Not quite. Standard measures are only standard on earth. For example, as an object approaches the speed of light, its mass increases. A kilogram here on earth would have far, far greater mass in the spaceship approaching the speed of light. Even at considerably slower speeds, there would be a slight difference. Let's say that Mars was traveling at twice the speed of Earth around the sun. If we were standing on Mars, then a kilogram would have just a tad bit more mass than it would on Earth. (Remember mass does not equal weight.) In other words, the only way that standard measures have any meaning is if you define the parameters in which they are being used. Hence, even standard measures are relative. Einstein kind of destroyed the idea of an objective universe. Objective is entirely a human concept and does not exist naturally.
