If the universe is infinite, then the big bang theory can't be correct

AI Thread Summary
The discussion centers on the relationship between the infinite nature of the universe and the Big Bang theory. It argues that if the universe is infinite now, it must have been infinite at the beginning, challenging the notion of a singular starting point. The Big Bang theory does not suggest the universe originated from a black hole-type singularity but rather describes a point where mathematical descriptions fail. The concept of singularity in this context indicates a breakdown in our understanding rather than a definitive starting point. Ultimately, the finite or infinite nature of the universe remains uncertain.

Is this true? Because if it were infinite, how would it start at a small singularity? I mean it didn't start out at a finite size then grow to infinity right?

The BB theory does not state the universe started at a black hole type singularity. The correct type of singularity is a descriptive of when the maths breaks down and no longer makes sense. We do not know if the universe is finite or infinite. If its infinite now then its infinite in the beginning

Yep, what he said.

Also, lundyjb, this exact question has been posed here before and answered the same way.

Often you can get information you want just by doing a forum search.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
