Most distant galaxies show a RED SHIFT. This is considered EVIDENCE that the universe is ___.

• getting cooler

• expanding

• condensing into a small point

• swirling around

The universe is expanding!  This means that:

• all of the galaxies are spreading out.
• the universe must have started from a single point.
• the universe is cooling down.
• all of the choices here.

Hubble's Law describes that the galaxies that are the farthest away from us are...

• moving away the fastest.

• moving toward us the fastest.

• not moving at all.

• disappearing.
