Of course there is disagreement about whether or not retrograde time travel is possible. Technically, physics does not forbid it, but we obviously have incomplete physics. We don't even know if there is only one time dimension, and we cannot be certain as to our spacetime topology. As far as I know, the assumption is still k=0 based on dark matter and dark energy mass contributions, but we don't really know what those are, either. So, until we can figure some of this stuff out, we won't be hopping onto extra time dimensions and circling back into the past. My advice: vote on people to support science funding (and not just applied science).

Ever heard of the Fischer–Tropsch process?

Well she is must have a pH of 1 then.

Let's not forget that motorcyclists also seem to break many of these and other rules.

I would save the money, wait 2 weeks, then watch the movie for free in the comfort of my own home with nobody to bother me. Same result, but I also get half a year's worth of groceries paid for.

Ok, someone explain this to me: people on here are all about wearing what they want, saying what they want, or, to put it more generally, expressing themselves however they want. Many also seem to be upset with decorating for Christmas too early (by their opinion) and there was also an obsession about Starbucks cups that was based on Christmas coloring. Why not support some people's expression of decorating for Christmas when they want or not caring how other people celebrate?
