I have an idea how to create a mechanical device that does what a worm hole does.The machine consists of 3 rows of four rectangular objects with a u shape piece tank tread on it.For the first row the top rectangular object underneath a u shaped piece of tank tread that is going 58 mph. goes 10 miles per hour backwards on the second rectangular object.The second rectangular object underneath the first one goes 10 miles per hour backwards on the third rectangular object.The third rectangular object underneath the second rectangular object goes 19 miles per hour backwards on the third rectangular object.The fourth rectangular object underneath the third one goes 10 miles per hour forwards.

For the first row the top rectangular object underneath a u shaped piece of tank tread that is going 58 mph. goes 10 miles per hour backwards on the second rectangular object.The second rectangular object underneath the first one goes 10 miles per hour backwards on the third rectangular object.The third rectangular object underneath the second rectangular object goes 10 miles per hour backwards on the third rectangular object.The fourth rectangular object underneath the third one goes 1 miles per hour forwards.

For the first row the top rectangular object underneath a u shaped piece of tank tread that is going 58 mph. goes 10 miles per hour backwards on the second rectangular object.The second rectangular object underneath the first one goes 10 miles per hour backwards on the third rectangular object.The third rectangular object underneath the second rectangular object goes 11 miles per hour backwards on the third rectangular object.The fourth rectangular object underneath the third one goes 2 miles per hour forwards.

I found that going backwards on a object going forwards slows things down.So i then subtracted the least speed from the greatest speed of either forward or backwards rectangular ojects to get the speed of either side of the u shaped piece of tank tread.
