Q: What is the “False Vacuum” and are we living in it? Q: How would the universe be different if π = 3? Q: Is it possible for an artificial black hole to be created, or something that has the same effects? If so...
Many particles, such as electrons, pro-tons, and neutrons, behave like spin-ning tops. Unlike classical tops, however, the spin of these particles is an intrinsic quantum mechanical phenomenon. This spin is responsible for many fundamental properties of matter, including the proton's magnetic ...
The northern lights occur when electrically charged particles from the sun — mostly electrons andprotons— slam into Earth's upper atmosphere at speeds of up to 45 million mph (72 million kph), but our planet's magnetic field protects us from the onslaught. AsEarth's magnetic fieldredirects ...
Two atoms of hydrogen are combined to create helium-4 and energy in several steps: Two protons combine to form a deuterium atom (hydrogen atom with one neutron and one proton), a positron (similar to an electron, but with a positive charge) and a neutrino. A proton and a deuterium atom...
Octopus arms are incredibly strong and flexible. Made almost entirely of muscle, the arms possess the strength to wrestle sharks and to break through Plexiglas. And without those pesky bones and joints (like ours) to limit movement, the arms have an almost infinite range of motion. And yet ...
Three very different elements, each material made of only one kind of atom. The differences in matter comes down to the tiniest differences in atomic structure. TL;DR (Too Long; Didn't Read) Understand that isotopes of an element have different mass numbers but the same number of protons. ...
000 to 3.6 million degreesFahrenheit. This intense heat causes the sun to constantly release a stream ofplasma— charged particles like protons and electrons. These particles have so much energy that the sun’s gravity can’t hold them in, allowing them to escape into space as solar wind. ...
There are many different ways to produce photons, but all of them use the same mechanism inside an atom to do it. This mechanism involves the energizing of electrons orbiting each atom's nucleus. How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example,...
How is curium made? How is an electric field created? How can superconductors be used to store energy? Is graphene metallic? Why does graphene have high thermal conductivity? How are quantum computers made? Is graphene harder than diamonds? How does a cyclotron produce protons? How are fiber ...
If you boost a gas toextremely high temperatures, you get plasma. The energy begins to break apart the gas molecules, and the atoms begin to split. Normal atoms are made up of protons and neutrons in the nucleus (seeHow Atoms Work), surrounded by a cloud of electrons. ...
