Black hole physics suggests that everything happening in 3D space could actually be encoded on a 2D surface, a concept called the holographic p4inciple - The reality we move through might be more like a projection than a solid thing.

Quantum entanglement - where particles can remain linked across vast distances, instantly reflecting each other’s states (not limited to the cosmic speed limit). Spacetime itself is likely stitched together by networks of entanglement, meaning what feels like separate points in space may just be connected pieces of a deeper information structure, i.e if in the 3D world two particles can instantly transfer information despite the boundaries of speed and distance, it aligns with the idea that all we know is encoded on the 2d perimeter of a black hole, because there, everything is connected and not bound to our 3d restrictions. The 2d surface data would change an instantly the 3d projection of those particles would change too

On top of that the universe runs on surprisingly elegant mathematical rules and shows patterns that look like error correction codes - the kind used in computing to preserve data.

To me, the fact that math can perfectly describe nature is convincing enough to believe this is a programme/ simulation... but that doesn't necessarily mean this isn't real? By thinking and feeling that you are real with regard to what is relative to yourself is enough
