Einstein defined simultaneity using the instants in time we detect the event.
The concept of“Now” doesn't make much sense, as we saw, when we speak of an event happening in the sun,for instance. Simultaneity is relative.
Einstein instead redefined simultaneity by using the instants in time we detect the event.
This fact may not be noticed in the case of trains and aeroplanes,but when it comes to cosmological distances, simultaneity really doesn't make any sense.
On the other hand, if we define simultaneity using concurrent arrival of light, we will be forced to admit the exact opposite.
Not only have we no direct intuition of the equality of two periods,but we have not even direct intuition of the simultaneity of two events occurring in two different places.
Another way of defining simultaneity is using sensing- we can call two events simultaneous if the light from them reaches us at the same instant.
When we say that two periods are equal, the statement has no meaning; 3 Not only have we no direct intuition of the equality of two periods,but we have not even direct intuition of the simultaneity of two events occurring in two different places.".
In fact, since it takes time for light from an event at a distant place to reach us, and for us to become aware of it, the concept of‘now' no longer makes any sense, for example, when we speak of a sunspot appearing on the surface of the sun just at themoment that the astronomer was trying to photograph it. Simultaneity is relative.
