To study the private lives of objects in the microscopic realm (and beyond), scientists often rely on extremely bright light sources. Free-electron lasers, which achieve the best results, accelerate electrons several kilometers to the speed of light, pass them through a large magnetic hall, and shake free intense pulses of photons that illuminate materials for … Read more
By Light Publishing Center, Changchun Institute of Optics, Fine Mechanics and Physics, CAS October 19, 2023 Researchers developing quantum teleportation have set a speed record of 7.1 qubits per second, using innovative technology and overcoming previous limitations, marking a major step toward an efficient, large-scale quantum internet. Quantum teleportation allows the transmission of quantum information … Read more
Time travel. We’ve all thought about it at one time or another, and the topic has been explored extensively in science fiction. From time to time, this is the subject of scientific research, usually involving quantum mechanics and how the four fundamental forces of the Universe (electromagnetism, the weak and strong nuclear forces, and gravity) … Read more
TThe James Webb Space Telescope posed problems for the big bang theory. The idea that stars and galaxies gradually coalesced after a big bang faces serious problems. There is no evidence that small, simple galaxies gradually evolved into large, complex galaxies. In contrast, the first galaxies were as large and complex as they are today. … Read more
In June, an IBM computing executive claimed that quantum computers are entering a phase where high-tech experimental devices are useful. In September, Australia’s chief scientist Cathy Foley went so far as to herald the dawn of the quantum era. Australian physicist Michelle Simmons this week won the nation’s top science prize for her work on … Read more
After Carl Wieman won the Nobel Prize in physics in 2001 for shining lasers on atoms in a new way that he said experimentally proved Albert Einstein’s theory, Wieman decided to change his research focus. He devoted much of his time and energy to learning ways to improve teaching. I could just make a bigger … Read more

It seems like such a simple idea that no one has ever done it before: plot everything from subatomic particles to superclusters in a table of masses and radii. Now there are those who think the results raise some very interesting and perhaps a little disturbing questions. The diagram is the work of Dr Charles … Read more
