The Big Bang Theory & Evidence

The diagrams below represent spectral lines of hydrogen gas observed in a laboratory and the spectral lines of hydrogen gas observed in the light from a distant star. Compared to the spectral lines observed in the laboratory, the spectral lines observed in the light from the distant star have shifted toward the

• red end of the spectrum, indicating the star's movement toward Earth

• red end of the spectrum, indicating the star's movement away from Earth

• blue end of the spectrum, indicating the star's movement toward Earth

• blue end of the spectrum, indicating the star's movement away from Earth

As observed from Earth, the wavelengths of light from the most distant galaxies are usually

• blue shifted due to an expanding universe

• blue shifted due to a contracting universe

• red shifted due to an expanding universe

• red shifted due to a contracting universe

The red shift in light from stars located in very distant galaxies suggests that these stars are

• decreasing in temperature

• increasing in temperature

• moving toward the Milky Way

• moving away from the Milky Way

A major piece of evidence supporting the Big Bang theory is the observation that wavelengths of light from stars in distant galaxies show a

• redshift, appearing to be shorter

• redshift, appearing to be longer

• blueshift, appearing to be shorter

• blueshift, appearing to be longer

The Milky Way can best be described as

• an elliptical galaxy

• a collection of stars orbiting the Sun

• a star that originated 4600 million years ago

• one of billions of galaxies in the universe

• origin of the Sun

• radioactive decay in Earth's core

• formation of the Milky Way Galaxy

The presence of cosmic background radiation is evidence that helps support the

• Plate Tectonic theory

• process of global warming

• process of radioactive decay

According to the big bang theory, the universe began as an explosion and is still expanding. This theory is supported by observations that the stellar spectra of distant galaxies show a

• concentration in the yellow portion of the spectrum

• concentration in the green portion of the spectrum

• shift toward the blue end of the spectrum

• shift toward the red end of the spectrum

The diagram below represents the light spectra given off by the same element as observed under two different conditions. Spectrum A was observed when that element was heated in a laboratory. Spectrum B shows the same element as seen in the light from a distant star. The light spectrum observed from this distant star shows a

• A) red shift, which indicates that the star is moving away from Earth

• B) red shift, which indicates that the star is moving toward Earth

• C) blue shift, which indicates that the star is moving away from Earth

• D) blue shift, which indicates that the star is moving toward Earth

According to Hubble's Law, more rapidly moving galaxies are now

• A) further away from us

• B) closer to us

• C) accelerating rapidly

• D) already contracting toward another big bang
