Dark energy is omnipresent, and its effect increases as the cosmos swells. Its presence assists light to gain energy from the leftover radiation. If it moves through large masses and it is responsible for cosmic microwaves. When gravity becomes weaker due to space expansion, dark energy will start to dominate. It has been said that dark energy is responsible for the expansion of the universe. On the other hand, dark matter is non-luminous particles of matter that exert gravitational influences on galaxies' visible matter or clusters of galaxies. It is dark, invisible, and it encompasses most of the cosmic matter. The gravity of dark matter that pulls the universe together and keeping it away from possible collapse. Dark matter is said to be undetectable.

Dark energy is a form of energy that is assumed to have some anti-gravitational properties. This hypothetical form of energy is believed to be everywhere in space. If dark energy travels through a big mass, it causes light to gain energy. According to researches, dark energy constitutes about 74% of the total mass of the universe. As long as space is expanding, the effect of dark energy will continue to increase. A lot of things have been used to describe dark energy, but most researchers still see it as the repulsive force that is causing the expansion of space. Dark matter is particles of matter that are not non-luminous. As a result, you can't detect it even with their radiation. Dark matter constitutes about 22% of the mass of the universe. However, scientists have been able to detect its presence through their gravitational effects. For instance, the presence of dark matter is detected by determining the force it exerts on galaxies and stars.

Dark matter is responsible for making sure that the expansion of the universe will get reduced. There are a lot of people who say that the universe keeps on expanding and is more likely to get bigger. Without dark matter, there is a big possibility that it will be very big. Dark energy, on the other hand, is the exact opposite of dark matter. It makes sure that some parts of the universe will keep on expanding. Dark matter will have the ability to interact with gravity but it will not have the ability to absorb light and also emit light. It will also not have the ability to reflect light no matter how much light is shone into it.
