Daan Meerburg - Publication in NATURE International Journal of Science
In March of last year, a small collaboration operating the EDGES experiment in Australia claimed the first detection of light originating from the cosmic dawn (when the Universe was about a tenth of its current size).
This remarkable discovery was complemented by the fact that the signal appeared very different from what (simple) physical models predicted. Foremost, the amplitude of the signal is much larger then expected from standard physics. In addition, the shape of the signal did not match any current models. The conclusion was then that the signal indicated new physics, which has led to a flood of papers in the wake of the discovery.
Daan Meerburg and three collaborators at Cambridge University re-analyzed the EDGES data and found several serious concerns with the existing analysis. They put serious doubts on both the detection as well as its interpretation as a signal of new physics. The results were published in nature, as a letter of brief communication.
