Made up, and then confirmed with experimentation against actual reality.
Let’s not pretend science is literature with extra steps. It’s a process whos aim is to confirm things in a way that removes all possible alternative explanation or influence. A good experiment completely and fully removes the human element.

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.

And now we have direct photographs of planets around other stars.

I guess you are referring to the c9ncept of dark matter?
To anyone who does not know what dark matter is:
Dark Matter is the “solution” for differences in the real gravitational force a star has and how much gravity it should have based on calculations. Dark matter basically is matter that does not interact with light in any form (and therefore can not be detected) but still emits gravity.

Not “gravity a star has,” but the motion of stars around/near galaxies. It is the general motion of groups of massive objects that hints that there is a lot more mass ‘around’ most (not all) galaxies than what matter we observe could possibly account for.
