The Sun could reduce the activity by 90%, and the planets get 10x closer to compensate the reduced light.


Interesting how a star can be "ejected" from a galaxy :

Sorry, I cannot think of a better place to put this, just not the last thread to which I was responding, which was someone else's:

I have been listening to comforting cadences as I work.

Arguably, "The Spooning Song" isn't a cadence. It did not help me work.

The next one was "Baby Marine." I always have difficulty with the first line: "Talkin' to my daddy on his dying bed."

I wasn't able to say goodbye to mine until he was cold.

I hope that everybody is having a great day.

Allow me to introduce the Inverse Square Law: "the intensity of an effect such as illumination or gravitational force changes in inverse proportion to the square of the distance from the source." https://www.lexico.com/definition/inverse_square_law

So, if you are twice as far from a source of light, noise, or other radiation, you receive one-quarter as much energy. If the sun decreased its output by 90%, planets would need to get 3.16 times closer to to compensate.

You are absolutely right.
I made the comment so fast I forgot about square meter law, a so basic thing.

I just used the proportion relation of size variation (like height/diameter of Moon or SUN) and distance, but forgot to consider both dimentions to make the calculation.

3,1262277660168379 times closer to be more exact.

Don't recall where I snagged this from:

"if you leave enough hydrogen long enough, it'll begin to wonder why it is there. We are Universe experiencing itself.
"


Maybe Slashdot's UNIX fortune cookie?
