I mean if you have two light cones on a Cartesian coordinate system. E1 t=0 is at (0, 0) and E2 t=0 is at (8, 0). Obviously these two events are outside each other’s light cones but will cross as time passes. Does the crossing mean the E2 has influenced E1? How could it if it is outside the other’s light cone?

Wow, that was really great. I will now look for the mathematics behind the coordinate transformations that make it impossible for there to be a reference frame in which A & B are simultaneous and in which A & C are co-located.

It was amazingly concise and understandable. Thanks.

If something travelling at the speed of light experiences no time passing, how would something travelling at the speed of light minus the speed of light experience time? What would the opposite of no time be?

hello, I have one question. If there are many light cones at t=0, does it mean that although they will not influence each other at t=0, they must have an influence on each other as time passes? Is it just a matter of time?

[georgegreen]

why t' axis is not perpendicular to x' axis?

Many importand things left out... Rindler Horizons to give an example.

[rockyshepheard]

Can an event from elsewhere effect an event inside a light cone if you give it an infinite amount of time?

Why is light represented as a diagonal line on the diagram?

[flowwiththeuniverse]

If light doesn't experience time or distance, why does it have a numerical speed limit. Shouldn't it be instantaneously?

[zigzagzwag]

I just began my engineering degree and I'm still in college algebra. One day I hope to understand these concepts more intuitively and maybe get a null cone tattoo

[josephrichards]

Similar to existential philosophy of 'facticity'

Why am I watching this? Why did I search for this at the first place?

I'm sticking with an ice cream cone. This stuff is too confusing.
