The Perseus Signal — “What We Found Could Not Be Explained by Known Physics”





"I couldn't believe my eyes," said Esra Bulbul of the Harvard Center for Astrophysics in July of 2014. "What we found, at first glance, could not be explained by known physics." Together with a team of more than a half-dozen colleagues, Bulbul used Chandra to explore the Perseus Cluster, a swarm of galaxies approximately 250 million light years from Earth. Imagine a cloud of gas in which each atom is a whole galaxy—that's a bit what the Perseus cluster is like. It is one of the most massive known objects in the Universe. The cluster itself is immersed in an enormous 'atmosphere' of superheated plasma—and it is there that the mystery resides.


A Planet Three Times the Age of Our Solar System –“Orbiting White Dwarf Star and a Pulsar”





In July 2003, Hubble helped make the astounding discovery of a planet called PSR B1620-26 b, 2.5 times the mass of Jupiter, which is located in globular cluster M4 (center of the cluster shown in the NASA/ESA Hubble Space Telescope image above). It contains several tens of thousands stars and is noteworthy in being home to many white dwarfs—the cores of ancient, dying stars whose outer layers have drifted away into space.


“The Universe is Shrinking” –A Radical Alternative to Big Bang Theory





“The field of cosmology these days is converging on a standard model, centered around inflation and the Big Bang,” says physicist Arjun Berera at the University of Edinburgh, UK. “This is why it’s as important as ever, before we get too comfortable, to see if there are alternative explanations consistent with all known observation.”


Strangely-Shaped Black Holes in 5th Dimension–“Could ‘Break Down’ the Laws of Physics”

We think of the universe as existing in three dimensions, plus the fourth dimension of time, which together are referred to as spacetime. But, in branches of theoretical physics such as string theory, the universe could be made up of as many as 11 dimensions. Additional dimensions could be large and expansive, or they could be curled up, tiny, and hard to detect. Since humans can only directly perceive three dimensions, the existence of extra dimensions can only be inferred through very high energy experiments, such as those conducted at the Large Hadron Collider.


“Bigger Than LIGO’s Detection of Gravitational Waves?” –The Discovery of Dark Matter, Argue Scientists





The discovery of dark matter, argued Carlos Frenk, Director of the Institute for Computational Cosmology, at Durham University's world-renowned theoretical cosmology research group, at the annual meeting of the American Association for the Advancement of Science, would be more important than the detection of gravitational waves, warped spacetime detected this week by LIGO scientists predicted by Einstein, born of black holes colliding.
