I can provide some information about living closer to the center of the Sun or surviving inside it.
Living closer to the center of the Sun would be an extreme and inhospitable environment. The Sun's core is an intensely hot and dense region where nuclear fusion reactions occur, generating the Sun's energy. Temperatures at the core can reach around 15 million degrees Celsius (27 million degrees Fahrenheit). Any form of life as we know it would not survive under such extreme conditions.
Surviving inside the Sun is also scientifically implausible. The Sun's outer layers, including the photosphere and the convective zone, are still incredibly hot and inhospitable. Even if we were to imagine a hypothetical scenario where humans could somehow exist within the Sun without being vaporized instantly, the extreme heat, intense pressure, and the lack of a breathable atmosphere would make survival impossible.
In summary, both scenarios—living closer to the center of the Sun or surviving inside it—are not viable for humans or any known form of life. The conditions within the Sun are far beyond what our biology can tolerate. It's important to note that when we discuss living conditions for humans, we need to consider environments that are compatible with our physiology and the requirements for sustaining life.
