•Well tested predictions can’t change much
–Newton’s
“apple”
–Planetary
motion
•Newton’s sky
predictions vs. Ptolemy’s
•Einstein’s
position predictions vs. Newton’s
•
•The “why” of events can change radically.
•
•Can have radically different predictions in untested
areas:
–Elliptical
comet orbits from Newton (Halley’s
Comet)
–Bending of
starlight from Einstein Relativity
(Black holes)
–“Orbits” of
electrons in atoms from Quantum Mechanics.
