How could dark matter play a role in the future of the universe?

Scientists believe that dark matter may account for the unexplained motions of stars within galaxies. Computers play an important role in the search for dark matter data. They allow scientists to create models which predict galaxy behavior. Satellites are also being used to gather dark matter data.

Can dark matter be transformed?

Even if we assume that the “dark matter” is made entirely of “anti-matter”, then, it will annihilate and produce photons when it comes in contact with matter. So, there is no way of saying (as of yet) whether it is possible for dark matter to be converted into normal matter.

Are we entering a paradigm shift for dark matter?

While the LCDM framework has been incredibly successful for modern cosmology, it requires the admission of two mysterious substances as a part of the paradigm, dark energy and dark matter….Are We Entering a Paradigm Shift for Dark Matter?

Can we produce energy from dark matter?

When an annihilation occurs, they’ll produce pure energy in a 100\% efficient fashion: via Einstein’s E = mc2. In other words, if we understand dark matter correctly, there’s a free, unlimited source of energy everywhere humanity dreams of going. The XENON experiment located underground in the Italian LNGS laboratory.

Which discovery helped prove the existence of dark matter?

Astronomer Vera Rubin changed the way we think of the universe by showing that galaxies are mostly dark matter. On a dry and clear night at the Kitt Peak Observatory in the mountains of southern Arizona, Rubin closely observed the spectra of stars in the Andromeda Galaxy to determine their velocities.

What is Vera Rubin famous for?

Vera Florence Cooper Rubin (/ˈruːbɪn/; July 23, 1928 – December 25, 2016) was an American astronomer who pioneered work on galaxy rotation rates. She uncovered the discrepancy between the predicted and observed angular motion of galaxies by studying galactic rotation curves.

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 makes dark matter so hard to see?

Dark matter. Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot.

How does dark energy affect the expansion of the universe?

The even distribution means that dark energy does not have any local gravitational effects, but rather a global effect on the universe as a whole. This leads to a repulsive force, which tends to accelerate the expansion of the universe. The rate of expansion and its acceleration can be measured by observations based on the Hubble law.
