Several "high-profile astronomers" will meet at London's Royal Society (the UK's national academy of sciences), "to question some of the most fundamental aspects of our understanding of the Universe.reports Futurism: As The Guardian reports, the luminaries of cosmology will be re-examining some basic assumptions about the universe — right down to the over-a-century-old Theory that it's expanding at a constant rate. "We are, in cosmology, using a model that was first formulated in 1922," coorganizer and Oxford cosmologist Subir Sarkar told the newspaper, in an apparent reference to the year Russian astronomer Alexander Friedmann outlined the possibility of cosmic expansion based on Einstein's general theory of relativity. "We have great data, but the theoretical basis is past its sell-by date," he added. "More and more people are saying the same thing and these are respected astronomers." A number of researchers have found evidence that the universe may be expanding more quickly in some areas compared to others, raising the tantalizing possibility that megastructures could be influencing the universe's growth in significant ways. Sarkar and his colleagues, for instance, are suggesting that the universe is "lopsided" after studying over a million quasars, which are the active nuclei of galaxies where gas and dust are being gobbled up by a supermassive black hole. The article notes that another theory is that the so-called cosmological constant that's been used for decades "actually varies across space."
