  2. Photodisintegration - Wikipedia

    en.wikipedia.org/wiki/Photodisintegration

    Photodisintegration is endothermic (energy absorbing) for atomic nuclei lighter than iron and sometimes exothermic (energy releasing) for atomic nuclei heavier than iron. Photodisintegration is responsible for the nucleosynthesis of at least some heavy, proton-rich elements via the p-process in supernovae of type Ib, Ic, or II. This causes the ...

  3. Nuclear binding energy - Wikipedia

    en.wikipedia.org/wiki/Nuclear_binding_energy

    For lighter elements, the energy that can be released by assembling them from lighter elements decreases, and energy can be released when they fuse. This is true for nuclei lighter than iron/nickel. For heavier nuclei, more energy is needed to bind them, and that energy may be released by breaking them up into fragments (known as nuclear ...

  4. Strong interaction - Wikipedia

    en.wikipedia.org/wiki/Strong_interaction

    New physics was needed to explain this phenomenon. A stronger attractive force was postulated to explain how the atomic nucleus was bound despite the protons' mutual electromagnetic repulsion . This hypothesized force was called the strong force , which was believed to be a fundamental force that acted on the protons and neutrons that make up ...

    [75] [76] This metal is stronger than other well-known fictional metals that also exist in the game, such as Mithril and Adamant. SAM Satisfactory: Glassy purple/indigo mineral able to manipulate atomic bonds of any matter within physical contact of it when "Reanimated". Used to transform materials, and to progress through alien technology ...

  6. r-process - Wikipedia

    en.wikipedia.org/wiki/R-process

    In nuclear astrophysics, the rapid neutron-capture process, also known as the r-process, is a set of nuclear reactions that is responsible for the creation of approximately half of the atomic nuclei heavier than iron, the "heavy elements", with the other half produced by the p-process and s-process.

  7. Hierarchy problem - Wikipedia

    en.wikipedia.org/wiki/Hierarchy_problem

    In current particle physics, the differences between some parameters are much larger than this, so the question is even more noteworthy. One answer given by philosophers is the anthropic principle. If the universe came to exist by chance, and perhaps vast numbers of other universes exist or have existed, then life capable of physics experiments ...

  8. Binding energy - Wikipedia

    en.wikipedia.org/wiki/Binding_energy

    In physics and chemistry, binding energy is the smallest amount of energy required to remove a particle from a system of particles or to disassemble a system of particles into individual parts. [1] In the former meaning the term is predominantly used in condensed matter physics , atomic physics , and chemistry, whereas in nuclear physics the ...

  9. Fundamental interaction - Wikipedia

    en.wikipedia.org/wiki/Fundamental_interaction

    Electromagnetic forces are tremendously stronger than gravity, but tend to cancel out so that for astronomical-scale bodies, gravity dominates. Electrical and magnetic phenomena have been observed since ancient times, but it was only in the 19th century James Clerk Maxwell discovered that electricity and magnetism are two aspects of the same ...
