Isn t it so that something that flashes in front of your eyes can also be perceived

It depends on how fast it is, for example, if it is "supersonic", it will not be perceptible.

Yes, human senses are very acute.

It depends on how fast that thing is.

Of course it is impossible.

1.It depends on what your "thing" is. The human photosensitive frequency is 5 10 (14) 5 10 (15) hertz, and the light above or below this frequency is invisible, so the luminous body or the reflector of this light is invisible.

Similarly, the intensity of the light also has a big impact.

2.I'm sure you've all heard of "visual retention". It is the phenomenon of visual persistence.

The most important principle of cinema is "visual persistence". Scientific experiments have proved that the human eye can still make the image stay on the retina for about two seconds after the image disappears.

It depends on whether it is something you know, and if it is something you are familiar with, it will be easier.
