Retrocausal: Solutions to the equations of Einstein's general theory of relativity known as closed time-like curves (CTCs) seem to allow a system’s trajectory to return to a previous point in time. (Courtesy: dudbrain/istock) Science fiction has long embraced the idea of travelling backward in time, but the advent of Einstein’s general theory of relativity transformed these ideas from fantasies into potential – albeit contested – realities.

Physicists create mechanical memory device from slap-bracelet-like structures

|
By Anna Demming Verified
| Physics World Verified
In today’s technologies, mechanical mechanisms generally provide the brawn while electronics supplies the brains. This is partly because it is challenging to write information into mechanical memories without resetting each bit individually. However, that could change as researchers led by Pedro Reis at École Polytechnique Fédérale de Lausanne in Switzerland and Martin van Hecke at AMOLF in the Netherlands have now found a practical means of writing mechanical bits.
