Answer 1

The response that best aligns with the trigger for the cyclic model of the universe is: Some scientists think that the universe will not keep expanding forever.

The cyclic model posits that the universe undergoes an infinite series of expansions and contractions, suggesting that it will eventually stop expanding and begin to contract again, leading to a new "big bang" phase. This perspective contrasts with the idea of a universe that expands indefinitely.
