New study of gamma rays and gravitational lensing points to the possible presence of dark matter.
- Analyzing data from the Fermi Gamma-ray Space Telescope, researchers find hints of dark matter.
- The scientists looked to spot a correlation between gravitational lensing and gamma rays.
- Future release of data can pinpoint whether the dark matter is really responsible for observed effects.
Astronomers find these five chapters to be a handy way of conceiving the universe's incredibly long lifespan.
- We're in the middle, or thereabouts, of the universe's Stelliferous era.
- If you think there's a lot going on out there now, the first era's drama makes things these days look pretty calm.
- Scientists attempt to understand the past and present by bringing together the last couple of centuries' major schools of thought.
Using permanent magnets may help to make nuclear fusion reactors simpler and more affordable.
- Nuclear fusion is the process of fusing atomic nuclei, which can unleash vast amounts of energy.
- Nuclear fusion reactors have existed for years, but none of them are able to sustainably produce energy.
- A new paper describes how permanent magnets can be used on stellarators to control the flow of super-hot plasma.
The physicist was both a gentleman and scholar.
- Robert Oppenheimer wrote a telling letter of recommendation for Richard Feynman in 1943.
- After praising Feynman's intellectual prowess, Oppenheimer used most of the ink discussing the strength of his character.
- The letter is a stark reminder of the importance of emotional intelligence.
A new study rocks prevailing theories on antimatter in the early Universe.
- Scientists from around the world teamed up to study the properties of neutrons.
- They were able to achieve extremely precise measurements of electric compasses in neutrons.
- The results challenge current theories of why antimatter and matter didn't destroy each other in the early Universe.
