On one hand, the speed of light is just a number: 299,792,458 meters per second. And on the other, it’s one of the most important constants that appears in nature and defines the relationship of ...
Let’s explore how constant this speed of light fundamental constant really is. One of the most fundamental physics facts is that the speed of light in a vacuum is constant for all observers. But can ...

The universe’s speed limit exposed and why even light is trapped
The universe comes with a built‑in speed cap, a hard limit that shapes everything from how stars shine to how cause and ...

Jan. 29, 1838: The birth of Edward Morley
Edward Morley, born Jan. 29, 1838, is perhaps most famous for an experiment that didn't work. The speed of light is one of ...
You won't go broke betting on Einstein's ideas to hold up. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Albert Einstein's theory of special ...
We wouldn’t notice. Or we’d die. Depends on how much it changed. Relativity already tells us what would happen if the speed of light were to change, and the answer is nothing. Consider a stationary ...
Scientists who believe in evolution don't like the idea of a variable speed of light, because it throws all dating efforts based on present conditions extrapolated to the past out the window. The rate ...
The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...
(via PBS Space Time) One of the most fundamental physics facts is that the speed of light in a vacuum is constant for all observers. But can we really be sure that the speed of light wasn’t different ...
In 1887 one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of the Earth by comparing the speed of light in ...
