Marilena1983 said:Which particles arrive from space and pass through the earth?
How is this possible?
Are they called neutrinos?
Marilena1983 said:is it because they have little mass and no charge? So this means they would have limited interaction with heavier charged matter?
Marilena1983 said:it says that they are electrically neutral and that they travel at the speed of light.
i don't really understand what it means about "neutrinos traveling through matter undergo a process analogous to light traveling through a transparent material"
Neutrinos interact with the nuclei, or more particularly the nucleons, in matter via the weak force. Consider the size or volume of the nucleus compared to the size of the atom. Ordinary matter is rather transparent to neutrinos.Marilena1983 said:it says that they are electrically neutral and that they travel at the speed of light.

Particles from space refer to any type of matter that originates from outside of Earth's atmosphere. These can include cosmic rays, solar wind, and interstellar dust.
Particles from space can come from a variety of sources, such as the sun, other stars, supernovae, and even distant galaxies. They can also be created through interactions between cosmic rays and Earth's atmosphere.
Particles from space can have a variety of effects on Earth, depending on their type and intensity. They can contribute to the Earth's atmospheric and magnetic processes, influence weather patterns, and even cause disruptions in communication systems and power grids.
Some particles from space, such as high-energy cosmic rays, can pose a risk to human health if exposed in large doses. However, Earth's atmosphere and magnetic field provide protection from most of these particles, and scientists continue to study their potential effects on human health.
Scientists use a variety of tools and techniques to study particles from space, including telescopes, satellites, and ground-based detectors. They also conduct experiments in space and analyze data collected from missions to better understand the behavior and effects of these particles.
