One of the Great Lessons Being Learned from Modern Astronomy

question 22

Multiple Choice

One of the great lessons being learned from modern astronomy is that:

• A) Earth occupies a unique position in the universe, and nowhere else are conditions equivalent to those in the solar system likely to be found.
• B) Earth's position and circumstances in the universe are quite ordinary and certainly not unique.
• C) the chemistry, geology, and physics on Earth are unique to our planet, and the behavior of matter anywhere else appears to be significantly different from that on Earth.
• D) Earth is at the center of a very massive black hole, and all the observed cosmological effects such as redshift and cosmic background radiation and even the evolution of life are a consequence of the unique position Earth occupies.
