Plasmas are by far the most common phase of ordinary matter in the universe, both by mass and by volume. [42] Above the Earth's surface, the ionosphere is a plasma, [43] and the magnetosphere contains plasma. [44] Within our Solar System, interplanetary space is filled with the plasma expelled via the solar wind, extending from the Sun's ...
Astrophysical plasma is plasma outside of the Solar System. It is studied as part of astrophysics and is commonly observed in space. [2] The accepted view of scientists is that much of the baryonic matter in the universe exists in this state. [3] When matter becomes sufficiently hot and energetic, it becomes ionized and forms a plasma.
The term plasma universe is sometimes used as a synonym for plasma cosmology, [2] as an alternative description of the plasma in the universe. [1] Plasma cosmology is distinct from pseudoscientific ideas collectively called the Electric Universe, though proponents of each are known to be sympathetic to each other .
Strange matter: A type of quark matter that may exist inside some neutron stars close to the Tolman–Oppenheimer–Volkoff limit (approximately 2–3 solar masses). May be stable at lower energy states once formed. Quark matter: Hypothetical phases of matter whose degrees of freedom include quarks and gluons Color-glass condensate
The Sun's corona, some types of flame, and stars are all examples of illuminated matter in the plasma state. Plasma is by far the most abundant of the four fundamental states, as 99% of all ordinary matter in the universe is plasma, as it composes all stars. [4] [5] [6]
The plasma of the magnetosphere has many different levels of temperature and concentration. The coldest magnetospheric plasma is most often found in the plasmasphere. However, plasma from the plasmasphere can be detected throughout the magnetosphere because it gets blown around by the Earth's electric and magnetic fields.
Space physics, also known as space plasma physics, is the study of naturally occurring plasmas within Earth's upper atmosphere and the rest of the Solar System. It includes the topics of aeronomy , aurorae , planetary ionospheres and magnetospheres , radiation belts , and space weather (collectively known as solar-terrestrial physics [ 1 ] ).
Negative mass would possess some strange properties, such as accelerating in the direction opposite of applied force.Despite being inconsistent with the expected behavior of "normal" matter, negative mass is mathematically consistent and introduces no violation of conservation of momentum or energy.
