I heard that if you drill a small hole in the side of a lightbulb, and then fill it with gas, you can tape off the hole and put the bulb back in place. Once someone switches the light on ka-boom. Will this really work? I heard lightbulbs have special air inside to keep the tungsten buring, if not it will just mix with the oxygen and meltdown... so will that work? Has anyone ever tried it?

I mean is it the heaviest per whatever measurement, like real dense?

I'd think lighter because its expanded and well, it shouldnt be lighter... ? does a red high 1 ounce steel ball weigh the same when it's red hot ?

The total amount of mass that is observed in our Universe is much smaller than the total quantity of mass required to account for the total gravitational pull that is present. Therefore the existence of a mysterious unobservable kind of matter is postulated("Black matter"), Could it be that this "Black matter" is no more or less than all the matter that has been accumilated in the gravity traps called "Black holes"? Such matter is (almost) unobservable , but does still exert its gravitational pull. Of course this means that the quantity of matter present in Black holes must be vastly larger than assumed until now. But why not? Black holes being alone in empty space, with no more matter around them to suck in, would be practically unobservable. One can imagine that such "lone" Black holes could originate from the collapse into one point of complete Galaxies or even clusters of Galaxies.
Or alternatively:
Very large numbers of "small" Black holes that also are almost unobservable?

Someone mentioned it to me and I wondered what it is and where it is...or if they are winding me up!
