Why would'nt this work?
-
Photons don't have mass, but they do have momentum.

-
AlphaPhoenix is definitely one of the best scientists on YouTube, that video is good.

Iirc from the 2 YouTube videos I watched light can theoretically bend thanks to gravity, black holes anyone?
-
Username checks out.
-
Relativistic mass is not helpful to our everyday understanding of mass, it's more helpful to discuss momentum, like the other commenter pointed out
-
Space bends due to gravity. Light continues in a straight line through the now non-linear space, thus appearing to bend.

This is actually a great example for why that stick must not exist.
You can also do this with a unbreakable stick and an unbreakable shorter tube. Throw the stick at a high velocity through the tube and it contracts for the point of view of the tube. Then close it shut. Now you have a stick that's longer than the tube fully contained in it.

Go find a 30' stick and let us know if you can point it at the moon.

Correct answer is here.
-
I think the standard model says the same thing, tbh....
-
Basically the speed of sound in that material
-
I predict we'll have FTL travel before we can invent a stick that's "unfoldable".
