Plug in your laptop, fire it up, and watch the magic: thanks to E=mc², the whole rig is technically heavier when powered on than when it’s dark and dreaming in sleep mode. Capacitors charged, RAM churning, fans spinning (if your machine has them), all that stored energy adds mass equivalent to… a few stray atoms’ worth of cosmic irony. Your computer isn’t just computing; it’s reluctantly participating in relativity. Congrats, you’ve gained the weight of pure theoretical physics. Now go fill it with more data and pretend the scale noticed.
