In the big bang theory, there was an infinitely hot, infinitely dense singularity.
Isn't temperature the emittance of photons, and photons according to the current model, didn't exist for around 380,000 years after the big bang. So how could the singularity be hot if there were no particles to vibrate.
Am I confusing energy with temperature? can you have energy without temperature? and how can you explain density without matter.
Apologies for the stupid questions, I just want to start a conversation.
Thanks
