Planck length and Planck time are constants, correct?(adsbygoogle = window.adsbygoogle || []).push({});

If spacetime changes for an observer who accelerates to subluminal velocities, what happens to these units? If they're constant I'm guessing they can't be "stretched" or "squashed". So do they change in number for a given measurement (say, the length of a pencil at rest) as you accelerate?
