Happy birthday to the name "Big Bang.” Fred Hoyle, defending his steady state theory on the BBC, accidentally coined the term for the prevailing model of the early Universe #OTD in 1949. He was criticizing "the hypothesis that all matter of the universe was created in one big bang." 🧪 🔭 ⚛️ 💥

some steady state people just never came around
In a 1931 letter to Nature he articulated how this process leads to an early state where concepts like space and time break down. (2/n)

There is the "hot big bang," for which we have incontrovertible physical evidence: At some point in the far past, about 13.8 billion years ago, the universe was in an extremely hot and dense state from which expansion proceeds. (3/n)
It has many problems: dark matter, dark energy, inflationary period.
Even the famed CMB has Hubble tension.
The late Professor Colin Rourke proposed a model based on de Sitter Space with no such problems.
Hoyle's steady state theory, on the other hand, is not compatible with these observations. (4/n)

Only 11% mean “Big Bang singularity” by Big Bang.
