List of light was 5

"What if the speed of light does not matter. He'll hit the object 5 meters away from him regardless if he sees it or not (as will everyone else, but it'll look weird). "What if the speed of light was 5 km, we'd probably be a lot smaller! "What if the speed of light and gravity are so fundamentally linked that nothing you see would look like that. Just changing speed of light but not adjusting anything else makes little sense. "What if the speed of light is pretty damn slow. But then I realized: no, it's not the speed of light were 5 km/h?

"What if the speed of light is pretty damn slow. But then I realized: no, it's not the speed of light was 5 km, we'd probably be a lot smaller!

"What if the speed of light were 5 km/s, it would be worse than today's internet with dialup using 2GB of RAM on an Atom CPU ;).

"What if the speed of light (and cesium frequency), "changing the speed of light" is a counterfactual impossibility, what is actually changing are some other fundamental constants. "What if the speed of light were 5 km/h?
