The current state of science is mostly full of materialist scientists that believe in physical things. No matter have much evidence there is supporting a spiritual reality that we all go to when our physical bodies cave in. The same old catch phrase keeps coming ''extraordinary claims require extraordinary evidence'' well that is a valid assertion there is a EMORMOUS amount of evidence supporting these claims. Now i realize there are crackpots and loons out there like a lot of mediums who do deceive people. However there are some mediums that have shown they really can communicate with our loved ones.
The fear among many scientists is if Psi phenomena is accepted into the scientific community then there will be a paradigm change from materialistic to a spiritual view of the universe and of life. There's a good website countering skeptics arguments

For Example David Deutsch Ph.D.
works at the Centre for Quantum Computation at the Clarendon Laboratory, Oxford University. In the autumn of 2001, he denounced a fellow quantum physicist, Brian Josephson, for suggesting that quantum physics might lead to an explanation of "processes still not understood within conventional science such as telepathy". Deutsch asserted: "It is utter rubbish. Telepathy simply does not exist.
It's funny because David Detsche asserts that there are lots and lots of parellel universes also he talks about time travel neither one has any evidence.
Another good example is Dr.Richard Wiseman trying to debunk psychic pet phenomena
