In 1998, scientists discovered that the expansion of the universe has been accelerating.
KengaRu [80]

Answer:

Option A (dark energy) is the right answer.

Explanation:

  • A hypothetical supplier of power that creates a force that contradicts gravity, which is assumed to have been the catalyst of accelerated universe development.
  • Hypothetically, dark energy counteracts the kinetic energy including its beginning of the globe, meaning that perhaps the multiverse does not have intrinsic curvature, although observational measurements presently indicate.

Some other three choices have no relation to the particular situation. Thus option A would be the right solution.
