How is gravitational lensing related to dark matter?
ty !
The gravity of dark matter distorts the light from distant galaxies.
thanks mama!
Because dark matter's effects are detectable via gravity, we can "see" the presence of dark matter via its gravitational-lensing effects. In a few cases, we've even detected lensing where little matter is present. That's one of the many pieces of evidence in favor of dark matter.

1. Which correctly relate dark matter and darker energy to The Big bang theory?
-Through dark energy the universe is expanding at a faster and faster rate
-Because of dark matter gravitational interactions cause galaxies to develop
2. Redshift is observed when:
-A distant luminous object travels rapidly away from an observer
3. How is gravitational lensing related to dark matter?
-The gravity of dark matter distorts light from distant sources
4. Which statements about nuclear fission and nuclear fusion are true?
-They both released large amounts of energy
-They both occur in the nucleus of an atom
5. Which statement about nuclear fission is correct?
-Nuclear fish and takes place in the nucleus of atoms
6. What type of evidence does cosmic background radiation provide about the origins of the universe?
-It verifies that the early universe was once extremely hot
7. How does the proportion of hydrogen and helium in the universe support the Big bang theory?
-It is the proportion predicted to be present in the early universe
8. Drag and drop
The first piece of evidence (Edwin Hubble)...
-Galaxies are moving away from each other
The second piece of evidence (Universal Temperature)...
-Has decreased dramatically
The third piece of evidence (background radiation)...
-Uniformly across the universe
9. The Stars at the edges of a Galaxy are rotating around the Galaxy center at the same speed as the stars in the middle of the Galaxy. How does this provide evidence of dark matter?
-Dark matter provides the gravity that allows the Stars to rotate at the same speed
10. Drag and drop
Dark MATTER is the only explanation for the structures of the early universe. Clumps of it led to FORMATION OF GALAXIES in the early universe. Without it, the universe would have REMAINED UNIFORM.
Be careful, always double check.
grandiloquence is 100% correct
good luck future students
