It's kind of one of those "Damned if you do, damned if you don't" situations. If you create a new thread somebody will complain that you created a new thread when there are already XXX number of threads about that topic. If you use Tapas suggestions and add to an existing thread somebody will complain that you've revived a dead thread.
One thing I've noticed, which doesn't seem to be the case but might help if it was, is that at the bottom of every thread it says "Thread will automatically be closed 30 days after the last reply". This doesn't seem to be the case, though, because old threads are always being revived. Sometimes, very old threads, like this one.
As for a Fun Fact (Sorry, I recently read Stephen Hawking's Brief History of Time and found it fascinating): People often express fear that mankind could destroy itself by creating a black hole on Earth with the Large Hadron Collider. This is a silly fear, because there is not enough matter in our solar system to create a black hole. Black holes are created by the collapse of a supermassive star - the gravity is so intense that the matter collapses in on itself and becomes super dense: Gravitational attraction becomes stronger than the atomic forces that keep individual atoms spaced apart. There is not enough matter in our solar system to create such a gravitational well. Even if you were to take the sun, all of the planets, all of the asteroids and dust in our solar system and mash in together there would only be a tiny fraction of the gravity required to create a black hole.
Now, theoretically, an extremely tiny black hole could be created by mashing atoms together, but this would take tremendous energy, more than we can muster, and the black hole that resulted would last a mere instant before coming apart again. And even if you somehow managed to turn the sun into a black hole, its gravitational pull would be no greater than it is now, because the gravitational energy of an object cannot exceed the total gravitational energy of the matter that went into making it. If our sun became a black hole Earth would become dark and cold, but it would not get sucked in. You'd have to get onto a space ship and fly to the black hole that used to be the sun. Eventually you'd get close enough that you'd get pulled in, but the same thing would happen with the normal sun.
A black hole created from the sun would be approximately 6km in diameter. This 6km wide black hole would have identical gravity to the 1,400,000km wide sun we have now. That means that until you got to within approximately 700,000km from the center of the black hole you'd feel the exact same gravitational effects as you would with the regular sun (which is to say you'd be really, really heavy). Once you cross that 700k barrier and continue to head toward the black hole gravity would increase, just as it would if you were to somehow bore into the sun. It wouldn't be until you were nearly touching it, at 3km from the center, however, that you would experience the "Event Horizon", where gravity is so strong that not even light can escape.
Once again, this total gravity of this black hole is no greater than that of the existing sun, but it is now concentrated into a volume that is millions of times smaller than the sun. It would not start sucking all the planets in - they would remain where they are now, and would continue their orbits as normal. They'd just get really, really cold.
