问题     One theory about the universe says that it has no boundary, no edge.
This theory was proposed by Stephen Hawking and Jim Hartle. It says 【M1】______
that the universe has a finite area, but no one travelling through the
universe would ever come to a point that the universe stops. This 【M2】______
would be similar to journey over the surface of Earth. We can travel 【M3】______
around the world without reaching boundaries nor edges, yet the area of 【M4】______
the planet is finite. This no boundary theory predicts what the universe 【M5】______
does have a beginning and an end, but it differs off the traditional 【M6】______
Big Bang theory in some ways. The traditional Big Bang theory
assuming that the beginning of the universe was a singularity, a point 【M7】______
of infinite density and infinitesimal volume to where space and time 【M8】______
became distorted. Instead, Hawking and Hatle predict
that the beginning of the universe could likened to the North 【M9】______
Pole of the Earth. If degrees of latitude on the Earth could be
compare to time, it could be said that the universe began 【M10】______
at the North Pole. However, the North Pole in itself is just an ordinary
point on Earth.
