Science itself does not ask for "belief" or "faith" or even "hope" -- none of such words have anything to do with strict scientific terminology.
Instead, we might recognize or acknowledge findings on some hypothesis as being a "confirmed" theory, pending future data or ideas which might yet falsify it.
When theories are strongly confirmed, we can use them in building machines & transportation equipment that our lives depend on, and in that sense we "believe" they work.
But in true science, it's always a temporary, conditional acceptance pending some future new data or ideas.
Unfortunately, the federal government is allowing their bureaucrats to enact regulations that treat these hypotheses and theories as facts set in stone.
Hence the reason for government grants.
