Question
Which statement gives us the key Evidence that the Universe is Expanding?
a
Objects in the Universe are physically getting smaller, meaning they must be travelling farther away from each other

The Universe is getting hotter, which can only happen if the Universe is expanding faster.

Almost all light in the Universe is Blue-shifting, meaning those objects creating that light are moving away from each other.
d
Almost all light in the Universe is Red-shifting, meaning those objects creating that light are moving away from each other

The correct answer is:
d) Almost all light in the Universe is Red-shifting, meaning those objects creating that light are moving away from each other.
This redshift is a key piece of evidence supporting the expansion of the Universe, as it indicates that distant galaxies are moving away from us, and the farther away they are, the faster they are receding, which is consistent with the Big Bang theory and Hubble's Law.
