However, in day-to-day experience, the strangeness of
Einstein's ideas doesn't help us, and Newton's notions
do just fine. In everyday life, when gravity isn't
especially intense, Newton's and Einstein's ways of
thinking lead to similar results. The two explanations
work like different languages that express the same
thing. Is an apple red (English) or rojo (Spanish)? It's
okay to use either description.
So we still use Newton's laws—even scientists do.
much of the time. Sure, it's more exact to be
Einsteinian and think of gravity as matter's effect on
space. But it's all right to take a Newtonian shortcut and
imagine gravity as a pull.

A. Sometimes scientific questions are left unanswered.
B. Some things can have more than one explanation.
C. Knowing two languages helps to understand
science
D. Choosing between two different ideas can be
difficult.
