Discussion Overview

The discussion revolves around the question of whether there exists a type of radiation that can penetrate all materials, including the thickest lead and concrete. Participants explore various forms of radiation and their interactions with matter, including theoretical considerations.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant questions the possibility of radiation that can pass through everything, noting that even strong forms like radio waves and gamma rays can be stopped by thick materials.
  • Another participant suggests neutrinos as a candidate for radiation that can penetrate most materials, although they acknowledge that a neutron star can stop or scatter most of them.
  • A different participant mentions gamma radiation but points out that it can be stopped by lead and concrete.
  • One participant proposes gravitational radiation as a form of radiation where absorption is negligible for all realistic objects.

Areas of Agreement / Disagreement

Participants express differing views on the types of radiation that can penetrate materials, with no consensus reached on a definitive answer. Multiple competing ideas, such as neutrinos, gamma radiation, and gravitational waves, are presented.

Contextual Notes

Participants do not clarify the specific conditions under which certain types of radiation may penetrate materials, nor do they resolve the implications of their claims regarding the effectiveness of different materials in stopping radiation.

What kind of radiation that can penetrate basically everything including thickest lead and concrete? Even the strongest radiation, so far, such as radio wave and gamma ray can be stop by thick lead and concrete. So, is it possible that there are kind of radiation that pass thru everything?

Neutrinos... :smile:

Gamma radiation can be stopped by lead and concrete.

The correct answer is "gravitational".

Gravitational waves are the only thing where absorption is negligible for every realistic object.
