Pro Tip 1/3Time Alignment
Use 'simultaneity' when emphasizing that events are aligned in time, often unexpectedly.
She marveled at the simultaneity of falling stars lighting up the night sky.
Pro Tip 2/3Unexpected Overlap
'Simultaneity' can suggest surprise when two events occur together without planning.
Witnessing the simultaneity of two rare bird species appearing at once was extraordinary.
Pro Tip 3/3No Causation
Remember that 'simultaneity' does not imply one event causes the other; it's just timing.

that program you're seeing in the corner, if you spread it out, it's all these things all at once. It's real simultaneity. It's nothing we're used to working with. We're so used to working in one vector. This is all at the same time. The computer lives in so many dimensions. And also, at the same time I was frustrated,

Lee Smolin
American Physicist
There certainly is a tension between the relativity of simultaneity and non-locality in quantum theory, but it's not strong enough to add up to a falsification of either side by itself.
Quote examples
Walther Bothe
German Physicist
To demonstrate this simultaneity is by no means trivial, because it may for example happen that the product nucleus always forms in an activated state at first.
Quote examples
Roman Jakobson
Russian Scientist
Every linguistic sign is located on two axes: the axis of simultaneity and that of succession.
Quote examples
Robert Delaunay
French Artist
Simultaneity in light is harmony, the rhythm of colors which creates the Vision of Man.

The idea of the vital movement of the world and its movement is simultaneity.
