According to the theory of relativity, specifically the theory of special relativity, there is no universal "now" moment that applies to all observers. Simultaneity, or events happening at the same time, is relative and depends on the observer's frame of reference. This means that different observers moving relative to each other may disagree on the ordering and timing of events.
In special relativity, the concept of the "light cone" is used to describe the relationship between events and their causal connections. The light cone consists of two parts: the future light cone and the past light cone. The future light cone represents events that can be causally influenced by the given event, and the past light cone represents events that could have causally influenced the given event. The boundary of the light cone is formed by the paths of light rays emitted from the event.
Outside of your light cone, there are events that are not causally connected to you, meaning that you cannot influence them and they cannot influence you. The ordering and timing of events outside your light cone can be perceived differently by observers in different reference frames. However, it's important to note that the laws of causality are still upheld, even though the notion of "simultaneity" is relative.
In summary, outside of your light cone, events can occur in different orders and at different times according to observers in different frames of reference. The concept of a universal "now" moment is not applicable in the theory of relativity, and our perception of events is influenced by our relative motion and the finite speed of light.
