What if speed of light was 761 MPH?

Answer 1

The visual and audio components of an event would reach you at the same time regardless of distance. For example when you see lightning strike in the distance, and it takes awhile to hear the thunder. If light traveled at 761, you would see, and hear it simultaniously.

Answer 2

If the speed of light were 761 mph, it would dramatically change our understanding of physics and the universe. This speed is much slower than the actual speed of light in a vacuum (approximately 670,616,629 mph), which would impact a wide range of scientific principles and calculations, including relativity and the nature of reality as we currently understand it.
