Can you keep zooming in forever?

Here’s what happens when you just keep zooming in. Use code veritasium at https://incogni.com/veritasium to get an exclusive 60% off an annual Incogni plan.

A big thank you to Magnus Garbrecht from the University of Sydney for showing us around the lab and for his feedback on the script.

Special thanks to Quentin Ramasse for his expertise on the video.
