Can a fire have a shadow ?
Yes, you can form the shadow of a fire, but perhaps not for the reason that you are thinking. A shadow is formed any time part of a light beam is blocked or redirected. The shadow region is the region in the light beam where there is less light than in the rest of the beam.

See lessIs a black hole a 2D or 3D object ?
A black hole is actually a four-dimensional object. A black hole extends across all four physical dimensions of the universe. The four dimensions that form the background framework of the universe consist of three spatial dimensions and one time dimension. These four dimensions are inseparably conneRead more
A black hole is actually a four-dimensional object. A black hole extends across all four physical dimensions of the universe. The four dimensions that form the background framework of the universe consist of three spatial dimensions and one time dimension. These four dimensions are inseparably connected into one unified framework called spacetime. While it may sound exotic to say that a black hole is a four-dimensional object, the mundane truth is that all physical objects are four-dimensional objects .
See lessDo kirlian photographs show the soul of an organism ?
No, Kirlian photographs do not show the soul of an organism. Kirlian photographs show the light that is released by the electrified air surrounding an object when the object is intentionally filled with electricity.

Koalas are only found in Eastern and Southern Australia.
See lessWhy dont metals burn ?
Because most atoms in a solid chunk of metal don't have access to oxygen atoms, because metals have a high ignition temperature, and because metals are good thermal conductors, they don't burn very well in everyday situations .

See lessAre we alone in the universe ?
Astronomers have been searching the universe for signs of other life as well as habitable planets. Astronomers have created radio telescopes which pick up messages from other planets, as well as scan atmospheres of other planets to detect habitable conditions which might be home to other lifeforms.Read more
Astronomers have been searching the universe for signs of other life as well as habitable planets. Astronomers have created radio telescopes which pick up messages from other planets, as well as scan atmospheres of other planets to detect habitable conditions which might be home to other lifeforms. The scans have revealed a whopping 60 billion habitable planets in the Milky Way.
