Free universe but no free energy?

If the universe can bang itself into existence, then how come we can't bang ourselves some energy or matter?

Modern cosmology is so retarded that it shouldn't really be taken seriously. Modern cosmologists can't reconcile quantum mechanics with gravity, they can't explain the structure of galaxies without making up some imaginary "dark matter", they can't explain the increasing speed of Universe expansion without making up some imaginary "dark energy". In fact, according to modern cosmology, over 80% of energy in the Universe is "dark", i.e. they can't perceive it. Is it any wonder then that they can't explain shit?
