PNothing, It's for those that do not know about it, especially at the I level here or those in later undergraduate years. Thanks Bill

Ppines-demon replied to the thread Undergrad The Power of QM and QFT.Isn’t that how we justify the whole Standard Model Lagrangian? What’s new here?

Like.
… shortly put: if it is infinite today, it was infinite then. But with a smaller scale factor. -

Just so you're aware, that is NOT necessarily true. It is possible that the universe was infinite in extent from the beginning

Ppines-demon reacted to Ibix's post in the thread Undergrad Where did the early photons go? with Like.
The universe was full of hot dense plasma, so they mostly got absorbed. Once the temperature dropped enough (some hundreds of thousands...

We won't know that for sure until we have a confirmed theory of quantum gravity. :wink:

Ppines-demon replied to the thread Undergrad Prof Mike Wiest's proposed link between quantum and consciousness.Retaking this point. So basically the only idea here is that gravitational-based collapse is maybe not like the quantum mechanics we...
