Yes. Dark energy is responsible for the expansion of the universe.
What else can I help you with?
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 force do scientists such as Saul Perlmutter believe is counteracting gravity and allowing the universe to accelerate the rate of its expansion?
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.
What does dark energy seem to be doing?
Dark energy is the force that is driving the expansion of the universe
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.
What is dark energy in the universe?
The mysterious substance which is believed to accelerate the Universe's expansion. Look up "dark energy" on Wikipedia for more details.
Analysis all the models tell us that the universe should be slowing down but instead in speeding up how does this affect your model of the universe?
This discrepancy is known as the "accelerating expansion of the universe." In our model, we incorporate dark energy to explain this acceleration. Dark energy is a hypothetical form of energy that exerts a negative pressure, causing the expansion of the universe to accelerate. By including dark energy in our model, we can account for the observed accelerating expansion of the universe.
Does dark energy affect the size of a 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.
What two forces determine if a universe will expand or not expand?
The expansion or contraction of the universe is determined by the balance between the force of gravity (tending to pull matter together) and the force of expansion due to dark energy (driving matter apart). If dark energy dominates, the universe will expand; if gravity dominates, the universe will contract.
Is there enough dark matter to halt the the current cosmic expansion?
Not only is there not enough matter (dark or otherwise) to stop and reverse cosmic expansion, the rate of that expansion has been increasing over time. It would appear that dark energy is achieving "victory" over all matter.
Why is the expansion of the universe accelerating because of dark energy?
The expansion of the universe is accelerating because of dark energy, a mysterious force that counteracts gravity and pushes galaxies apart. This phenomenon was discovered through observations of distant supernovae and is believed to make up about 70 of the universe's total energy.
What is causing the acceleration of the universe's expansion?
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.
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.
