As science improves, an enormous amount of knowledge has been accumulated about our universe and how everything around us works. We think about ourselves as the most intelligent species in the universe and the most capable in the entire universe.

96 percent of all content in the universe is dark energy. This component is the largest of our universe, and presently, the most mysterious. Thousands of researchers from all over the world are working day and night to solve this great mystery of science. Dark Energy is a component of our universe that seems to guide and control how our universe creates and controls all structures in it, small and large.

Without Dark Energy, our universe would be dominated by gravity and crushed into a so-called “Big Crunch”, or simply it would collapse into itself. So far, we can’t really tell what dark energy really is but we know that we should be thankful that exists.

Here I give you some theories about what dark energy could be and how our universe will eventually die because of this dark force.

This theory is created from Einstein’s theory about gravitation, the discovery that even empty space can have its own energy. This is called the cosmological constant. Einstein also theorized that space itself could be created from nothing, and as space creates itself, and as more and more space come into existence, more and more energy can fill that newly created space within it.

We see that our universe is in the process of rapid expansion and this could explain that process. This process will continue until every single object in the universe is so far away from all other objects that all universe will end in total darkness and coldness.

Theory of Everything

Most astronomers think that the search for dark energy is in vain. Instead of that, they propose that is more important to find the “theory of everything”, and this theory (when discovered) will solve the problem of dark energy naturally.

The purpose of this theory is to explain how all objects in the universe behave from the biggest ones to the smallest ones. Presently, two dominating theories are divided into large theories such as quantum mechanics which explains our universe on small scales, and the theory of gravity which explains our universe on the largest scales.

Solving the problem of dark energy seems logically inevitable, but so far finding the answer has proven totally impossible even for the brightest scientists in physics. All common laws of physics seem to “break down” when we start to observe our world on the quantum level. But fortunately, the search will continue in the future.
