“Did time exist before the universe?”
That question depends on how we define time and the universe.If we define the universe as all that exists, including space, matter, and time itself, then time began with the universe—it didn’t exist "before" because "before" implies time already existed. This aligns with standard interpretations of the Big Bang theory, where space-time itself emerged from the initial singularity.
However, if we consider the possibility of a larger reality beyond our universe, then time could have existed in some form before our universe came into being. Some speculative theories, like eternal inflation or cyclic cosmology, suggest that our universe may be just one phase in a larger, ongoing process.
Ultimately, if time itself is a property of our universe, then asking about "before" the universe is like asking what’s north of the North Pole—it’s a meaningless question. But if time is part of a greater cosmic structure, then something may have existed before.
