No....it is not some imaginary or unlikely concept. It is really true that the world we see, feel, hear and perceive is created for us in our mind.
No it isn't - it is merely your assertion.
Viruses perceive a different reality.
No they don't - viruses are unable to perceive anything using the accepted defining of perception.
Electrons would perceive a different reality.
No they don't - electrons are unable to perceive anything using the accepted defining of perception.
Strings would perceive a different reality.
No they don't - strings are unable to perceive anything using the accepted defining of perception.
Mechanistic interactions between entities (which viruses, electrons etc may have) isn't the same as perception which requires awareness - a virus or an electron may interact with something and that may cause an effect but is has no awareness that this has happened as neither have any consciousness.
The classical world is just one perception of reality at a certain scale. Independent of our mental processes what reality truly is, cannot be comprehended.
Baseless assertion.
This is not a speculative idea. It really is true!
Blimey uber-bullish baseless assertion. If this is true then I presume you will be able to prove this to be true with evidence.
Simply writing something down on a message board doesn't make it true.
Thinking something is true doesn't make it true.
Wanting something to be true (regardless of how much you really, really, really want it to be true) doesn't make it true.
