Jeremiah Ostriker, a leading figure in astrophysics known for his work on dark matter and dark energy, passed away at the age of 86. Ostriker's research fundamentally changed how scientists view the universe. He demonstrated that much of the universe is composed of invisible substances, now known as dark matter and dark energy, which exert a powerful gravitational influence on visible matter.
His work showed that galaxies are embedded in vast halos of dark matter, explaining why they rotate faster than expected based on their visible mass alone. He also investigated the role of dark energy in the accelerating expansion of the universe. Ostriker's research was instrumental in establishing the standard model of cosmology, which describes the universe as being composed primarily of dark energy, dark matter, and ordinary matter.
Ostriker received numerous awards and accolades for his contributions to astrophysics, including the National Medal of Science. He was a dedicated mentor to many young scientists and leaves behind a lasting legacy in the field. His insights into the dark side of the universe continue to inspire researchers today.
