Why Is It Not Possible to Look All the Way $\gt$

question 19

Multiple Choice

Why is it not possible to look all the way back to the Big Bang itself?

• A) Photons are not produced until the stars begin to shine at a redshift of z = 20.
• B) From redshifts of z =0 to 100, photons are gravitationally lensed by the dark matter in the universe.
• C) At redshifts of z \(\gt\) 1,000, most of the photons are blocked by large amounts of cold gas and dust.
• D) For redshifts of z \(\gt\) 1,000, photons are heavily altered because they easily react with individual protons and electrons in the universe.
• E) Photons from the Big Bang would be so strongly redshifted that we could never detect them.
