In a vacuum, the speed of light is at a mind-bending 300,000 kilometres per second. That’s as fast as it is physically possible for anything to move.

Todos nós conhecemos a regra número um do tráfego do universo - nada pode viajar mais rápido que a velocidade da luz. E ela é de 299.792.458 m/s. Mas por que é assim?

For the past 20 years causality violations and superluminal motion have been the object of intensive study as physical and geometrical phenomena. This book compiles the results of its author and also reviews other work in the field. In particular, the following popular questions are addressed: Is causality protected by quantum divergence at the relevant…
The speed of light has been long known to be the fastest possible speed in our universe. So what happens when scientists catch subatomic particles traveling faster than light?
While the theory of special relativity is often associated with the idea of traveling faster than light, this book shows that in all these cases subtle forces of nature conspire to prevent these motions being harnessed to send signals faster than the speed of light. The author tackles these topics both conceptually, with minimal or no mathematics, and quantitatively, making use of numerous illustrations to clarify the discussion. The result is a joy to read for both scientists familiar with the subject and laypeople wishing to understand something of special relativity.
“…a handful of dust trying to get back to supernova. Like every longing, everything alive.”
“There is also an amplitude for light to go faster (or slower) than the conventional speed of light. You found out… that light doesn’t go only in straight lines; now, you find out that it doesn’t go only at the speed of light! It may surprise you that there is an amplitude for a photon…

Quantum theory includes a "spooky action at a distance", which is now known to travel at a speed at least 10,000 times faster than light.
We all know the number one traffic rule of the universe – nothing can travel faster than the speed of light. But why is it so?
An experiment claims to have invalidated a decades-old criticism against pilot-wave theory, an alternative formulation of quantum mechanics that eliminates the most baffling features of the subatomic…
