Web11 apr. 2024 · Map of Space-Time Distortions Reveals Universe’s Dark Matter Distribution, Proving Einstein Right. A new analysis of measurements of the universe’s oldest light made by the Atacama Cosmology Telescope shows how ordinary and dark matter is spread across the cosmos, backing up Einstein’s theory of gravity. By Thomas Sumner April 11, … WebIf there is a discontinuity in phase when the frequency is shifted between the mark and space values, the form of frequency shift keying used is said to be non-coherent, otherwise it is said to be coherent.In more complex schemes, additional frequencies are used to enable more than one bit to be represented by each frequency used.
