Nothing can escape from a black hole

Thank you, Pain, and the viewers for making this debate possible.

The proposition that my opponent will be defending and I will be refuting is this: "Unless it's a white hole or dark matter, nothing in the universe can escape a black hole."

Why would I ever accept to this debate then? The proposition seems to be merely a quote from a science textbook, and therefore is not really up for debate. However, it holds a glaring flaw: the conditional phrase "Unless it's a white hole or dark matter". This means that my opponent must defend the contention that white holes and dark matter both can escape a black hole. To defend this, however, will prove impossible, as black holes can (and do) swallow dark matter.

I. Dark matter cannot escape a black hole.

It is rare, only because of dark matter's naturally little interaction with ordinary matter, but dark matter (when at just the right distance and acceleration) will be sucked into a dark hole [1]. Astrophysicists at Cornel University visit the subject and agree that dark matter accumulates relatively little of a supermassive dark hole's fuel, but it does account for ~10 percent [2].

II. Dark energy can escape a black hole.

My opponent was so close to having a bulletproof proposition. However, he surely meant to write "dark energy" instead of "dark matter". Dark energy is a mysterious thing; it's what causes the universe to expand and is completely unaffected by gravity. Therefore, it is the only known thing in the universe capable of escaping a black hole [3].

In conclusion, I have not only shown that his conditional phrase "unless it's a white hole or dark matter" to be false (as dark matter, in fact, cannot escape a black hole), I have also shown the core thesis "nothing in the universe can escape a black hole" to be false (as dark energy can).

Seeing as how we are dealing with scientific fact, and these cannot be disputed, I see no reason to prolong this debate another four rounds. However, as I agreed to partake in them when I initially accepted the debate, I shall continue to falsify my opponent's proposition as needed for the duration of the debate. I look forward to my opponent's response and wish him luck.

My opponent has forfeited his round. Seeing as how there is nothing more for me to say, as I have already debunked the proposition, I will pass on this round as well.
