Illustration about the "relativity" of light

I just found this on the internet. It reminded me of a joke I once made:

It's a nice illustration about the "relativity" of light - kudos https://www.linkedin.com/in/james-o-donoghue-astronomer/

That’s really quite a good way to show the true speed of light without it winking past you.

I’ve never seen this demo before.

Here is the spatial version a member of ours has made:

That’s pretty awesome too. I couldn’t get past Mars though as the web page would get reloaded and I’d be back at Mars again.

I agree. That's very useful. We all need analog reference calibrations in our heads to truly understand. For a car, how fast is "slow" and how fast is "fast"? We lack that in daily life for light speed. The number of light years to distant stars is symbolic knowledge, not an analog calibration.

Understandable analog calibrations are what those videos provide. Thanks for sharing @fresh_42

Click on the Mars symbol at the top.

I clicked on Saturn or any higher planet and the web page fails. I think it’s trying to continue loading everything for the effect of moving through space and overwhelms my browser.

But it’s still quite impressive like the Eames Scales video of the 60’s.
