We all travel through time at a rate of one second per second. Additionally, telescopes like the James Webb allow us to observe the past by capturing light from distant galaxies that took years to reach us.
While movies depict hopping into a machine to visit the past or future, current physics dictates that this kind of instantaneous travel is not possible.
Based on Einstein's theory of special relativity, time dilation suggests that the faster you travel, the slower time moves for you relative to a stationary observer. This effect is only significant at speeds approaching the speed of light.
Scientists have theorized the existence of wormholes, which are hypothetical tunnels through space-time that could potentially connect different points in time, though their practical existence remains unproven.
