what conclusion can be drawn about the universe in the expanding balloon?
Answers
Hubble concluded that theUniverse must be expanding, like our balloon did. This conclusionlater led to the Big Bang Theory of the Origin of the Universe
The term “big bang” implies an explosion somewhere in space, with particles flying through space away from the explosion. If this were true, then with respect to the site of the explosion, the fastest-moving particles will have traveled farthest. If you plot the speed of the particles against the distance they have traveled, you will get a straight line. But this picture is NOT the concept behind the big bang. The explosion model is actually more complex than the big bang model - you need to say why there was an explosion at that point and not some other point; what distinguishes the galaxies at the edge as opposed to closer to the center, etc. In the big bang picture, all locations and galaxies are equivalent - everybody sees the same thing, and there is no center or edge.
