Thoughts themselves don't have physical space, therefore our brains might actually be capable of limitless knowledge.
Hmm, do you have any evidence of that? 
Just a hypothesis I've been thinking of. Haven't tested it on account of sheer laziness. That and I'm not a scientist. But, if you think of how another archaic, analog device, the record player, works (the needle moves along the grooves on the record, which are etched in for the specific music recorded on it), you can't really say that the grooves in the record ARE the music, can you? Likewise, the sound waves that come from the music can not be touched, they don't have weight, but the effects of the sound waves are there in the vibrations of objects, particularly ear drums. There isn't a physical sound wave, but its presence, its effects, are known.
I imagine thoughts work on a similar principle. And, unlike sound, they can't be detected by any of the five senses, but we know their effects are real enough.
There is a physical soundwave. How else would it have measurable effects?
Physical in the sense that you can hold it? The measurable effects are really a displacement of air caused by vibrations in objects that play sound, but the objects themselves are not sound.
Are protons physical? Are planets? I can't hold either of those, in any meaningful way. Is light physical?
I think you mean "massive", in the sense of "having mass". But many very important "things" (probably better called "phenomena") are massless. Electricity. Colour. Sex.
Doesn't mean they're not real. 
, but it's pretty safe to say that a record is not music, right?
