I have been trying to study special relativity. However, I do not have the mathematical knowledge to understand any technical explanations. I started reading A Brief History in Time and I thought I should have some background knowledge on this special relativity Stephen Hawking was describing. So I went online and did a bit of research and I found out about the following:
If there are two observers, Observer A and Observer B, they will agree on the following:
- Space time interval between two events
While they do disagree on these:
- Time of an event
- Space of an event
- Order of events
However, disagreeing on these factors does not mean they are wrong, both are right.
That means that if I have three events: Event A, Event B, Event C. They can take place in this order: A, B, C. However, it was explained that they can also take place in the order: C, B, A.
My confusion lies in two questions:
How can the order of events be C, B, A if we assume that event B was caused by event A, and event C was caused by event B, then wouldn't the order of event be forced to be the same every time due to causality?
How can observers disagree on the order of events and we don't notice? I am having problems visualizing how this could apply to the real world? Is it just at a microscopic scale so we can't really notice the change of events?
I am a beginner in the topic of special relativity so I apologize for any lack of understanding on the subject.
