Wait, I thought gravity is not a “force” but the curvature of spacetime, so at some point the curvature gotta end or be disturbed by some other source nearby, right? A star so far away is not exerting any “force” on me as I already have two massive objects Earth and Sun twisting the spacetime around me so much. I could however be getting some gravitational waves from that star but not sure how strong they’d be or if they reach me at all (again given Sun and Earth).

(NOTE: I’m an engineer not a physicist so my understanding could all be wrong)

Yes that’s good advice. Thanks.

I did that knot in front of a shoe saleswoman and she commented she had never seen anyone do that before. Asked me to show her again how I did it.

I don’t think you ever took even economics 101 in school because for almost all products there exists a price where you can actually increase your profits by decreasing the price because the larger sales volume offsets the revenue lost. Applies to your fridge example as well. You just assumed the same sales in both scenarios which is not even close to being realistic. And your Nvidia/AMD example ignores the high inflation seen during that period.

Which keyboard is it in the first picture?
