Time's Up ... Someday

A group of physicists from our local UC Berkeley has delivered a chilling bit of news: time itself has a 50% chance of coming to a halt. This conclusion is based on what they term the "measure problem" of an infinitely expanding universe. As the report states,
If the universe lasts forever, then any event that can happen, will happen, no matter how unlikely. In fact, this event will happen an infinite number of times.

This leads to a problem. When there are an infinite number of instances of every possible observation, it becomes impossible to determine the probabilities of any of these events occurring. And when that happens, the laws of physics simply don't apply. They just break down. ...

The only way out of this conundrum is to hypothesise some kind of catastrophe that brings an end to the universe. Then all the probabilities make sense again and the laws of physics regain their power.

Really, that's the argument. Douglas Adams is dead, so despite all appearances, it didn't come from him.

There is good news, though. Time is not expected to stop for another 3.7 billion years.

So go ahead and buy the green bananas.
