Just wait until the pupils affected by the change are old enough to actually take the PISA test.

In Safari on my Mac, I got a warning saying the security certificate could not be verified, and I could choose to simply continue. So then I got the text saying I shouldn't be able to see that site. Shouldn't the browser have actually said the security certificate had been revoked?

Exactly. Maybe I'll believe it when I see an actual universe.

Come on, why would you need 00 gauge charge cables? Just use wireless recharging!

Obviously it's an NSA backdoor.

The fastest spacecraft we built never got anywhere close to light speed. If we can somehow figure out how to get to those speeds, the univers will shrink through Lorentz contraction and, in theory, it's perfectly possible to get to another galaxy in a few hundred years. Years measured on board, that is. Of course for earth many thousands (or millions) of years will have passed.

That's exactly what I thought, why don't they all just wait until everyone's gone?

But what if nature is running on a quantum computer?

You mean Nature, the journal?

They'll just restart it from a recent backup and we'll never even know it happened. If you were to start your life again yesterday, without remembering anything from yesterday or today, the whole world including your mind restored exactly to the state it was in yesterday, then time would appear uninterrupted. So if you keep trying to generate bus errors which keep getting fixed with a reboot/restore, it will appear that none of the experiments worked and you might conclude that the universe is not a simulation. In fact, there's no way these bus error experiments would ever result in anyone concluding it is a simulation.

And then that person gets arrested and tells the police where he got the coins from.

Yes, you might make a list of all bills, where they were last spent, and try to make a pattern out of that to find the bad guy. Indeed, this technique often succeeds. But compare that to "bills" that have a record on them of every transaction ever made with them. Wouldn't you agree that that is more traceable? I never said cash is completely untraceable, I'm just saying it's wrong to say that bitcoin is untraceable when in fact it is much easier to trace than cash. I'm sure the NSA absolutely loves bitcoin.

Look at the longer term chart, and look at how similar the current drop is to the drop that occurred about a year ago. Make sure you take a logarithmic chart to see the similarity. It went from $250 down to less than $50, up and down again a few times, then up to $1000 several months later. If you bought at the peak exactly one year ago, you would still have a very nice profit today.

So what if it went from $1000 back to $400? Given the history of the prices, that's peanuts. Last year was much worse.

I would venture that the bitcoins will be easier to trace and find than the dollars/yens/whatevers. They may be in some unidentifiable wallet, but as soon as someone uses them to buy something, those bitcoins can be traced back to the illegal transactions. They may have used all kinds of trickery to disguise the transfers, but that's actually harder to do with bitcoins than with cash.

Let me guess... you're buying?
