WWK:. Earth based scientists!. One of the most modern influential geologists is a man by the name of . Alfred Wegener.. He developed the theory of continental drift. And thus laid the groundwork for modern plate tectonics knowledge.. Mr. Ross Brown. Brooklyn School for Law and Technology. Aim: How did early astronomers study our universe?. 21 March 2016. Do now: What evidence do you have that our Earth is round? Use “naked-eye” observations.. A ‘finger’ of the Universe’s dark-matter skeleton, which ultimately dictates where galaxies form, has been observed for the first time. Researchers have directly detected a slim bridge of dark matter joining two clusters of galaxies, using a technique that could eventually help astrophysicists to understand the structure of the Universe and identify what makes up the mysterious invisible substance known as . Hubble Expansion and the Big Bang . The fact that more distant galaxies. have higher . redshifts. . indicates that the universe is expanding. This implies that the universe was born in a huge explosion, or . From t=0 to the CBR Era. The CBR. Universe hotter & denser in the past. For T high enough - ionized & opaque – blackbody. and. Currently T=2.726 K. z(opaque. . transparent)~1100 K. The universe is the sum of all energy, matter, space and time.. But there. ’. s a difference between the universe we see (the observable universe) . and the universe as it really exists.. This gets complicated…..
