To that end, they have been studying how other species deal with low gravity, specifically focusing on mice. The results are both interesting and humorous. The scientists first sent some mice in a specially designed cage to the International Space Station. The cage allowed them to study the ...
Effectively managing human waste is critical for the health and safety of astronauts in space.Our terrestrial toilets use gravity to flush everything away, but doing your business in the weightlessness of outer space gets tricky. So, how exactly does one go number one, or number two, in space...
When theres an earthquake, we need to run to the open space, and remember, when you get to the open space, put your hands on your head. When you are in school, you have to follow your teachers instructions. At home at school when you cant run out to the toilet, or squat under th...
Traveling higher would make a bigger dent in gravity’s influence, but you won’t escape it. Gravity is generated by variations in the curvature of spacetime – the three dimensions of space plus time – which bend...
(absent) of gravity in space,astronauts usually sleep in a sleeping bag and have to attach themselves (3) to avoid (avoid) floating around.Their main task inside the space station is to conduct scientific research and with the space station (4) ...
How do they exercise? There are good exercise machines in the space station. They make it easy for astronauts to keep healthy.There is no gravity, so astronauts can't take showers like we do on Earth. Is there a bathroom in the space station? How do they keep themselves clean? Don't...
to up to three times normal gravity (some roller coaster rides can achieve this level of acceleration). Your chest feels compressed and you may have some difficulty breathing. Yet, in about 8 and a half minutes, you are in outer space, experiencing an entirely different sensation:weightlessness...
Once aloft, gravity (the weight of the hang glider and pilot) pulls the glider back toward Earth and propels the glider forward, continually causing air to flow over the wing. In addition to the horizontal movement of air, hang gliders can get lift from rising currents of air, such as ...

That's why we need to look at Einstein's later theory, theGeneral Theory of Relativity, which describes how gravity affects the shape of space and flow of time. Imagine a stretched-out sheet. If you place a bowling ball in the middle of the sheet, the sheet will warp as the weight ...
