The concept of dark stars, proposed in 2007, has led to significant developments in understanding the early universe. Researchers predicted the spectral characteristics of these stars, composed only of hydrogen and helium. When the James Webb Space Telescope became operational, scientists began comparing observed early universe objects with their predictions, finding that some spectra matched perfectly with dark star models. These discoveries challenge existing body of knowledge about galaxy formation, as some early objects appear too massive for the current cold dark matter model to accommodate. This indicates a necessity for further spectral analysis to definitively identify these dark stars and comprehend their role during the universe's dark ages, a period before the formation of distinct galaxies.
Did JWST discover dark stars? Neil deGrasse Tyson and comedian Chuck Nice explore the dark universe and how learning about dark matter could help uncover the mystery of JWST’s primordial objects with theoretical physicist Katherine Freese.
