Is the Big Bang theory impossible?
The Big Bang model was logically derived from the preconception that the universe is finite, together with several additional preconceptions. It assumes that the speed and range of gravity are both infinite and that there are no other forces at work beyond the scale of galaxies. The model frequently requires fixing up as new discoveries are made. The discovery of flat rotation curves of galaxies lead to the invention of dark matter (though a finite speed of gravity would also help to explain it). The discovery of accelerating expansion resulted in the invention of dark energy. In an infinite universe, there would be no large-scale warping of space-time. Expanding space suggests that turning the clock backwards might lead to a time when matter was infinitely dense, but the universe would still be infinitely large—no singularity. However, this is much too speculative when we don’t even know the cause of gravity, the speed of gravity or the range of gravity. We don’t know if other force
