@FBM,
If what you have said before about those scientists is true...Then there is 2 options with one alternative...and it can be no other way...
Option number 1, they are attempting to validate that there is no 4th dimension, and either will or will not...
Option number 2, what we think is the 4th dimension is an actual characteristic of the 3rd dimension and is not its own dimension...
One alternative out...They use this scope or anything else to look into the future since it is forever going, and prove and validate what the future holds with facts, that are not previously known...and these predictions always come true...
Yes, I know that there is time, but it is possible that man created this 4th dimension within the confines of the 3rd dimension itself, and it is real to us since it applies to the 3rd in which we live in...but it isn't real...
Or the only way to the 4th dimension is through a God that they refuse to try to validate by looking into the past, instead of the future...and either know this and do not want to look...or do not know this...and think they are looking...Or do not know this...and do not want to look...and are not looking...though they may "think" they are...
