Absolutely. I only buy stuff that is buy it now. All that bidding stuff is just too much trouble.
And the time machine? Since 'time' is a construct of our minds, and in physics there is no such thing per se (I am not a physicist), then check out some of the Quantum theory. Very interesting indeed. The way the math 'seems' to work, we exist not in our little 'universe', but instead in one of probably an infinite number of 'multiverse(s)'.
The physicists say that 'reality' is much more Alice in Wonderland-ish than is commonly understood. And, it is all really about math, isn't it?
Hey-this thread was already way off topic anyway.
