You should have understood that I meant otherwise. Of course, if we could notice the effect of EM, that could trigger an investigation eventually leading to the discovery.

>we know our sensory understanding has sever limits...

Did you really think I implied that no one knows the limits of our built in senses? When I said sensory capabilities I meant the stuff we can sense, directly or indirectly (By indirectly, I mean by the help of another device, to make it very clear).

Can you suggest an environment conducive to life that isn't exposed to EM radiation? Life itself creates EM radiation.

I can't prove God doesn't exist either, but that doesn't make it logical to conclude that we will one day be able to harness the power of God for FTL communications, but this is what you're expecting. If there are fundamental forces left to be discovered then they are not having any observable effect on the world, making them unlike all other fundamental forces. This makes them unlikely to ever be discovered.

There is nothing in the definition of "life" that warrants an ability to observe EM radiation or create it for that matter..By the way, what is the definition of "life" that you are using here?

>there are fundamental forces left to be discovered then they are not having any observable effect on the world..

So just because we haven't discovered something, does it mean that that thing is not observable at all? We are still discovering "things" in our own body, let alone in the entire world. The fallacy that human beings are capable of detecting every observable (by observable, I did not mean observable with our current tech) phenomena in this world is exactly what I was indicating before.

An incredible loose one. Basically any process remotely complicated enough to call life would be producing infra red radiation at least. From there the evolutionary pressure to be able to sense it is huge. Eyesight on our own planet could have evolved to see heat long before sunlight.
