Why Our Understanding of Distance in the Cosmos Is an Illusion | Looking Through Time Itself

Описание: Why Our Understanding of Distance in the Cosmos Is an Illusion

We look up at the night sky and assume we’re seeing the universe as it truly is—but what if everything we know about cosmic distance is fundamentally flawed? From the stretching fabric of space to the way gravity bends light, our measurements are tangled in layers of deception. We’re not just looking across space—we’re looking back in time, through warped lenses, into an expanding void that defies simple definition. Even the tools we use shape what we see, making our maps of the cosmos more illusion than absolute truth. This isn’t just astronomy—it’s a profound rethinking of reality itself.

What part of the cosmic distance illusion surprised you the most?
