Totally. surprised experts is an oxymoron.
dark matter (just undetectable, like a neutrino field permeating the universe) might actually explain a lot of the redshift we see. but yeah it’s all mights & ifs & buts
My wife cracks up when we're watching The Universe or some similar program and some scientist makes a bold statement about how they know unequivocally how some far distant phenomenon works, then I follow up their statement with "you think". I must have said "you think" about 100 times in last night's show alone.....
