Testing the symmetry of space-time by means of atomic clocks

more »
According to Einstein the speed of light is always the same. But according to theoretical models of quantum gravitation, this uniformity of space-time does not apply to particles. Physicists have now tried to detect a change in the uniformity of space-time using two optical Ytterbium clocks.

Neural networks predict planet mass

more »
To find out how planets form astrophysicists run complicated and time consuming computer calculations. Scientists have now developed a totally novel approach to speed up this process dramatically. They use deep learning based on artificial neural networks, a method that is well known in image recognition.
