After the shock of Albert Einstein physicists have been considerably less rigid about what is going on in the material world. It sometimes seems that the weirder the theory the more interesting it is to at least some scientists. Newtonian world was so neat and predictable! Today there is uncertainty even about Heisenberg's uncertainty.
Researchers do not find it overly difficult to calculate stranges and tops and colors nor the theory of 11 dimensions or multicosmos.
In contrast, there is great difficulty in dealing with multiple layers of reality and the possibility of different spheres of life itself.
Spiritual reality is beyond mathematics and experimental science and this is taken by some as proof that there is no spiritual reality.
I find this rigid materialism somehow surprising in light of the obvious fact that human beings are spiritual beings and differ in this from all other creatures upon Earth as far as we know. Or have you heard dolphin discussing global warming?
So why such dogmatism about something we have hardly even started to study scientifically and know next to nothing about?
How come you can doubt and thus exist, as Descartes famously noted.
"Then the Lord God formed a man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being."
Genesis 2:7 NIV
