This chapter delves into the concept of light detection from distant objects in the universe, addressing the Olbers paradox and discussing the limit of human detection capabilities. It explores how light from various sources, including cosmic background radiation, undergoes spectral stretching due to the expanding universe, emphasizing the challenges and importance of detection thresholds.
Are black holes places or objects? Neil deGrasse Tyson and cohosts Chuck Nice and Gary O’Reilly answer grab-bag questions about distorting spacetime, Olbers’ Paradox, singularities, the shape of the universe, and more with astrophysicist Charles Liu.
