The same scenario would apply for a close family member, right? If your parent or sibling ended up in the hospital, do you go check up on them, maybe even cover their bill, expecting something in return? Well, if you do, you’re just plain evil. If not, no exchange will occur. This becomes a one-way market. Some people donate to charities because they want to help people or causes, not expecting anything in return.
Now there are people who will do those things expecting something in return. Hopefully you are not one of them.
Motion is described as the process of moving or being moved. People can be moved by your actions, whether in a positive or negative way. The impact happens. Again, I don’t want to discredit what you know, but Isaac Newton’s Third Law of Motion does not apply here.
For those of you who are not familiar with this law it states that “For every action, there is an equal and opposite reaction.” For you science buffs out there, this means that when two objects interact with each other there are two forces that will oppose. An example would be, when you sit down on a chair, you are applying downward force, while simultaneously the chair is pushing you up. These two forces are called the action and reaction forces. His theory states that every force comes in pairs. The size of both forces are equal but the direction of the forces are opposite.
With that in mind, his lessons apply to Physics, which is a study that involves matter’s motion through space and time. That’s about as Star Trek as I’ll go, but you needed to know that before I continue explaining.
You and I are both matter, moving through time and space.
Something else that is matter, is currency or what you think is money. Equal and opposite forces would be me going to the store and buying something with my money. I’m gaining whatever I purchase while simultaneous losing the currency of which was used to pay for it. The only thing that remained constant was value, which in my mind, the two were of equal value. If the two were not of equal value I would not have bought it. But how often do you buy something that you believe is of the same value of what you are paying for it? Generally, it either cost much more than you anticipated or you believe you bought it at a bargain.
