The Future 🤔: What If Time Travel Is a Computed Possibility Rather Than Physical Transportation?
__ She is standing on an empty stretch of concrete. Nothing here but cracked pavement and weeds pushing through the seams. She puts on a pair of lightweight glasses and the concrete dissolves. A porch appears in front of her — wooden steps, a rusted railing, a screen door hanging slightly open. The smell of rain drifts in from nowhere. She knows this porch. She kissed someone here forty years…
A woman stands on a desolate stretch of concrete, which transforms into a porch with wooden steps, a rusted railing, and an open screen door. The scent of rain envelops her as she recalls kissing someone here forty years ago, before the lot was turned into a parking lot and the building was demolished. The woman realizes she hasn't traveled through time; rather, the time has traveled to her.
For a century, people have imagined time travel as a physical displacement, but physics has not provided a clear solution. Instead, the focus should be on building a projector rather than a Delorean, as time travel is a compute problem rather than a physics problem.
We've been doing a primitive version of time travel in our heads since birth. Our hippocampus doesn't store memories as video files but reconstructs them using fragments like smells, sounds, and doorframes. Time travel devices essentially externalize this cognitive process, placing it in the physical world through augmented reality (AR) and artificial intelligence (AI).
The technology behind time travel is not new; cities use digital twins for flood modeling, archaeologists use AR to visualize historical sites, and museums generate AI dialogue with historical figures. The challenge lies in recognizing that AI-generated reconstructions are based on educated guesses and may miss the anomalies and unique details of the past.
The future presents a similar issue, where AI predicts what could become based on existing data, creating an average representation instead of the true, distinctive history.
