"Not any more invisible than the air you breath or the internet."
No Mr. Bill. Dark energy and dark matter are invisible by definition. Air is a gas and gas is visible. Your 'internet' crack, oh well. Lack of real evidence leaves only mind-spasms.
"No, it's an application of Occam's Razor and a expressive recognition of the relationship between mass and energy. Got E=mc^2?
No Mr. Bill. Dark energy and dark matter supposedly do not interact w/ normal matter and energy except as a gravitational effect.
"Do you likewise deny the potential energy in the wind - because it's "invisible"... to you?"
Wind is air is gas is visible. Dark energy and dark matter are invisible by definition.

>>Wind is air is gas is visible.
Didn’t ask about the gas. I asked about the energy conveyed therein.
Does your inability to see that energy render it non-existent? No, it does not.
Reality is that which exists regardless of whether you can see it, or not.
