Shooting stars
I want to see a shooting star. If you happened to see a shooting star, do not wish for what you want at the moment, coz' it is just not going to happen.
Reason being:
Let's imagine the meteor shower is from the commonly known perseid showers. The perseids are a prolific meteor shower associated with the comet Swift-Tuttle. The Perseids are so called because the point they appear to come from, called the radiant, lies in the constellation Perseus. Meteor showers occur when Earth moves through a meteor stream. The stream in this case is called the Perseid cloud and it stretches along the orbit of the Comet Swift-Tuttle. The cloud consists of particles ejected by the comet as it passed by the Sun.
Enough of rubbish, so the point i was trying to make is, since the showers orginated from the radiant, Perseus system. It is approximately 93 light years away from planet Earth. And according to the theory of relativity, nothing could possibly travel faster than light.
So, if god happened to be nice and grant your wish. Okay, god is always nice and grant your wish. It will take god at least 93 + 93 = 186 years before god can reach to you. (ie. If only god travels in the speed of light. Just like Jesse and James from Team Rocket)
Understand?
That's why if you wish for 50bucks to drop to your feet, it doesnt happen immediately, perhaps XX no. of years later, 50bucks indeed fell from heaven. Just that it wouldn't be your feet.
