This is also interesting - if for no other reason than it's an explanation by Professor Moriarty!

There are three fundamental questions for anyone advocating Brexit:

1. What, precisely, are the significant and tangible benefits of leaving the EU?
2. What damage to the UK and its citizens is an acceptable price to pay for those benefits?
3. Which ruling of the ECJ is most persuasive of the need to leave its jurisdiction?

Good them, thanks Alan.

First one gave me a clue to something I thought of some time ago whilst trying ti find a way of explaining relativity.

A kid on a train drops a marble, to him the marble falls vertically - let's say for two feet. To the external, stationary, observer that marble falls in a much longer curve (it is accelerating @ 32 ft/sec/sec which made things less easy). I did not have the math to work out how long that curve was or why the fact that it was a curve was important - I just knew it was.

Now I at least know that the acceleration makes it different from a pulse of light! Hmm . . . .

A belated but very warm welcome to the forum Minecraft.

Good name by the way. My son and I have spent a bit of time 'Minecrafting' together.

Kindest regards,
