Can Two Black Holes Collide?

A second-grader asks Neil deGrasse Tyson whether two black holes can collide and swallow one another. The answer includes backward time travel. Consider my mind blown.

  1. I thought this was about Al Sharpton and Jesse Jackson.

  2. The only object I can see near these 2 black holes in the TARDIS. What an episode that would be.

  3. Neil deGrasse Tyson has a great Podcast called StarTalk for anyone interested :)

  4. Nothing 12th grade about it.

    SOLVING it is way beyond 12th grade

    But asking it? That’s VERY 2nd grade.

    Anything odd or different is of interest to a 2nd grader.

    It takes a lot more public schooling to beat that kind of curiosity and inquisitiveness out of a child.

  5. Neil deGrasse Tyson is my hero and I listen to StarTalk Radio every Sunday night. He is one of the greatest minds of this century.
