Light alone cannot create a black hole

  • 2 תגובות
Researchers from Canada and Spain have demonstrated for the first time that black holes cannot be formed from the compression of electromagnetic radiation alone. The reason for this lies in a quantum effect that converts energy into particles that scatter from the compressed area and prevent the light from collapsing

Remember how hard it was to find a single Higgs boson? Try to find two at the same place and time. This fascinating process, called Higgs pair production, can provide scientists with information about the self-interaction of
This is how induction cookers work, including a cross-section showing their interior. The figure shows the following components: the ceramic glass surface, the induction coil below it, the power supply unit, a ferromagnetic pot on the stove. The arrows in the figure indicate the magnetic field created by the induction coil and heating the pot. The image was prepared using DALEE and is not used as a scientific image. The text that appears in it is also in the best DALEE tradition "about".

Why is the mass of the Higgs particle lighter than expected?

Researchers have built a model according to which the mass of the Higgs boson, which helps produce the mass of elementary particles, changed in the early universe, and is therefore much smaller than the standard model of particle physics describes

The active layer of the laser - a single atomic layer - is on the resonator. The laser beam is split into two beams by the opposite spins of the photons (light particles), which can be controlled with the help of the laser pump (credit: Scholardesigner co, LTD).
