What statement is true about the concept of space-time?

• Two objects can exist in more than one space at the same time

• Time moves faster as you travel through space at very high rates of speed

• e=mc^2 breaks space and time

• Space and time are the same thing

What is cosmic background radiation?

• the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source

• beams of radiation that sweep through Earth's line of sight from spinning pulsars

• electromagnetic radiation leftover from the Big Bang

• the electromagnetic spectrum with wavelength from 10 nm to 400 nm and is present in sunlight

What is redshift?

• The phenomena whereby distant light in the Universe is shifted away from the red side of the visible spectrum.

• The phenomena whereby distant light in the Universe is shifted toward the red side of the visible spectrum.

• The phenomena whereby nearby light from the Sun is shifted away from the red side of the visible spectrum.

• The phenomena whereby distant light blocks red light from the visible spectrum.

Why is redshift significant to astronomers and cosmologists?

• Redshift provides strong evidence that the Universe is contracting.

• Redshift provides strong evidence that the Universe is neither expanding nor contracting

• Redshift provides strong evidence that the Universe is expanding.
