"All fiction is propaganda, and the fiction we like is the propaganda we believe in, and the fiction we don't like is the propaganda we don't believe in."
- Samuel R. Delany

| 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. |
