Interesting fact of the day:
Despite popular belief it is not really correct to say the speed of light is a universal speed limit in the universe. It would be more correct to say one object can never go faster, relative to another object by the speed of light.
In other words, no matter what speed I am going relative to the earth (or anything else) doesn't matter; if there is some object going the same speed and direction as me I can still accelerate up to the speed of light faster than it.
All that matters is that nothing can go faster than the speed of light relative to me the observer.

@freemo @Science is this a time dilation thing?
because intuitively if one thing is moving away from you and another thing is moving in the same direction, if you accelerate fast so that your relative speed is equal to the speed of light, is it possible to travel away from both of them at the same speed? and would that only be from your perspective so like, the relative speed by an observer who was traveling even faster than the other object you could be moving slower relative to all three things from their perspective because time would be going differently to them?
I kinda disagree. Personally I have always found special relativity highly intuitive even from a young age (in 4th grade i had re-discovered the equation for time dilation after hearing my teacher mention how it worked as a side comment once and it sounded like an easy concept).
I think intuition goes very well with it but you must learn to have a new intuition of sorts and think about what it is like in space where you have no points of reference around you to consider what is or is not stationary in an absolute sense.
IMO it doesnt start getting to be intuitive until you tack on general relativity, then things are a lot harder to reason through. Length constriction fo special relativity can be a bit unintuitive too, but even that I think you can build up an intuition rather fast once you understand a few things without the need for math or axioms.
