It’s still possible we all live inside a hologram

Is our universe actually just a hologram? This idea has been floated around before, and isn’t just some trippy, somewhat horrifying thought one gets at 3am, perhaps along with (or as a result of) insomnia. Instead, it could very well be an actual physical property of the universe. And it may have been under our noses all this time.
Mathematicians are already familiar with the holographic principle, which the famous physicist Leonard Susskind first proposed. It asserts that a volume of space can be thought of as encoded on a boundary to it — such as an observer-dependent gravitational horizon — and therefore needs one less dimension than it appears to need. By extension, since our universe seems three-dimensional to us, it could actually be a two-dimensional structure that’s overlaid onto an incredibly large cosmic horizon.
