Page 7 - a past in the future

“The story goes that one day, a famous journalist of
the time asked him to explain his Theory of Relativity in a

way that was understandable to him. Albert Einstein was
unmoved and without losing his composure made another

request: Could you first explain to me how an egg is fried?
The very surprised journalist replied that, yes. And that’s

when Einstein said to him: Go ahead and do it, but explain

it to me imagining that I don’t know what an egg is, nor a
frying pan, nor oil, nor even fire.”

“Good answer, Dad,” Evelyn agreed. “I understand

that the journalist had, more or less, the same problem as

me.”

“That’s right,” David confirmed.

“Now for the second question.”

“I’m ready,” David agreed looking into Jennifer’s eyes

and then smiling at Martha and Glenn before turning his
attention back to his daughter.

“Why is it always claimed that space-time is curved?”

Evelyn asked.

“Not just the space-time, but space itself. What usually

happens to us is that we are not used to thinking in large
magnitudes and we always tend to focus our attention on

small spaces that we can dominate. I’ll give you an example

that you will quickly understand.”
