2. In the absence of gravity, spiders weave a spherical web. This was confirmed by a series of experiments aboard the International Space Station.

3. Astrophysicists claim that at the center of our Galaxy is a supermassive black hole with a mass of about 3,000,000 times the mass of the Sun. It has such powerful gravity that the arms of the Milky Way revolve around it like the planets of the solar system revolve around the sun.

4. A number of bacteria in the absence of gravity becomes much more dangerous.
