Are cosmic strings subatomic particles or the remnants from the big bang?

Cosmic strings are "theoretical" subatomic particles that are about one billionth of a millimeter in diameter. They are also interconnected with the big bang theory, but not simply remnants of it.
String theory has been disproved.
Comsic strings are theoretical vibrating strings of pure energy. In the most generalized explanation: The frequency at which the string vibrates determines what type of particle is formed. String theory has neither been proven nor disproven at this point. It does have some very appealing points, such as the merging of quantum and newtonian physics, and the handling of supersymmetry. However a major sticking point is the requirement for an additional 8 or so spatial dimensions(depending on the particular version of string theory you are attempting to prove), and also we are unable to directly observe a string due to the tremendous amount of energy required. In addition everything in the universe is a remnant of the big bang.

What is the leftover thermal energy from the big bang?
The radiation left over from the big bang is found in the microwave region of the electromagnetic spectrum. As the universe expanded and cooled, the intense hard gamma radiation that existed became radio waves in the low gigahertz region, characteristic of a temperature around 30 Kelvin.
How much lifetime of alpha particle?
Alpha particles are heavy (AMU 4), charged (+2), slow (0.05C) particles. As such, they have very little penetrating power (except for the very high energy varieties in cosmic rays) and they get absorbed easily into other atoms. They have very short lifetimes.
What does a quark make up?
There's no actual evidence that quarks are not fundamental particles, so as far as we know there's nothing inside them, they just are. There are a couple of half-baked theories that quarks are actually made of "strings" or "preons" (on the scale from "crackpot" to "fully validated scientific theory", strings are somewhat more "baked" than preons are), but there's no real experimental evidence for it; we're pretty much still at the level of some guy in ancient Greece saying "yeah, dude, everything is made of atoms." Except in ancient Greek, of course.
How does the Earth's magnetic field deflect charged particles?
A charged particle naturally changes direction in a magnetic field. This is because any charged particle produces a magnetic field when it is moving. And if the charged particle is moving through a magnetic field, the two fields (in this case the Earth's and the one created by the moving particle) interact to deflect the particle. The particle will be deflected "to the side" or laterally, and positively charged particles will be deflected in the opposite direction of negatively charged one.
What does radiate mean?
Radiation is the process by which energy is emitted from a source and propagated through the surrounding medium, or the energy involved in this process. Radiation consists of a flow of atomic or subatomic particles or of waves. Familiar examples are light (a form of electromagnetic radiation) and sound (a form of acoustic radiation). Both electromagnetic and acoustic radiation can be described as waves with a range of frequencies and intensities. Electromagnetic radiation is also often treated as discrete packets of energy, called photons. All matter is constantly bombarded by radiation from cosmic and terrestrial sources, and radioactive elements emit several types of radiation .
What is the contents of cosmic ray?
Cosmic rays are energetic charged subatomic particles, originating from outer space. They may produce secondary particles that penetrate the Earth's atmosphere and surface. The term ray is historical as cosmic rays were thought to be electromagnetic radiation. Most primary cosmic rays (those that enter the atmosphere from deep space) are composed of familiar stable subatomic particles that normally occur on Earth, such as protons, atomic nuclei, or electrons.Old Answer(it was a mis concept) Cosmic rays are electromagnetic rays and are thus made of mutually propogating electric and magnetic fields
What is cosmic soup?
The term cosmic soup arises in cosmology to describe a period of time very shortly after the Big Bang, when the universe is thought to have consisted of a dense mixture of subatomic particles.
What are cosmic primarily composed of?
Primary cosmic rays generally appear to be fully ionized nuclei of very massive atoms. Secondary cosmic rays are showers of various subatomic particles (e.g. muons) produced in collisions of primary cosmic rays with atomic nuclei of various gasses in earth's upper atmosphere.
What is an astroparticle?
An astroparticle is a subatomic particle of cosmic origin.
What are main components of primary cosmic rays?
Primary cosmic rays generally appear to be fully ionized nuclei of very massive atoms. Secondary cosmic rays are showers of various subatomic particles (e.g. muons) produced in collisions of primary cosmic rays with atomic nuclei of various gasses in earth's upper atmosphere.
What two phenomena that radio telescopes have revealed?
# Cosmic background radiation (remnants of the Big Bang). # Quasars.
What particles rain down continuously on the atmosphere of the Earth?
cosmic rays
Why are cosmic rays harmful to living organisms?
Because the cosmic rays consist of charged particles like gamma rays and x-rays
What are the alpha particles in the environment?
Naturally occurring alpha particles are mostly from cosmic radiation and radioactive isotopes such as Americium and Uranium.
What has the author Malcolm R Anderson written?
Malcolm R. Anderson has written: 'The mathematical theory of cosmic strings'
Is cosmic rays a type of light?
Technically, "cosmic rays" are high-energy particles rather than electromagnetic radiation. So no, they are not a type of light.
What are secondary cosmic rays?
Secondary cosmic rays are the product of collisions with primary cosmic rays. Primary ones are the kind that arrive from space and hit earth - typically air molecules in the upper atmosphere, which creates (and transfers its energy to) other particles, often creating a shower ('air shower') of secondary particles, also of high energy. Even though these products are results of collisions from within the Earth's atmosphere, they are still referred to as cosmic rays, although given the name "Secondary" cosmic rays. Note that secondary cosmic rays' composition or relative composition can differ from the cosmic rays arriving from space; particularly as new particles like muons and pions can be generated.
