Concluding that there's a fourth such relativistic particle is an extraordinary result which requires an extraordinary standard of proof. "The Planck folks have found support for the standard model of particle physics with three kinds of neutrino. "We should be sceptical about comparisons of this result with Planck's," cautioned Jeremy Mould, who has conducted important research into the Hubble Constant. More work needs to be done in order to reconcile the new study with previous research. Another was that a new type of subatomic particle, like a neutrino, travelling at near light-speed in the early universe, affected the universe's expansion rate. One was that dark energy, already shown to be accelerating the universe's expansion, could be doing so with increasing strength. The team proposed several hypothetical reasons for the discrepancy. "However, if this discrepancy holds up, it appears we may not have the right understanding." "If we know the initial amounts of stuff in the universe, such as dark energy and dark matter, and we have the physics correct, then you can go from a measurement at the time shortly after the big bang and use that understanding to predict how fast the universe should be expanding today," Riess said in a statement. The problem with the new Hubble Constant is that it is inconsistent with NASA's Wilkinson Microwave Anisotropy Probe and Planck data about the rate of the universe's expansion just after the big bang. However, getting a consensus on the Hubble Constant is not an easy task. Are we alone in the universe? Not likely, according to mathĪt the new rate of expansion, the distances between cosmic objects would be expected to double in 9.8 billion years.Hubble's bubble: Space telescope captures gorgeous Bubble Nebula.
