1. If Big Bang really happened, then what are the action and reaction forces acting? 2. A quantity like Entropy is always increasing. If average temperature is made constant then universe is getting heated continuously..then what is that being cooled? 3. Total of action and reaction force =0, if that's true then why universe getting expanded day by day? 4. Some say that action and reaction force both can not be equal at same time instant..is that true? 5. In EM field Newton's 3rd law fails totally! So, in our universe, this is a dumb! 6. Adding a link....Explain me why its happening? http://www.animations.physics.unsw.edu.au/jw/Newton.htm 7. What are action reaction forces in black hole?
