A spinning star could collapse into a ring of
neutrons, which would remain stable because of the intense centrifugal force pushing outward, canceling the inward force of
gravity. The astonishing feature of such a black hole was that if you fell into the Kerr black hole you could not be crushed
to death. Instead, you would be sucked completely through the Einstein-Rosen bridge to a parallel universe. “Pass through
this magic ring and- presto!-you’re in a completely different universe where radius and mass are negative!” Kerr
exclaimed to a colleague, when he discovered this solution.
The frame of Alice’s looking glass, in other
words, was like the spinning ring of Kerr. But any trip through the Kerr ring would be a one-way trip. If you were to pass
through the event horizon surrounding the Kerr ring, the gravity would not be enough to crush you to death, but it would be
sufficient to prevent a return trip back through the event horizon.
In some sense, a Kerr black hole can be compared to an elevator inside a skyscraper. The elevator represents the Einstein-Rosen
bridge, which connects different floors, where each floor is a different universe. In fact, there are an infinite number of
floors in this skyscraper, each one different from the others. But the elevator can never go down. There is only an “up”
button, Once you leave a floor or universe, there would be no turning back because you have passed an event horizon.
Numerous universes might have been botched and bungled throughout
an eternity, ere this system was struck out; much labor lost, many fruitless trials made, and a slow but continual improvement
carried out during infinite ages in the art of world-making...
The new crew spacecraft will have more volume than the Apollo capsules, reducing development
time, boosting stability, and permitting safe travel for up to six crewmembers.
