Science has informed us officially, just in time for Christmas, that sometime in the next few hours or later the universe will collapse and everyone will die. That's the tabloid version. In hypothetical reality, everything in the universe will become heavier than it is now, as already evidenced in the tons of fad diets that are as everywhere as articles on cellulite, to say nothing of what we personally are actually seeing even now at our very waistlines.
To be more hypothetically specific, and to give you all a heads-up on this, everything in the universe will become billions and billions of times heavier than it is now (so there's really no point in letting out those pants) and everything will be compressed into superheavy and superhot balls (as presciently sung of by Jerry Lee Lewis, back in the fifties) that roll around heaven all day, and the universe will cease to exist-- at least in the form familiar to our world. Which, if you look at what we're doing to the place, may not turn out to be all that much of a change.
Those scientists' humongous guesses may be just as right as the next guy's, but the labcoat denizens seem to have no sense of propriety as to this actual moment in the time and space continuum.
