Question

3. What are the challenges of looking for Dyson spheres?

Answer 1

1. it is difficult to search for it . Because infrared rays will never penetrate through earth atmosphere.

2. we are unaware of how it looks like and we only know it is red and will glow . A damaged star also looks like this.

3. Dust also makes is hard to detect Dyson spheres . So we will get confused between Dyson sphere and a star surrounded by dust.

Answer 2

Answer:

A dyson sphere is a hypothetical structure, it is thought of as a way in which an advanced civilization could harness the energy of a star.

Detecting dyson spheres can be a way to find signs of life in space, since they are a sign of a civilization capable of contructing such mega structure.

The problem with detecting them is that dyson spheres surround the star, making it less visible for telescopes on Earth.

But the spheres would radiate infrared radiation, so they could be detected by infrared detectors.
