‘Ask a Spaceman’ Seeks Out the Elusive Quark Star in Finale

Posted by in categories: cosmology, particle physics

After guiding us across the universe, astrophysicist and columnist Paul Sutter closes his basic astronomy series this week by looking at the arguments for and against the existence of quark stars.

In Episode 12 of the Facebook Watch series “Ask a Spaceman,” Sutter continues to explore the topic of these stars, finishing a miniseries that began with Episode 10 and Episode 11. Scientists haven’t observed quark stars yet, but the objects may exist. Such a star would be a leftover remnant of a star that exploded and would be packed even more densely than a neutron star; the quark star would have such strong gravity that fundamental particles in the core, such as protons and neutrons, would break down into their constituent parts, called quarks.

“Is there any astrophysical scenario at all that enables them [quark stars] to appear in our universe?” Sutter asks in the new episode. At first, he suggests there might be some things we categorized a dwarf stars that are more dense and massive than what physics would suggest. So, maybe we have seen quark stars, but we can’t tell the difference between a quark star and a neutron star — they look too much alike, Sutter says.

Danish physicists claim to cast doubt on detection of gravitational waves

Posted by in categories: physics, space

“The first direct detection of gravitational waves was announced on February 11, 2016, spawned headlines around the world, snagged the 2017 Nobel Prize in Physics, and officially launched a new era of so-called “multi-messenger” astronomy. But a team of physicists at the Niels Bohr Institute in Copenhagen, Denmark, is calling that detection into question…”

“Andrew Jackson and his group have been saying for the past few years that LIGO’s detections are not real,” says LIGO Executive Director David Reitze of Caltech. “Their analysis has been looked at by many people who have all concluded there is absolutely no validity to their claims.” Reitze characterized the New Scientist article as “very biased and sensational.”

“Nothing they’ve done gives us any reason to doubt our results.”
