Big Bang Notes

Multiple Choice

Predict: Which description is considered most accurate regarding what actually happened during the Big Bang?

• Two galaxies collided causing an immense explosion as stars crashed into one another

• All of what would become the universe was concentrated in a single small point, or singularity, which rapidly expanded into what is now stars, planets, galaxies, matter, and energy.

• All matter emerged from a massive black hole at the center of the universe.

Write in the highlighted information on Proof section

Multiple Choice

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

Blue shifiting

Wavelenghts or frequency is shorter indication objects are moving towards the earth

Multiple Choice
