In the time of the dinosaurs the Earth rotated once in 17 hours rather than about 24 hours, where did the rotational energy and angular momentum go?
Then 1 part in 6 billions doesn't produce a 1 (or 12) part in 12 (or 1) billion when squared. So i guess you have to divide your P by 36. Which is still off by a factor of 3 according to wikipedia (P=3.3TW) That goes along David's correction to increase the effect from 1.4 to 2.3ms/day/century

Double-double-slit with entangled photons
your question is a big confusing mess. But you should first understand that the pattern for A photons will not depend on what you do to B photons.

it seems obvious the rate of slowing depends on the distance between the moon and the earth and their difference of angular velocities. For short distance and greater velocities difference the torque is greater. So with time this deceleration decreases ... till the moon is in phase with the earth and would not seem to move anymore. By the way the numbers are wrong: 0.005s/year/year = 1.5 10^-10 / year

Kettlebell squats center of mass
weights on your shoulders will travel a greater distance (difference of height) than weights on your chest during a squat. So you have to work harder with weights on your shoulders. This is angular momentum law. If you feel it is easier it might be because you use different muscles

Has this experiment really demonstrated wave-function collapse?
Ok i think i understand what your disagreement is about now. Of course standard QM predicts correctly their measurements! The purpose of this paper is not about demonstrating one interpretation or another one. They use the word "collapse" just to say that the result of Alice measurement projects Bob's state. They did the steer thing with one photon which is very nice. But there's nothing more fundamental than doing it with two entangled spin for example. Also, doing it with one photon has a historical meaning as explained in the abstract. Hence the reference to EPR

In the article you have: a|3>|4>+b|4>|3> -> (c|3>+d|4>)(e|3>+f|4>) It fits your definition of collapse if you take |1>=(c|3>+d|4>)(e|3>+f|4>) and |2> accordingly. So yes you can call it collapse (even if you only measure one part).

Why does the bathroom become hot after a bath?
Indeed you feel more the heat (or cold) when air is wetter. But there might be a way the temperature increases if the shower brings small drops of water or vapor in the air due to the water pressure. These smalls drops or molecules will condense on the floor and on the walls. This causes the temperature of the air to increase. I can explain more if you need. It's the same process that increases temperature when it starts to rain.

Does a photon travel in all directions?
if you stare at the sun then the photons go directly in your eyes (in straight line).
