The Thought Experiments That Fray the Fabric of Space-Time

Three thought experiments suggest that the space-time continuum we seem to inhabit is not fundamental but an approximation of something deeper. One shows a minimum length scale exists. Another reveals no physical property can be perfectly measured. The third highlights a mysterious property of space: its information capacity is less than expected. These experiments suggest space-time may not be fundamental.

Note

a rather compact approach with visualizations to outline why the chatter around "we are living in a hologram" is seemingly more prominent in todays discussion about what is reality.

one open question remains, beyond knowledge of reality, what impact does living or not living in a hologram have on our perceived reality?
