Recently, I've been looking through some physic articles and found some equations of relativity. In those articles it was said that the relative mass varies depending on whether it's moving or not. So if a object is moving really fast it has more mass than a resting object.
The thing is, since we are moving through the universe at a really high velocity, could we say that the mass we can measure is actually higher than our real mass? Is the mass we can measure our real mass or should we use any equation to get it?
