Dark matter does not interact directly with radiation, but it does affect the CMB by its gravitational potential (mainly on large scales), and by its effects on the density and velocity of ordinary matter.

However, such theories cannot explain the observed … Terms in this set (9) Which does not provide evidence for dark matter? The indirect evidence all shows that it's real. In our solar system. Jim_Weiser. These observations provide the strongest evidence yet that most of the matter in the universe is dark. Match. Dark Matter May Feel a “Dark Force” That the Rest of the Universe Does Not. A: the planets in outer orbits move at a slower speed than those in inner orbits. Test. STUDY.

Astro 1 Unit 4 Part 9. Ordinary and dark matter perturbations, therefore, evolve differently with time and leave different imprints on the cosmic microwave background (CMB). Despite considerable evidence for dark matter, some scientists have proposed alternative theories for gravity where it is stronger on intergalactic scales than predicted by Newton and Einstein, removing the need for dark matter. Write. B: The light that dark matter radiates.

68.3% - dark energy; Therefore, dark matter makes up almost 85% of the total matter in the universe. Not finding dark matter in an experiment is not evidence that dark matter doesn't exist.

Created by.

Gravity. These five independent pieces of evidence, when taken all together, provide a compelling reason that dark matter must exist. Learn.

Flashcards. However, physicists currently don't understand what dark energy or dark matter is.

Which does not provide evidence for dark matter A The large rotational from ASTRO 001 at Pennsylvania State University PLAY. Spell. A new study makes the bold claim that dark matter might not need to exist to explain strange observations in the universe; but scientists aren't convinced that the study holds water.
