“Hydrogen and helium were the first elements formed after the Big Bang.”

The evidence shows that the earliest primordial elements were hydrogen and helium, formed in the first minutes after the Big Bang. Authoritative cosmology sources consistently describe them as the first and dominant products of Big Bang nucleosynthesis. Small amounts of other light nuclides, especially lithium-7, were also produced, but that does not overturn the claim’s core meaning.

“The physical characteristics of the Big Bang resemble the geometric appearance of the interior of a black hole.”

This claim conflates a shared mathematical label—"singularity"—with actual geometric resemblance, which standard cosmology does not support. In the mainstream FLRW model, the Big Bang is a homogeneous, isotropic expansion with no black-hole-type event horizon, and its singularity structure differs fundamentally from a black hole interior. While speculative "black hole universe" hypotheses do propose such a connection, these remain contested and non-consensus. Presenting this resemblance as an established physical fact is misleading.
