Answers
Answer:
dark energy and matter is the 96℅ of universe. u might be unknown of the fact that the matter that we see is only 4℅ of the universe.
dark matter is responsible for the expansion of universe since the big bang theory.
in universe all the planets can't be held by gravitational field as they are far more weak, here dark energy plays an important role of fixing the planets and stars on the dark matter
Answer:
Hey mate here is your answer,
Dark matter:
The visible universe including Earth, the sun, other stars, and galaxies is made of protons, neutrons, and electrons bundled together into atoms.
The rest of the universe appears to be made of a mysterious, invisible substance called dark matter 25% and a force that repels gravity known as dark energy 70%. It's completely invisible to light and other forms of electromagnetic radiation, making dark matter impossible to detect with current instruments.
Dark energy:
Dark energy is even more mysterious, and its discovery in the 1990s was a complete shock to scientists. Previously, physicists had assumed that the attractive force of gravity would slow down the expansion of the universe over time. But when two independent teams tried to measure the rate of deceleration, they found that the expansion was actually speeding up. One scientist likened the finding to throwing a set of keys up in the air expecting them to fall back down-only to see them fly straight up toward the ceiling.
