Comments on "Frontier experiments: Tough science- Five experiments as hard as finding the Higgs"

The five frontier experiments published in Nature are commented item by item: spotting distant signs of life, seeing through the molecular mirror, looking for extra dimensions, catching a gravity wave, redefining the kilogram. It is concluded that the first two experiments are great ideals that are impossible to realize in recent years, the last three are false theories pulling physics into morass. Key words: Nature, distant signs of life, molecular mirror, extra dimensions, gravity wave, kilogram.
