Transients in the Palomar Observatory Sky Survey (POSS-I) may be associated with nuclear testing and reports of unidentified anomalous phenomena
TL;DR
Imagine you're looking through old photographs of the night sky from the 1950s and you notice bright dots that appear in some pictures but not others - like stars that blink on and off. Scientists found hundreds of these mysterious "transient" objects in photos taken before any satellites existed. When they compared the dates these objects appeared with historical records of nuclear bomb tests and UFO reports, they found some surprising patterns: these mystery objects were 45% more likely to show up around the time of nuclear tests, and on days with more UFO reports, there tended to be more of these sky objects too. It's like finding that lightning tends to happen more often during thunderstorms - the connection might mean something important, even if we don't know exactly what yet.
Transient star-like objects of unknown origin have been identified in the first Palomar Observatory Sky Survey (POSS-I) conducted prior to the first artificial satellite. We tested speculative hypotheses that some transients are related to nuclear weapons testing or unidentified anomalous phenomena (UAP) reports. A dataset comprising daily data (11/19/49—4/28/57) regarding identified transients, nuclear testing, and UAP reports was created (n = 2,718 days). Results revealed significant (p = .008) associations between nuclear testing and observed transients, with transients 45% more likely on dates within + /- 1 day of nuclear testing. For days on which at least one transient was identified, significant associations were noted between total number of transients and total number of independent UAP reports per date (p = 0.015). For every additional UAP reported on a given date, there was an 8.5% increase in number of transients identified. Small but significant (p = .008) associations between nuclear testing and number of UAP reports were also noted. Findings suggest associations beyond chance between occurrence of transients and both nuclear testing and UAP reports. These findings may help elucidate the nature of POSS-I transients and strengthen empirical support for the UAP phenomenon.
- 1Transients were 45% more likely to occur on dates within +/- 1 day of nuclear testing, with 18.5% of days following nuclear tests showing transients compared to 11.0% on unassociated days
- 2For every additional UAP reported on a given date, there was an 8.5% increase in the number of transients identified
- 3Significant associations were found between total number of transients and total number of independent UAP reports per date (p = 0.015) on days when at least one transient was observed
- 4Small but significant associations between nuclear testing and number of UAP reports were also noted (p = 0.008)
- 5Multiple bright transients were observed in POSS-I images from July 19 and 27, 1952, coinciding with UAP sightings over Washington D.C. during those same weekends
Single-minus gluon tree amplitudes are nonzero
Imagine tiny particles called gluons are like spinning tops. Their spin can be in one of two directions, which physicists call 'plus' or 'minus'. For decades, the rulebook seemed to say that you could never have a situation where just one gluon was spinning 'minus' and all the others were spinning 'plus' — that outcome was thought to be zero. This paper found a loophole. Under very specific, purely mathematical conditions that don't exist in our physical reality but are useful for calculations, this interaction can happen. The researchers wrote down the exact recipe for it, fixing a small but important detail in our fundamental rulebook for how the universe works.
Sub-part-per-trillion test of the Standard Model with atomic hydrogen
Scientists made an incredibly precise measurement of light emitted by hydrogen atoms that tested one of physics' most fundamental theories - the Standard Model - to an accuracy of 0.7 parts per trillion. This measurement also resolved a long-standing disagreement about the size of protons by confirming the smaller value found in previous experiments with exotic atoms.
Rock art from at least 67,800 years ago in Sulawesi
Imagine finding a spray-painted handprint on a cave wall. Over thousands of years, a thin, glassy layer of minerals, like limescale in a kettle, grew on top of it. Scientists used a high-tech laser to analyze that mineral layer. By measuring the natural radioactive decay of elements within it, they figured out the layer is about 71,600 years old. Since the handprint is underneath that layer, it must be at least that old, with the most conservative estimate being 67,800 years. This makes it one of the oldest pieces of art ever found and proves that the early humans who lived on this Indonesian island, who had to cross the ocean to get there, were creating symbolic art.
An interstellar energetic and non-aqueous pathway to peptide formation
Imagine you have a box of LEGO bricks, which are like the basic molecules of life called amino acids. To build anything, you need to snap them together. Scientists used to think you needed a puddle of liquid water to make the bricks 'click'. This experiment is like discovering you can snap the LEGOs together inside a freezer. The researchers took the simplest amino acid, froze it onto a dust grain like you'd find in space, and zapped it with energy that mimics cosmic radiation. They found that the amino acids linked up to form a two-brick chain, the first step towards building a protein. This means the essential first chains for life could be forming all over space and delivered to new planets by comets and asteroids.
