No, the closest we have gotten is 99.9% using special coatings like the ones on eyeglasses. These will only reflect specific wavelengths in a lab setting. In comparison the aluminum mirror in your bathroom will have between 85 -90% efficiency. (Even if you kept it completely clean) A high quality silver mirror can achieve 95% efficiency. The rest will either be absorbed by the metal or refracted by imperfections in the glass or metal.
It is theoretically not possible to create a 100 percent effective mirror due to the fact that visible light is a relatively wide spectrum that will behave differently at either end. (Blue light will be reflected slightly differently than red light etc.)
Mirrors exist as a result of the reflection of light. When light hits a smooth surface, such as glass, it bounces off in a way that produces a clear reflection of what is in front of it. This phenomenon is what allows mirrors to reflect images back to us.
You cannot. X-ray vision is a topic of science fiction and is not actually possible.
Mediums are made of molecules. Actually, we're all made of molecules whether we are mediums or not. We require molecules to breath, to drink, to eat, and to exist. Psychic ability has no bearing on one's need for molecules.
Reality refers to the state of things as they actually exist, rather than as they may be perceived or thought to be. It encompasses the physical world, events, and experiences that are tangible and verifiable.
Yes, wormholes are theoretical passages through spacetime that could potentially exist according to some scientific theories, such as general relativity. If wormholes were to exist, they could have significant implications for our understanding of the universe by potentially allowing for faster-than-light travel and providing shortcuts through space and time. However, their existence has not been proven, and much more research and evidence are needed to confirm their existence and understand their implications fully.
In a PERFECT System with Perfect Mirrors reflecting 100% of the Energy that strikes it....two parallel mirrors will reflect light striking it at 90 degrees to their surfaces an INFINITE number of times. Of course that System does not exist. Mirrors are NOT 100% Reflective. It is impossible to make two flat objects Perfectly Parallel, and Introducing a Perfectly Perpendicular Light Beam into the System is NOT Possible either.
The Mirror of Erised and the two-way mirrors are not real things.
They do not exist.

Actually quarks can exist freely.
Yes.
No
There was about 76 percent but now there is only about 20 percent.
Herobrine doesn't exist,he is actually a Creepy Pasta
If you're asking about positions, then yes. As a violinist of over 10 years, I use various positions in every piece I play.
No
Yes it does
