how is dark energy related to the theory of the multiverse?

In the 1980s, astronomers turned to multiverse theory to explain the “luckily small” amount of dark energy in our universe. According to cosmologist's theories, this small amount of dark energy appeared to enable our universe to host life, while most universes in the multiverse couldn't.

In special relativity In fact, negative kinetic energy exists in some models to describe dark energy (phantom energy) whose pressure is negative. In this way, the negative mass of exotic matter is now associated with negative momentum, negative pressure, negative kinetic energy and faster-than-light phenomena.

In 1927, the Belgian Catholic priest Georges Lemaître proposed an expanding model for the universe to explain the observed redshifts of spiral nebulae, and calculated the Hubble law. He based his theory on the work of Einstein and De Sitter, and independently derived Friedmann's equations for an expanding universe.

A Physicist Has Calculated That Life Really Could Exist in a 2D Universe. Our entire living reality happens in a three-dimensional Universe, so naturally it's hard to imagine a universe with just two dimensions. But, according to new calculations, a 2D universe could actually support life, too.

The physical universe is defined as all of space and time (collectively referred to as spacetime) and their contents. Such contents comprise all of energy in its various forms, including electromagnetic radiation and matter, and therefore planets, moons, stars, galaxies, and the contents of intergalactic space.

Dark energy is believed to be responsible for the expansion of the universe, counteracting gravity, and is considered to be the fifth force acting on matter, after gravity, the electromagnetic force, and the strong and weak nuclear forces.

Assuming the dark energy is constant (a cosmological constant), the current distance to this cosmological event horizon is about 16 billion light years, meaning that a signal from an event happening at present would eventually be able to reach us in the future if the event were less than 16 billion light years away, ...

Dark energy has currently only been detected through its gravitational effects. The universe is expanding, but gravity acts to slow down the expansion -- at least gravity for normal matter. ... Dark energy has currently only been detected through its gravitational effects.

The universe is neither open system, closed system, nor isolated system. It is just an infinite system that has no surroundings, no environment to be closed, isolated or opened to.

The closed universe, which is a universe where space-time is curved back on itself, one that has a finite size but no center and no edge. The open universe, which is a model of an infinite universe involving curved space-time, which does not curve back on itself.

Which statements are true regarding the cosmological principle? T- The universe looks the same from all directions, but can change and evolve over time. The universe looks the same from all directions, and hasn't and won't change or evolve over time.

Dark energy is the name given to an almost-entirely unknown force causing the Universe to expand at an ever-accelerating rate. Some describe dark energy as a “fifth” force acting on matter. The is beyond the four already known: gravitational, electromagnetic, and the strong and weak nuclear forces.

Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called "parallel universes," "other universes," "alternate universes," or "many worlds."

Yes. Everything in the universe consists of energy. So when we talk about everything tangible and even intangible, it's made up of energy. Now the inanimate objects are vibrating on different levels than we are.

['How has the universe come into existence?', 'Who or what caused the existence of the universe?', 'Will the universe cease to exist? How?', 'Is the universe infinite?', "What's inside a black hole?", 'Why do we exist?', 'Why is there life?', 'Is there alien life?']

While dark energy is a force that accounts for the expanding universe, dark matter explains how groups of objects function together. In the 1950s, scientists studying other galaxies expected gravity to cause the centers to rotate faster than the outer edges, based on the distribution of the objects inside of them.
