Imagine inflating a balloon; as the diameter increases, every point on the surface of the balloon sees the other points moving away as if it were in the center of the expansion. ” This is because one is living in a two-dimensional world (the surface of the balloon). As soon as the inhabitants of a point perceive what is happening in the three-dimensional space, in which the balloon is expanding, they understand (as general relativity has made us understand in the real universe) that all the points on the surface of the balloon appear to be at the center of the explosion.

However, it was necessary to wait until the end of the 1920s to understand that a static model of the universe was not viable. Even Einstein, when he wrote the equations of general relativity, found that they were incompatible with a static universe but, instead of imputing this to his image of the universe, he preferred to think that there was a mistake in his equations. He therefore introduced what he called the “cosmological constant,” which could maintain a static universe by countering the effect of gravity.

1). For 10 days, the instruments on board “photographed” the universe as it appeared 380,000 years after the Big Bang, making use of a characteristic of the south-polar launch site: stable, high-altitude winds that blow for months along a circular path around the pole. The balloon, subject to these winds, returned after 10 days to the point where the flight started, allowing its precious cargo to be recovered. The experiment was named Boomerang, because of its circular flight path. 6 shows the balloon before the launch.
