The net loss is the only number you really need to know. You can deduct $3,000 against your income and carry the rest over to deduct next year.

Wash sale Loss Disallowed happens when you sell at a loss and buy the same thing again within 30 days (before or after). It means that loss doesn't count for taxes, but if you sell the position later (for more than 30 days) you get the loss back again (because the amount that was disallowed before gets added to the cost basis).

I'm guessing you got screwed by a wide bid/ask spread. Basically, every stock has bids (offers to buy) and asks (offers to sell) at various prices. The bids are always below the asks (because if they cross over a trade happens and those offers go away). Usually, the difference is so small that we talk about a single price, but in thinly trades stocks it can be significant.

Next time use a limit order (or just don't trade penny stocks).

The theory doesn't say that the universe was gathered together and then started to expand at some point. The theory only goes back to a time when the universe was very dense and hot and already expanding rapidly. Before that, we simply don't know, because we don't have a theory of quantum gravity.

The "big bang" theory is just this: we observe the universe expanding, so we extrapolate backwards and believe at one point the universe was very dense. We don't know what happened before that.

There is other evidence that the universe was very dense in the past, like the cosmic microwave background radiation. It's a well established theory.

As you might notice, it does not explain where the universe came from. And it also isn't incompatible with belief in God.

(I don't believe in God, but that's not because I have an evidence-based answer for where the universe came from, but because I don't see evidence that the answer is necessarily God.)

Or it will mean the same number of software developers can write a lot more software.

The demand for food is relatively fixed (inelastic), so more productivity leads for the most part to fewer farmers rather than more food. That hasn't been the case for software with past productivity improvements.
