Doesn’t time ‘go forward’? Modern physics explains

Time is still an intensely debated topic in science. After all, even Albert Einstein explored and tried to understand the concepts of the fourth dimension of the universe; Scientist and scientific popularizer Carl Sagan said that space-time could be the fourth dimension.

Scientists believe that our minds Since we cannot understand the concept of real time, our brain creates a ‘beginning, middle and end’ line to explain what is happening around us.

In an article on the website SpeechSpanish professor and researcher Alberto Casas González from the Institute of Theoretical Physics (IFT – UAM – CSIC) points out that modern physics can explain why time does not ‘go forward’. This means that time may not be exactly linear as people perceive it; Perhaps the perception of the past and future is a concept created by our mind.

According to Albert Einstein’s theory of general relativity, space and time are relative because they depend on the speed of the observer and the gravitational field around him. In the psychological perception of human beings, the past has already happened, the future has not yet happened, and the present is the only real moment of existence. Despite, physics equations do not show this; this is just our limited perception.

“Einstein’s theory of general relativity (1916) again makes use of four-dimensional space-time, but also includes gravitational effects. Gravity is no longer thought of as a force, as in the Newtonian system, but as the cause of the “deformation” of space-time; it is an effect clearly described by a set of equations formulated by Einstein,” explains the encyclopedia Britannica.

Time ‘doesn’t go forward’

González states that there is no type of equation that suggests that time flows like the past, future and present we perceive. The scientist suggests that the way we feel the passage of time is probably a kind of illusion created by our minds.

According to modern physics, time seems like a complete and unique thing. It’s as if the entire history of the universe has already happened, but we only reach certain parts of it..

The idea that time is like an arrow that moves forward and never returns. It arises from irreversible processes observed in nature. For example, when a glass falls to the ground, it breaks and cannot return to its original state; or after breaking and frying the egg, there is no possibility of it returning to its original state. But in physics, the processes appear to be reversible.
