10m at Cas's ground is EXACTLY the same as 10m at Wigan's ground.

I'm sure nobody will swallow this but here goes
It's not though, as Wigan is further south than Cas so rotates slightly faster with the spin of the globe. This means time passes slightly slower in Cas than in Wigan and due to relativistic effects distances in Wigan are slightly compressed so 10 metres in Cas is actually further

Explains how Cas have the space to chuck it about more at home.

Time appears to tick slower and distances appear compressed as speed increases, but only (relatively) to someone watching from somewhere else. TBH though it would appear that both those places are moving faster than most since whenever you visit either it would seem that time has not moved on for quite a while......

Distance is a scalar measure and is a constant. It does not change relative to velocity.

Time is relative though. In Castleford, it's still only 1975.

Can you please add a punchline that is as funny as dboys?

A six-year-old boy spotted Albert Einstein walking down the street and decided to try out his favourite joke on him. "Mr Einstein! Why did the chicken cross the road?"

To which the famous physicist replied, "My young burgeoning mind, zee question does not have a definite anzer. Vether zee chicken crossed zee road or zee road crossed zee chicken depends on your frame of reference."

We do not understand time - it's a theoretical construct. Distance we do

As Professor Brian Cox points out - "The distance between the two points is the same - it’s given by what’s known as the metric, which describes the Earth’s surface. The travel time is usually shorter West-East...a consequence of the rotation of the Earth".

10 metres is 10 metres, wherever you are!

A point on the Equator "travels faster", than a point in the UK, in the sense that it has gone "further", in the same amount of time...but it's all, as they say, "relative".

So if your pitch is laid North South does it take less time to pass the ball to one wing than it does the other? Obviously this will then need adjusting in the second half.

This is some outstanding thread drift.
