Dark Energy is an unexplained theoritical mathematical quantity that is proposed to account for the apparent steady increase in the rate of expansion of the universe.
Dark energy is thought to be the dominant force driving the accelerated expansion of the universe. Therefore, it does affect the size of the universe by causing it to expand at an accelerating rate. This expansion is causing galaxies to move away from each other at increasing speeds.
The current state of affairs with regard to the expansion of the universe point to dark energy as the cause of the expansion of the universe. It is not a force though.
The expansion of the universe is causing galaxies to move away from each other, with space itself expanding between them. This expansion is driven by dark energy, a mysterious force that counteracts the gravitational pull of matter in the universe.
The force that can prevent the universe from expanding is gravitational attraction. If the density of matter in the universe is sufficiently high, gravity can overcome the expansion driven by dark energy and the initial conditions of the Big Bang. This gravitational pull could lead to a scenario known as the "Big Crunch," where the universe eventually collapses back into a singular point. However, current observations suggest that dark energy is dominating, causing the universe to continue expanding.
The observations made from distant galaxies suggest that Dark energy exists. This is because of the fact that the galaxies are moving away from each other. This is given by Hubbles law.Instead of being attracted by the force of gravitation,galaxies tends to move away suggesting the presence of a gravity opposing force called dark energy.

The acceleration of the universe's expansion is believed to be caused by a mysterious force called dark energy. This force is thought to counteract the gravitational pull of matter, causing the universe to expand at an increasing rate.
Dark energy is the force that is driving the expansion of the universe
Scientists like Saul Perlmutter believe that dark energy is the force responsible for counteracting gravity and driving the accelerated expansion of the universe. This mysterious form of energy has a repulsive effect and is thought to make up a large portion of the universe's energy density.
The current state of affairs with regard to the expansion of the universe point to dark energy as the cause of the expansion of the universe. It is not a force though.
Dark energy is important to earth in maintaining earth's orbit distance (centrifugal force, cDel.P) and the circulation force, cDelxP).
Negative energy and dark energy are two distinct concepts in physics. Negative energy refers to a theoretical concept where energy levels are below zero, which is not observed in nature. On the other hand, dark energy is a mysterious force that is thought to be responsible for the accelerating expansion of the universe. While negative energy is not directly observed, dark energy has a significant impact on the dynamics of the universe by counteracting the gravitational pull of matter and causing the universe to expand at an increasing rate.
The expansion of the universe is primarily driven by dark energy, a mysterious force that is causing the rate of expansion to accelerate. Gravity, the attractive force between objects with mass, also plays a role in shaping the large-scale structure of the universe.
The two are quite unrelated. It would be harder to find similarities than differences. More exactly, the two are only related by the fact that (as of 2013) we don't understand either -- thus the name "dark." Dark matter is the type of matter that exists throughout our Universe, which interacts with baryonic matter (ie, the stuff we understand) only through gravity. This stuff (whatever it happens to be) warps space and prevents galaxies from flying apart as they spin; but does not interact via the electromagnetic force, the strong force, or the weak force. Its mass density in our Universe, as best we can tell, is about six times greater than that of bayronic matter. Dark energy is whatever is causing the space within our Universe to increase the rate of expansion. Gravity SHOULD be slowing down that expansion over billions of years, but SOMETHING is causing the rate to go higher. What is causing this? -- we have no idea!!
The expansion of the universe is causing galaxies to move away from each other, with space itself expanding between them. This expansion is driven by dark energy, a mysterious force that counteracts the gravitational pull of matter in the universe.
Space is constantly expanding because of the force of dark energy, causing galaxies to move away from each other. There is no boundary or edge to the universe, so it appears to go on forever. Gravity from matter in the universe acts as a brake on this expansion, but dark energy seems to be winning, pushing the universe to expand at an accelerating rate.
The space itself is expanding due to the continuous stretching of the fabric of the universe, causing galaxies to move away from each other. This expansion is driven by dark energy, a mysterious force that counteracts gravity on a cosmic scale.
