The steady state theory cannot explain the radiation detected in space because it suggests that the universe has always existed without a beginning or end. However, the detection of radiation provides evidence for the Big Bang theory, which states that the universe began as a single small point that exploded and has been expanding ever since.
The statement "Radiation detected in space provides evidence that an explosion occurred" best describes why the steady state theory cannot explain the radiation detected in space. The steady state theory suggests that the universe has always existed and therefore there should not have been any explosive event that could have generated the radiation.
The steady state theory cannot explain the radiation detected in space because it proposes that there is no beginning or end to the universe and that the density of the universe never changes. According to this theory, galaxies, stars, and other celestial bodies are constantly being created to replace those that burn out.
However, the existence of radiation detected in space provides evidence of an explosion called the Big Bang. This radiation is known as the cosmic microwave background radiation (CMBR) and is considered a remnant of the intense heat from the initial expansion of the universe. The CMBR is isotropic, meaning it is evenly distributed in all directions, and it is detected across the entire sky. This is consistent with the idea that the universe originated from a compact and extremely hot state.
The steady state theory does not provide an explanation for the existence of this radiation, as it assumes a constant density and no specific "event" like the Big Bang. Therefore, the statement that best describes why the steady state theory cannot explain the radiation detected in space is that the theory does not account for the evidence of an explosion, as indicated by the presence of the CMBR.
