Thats a shortsightedness on their part.
I think they are focussing in the wrong area.
Paradoxically the verification requires Energy of level of Universal Birth.If you believe in Mathematical Calculations based on Bosons and Fermions you will not dare to risk the life of Universe by creating such scenario.Short Bursts of Energy can be created but it is difficult to contain such a Energy for Long time to observe.
And there are complete unknown effects related to such states when high in number.
Undoubetedly our means of measurements are ancient and our means of communications are ancient when compared to Animal Worlds ability.
Therefore is lot of scope for improvement.
I think everyone should be confident of finding the Truth themselves someday.Infact there is no censorship at all.We are living those laws everyday .. it is just that it no more remains demonstratable with current technology.
Probably we all are waiting for that new technological breakthrough before finding the right answer.From where it will come is a good debate we should undertake with confidence...
