I saw a theory by some physicists that there is some evidence we may be a hologram but I'm not smart enough to understand exactly what that means. Sounds neat

I'm also not smart enough to understand it completely but I think they meant something strange could be happening with dimensions (think Flatlanders) rather than us being a computer program. anyone with more understanding please elaborate tho

There's an argument that because some of the physical limits we see around entropy density (due to singularities) are proportional to the area of a sphere around the volume, together with math indicating it's possible to translate physics in a 3D volume to a 2D surface, the whole universe might be a projection from the 2D surface of a sphere

It's a hell of coincidence that this is the second time I heard of this, the first being 2 days ago in a video game. Said video game is full of crackpot conspiracies though.

Yeah that doesn't mean we're running on an alien projector. Science communication of theoretical physics is horrible.

Anytime you find yourself getting excited about some galaxy brain SciFi stuff just clap out some chalk board erasers and inhale the dust. That's about how pleasant and exciting theoretical physics is (and how worth doing, fight me you keyboard tapping nerds) and it should help you get in the mood for appreciating findings.
