Answer 2

$\huge\sf\underline\purple{Dark energy}$

Dark energy is the name given to the mysterious force that's causing the rate of expansion of our universe to accelerate over time, rather than to slow down. That's contrary to what one might expect from a universe that began in a Big Bang. Astronomers in the 20th century learned the universe is expanding.

$\huge\sf\underline\purple{Dark matter}$

Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly. ... Scientists believe that dark matter may account for the unexplained motions of stars within galaxies.
