That means that the Universe expands faster and faster. It causes the Universe to grow, and the general density of matter in the Universe to decrease over time.

The mysterious force that may be causing the expansion of the universe to accelerate is called?
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.
What is the majority of the energy in our universe?
Something called "dark energy" which provides almost 70% of the total energy in the observable universe and is causing the expansion of the universe to accelerate (instead of decelerate as expected in the basic big bang model of the universe).
What fraction of the mass for stopping expansion does the universe have if dark and visible matters are considered?
Depending on what source you use for reference, it seems somewhere between 68% and 75% of the universe is dark energy accelerating the expansion, and somewhere between 25% to 32% is matter (dark or visible) exerting gravitational force which would notionally be resisting that expansion. Note that dark energy itself has mass (per mass-energy equivalence) so one needs to be cautious if the subject in question is the overall mass of the universe or what fraction of the overall mass tends to oppose that expansion - which dark energy does not.
Dark energy is an unexplained force that is causing?
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.
Is the Big Rip theory true?
At the moment The Big Rip is still a hypothesis. It is all to do with the amount of dark energy in the Universe. Until this is confirmed, it is impossible to say whether it is true or not.The ultimate fate of the Universe is not entirely known. We know that the universe will continue expanding at an accelerating rate, but it is unknown what this will result in. It is very possible that the outward expansion will result in all particles flying apart from one another as the force of expansion will overcome the forces holding atoms together. However, that will depend on exactly what Dark Energy is. Dark Energy is responsible for the expansion of the universe, but this is just a placeholder name for what really causes it- the nature of dark energy is currently unknown.
What is a component of the universe that seems to be counteracting the effect of gravity and accelerating the expansion of the universe?
Dark energy.

Does dark matter/energy responsible for the expansion of the universe?
Yes. Dark energy is responsible for the expansion of the universe.
Which model of the universe requires the concept of the dark energy?
The one where the universe is expanding and accelerating.
When would the universe end?
The expansion of the Universe is accelerating; it seems it will continue expanding forever. In this case, there won't be any specific date for an "end of the Universe"; however, the amount of usable energy will decrease over time, and the time will come when there won't be enough usable energy to support life.
What force do scientists such as Saul Perlmutter believe is counteracting gravity and allowing the universe to accelerate the rate of its expansion?
Dark energy is the term to refer to the force that is causing an expansion of the universe to accelerate. It is estimated that the universe is 68.3 percent dark energy, 26.8 percent dark matter, and 4.9 percent ordinary matter.
Is dark energy possible?
It is possible, but so far it is only hypothetical.

What caused the creation of the universe?
According to modern science, energy created the universe in the Big Bang 13.7 billion years ago since energy cannot be created or destroyed. Energy existed before matter, space, and time. Energy is also causing the expansion and acceleration of the universe. We can say with certainty that energy is eternal and existed even before the universe and will outlast the universe.
Is space formed by dark energy?
We do not know. Certainly current THEORIES suggest that dark energy is causing the universe to expand at a faster and faster rate. Its existence is postulated to explain why we can observe that the universe is expanding at an accelerating rate. However, we do not know what dark enery is (if it exists).
