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.
