Could white holes actually exist? (www.space.com)

White holes are mathematically possible, according to general relativity. But does that mean they're actually out there?

According to my understanding, beyond the event horizon, gravity is infinite.

I am not a physicist - I'm a guy who read Prof. Hawking. Given the nature of llight vis a vis observation, inside the singularity, mass and gravity approach infinity.

Mass bends spacetime into gravity. Gravity bends light. Infinite mass > infinite gravity > stops light == singularity.

Note that things happening near the singularity are not the same as things that happen beyond the event horizon.
