Cosmic censorship hypothesis - Wikipedia
I predict when doing this experiment that the higher we drop the ball
from, the higher the ball will bounce to, because more potential
energy is gained from a greater height and therefore it will have more
at the surface and may bounce higher but energy is
still lost to heat, movement, sound and speed, therefore the ball will
never reach its original height that it was dropped from, when no

Here are three experiments to illustrate when the different approaches to statistics are appropriate. In the first experiment, you are testing a plant extract on rabbits to see if it will lower their blood pressure. You already know that the plant extract is a diuretic (makes the rabbits pee more) and you already know that diuretics tend to lower blood pressure, so you think there's a good chance it will work. If it does work, you'll do more low-cost animal tests on it before you do expensive, potentially risky human trials. Your prior expectation is that the null hypothesis (that the plant extract has no effect) has a good chance of being false, and the cost of a false positive is fairly low. So you should do frequentist hypothesis testing, with a significance level of 0.05.
A useful first hypothesis is that the potential function
is shaped like the sum of two inverted cosines, with one having a
minimum at 0 (= 1) phase and the other having a minimum at both 0 and
0.5, as shown in Figure 3A.
