Consciousness Is the Fabric of the Universe
What if consciousness is not a product of the brain but the fundamental substrate from which all physical reality emerges? This theory explores a panpsychist framework where awareness is woven into the structure of spacetime itself.
We Are Almost Certainly Living in a Simulation
The simulation argument is not science fiction — it is a logical inevitability given the trajectory of computing technology. Here's why the probability we occupy base reality is vanishingly small.
The Block Universe: Time Does Not Flow
According to eternalism and special relativity, all moments in time exist simultaneously. The feeling that time "passes" is an illusion of consciousness. Past, present, and future are equally real — and equally fixed.

What would it actually feel like to be a Boltzmann brain?
A Boltzmann brain is a hypothetical self-aware entity that arises due to random fluctuations out of chaos in a state of thermodynamic equilibrium. In an infinitely old or infinitely large universe, such entities would spontaneously arise by chance — possessing a full set of false memories of a life that never happened. The terrifying part: you cannot prove you are not one right now.
Is dark matter just gravity leaking from parallel universes?
Randall-Sundrum models in extra-dimension physics suggest that gravity, unlike the other forces, is not confined to our brane but can propagate through the bulk. If this is true, gravity from nearby branes (parallel universes) would affect our brane while being otherwise invisible to us. Could this explain the observed dark matter distribution? The galaxy rotation curves seem suspiciously smooth for a gravitational effect from within our universe.
Can a philosophical zombie world exist? What would it change?
Philosophical zombies — beings physically identical to humans but with no inner experience — are a thought experiment designed to test whether consciousness is something over and above physical processes. If p-zombies are conceivable, does that mean they're metaphysically possible? And if they're possible, what does that tell us about the relationship between physics and experience?
