Let us take a simple and generally accepted law such as the law of conservation of momentum. Let us say we are dealing with a closed system and are ignoring extraneous factors such as friction and energy dissipation due to heat during the following collision:
We have two masses traveling in the...
"Black holes", physically, are extremely dense masses. How can one possibly fall into a "Black hole" ? Can one practice falling into a black hole by jumping into a pavement from a 10 storey building?
If the universe is expanding, then stars must be moving away from us. And as the red shift of a star is proportional to its distance from us, then the red shift of all stars must also be increasing. Is the red shift of any star increasing?
If stars are moving away from us, then they must be...
The intensity of light observed from a given source decreases as the square of the distance between the observer and the source. Hence, if stars are truly receding from the earth, the intensity of light observed from any such star should be getting dimmer as time goes by. But the intensity of...
