No, it doesn't at all. It's a brand new paper with a new theory that is neither LCDM nor MOND. Read the article. It's about time passing at different speeds in empty areas than in matter dense areas. What was perceived as acceleration is actually just more time passing, and things moving farther apart over that time, in low gravity areas like voids because time runs faster there.


An excerpt:


One of the biggest mysteries in science—dark energy—doesn't actually exist, according to researchers looking to solve the riddle of how the universe is expanding.

Their analysis has been published in the journal Monthly Notices of the Royal Astronomical Society Letters.

For the past 100 years, physicists have generally assumed that the cosmos is growing equally in all directions. They employed the concept of dark energy as a placeholder to explain unknown physics they couldn't understand, but the contentious theory has always had its problems.

Now a team of physicists and astronomers at the university of Canterbury in Christchurch, New Zealand are challenging the status quo, using improved analysis of supernovae light curves to show that the universe is expanding in a more varied, "lumpier" way.

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.

The model suggests that a clock in the Milky Way would be about 35 percent slower than the same one at an average position in large cosmic voids, meaning billions more years would have passed in voids. This would in turn allow more expansion of space, making it seem like the expansion is getting faster when such vast empty voids grow to dominate the universe.

Professor David Wiltshire, who led the study, said, "Our findings show that we do not need dark energy to explain why the universe appears to expand at an accelerating rate.

"Dark energy is a misidentification of variations in the kinetic energy of expansion, which is not uniform in a universe as lumpy as the one we actually live in."

Seems odd that company would expose login interfaces on the WAN side, especially with a preset password. Normally you only expose login interfaces on the LAN side, other than offering a VPN connection with a login for that.

I think the main concern with TP-LINK is that the Chinese government has access to the company.

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.

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?

Omg I got blue screened in the middle of typing this It. doesn't do it as much with the 24H2 update but it still happens every now and again.

I had read it and came away with Timescape being just an offshoot of MOND. Neither needs Dark Matter and Dark Energy.

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

That's how I always thought of it. And what I took away from that video. It's all pretty much covered in that video.
Matter, gravity, time and speed. High gravity greatly slows time. Low gravity does slow time but not as much.
No gravity time would pass unaffected. Meaning the baseline for time. Even in these voids, there is effects of gravity. Either from the local
galaxies residing in the void and gravitational influences from matter outside the void. All of it though still depends on our understanding
of gravity.

That's a definite. Started after 2009 with CPUs. That Intel Management Engine issues. AMD joined in too
AMD Secure Technology (formally called Platform Security Processor) after 2013 .
But I'm sure there's stuff nobody has discovered yet. I remember gloating about my
AMD chip from 2009 was clean of that public dubious backdoor stuff. Now
with the new AMD CPU I'm snooped on no doubt. Besides the Windows snooping.
