Neil Turok on the Quantum to Cosmos Festival

Neil Turok, director of theoretical physics at the Perimeter Institute, joins The Agenda to talk about the allure of physics and how it can help us predict the future.

@nubbs @shk9664 Angels and pinheads. We have observational data going all the way back to about 370,000 yrs after the BB. From that and observations of the results of BB Nucleosynthesis, we pretty much know what the universe looked like going back to a ~1 sec after the BB. It's silly to split hairs over what any physicist says when addressing a lay audience. It's over-simplified. In a very real way, the physics *is* the math. And most lay people are math-illiterate, especially in the US.

i greatly enjoyed this, my goal is to perform research at perimeter in 9 years.

pss my condolences on having to live in waterloo, especially during the winter (no wonder physicists refer to the PI as being siberia)

[nubbs]

ps "straw man argument" - is that like saying you are correct because you are geographically closer to turok than i am?

im guessing physics isn't your major, is it? maybe you should take advantage of your proximity to the PI and actually sit in on some of their public lectures. you might learn something - like how light was created millions of years after the big bang, and that everything that expanded before light remains forever invisible - hence turok saying "the KNOWN VISIBLE universe"

[nubbs]

1 - you said i made a "straw man argument", but were completely unable to explain how

2 - yes, i am saying that you are wrong - he very specifically said "known visible universe". i correctly quoted him. you did not.

3 - "ergo that neil turok is also wrong" ... um, what? i never contested anything turok said. only that there is a big difference the visible universe and that which remains hidden (dark matter for one)

4 - i suggest you sit in on an intro cosmology course

@nubbs

So what is ur argument, that im wrong, ergo that neil turok is also wrong. So you must be saying that your right? Aside from all this i am sitting 5 minutes away from the PI building where his office as well as Steven Hawking office is also located. Should i expect to find you in that building?

@shk9664

listen again to what he says - "we have mapped the known visible universe". the universe existed before photons condensed to give us the light we need to see back into the early universe.

[shk9664]

This sounds like a straw man arguement. He said we can see the whole universe. he says that we can see the whole universe not the whole visible universe.
