Scientists argue again about dark matter

Credit: Monelli & Trujillo By Popular Mechanics Last year, astronomers thought they had discovered a bizarre new galaxy that threatened to challenge the fundamental principles of physics. It does not turn out that much. Now, the galaxy, which scientists believe did not contain dark matter, looks much more normal. Scientists believe that the whole thing is a misjudgment. The first …

Scientists combine light and matter to create particles with new behavior

Photo credit: Petr Kratochvil / public domain Every atomic type in the Universe has a unique fingerprint: it absorbs or emits light only at certain energies that correspond to the allowed orbits of its electrons. This fingerprint allows scientists to identify an atom wherever it is located. A hydrogen atom in space absorbs light with the same energies as one …

Electron-behaving nanoparticles shatter the current understanding of matter

Credit: CC0 Public Domain It is not an electron. But it really does. Northwestern University researchers have made a strange and startling discovery that nanoparticles made with DNA in colloidal crystals – when they are extremely small – behave like electrons. Not only has this knowledge turned the current accepted concept of matter upside down, it has also opened the …

Revealing "hidden" phases of matter through the power of light

A new study reveals a "hidden" phase of strontium titanate. On the left, extremely fast light pulses activate atoms in the crystal structure (red arrows), which bring the material into a new ferroelectric phase. Vibrations of other atoms then stabilize the hidden phase (right fields). Picture credits: Felice Macera Most people think that water exists only in one of three …

Vera Rubin: The astronomer who brought dark matter to light

Astronomer Vera Rubin changed the way we look at the universe by showing that galaxies are mostly dark matter. On a dry and clear night at the Kitt Peak Observatory in the mountains of southern Arizona, Rubin observed the spectra of stars in the Andromeda Galaxy to determine their velocities. The conditions for the observation were perfect, if not the …
