So now what the bad guys have to to after tampering with audio recordings is to subtract the hum of the mains and add the hum at a different time. ?

Seven billion light years away (seven billion years ago)
I may not have this right, but due to the expansion of space, wouldn't it have been closer than seven billion light years away at the time of the kaboom? And if the light's taken seven billion light years to get here, space will have expanded further, so the remnants would now be further than seven billion light years away. Right?
Or is this the sort of thing where you can be specific about the distance, or the time, but not both?
Wikipedia has an answer, but I think the above is just meant to give the layman some rough understanding of what's going on.
Beware that it is extremely difficult to measure these kinds of distances exactly. The figure may be a few orders of magnitude wrong,
so whether you take into account the expanding universe or not may not be that important...
Cosmologists measure everything in gigaparsec. 7b light years is only 0.3 GPc so it may not be that important.
Because i don't know any storage media that's in liquid or gaseous form, or a plasma.
I, for one, store all my digital stuff in the Bose-Einstein condensate phase of matter on my shiny new quantum computer
Well, I trust both Google and Dropbox enough to store my encrypted backups. Wouldn't upload anything important without encryption though.
I run OpenWRT Backfire on my TP-link WR1043. It even comes with an USB port.
It's MIPS based, comes with 32 MB ram and a gigabit switch etc.
Can only recommend.
Well, something has to explain what we observe in the lab.
So far, quantum physics is the only successful theory.
In wind power, yes, you use rare earth materials. But at end of life, these can be recycled. It's not like we throw
the rare earth materials into space when we're done with them.
Solar power uses ground water in deserts. Does this even run out? I mean, ground water is there because it rains or comes in from the sea.
Evaporating water from solar panels still make it into rain and so the cycle should continue.
What's the fuss?
