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.)

Why do mirrors exist?
Because if they didn't we would get bored with the videos of cats looking at themselves =D
What would the world be like if Albert Einstein didnt exist?
If Albert Einstein didn't exist, then all of the stuff he discovered would be discovered later on and Albert Einstein's theory of relativity wouldn't exist until someone else states it later on. However, according to the QI Book of General Ignorance, Galileo Gallilei was the first to state the theory of relativity, so it would actually exist in today's world.
What is potential resources?
Potential resources are those that exist in a region and may be used in the future. For example, petroleum may exist in many parts of India, having sedimentary rocks but until the time it is actually drilled out and put into use, it remains a potential resource.
Where was Bose Einstein condensate found?
Bose Einstein condensate was not actually found but predicted by albert Einstein. It would be impossible for Bose/Eistein condensate to exist, but Einstein got very close.
What is the difference between exist and excist?
exist is = to be excist = nothing
How many times do mirrors reflect light and where is it reflected?
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.
Do the mirrors from Harry Potter exist?
The Mirror of Erised and the two-way mirrors are not real things.
Do fairies actually exist?
They do not exist.

Why quarks do not exist in free state?
Actually quarks can exist freely.
Does 100 percent pure aluminum exist?
Yes.
Does Mario paintball actually exist?
No
How many red pandas used to exist?
There was about 76 percent but now there is only about 20 percent.
Does herobrine exist in minecraft?
Herobrine doesn't exist,he is actually a Creepy Pasta
Do positrons actually exist?
If you're asking about positions, then yes. As a violinist of over 10 years, I use various positions in every piece I play.
Is the albedo of pencil lead closer to 0.1or 0.5 or 0.9?
Probably even lower than 0.1. Albedo is a measure of the reflectiveness of an object; perfectly reflective would be 1.0, while a perfect absorber of light would be 0.0. (Neither such objects actually exist, but some come close.)
Does mezelfxie actually exist on Pokemon platinum?
No
