His subject was contradictory to his main point which was:
Not that you need fine-tuning for a world such as ours, but that you need fine-tuning for a universe such as ours to exist.
As to your point, it's not blind luck, but lots of time that is the key ingredient. A lot more than 20...
As a thought experiment, imagine this.
Suppose the age of the brane in which we exist is say the age we think that the "traditional" universe has existed.
Then suppose that the age of the "full", "real" universe (in which the brane resides) is such that its ratio to the age above is the...

What will happen when the CMB will raise the zero?
The zero will implode.

Of course, I have greatly simplified the concepts.
I assume he means people don't want to expend their money or time on cosmology. Isn't that the most likely meaning? Why do you think otherwise?
I take cosmology very seriously.
What is the force of "friction" (for want of a better word) between the two four-dimensional universes that have come together to create our three-dimensional surface (universe).
As a three-dimensional analog think of two rectangular solids moving toward each other.
One is moving right...
Thanks for a very clear, logical response and understanding that "it's an issue of terminology". IMHO, there is obfuscation which should be avoided and/or eliminated in many of these "cosmological" terms. Just because we don't fully understand doesn't mean that we have carte blanche to be...
I can assure you that any attitude does not originate with me.
Clarifying the terminology, then the universe is made up of:
"dark matter" energy, "dark energy" energy, and "ordinary matter" energy.
Have I got that right?
