Dark Matter Trace Found in Galaxy by Japanese Scientist

Here’s a breakdown of the key milestones in the study ‍of dark matter, as⁢ presented in the text:

* 1933: Fritz Zwicky ​first proposed the existence of dark matter based on observations of galaxy velocities.
* 1970s: ⁤ Vera rubin provided evidence supporting dark matter’s existence,⁤ noting that galaxy rotation‌ patterns suggested the⁣ presence of unseen matter.
* ⁢ 1990s: Cosmological simulations ⁣indicated that dark matter constitutes the‍ majority of ⁣matter in the universe.
* 2008: NASA’s Fermi Gamma-ray Space Telescope began searching ⁢for dark matter thru gamma-ray observations.
