The general consensus is that Newton was the greatest scientist
who ever lived. I am fine with that.
It's interesting though that there are times when great scientists
do mediocre work, and times when mediocre scientists do great
work. In the 1920's it was a great time to be a scientist due to the
emerging nature of quantum and nuclear. But these days it's very
thin gruel for everyone.
No one is denying Newton’s contributions to physics and mathematics, and he was indeed a pioneer, but this whole “greatest scientist of all time” thing is nothing more than your ego talking.
Einstein, Planck, Hubble, and many other of the early 20th century have contributed to knowledge of science, in their respective fields.
And we know more today than those of the 1920s, and 50 years from now, they would know more than this generation. It is called progress, PruePhillip.
As much as Newton was a giant in his time, he didn’t know everything. Einstein didn’t know everything. No scientists know it all.
Science isn’t about knowing everything.
Science is about being able test knowledge - testing the hypotheses and theories - to find out which of them are probable and which are improbable, through testable evidences.
Any current accepted theories can be questioned or challenged, and any theory can be replaced, and there are no exception. But these challenges must undergo rigorous testing too.
You clearly don’t understand the concept of science.
