To help you decide, here’s a classic pop science article by Anil Ananthaswamy of New Scientist, fronting the multiverse:
Today’s measurements show the universe to be flat, but the uncertainty inQuestion: For a free copy of Expelled, is this a way to do science? Note, you must register at Uncommon Descent to comment.
those measurements still leaves room for space-time to be slightly curved -
either like a saddle (negatively curved) or like a sphere (positively curved).
“If we originated from a tunnelling event from an ancestor vacuum, the bet would
be that the universe is negatively curved,” says Susskind. “If it turns out to
be positively curved, we’d be very confused. That would be a setback for these
ideas, no question about it.”
Until any such setback the smart money will remain with the multiverse
and string theory. “It has the best chance of anything we know to be right,”
Weinberg says of string theory. “There’s an old joke about a gambler playing a
game of poker,” he adds. “His friend says, ‘Don’t you know this game is crooked,
and you are bound to lose?’ The gambler says, ‘Yes, but what can I do, it’s the
only game in town.’ We don’t know if we are bound to lose, but even if we
suspect we may, it is the only game in town.”
