If the big bang happened 13.8 billion years ago, and the universe is 93 billion light years in diameter, how did the universe expand faster than light?
In: Physics
basically the speed of light is the speed limit for “information” to travel through the universe. Think of it as anything that could be measured is considered “information”
Space itself is nothing, so it doesn’t count as “information” and can then pass the speed of light.
Another example is if you take a giant pair of scissors with light-year long blades. If you close the scissors at any speed where it takes less than a year to close, then the point where the blades touch will move along the blades faster than the speed of light.
The point itself is not anything that could be measured so it is “informationless” and can pass the speed of light”
I don’t know how much that helps, it’s how it was explained to me though.
