Secrets revealed: Light’s faster speed’s impact | What if light travels faster than it is now?

According to Einstein's special relativity, the speed of light is considered an absolute constant and the ultimate speed limit in the universe. Objects approaching the speed of light would experience infinite relativistic mass, requiring infinite energy to accelerate further, making it impossible to surpass this limit. However, hypothetically increasing the speed of light to infinity would have profound consequences.

One consequence is the alteration of our perception of time and causality. Currently, distant objects appear as they were in the past due to the finite speed of light. If light could travel infinitely fast, events once outside each other's "light cones" could be causally connected, leading to confusion about the sequence of events.

Moreover, the expansion of the universe would change drastically. Currently, distant galaxies appear to recede faster due to the expansion of space itself. However, there's a boundary called the vision horizon beyond which light can never reach us due to the expansion velocity exceeding the speed of light. Increasing the speed of light would push this horizon further, expanding the observable universe and making previously unreachable celestial objects visible.

In summary, if the speed of light were infinite, our understanding of time, causality, and the universe's structure would undergo significant revision, leading to a profound reevaluation of fundamental physics.
