I'm glad I peeked at the video, because the title doesn't describe what the video shows.

It should be what if light from a star was concentrated into a 1m wide beam. Not, what if ALL visible light was a single beam. Those are two very different ideas.

I kept trying to turn the video to landscape to watch it properly. I never watch any vertical video apps so it confused me for a second to realise I was watching vertical video 🤢
