I know, and the question they asked:
"The universe began with a big explosion" Agree/Disagree
If big means it filled the whole universe at the time, then I'll agree to the big, but if you mean larger than an atom, then I'll disagree.
Which still leaves them to define all the other terms like 'explosion': I mean it was the beginning of space-time as we know of, so it didn't really explode because it was already everywhere, but it was rather hot, like explosions I'm familiar with. Marginally agree? maybe?
'Began'...I don't know, heard that time was different then, not really sure what you mean there. And is Universe all matter we know of, I mean, we're not in some sort of black hole in the larger unobservable universe?
