Conforme a fisica moderna, nosso universe teria começado com uma singularidade, que é caracterizada com uma densidade e temperatura infinitas. Mas se eram infinitas, poderia se extender infinitamente no passado, sem começo?
Tem muitos ateus que estão cientes, que se um criador é excluso, essa é a única alternativa, porque de absolutamente nada, nada vem. Então em vez de um criador infinito, a alternativa seria um universo, ou algo fisico, infinito.

Stephen Hawking responde esta pergunta em seu livro: 'Uma breve História do Tempo' A rigor, de acordo com a Teoria da Relatividade de Einstein, uma singularidade não contém nada que seja realmente infinito, apenas coisas que se movem matematicamente em direção ao infinito. A massa de uma singularidade é, portanto, finita, o 'infinito' refere-se apenas à matemática. Podemos ter um universo infinito, por exemplo? A resposta é não, o universo é finito. descreve o universo como sendo "finito, mas ilimitado".

Strictly speaking, according to Einstein's Theory of Relativity, a singularity does not contain anything that is actually infinite, only things that MOVE MATHEMATICALLY TOWARDS infinity. A singularity's mass is, therefore, finite, the 'infinity' refers only to the maths. Can we have an infinite universe for example? The answer is no, the universe is finite. Stephen Hawking in 'A Brief History of Time' (1989 page 44) describes the universe as being "finite but unbounded".


O tamanho do universo torna-se significativo para discussão após o processo de inflação cósmica, que ocorreu aproximadamente entre 10 elevado a 36 e 10 elevado a 33 segundos após o inicio absoluto. Ou seja, isso é Uma fração ínfima de segundo. Neste ponto, o universo passou por uma expansão exponencial, aumentando rapidamente seu tamanho por um fator enorme. Embora o tamanho exato do universo neste momento não seja precisamente conhecido, estima-se que tenha se expandido de um tamanho minúsculo comparável ao de uma partícula subatômica para talvez algo do tamanho de uma laranja ou maior em uma fração de segundo. No entanto, essas estimativas são teóricas e estão sujeitas a refinamento contínuo à medida que nossa compreensão da cosmologia melhora.

The size of the universe becomes meaningful to discuss after the process of cosmic inflation, which occurred approximately [/size]10^36 to 10^33 seconds after the Big Bang. At this point, the universe experienced an exponential expansion, rapidly increasing its size by an enormous factor. While the exact size of the universe at this timepoint is not precisely known, it is estimated to have expanded from a minuscule size comparable to that of a subatomic particle to perhaps around the size of a grapefruit or larger within a fraction of a second. However, these estimates are theoretical and subject to ongoing refinement as our understanding of cosmology improves.

17. **Galactic and Stellar Evolution (9 billion to 13.8 billion years):** Across billions of years, galaxies danced in a cosmic ballet, merging and colliding, while stars lived out their lives, enriching the cosmos with the elements necessary for planets and life to emerge.
