EXPANDING UNIVERSE. “In 2011, Vilatta conjectured that matter and antimatter repulsion could explain the acceleration of expansion of the Universe. This theoretical prediction of antigravity between matter and antimatter supports cosmological models attempting to explain the observed accelerated expansion.” https://lnkd.in/dhrW--56 View in LinkedIn

THE HYPOTHESIS. “Vilatta stated in conclusion: ‘The gravitational repulsion would prevent the mutual annihilation of isolated and alternated systems of matter and antimatter. The location of antimatter could be identified with the well-known large-scale voids observed in the distribution of galaxy clusters and superclusters.” https://lnkd.in/dhrW--56 View in LinkedIn

DARK MATTER. “Vilatta stated in conclusion: These new cosmological scenarios could eliminate the uncomfortable presence of an unidentified dark energy, and maybe also of cosmological dark matter, which, according to the Λ-CDM concordance model, would together represent more than the 95% of the Universe content. If large-scale voids are the location of antimatter, why should we not observe anything there?” https://lnkd.in/dhrW--56 View in LinkedIn

THE THESIS. “A strong case for the negative gravitational mass of antimatter and subsequent gravitational repulsion of matter and antimatter has been presented.” https://lnkd.in/dhrW--56 View in LinkedIn

TESTING THE HYPOTHESIS. “It is anticipated that the CERN ALPHA-g, G bar or AEgIS experiments will determine the effect of gravity between matter and antimatter by 2021.” https://lnkd.in/dhrW--56 View in LinkedIn

AVOIDING THE WELL TRODDEN PATH. “Galileo Galilei (1564 – 1642): ‘In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.” https://lnkd.in/dhrW--56 View in LinkedIn

THE CURIOUS MIND. “Abbé Haüy studied the behavior of a specimen of calcite when it was cleaved, and by breaking it into smaller and smaller pieces and studying the angles between the faces of the fragments, he convinced himself that the crystal was made up by the repetition of a large number of identical units.” https://lnkd.in/daJvgt2i View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on a charming paper concerned with the physics of symmetry. That said, no physicist does more than describe symmetry, unable to explain why it exists. This is true for many physical phenomena, including energy. We describe it by the work that it does but are at a loss to say what it really is. https://lnkd.in/dqXS2nnQ View in LinkedIn
