"To get anywhere, or even live a long time, a man has to guess, and guess right, over and over again, without enough data for a logical answer."
- Robert Heinlein

| Gravity Lens | ||
| An optical lens created using the lightbending properties of gravity. |
The classic experiment to demonstrate the lightbending properties of large masses was performed in 1919. And in 1936, Albert Einstein published a further prediction that immense gravitational fields would bend and focus light as an optical lens would.
Finally, you can get the same effect without a solar-sized mass.
| "How do you like my telescope?" Alice said "The whole sky?" "It's a gravity lens ... You know that a gravity field bends light? Good. I can make a field that warps light into a focus. It's lenticular, shaped like a red blood platelet. |

'And he had been sent with troops, supplies and bombs to command Russia's most trusted post, the Moonbase.'
'What is your population', I asked. 'About eighty millions.'
'THE autobus turned silently down the wide street of Hydropole. Robot-guided, insulated from noise and cold...'
'The car had no steering wheel, and no one drove!'
Now that's power walking that Hugo Gernsback would have approved.
'It was disturbing to think of the Flatline as a construct...'
'...he rewired the delivery robot so that it would serve him midnight snacks.'
'On went the electric-yacht faster and still faster.'
'...the huge vessel had spun, with a sickening lurch, through a complete half-circle, the instant the power was reversed.'
