What is the definition of Estimation Experiments?

Estimation experiments are like the cosmic version of a magic trick, but instead of a rabbit in a hat, we're trying to guess the weight of the universe or the exact age of the Earth. It's a scientific way of saying we're trying to guess things without actually doing the work, like when you estimate how many jelly beans are in a jar but end up with zero or 200, depending on your imagination.

Now, here's a sentence that might make you think twice: "After the estimation experiment on the number of jelly beans in the jar, we all decided to start our own circus, but this time, we were estimating the height of the moon instead."
