light takes eight minutes to cover the distance. In fact, when we see the Sun, we are seeing it eight minutes ago. Imagine It ...
