This video provides an entertaining look at some of the ideas people have about the zero-gravity environment on board an orbiting spacecraft, and shows why the astronauts actually appear weightless. But let’s discuss it, too: When asked why objects and astronauts in spacecraft appear weightless...
According to the text, why do we feel weightless in space? E. The force of gravity is weaker in space. F. There is no gravity in space. G. Objects in space have no mass. . Distance has no effect on gravity in space.( )35. Which of the following statements is NOT true according...
Voices are almost the only things that are not changed by being weightless,which means that everything has almost no weight in space. Some astronauts feel sick for the first few days in space.Some feel as if they have a cold all the time.That's because without gravity(...

Astronauts first feel the influence of weightlessness(失重)when the rocket engines are turned off.Straight away, they begin to float (漂浮), held down only by seat belts. Weightlessness allows astronauts to appear. superhuman strength. They can lift objects that would be far...
Just like thespace race in the 1960s drove US technology, Starshot could deliver more than just snapshots from Alpha Centauri. Starshot's researchers are particularly struck by the idea of using the laser to propel heavier objects shorter distances. ...
All the time there was this great intensification of light and energy and outline of objects in the room, and this wonderful feeling that I had somehow become a part of everything, and attached to something. At the same time I realize that strength and understanding were being given to me...
