What was it like when cosmic inflation occurred?

<p>Our Universe today is full of matter and radiation, and can be observed by us through a variety of means. Atoms have clumped and clustered together due to billions of years of gravitation. This has formed a great cosmic web on the largest scales, with clusters of galaxies, individual galaxies, clouds of gas, stars, planets, and more on smaller scales. Through it all, the Universe has been expanding and cooling, something it&rsquo;s been doing since the earliest moments of the hot Big Bang.</p> <p>But&nbsp;<a href="https://bigthink.com/starts-with-a-bang/evidence-universe-before-big-bang/" rel="noopener ugc nofollow" target="_blank">the Big Bang wasn&rsquo;t the very beginning of the Universe</a>.
