It came from the Labratory of The Mind, yes, the work was entirely metaphysical, but here’s the wierd part. They used that mental experimentation and applied it to real life action, and it worked. It’s like imagining you have a magic carpet for years then you stand on one and it starts flying. It began as imagination of the world around us, then when checked against reality. It works. Someone figured out that if something was passing around a sun. A planet, that it would dim the light at regular intervals. They checked, it did, that’s the only reason we know there’s planets outside our solar system. Someone checked the lumens of stars and found the data matched the theory. We use the color variations of stars in a similar way to detect more data. It’s quite remarkable. A recent discovery in gravity is that while gravity is a ‘‘constant’’, it actually fluctuates from place to place, I’m not sure if anyone figured out why yet, but if and when, how they find out, will be their imagining a reason, imagining how to check, checking in real life, and getting the data on if it’s right or not.
