I bet a lot of the James Bond stuff today goes on at router factories. If you can get access to routers in the factory/the manufacturing process, you can put hardware (not just firmware) backdoors on the boards. I think China was caught doing that a year or two ago.

The new evidence supports the "timescape" model of cosmic expansion, which doesn't have a need for dark energy because the differences in stretching light aren't the result of an accelerating universe but instead a consequence of how we calibrate time and distance.

It takes into account that gravity slows time, so an ideal clock in empty space ticks faster than inside a galaxy.

Isn't this just how the formule works.

speed = m/s(t)

If you want to explain why a distance is longer (in empty space), make the time smaller (faster time) and the speed increases.
Or inside a galaxy the distance is shorter, so make the time larger (slower time) and the speed decreases.

So time is the variable. But why? Only because of gravity?
