Dark matter may come in multiple particles and weights, similar to the ordinary elements on the periodic table, a new theory suggests. When you purchase through links on our site, we may earn an ...

Those particles, they propose, aren’t lightweight at all and could come in all kinds of “species” — with their own “dark matter periodic table” of invisible elements, originally formed ...

The numbers of subatomic particles in an atom can be calculated from its atomic number and mass number. The periodic table - AQA Mendeleev made an early periodic table.

In due course, a number of trans-uranium elements were detected by means of bombardment with particles, which resulted in creating atoms of the next higher element on the periodic table. Today ...

The number of subatomic particles in an atom can be calculated from the atom's atomic number and mass number. The periodic table - AQA Mendeleev made an early periodic table.

Naturally occurring superheavy elements beyond those listed in the periodic table could potentially explain why asteroid 33 Polyhymnia is so dense, new research suggests.

The periodic table of the chemical elements is a tabular method of displaying the chemical elements, first devised in 1869 by the Russian chemist Dimitri Mendeleev. Mendeleev intended the table to ...

Those particles then got trapped into ultradense pockets. Some of those pockets splintered off to become black holes, which then dissolved into a shower of multiple dark matter particle "species," ...

Nov 13, 2023 13:00:00 Dark matter may have its own invisible periodic table of elements, the key is the ``primordial black hole'' immediately after the Big Bang ...
