How Big The Universe 🌌 REALLY Is? w/Brian Cox #cosmology #universe #briancox

How many galaxies are in the Universe? How big is the Universe? How big is the Milky Way galaxy? How many stars are in the Milky Way galaxy? Join physicist Brian Cox as he talks about the scale of the universe and the possibility of an infinite universe. He starts by visualizing the scale of our universe. He adds that there are something like 2 trillion galaxies in the observable universe, which we came to know after the study of the “LOCAL UNIVERSE.“ Moreover, he talks about how it would take 100 hundred thousand years to cross a galaxy like our Milky Way, and there are estimates of 400 billion stars in the Milky Way galaxy. At the end, he talks about one of the possibilities of our universe being infinite. #cosmology #universe #astronomy #astrophysics #galaxy #milkyway #science
