Which is stronger dark matter or dark energy?

And what’s the difference between dark energy and dark matter? In short, dark matter slows down the expansion of the universe, while dark energy speeds it up. Dark energy is the far more dominant force of the two, accounting for roughly 68 percent of the universe’s total mass and energy.

Is there more dark matter or energy?

It turns out that roughly 68\% of the universe is dark energy. Dark matter makes up about 27\%. The rest – everything on Earth, everything ever observed with all of our instruments, all normal matter – adds up to less than 5\% of the universe.

Is there anything dangerous about dark matter?

There is nothing dangerous about dark matter or dark energy. Both are essential to the existence of the universe as we know it. The excerpt below from the manuscript “A Grand Unification Theory” deals with some of the major mysteries associated with studying the universe.

How much of the universe is dark matter and energy?

By fitting a theoretical model of the composition of the universe to the combined set of cosmological observations, scientists have come up with the composition that we described above, ~68\% dark energy, ~27\% dark matter, ~5\% normal matter. What is dark matter? We are much more certain what dark matter is not than we are what it is.

How do we know how much dark energy is there?

We know how much dark energy there is because we know how it affects the universe’s expansion. Other than that, it is a complete mystery. But it is an important mystery. It turns out that roughly 68\% of the universe is dark energy. Dark matter makes up about 27\%.

What is the difference between dark matter and ordinary matter?

Although both dark matter and ordinary matter are matter, they do not behave in the same way. In particular, in the early universe, ordinary matter was ionized and interacted strongly with radiation via Thomson scattering.
