If the universe is a 4d hypersphere then with a big enough telescope we could see into our own past, amirite?

Most people misunderstand the 4th dimensional representation of 3d shapes.

Imagine all of the universe inside a point like sphere similar to einstein's predictions

Instead of things exploding out, the size of the hypersphere is directly proportional to the entire timeline of the universe.

Similar to the hypercube, it's not actually a weird object that has lines receding inward from an outer cube. Its every permutation of the inner cube within the 4th dimension that can occur.

It's the only way to project a 4d shape into a 3d space that humans can begin to comprehend.

Im talking about a 2d shape living on the surface of a transparent 3d ball and be able to see his back kinda thing +1 dimension

That's why I went into depth about how these ideas are more complex than it may seem to be.

A 3d surface still has edges and vertices which would create near infinite pressure/drag on a 2d "being" that is moving along the 3d surface.

As for seeing your past within the hypersphere, humans have already done this by taking pictures and dragging those entangled photons into the future projection of the hypersphere.

As cool as that would be, it doesn't work that way. Quantum entanglement would pretty much mess up that view so it wouldn't be the proper vision anyway.

Damn science, being all complicated!

Also with the distances involved and the age of the universe, the earth would not exist 'back then'
