It is difficult to get magnesium in pure form at home. Mostly it will be available in alloy form in some metallic structure like car or laptops. The magnesium in most of the supplements and antacids are present in salt form. Some type of firecrackers contain magnesium. You can find out the composition if you have any firecracker.
Primarily, there are two reasons why we sometimes see the moon during the day. First of all, the moon is bright and close enough to be seen against the blue hue of the sky. Secondly, the duration for which it is above the horizon of Earth coincides with the sun, making it possible to be seen during the daytime.
The most common color for the sky on Earth is a white (or rather grey) sky. Clouds cover around 70% of the Earth, and nature by which they are scattering shortwave radiation makes them appear white or grey.
I think that. No, a black hole is not really a hole at all. A black hole is an object just like any other, except that it is extremely dense. This gives it such a high gravitational field that nothing, not even light, can escape. Because no light escapes a black hole, it is invisible – or ‘black’ – although they can be detected by their effect on the material around them. The term ‘hole’ was used because whatever falls ‘into’ a black hole is trapped forever.
Black holes are one of the weirdest phenomena in the World. A black hole is a space-time area where gravity is so strong that nothing can escape. Light is sucked into it, thus the term 'black hole.' Since no light can get out of black holes, they're invisible. A space telescope with special equipment is needed to locate a black hole. It's a massive amount of stuff crammed into a minimal place.
