Are Five Senses Enough?

The furor over the Higgs boson and the Higgs field make me wonder if there is a lot out there in the universe which we don't know about and don't understand because we can't easily perceive it with the five senses that we have.  Of those, the one sense we rely on most heavily for physics study is sight, perhaps assisted by touch.  Hearing, smell and taste don't contribute much to our understanding of the universe, although they are useful in our daily lives.  It took a long time to discover radio waves, although they are the same physical phenomenon as light, just at a different wavelength.  Similarly, everybody has experienced gravity all of their lives since the beginning of time, but only in the last few hundred years was it identified as a force that serves as the glue of the universe.  The odd behavior of matter in quantum mechanics might be less odd if we discovered some underlying force or principle that governs it.  Some quantum phenomena, such as entanglement, might promise instantaneous communication across the universe.  Why would advanced beings communicate by electromagnetic waves that can only travel at the speed of light if there is another means that is instantaneous.  These advanced beings could be communicating right now, but we would not know it, because we don't understand that medium of communication.  It may be far removed from the electromagnetic waves that we see or receive by radio.  We don't even understand gravity well, because it works through means other than those that we easily perceive with the five senses.
