The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...

A team of UCLA electrical and computer engineers has created a physical artificial neural network — a device modeled on how the human brain works — that can analyze large volumes of data and identify ...

A distance-time graph shows how the distance travelled by an object changes over time and can be used to calculate the speed of the object. A sloping line on a distance-time graph shows that the ...

Using ultra-fast laser pulses and special cameras, scientists have simulated an optical illusion that appears to defy Einstein's theory of special relativity. One consequence of special relativity is ...

Speed is a measure of how fast an object is moving. Calculate speed using the speed equation - speed = distance divided by time. The speed equation can be rearranged to find distance travelled and ...

An experiment has visualized a prediction about objects traveling at the speed of light known as the Terrell-Penrose effect, first made over 60 years ago. When an object approaches the speed of light ...

Scientists have created a 3D printed artificial neural network – a device modelled on how the human brain works – that can analyse large volumes of data and identify objects at the speed of light.
