“Yes, I know and your point is?”
Back to my original response:
“There’s been attempts to modify Newton in the past. I remember reading an article on such an attempt in Science back in the 1980s. All came to naught, “
Einstein “modified” Newton over a century ago.
I am not disputing that. So, what’s your issue?
But there have been attempts to show it breaks down in nonrelativistic domains.
