Do they remain in the air for a while then pop up in someone else's head, do they disappear for good, or does something else happen?
I love this as a #worldbuilding exercise, like somewhere there's a planet populated by half-baked ideas for creatures, monsters from children's imagination, discarded characters from novels and long forgotten imaginary friends. They would have the most fantastic buildings, culture and technology we could dream of (and have). What would that place look like? What would they eat and what is their main source of entertainment? What are the kind of problems the inhabitants would have?
Either someone will come up with them again, (not necessairly the same person, and if so they might claim that they were the first who did so.) or not. And if they do, then either they will forget them, or not, if they do not, then might try them or not, but nethertheless they had an impact on them.
Let me know if somebody comes up with the right answer. I've had so many awesome ideas float away just because I was too lazy or forgot to write them down... Then again, were they that good if I didn't think to record them in the first place?
I imagine much like where everything I forget is... somewhere, SOMEWHERE in my mind (I'm sure of it), but you don't really know. It's been filed and lost by the worker bees of my brain. Maybe someday it will be stumbled upon once again, but who's to know? One day, perhaps someone else brings it up and I'll say, "Oh yes. I thought of that, once." But I'll be too busy with other ideas and things. Also, if anyone can tell me where I've put my brand new Birkenstocks... that would be grand.
It is. There isn't really such thing as just "energy," though. It comes in many different forms. Kinetic, potential, nuclear, thermal, ionization, and so many more. From wikipedia:a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed.[1] The "ability of a system to perform work"
Physical is generally accepted to mean "tangible," i.e., something which one is able to touch and feel - over physical as "part of physics." I agree, it's just - odd for me to see the word "physical" used to mean, more esoterically, "relating to or of physics." I'm sure both meanings are correct, but one is more common.
