Wouldnt that make it the speed of light? , because thats all darkness is, is simply a reaction (or lack thereof) to light.

There is no darkness, only lack of light. So therefore darkness has no speed...

Yes, it was a bit of humor.
However, if the understanding of light is that it travels at 186,000 miles per second, then when a light bulb is shut off, the last tail piece of the light is followed by the presence of darkness at precisely the same speed as the light it follows.
But after the light is gone, does the dark really move at all?

so why don't we see the sun light passing the earth?

Does darkness cancel light? yes.
You can't have one without the other and neither can one be more powerful than the other.

Galaxies today are struggling to clump together against the incredible repulsive power of dark energy, hints a new survey of thousands of galaxies. Measuring this anti-clumping effect puts a new arrow in the quiver of cosmologists seeking to uncover the nature of the mysterious force.
Scientists proposed the existence of a mysterious repulsive force called dark energy in 1998 to explain supernova observations showing the universe is expanding at ever faster rates.
Since then, researchers have been trying to measure the properties of dark energy more precisely, in the hope of discovering what it is. Possible explanations include fluctuating energy fields from quantum physics and the effects of unseen extra spatial dimensions.
Dark energy: Seeking the heart of darkness,
There is no way to detect dark energy directly, so we have to measure its effects. The most obvious of these is the one that gave it away in the first place: the way it forces the expansion of the universe to accelerate.
Although dark energy is a ubiquitous term in cosmological conversations, no one actually knows what it is. Although there are plenty of tentative explanations, each one seems to suffer from some fatal flaw. The simplest of the solutions on offer is the so-called cosmological constant. This is an energy associated with space-time that was originally invoked by Einstein in his equations of general relativity.
"Dark energy could be the ether of the 21st century,".
"We are definitely seeing something extra in the universe, we just do not know how to interpret it yet,".
