It turns out there are several ways things can travel faster than light, depending on what you mean by a “thing,” “faster-than-light,” and “travel”.
How To Build A Black Hole
Hypothetically, how would you build a black hole?
Does the Aether Exist? Hint: No
An interesting aspect of science history is that you can see how theoretical ideas rise and fall based upon the evidence. Models are proposed, experiments are made disproving them, and then the hammer falls. One such idea is that of the luminiferous Aether.
The Brilliance of Scientific Assumptions
How extrapolating beyond simple scientific facts takes our understanding into uncharted waters.
What If Light Had No Speed Limit?
What would the universe be like if the speed of light were infinite?
Lift You Up
It’s often said that planes fly thanks to the Bernoulli principle. In fact, it’s a bit more complicated.
Metamorphosis
We’ve long had indirect evidence that different types of neutrinos can oscillate into other types of neutrinos. We now have direct detection of this effect.
Time’s Arrow
In physics events are often time symmetric, so why is it that time so clearly seems to have a specific direction?
At Least There Is Symmetry
When an object absorbs light, it must have been emitted by something earlier. Does that mean when light is emitted it must be absorbed?
