Which is one of Edwin Hubble's findings that supports the big bang theory?
A. The universe started at a central point.
B. Planetesimals formed in debris disks.
C. Visible matter only makes up about 5% of the universe.
D. The Milky Way is the only galaxy in the universe.
Answer (2)
Edwin Hubble's findings support the Big Bang theory through his observations of distant galaxies moving away from us, which signifies that the universe is expanding. This phenomenon is evident through redshift and aligns with the concept of the universe originating from a small singularity. Hubble's work emphasizes the complexity of the universe beyond merely the visible matter we can see. ;
Edwin Hubble's observations of the redshift in distant galaxies support the Big Bang theory by demonstrating that the universe is expanding. This phenomenon led to the formulation of Hubble's Law, which states that the farther away a galaxy is, the faster it is moving away from us. Therefore, option A, 'The universe started at a central point,' is directly related to his findings.
