    • ‘I patented nanotechnology, antigravity devices, and genetic techniques of all sorts by my teenage years.’
    • ‘They took their oxygen suits off and walked over to their antigravity beds.’
    • ‘So this mysterious stuff has been labelled ‘dark energy’ and is a kind of cosmic antigravity force that counteracts the attractive force of gravity.’
