New Study Suggests That Dark Energy Is The Reason Time Moves Forward

The Second Law of Thermodynamics tells us that the disorder of a closed system like our universe must always increase, never decrease. Also known as ‘entropy’, it’s the reason that things do no reassemble or come back to life.

When objects like stars, our planet and humanity are created, they add energy to the universe. This in turn adds to the entropy/disorganization rate of the universe. The law of Entropy is dependent on the direction of time. If time were to move backward, the disorganization would reverse. So, in theory, whatever causes our universe to expand is directly linked to the direction of time. What causes our universe to expand?

Well, we don’t really know what it is exactly…but we call it ‘dark matter’. Without dark matter and according to what we understand about gravity, the universe would collapse. The continuous expanse of our universe, and the reason is doesn’t collapse on itself is all due to this mysterious and unknown energy.

Now, two Armenian physicists have set out to search for this link between ‘dark matter’ and the law of Entropy. What they did was create a simulation of the orbit of a planet. They then would test how the orbit changed depending upon whether dark energy was absent, or present.

What the scientists discovered is rather incredible. They found that with the effects of dark energy absent (gravity being allowed to pull space together) a planet simply orbits its star in the normal way, regardless of the direction of time. But when dark energy is introduced to expand space, the planet is eventually flung away from the star it’s orbiting compeltely.

“This means there is a temporal directionality when dark energy is introduced—in one direction, we see a planet escaping a star’s gravity; in the other, a planet is captured by a star and becomes a part of its retinue.” – Futurism

While the study isn’t completely conclusive it’s still a very interesting demonstration that brings to light a lot of questions. If the Second Law of Thermodynamics and dark energy are facets of the same phenomenon, then we are just that much closer to understanding one of life’s greatest mysteries. Time.
