Sriram,
But you implied that, just as there are phenomena that weren't known before and are known now, so the various phenomena in which you choose to believe as conjectures must be "out there" too, only science hasn't got around yet to validating them.
That's not how it works though - when someone posits a conjecture that appears to have explanatory power (the Higgs-Boson for example) then the tools of science are used to find it. When they do, the conjecture becomes a fact and when there are enough facts that hang together to create an explanatory model they become a theory. Simply claiming a "biosphere" that those scamps in the lab coats just haven't had time to get around to finding yet is poor thinking.
Blue,
Its not that something 'must be out there '. The 'must' is wrong and the 'out there' is wrong too.
You assume that its a belief... like believing in Noah's Ark or Adam and Eve. And that based entirely on blind faith in some ancient legend, such phenomena are being imagined as fact. This is not true. Secondly its not about anything supernatural or 'out there'. Its about something 'right here' and very very natural.
Many experiences in our lives such as Synchronicity, ESP, sudden cures etc...and even simple observations such as the interconnected ecological system, emergent properties of organisms.... which defy explanations......make the existence of a common biofield imperative.
As I keep repeating...its nothing supernatural 'out there'. Its like the earths magnetic field which we can't feel or sense in any way but which none the less exists as an important part of our lives.
I have no idea what this interconnecting biofield is or what it is made of ....but that it exists can be deduced through many indirect experiences.
Now the question of why such a common bioield cannot be seen or sensed. The simple answer is that many things that even science proposes cannot be sensed or identified directly.....such as Dark Matter, Dark Energy and so on. And these are said to exist all around us too. Mere mathematics cannot be the reason for accepting something as true or as 'proved'....and the absence of mathematical formulations cannot be taken as proof of the nonexistence of something.
So....the fact that the biofield cannot be sensed directly cannot be a reason for its outright dismissal. There are enough reasons to accept it as a valid hypothesis. Its just that such phenomena have traditionally been associated with religion and God which make them a strict 'No..No'... in scientific circles. This is obviously wrong and is a major impediment to gaining knowledge of our world.
