Darkness, being the absence of light, has no speed at all.
According to astrophysicist Neil deGrasse Tyson and other scientists, speed fundamentally requires something to move. Darkness isn't a thing that moves; it's the lack of something (light). Therefore, the concept of the "speed of darkness" is a misnomer. You can think of it like this:
- Light is a presence: Light is made up of photons that travel at a specific speed (approximately 299,792,458 meters per second in a vacuum).
- Darkness is an absence: Darkness is simply the lack of these photons. It's not a separate entity "racing" against light.
Imagine a light switch. When you flip the switch off, light disappears, and darkness seemingly "appears" instantaneously. However, nothing is actually traveling to create that darkness. Instead, the source of the light has simply stopped emitting photons.
Here's an analogy: Consider a room filled with water. If you drain the water, the "absence of water" (the newly empty space) doesn't have a speed. The water has a speed as it drains, but the emptiness left behind does not.
In summary, because darkness is not a physical entity, it cannot be said to possess speed. The very question is based on a misunderstanding of what darkness actually is.
