Dark energy is one of the unsolved topic that scientist have no answers yet. We only can pretend that there is something like Dark energy. 74% of this Universe consists of Dark energy [22% of Dark Matter and rest our known masses as stars, intergalactic gases]. Dark energy was created the same time when the Universe born.
It is known that our Universe is expanding from the very start of Big Bang. So scientists think that it is that Dark energy that is helping the Universe to expand [Known from the red shift]; exactly opposite that Dark Matter do- Holds the galaxies to its shapes and prevent the expansion of Universe.
Other Opinion: From an alternate perspective, dark energy is thought to be the original medium of a pre-Big
Bang universe. Consequently the Big Bang creation event, via an unfolding of its condition from singularity, introduce the intrusion of our existence: a reality of positive density matter within a traditional fourth dimensional SpaceTime
continuum. Considering a pre-Big
Bang universe as zero density matter, the intrusion of positive density matter simultaneously provided for introduction of negative density matter (or dark matter). The resulting effect of bringing the universe back into the more ordered condition consistent with its pre-Big
Bang persistence is the expanding of the positive
density matter within our
fourth dimensional universe.
What else can I help you with?
What percent of the universe is made up of dark energy?
Dark energy -- whatever it turns out to be -- constitutes about 74% of the energy in our Universe.
Does dark matter/energy responsible for the expansion of the universe?
Yes. Dark energy is responsible for the expansion of the universe.
Is the universe matter?
The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.
Which is thought to be more prevalent in the universe dark matter or dark energy?
Dark energy. The current estimates for the distribution of mass/energy in the Universe are approximately: 68% dark energy 27% dark matter 5% baryonic (i.e. "normal") matter
Is dark energy and dark matter killing the universe?
No. What is killing the Universe is the Second Law of Thermodynamics.
What does dark energy seem to be doing?
Dark energy is the force that is driving the expansion of the universe
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.
What is the same about dark energy and dark matter?
there are the energy that mostly makes up this universe and its had been here since the beginning of the universe and also they are invisible.
What is the difference between negative energy and dark energy, and how do they impact the universe's dynamics?
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.
Which model of the universe requires the concept of the dark energy?
The one where the universe is expanding and accelerating.
What accounts for most of the mass in the universe?
Current theory states that it's "dark energy".
How is the energy distributed in the universe?
The energy in the universe is primarily distributed across three main components: dark energy, dark matter, and ordinary matter. Dark energy, which comprises about 68% of the universe's total energy content, is thought to drive the accelerated expansion of the universe. Dark matter accounts for about 27% and plays a crucial role in the structure formation of galaxies and galaxy clusters. Ordinary matter, including stars, planets, and interstellar gas, makes up only about 5% of the total energy density, highlighting the dominance of dark components in cosmic energy distribution.
