Read the excerpt from A Black Hole Is Not a Hole by Carolyn Cinami DeCristofano, and answer the
question
According to the excerpt, what helped Einstein to draw
the conclusion that space was like a stretchy blanket
rather than rigid nothingness, as Newton believed?
In this way of thinking, the "background" acted more
like a flexible mat, or a stretchy knit blanket. This new,
blanket-like idea of space meant space could stretch,
crunch up, bend, and warp. Moving objects would
follow the curves of the blanket, moving along the
surface through flat sections as well as distorted ones.
This new idea about space changed the way scientists
think about gravity
Speaking of Gravity: Newtonese and Einsteinese
Most of the time gravity seems to work the way Newton
described it. Newton's rules explain a lot, from falling
apples to most planets' orbits. But his laws don't work
perfectly. In high-gravity zones, Newton's ideas don't
jibe with what scientists observe. For example,
O This new idea about space changed the way

Mercury's orbit-up close to the Sun—has a blip in it
that Newton's laws can't explain.
