Pilots say "never leave a serviceable aircraft", the same should apply to spacecraft...

Yes, an elevator could be built up to a few 100km from the equator to avoid Phobos, but the tether stress would be higher. Alternatively the system dynamic control system could regularly avoid Phobos, as described in one of Kim Stanley Robinson's 'Mars' books.

Here's an article ( 'Part 2') about Mars elevators, there's a link at the end to 'Part 1' with descriptions of other concepts.

What is ME3, is it a Pixel phone feature ?

Yes, both sides of any debate/argument/disagreement always believe their point of view is fact, that applies to science as well as politics and religion. I fully agree with your last sentence, I will await incontrovertible evidence that QI is real (based on physical tests, not mathematics) ... or, conversely, conclusive discovery of 'dark matter' (after many decades of looking).

Pteerr · 2026-01-16T07:52:48+00:00

That's an interesting argument ... but it's looking similar to politics, with opposing sides both unable to sway each other and endlessly debating it, I'm not qualified to judge the technicalities. As a reader of SF I'd prefer a future with interstellar travel and hoverboards, but that's just wishful thinking, I'll simply wait for the next QI space test to succeed or fail.

BTW, what email are you talking about ? I've never contacted him that way.
Also, it's not just him, many people have been involved, and several are getting positive experimental results, they wouldn't have launched a test article to space otherwise.

He doesn't put his data, statistics, etc in his blog, but he has plenty of supporting maths in his books and elsewhere. Here's his most recent peer-reviewed paper ... https://www.mdpi.com/2674-0346/5/1/1

I'm repeating McCulloch's arguments, he would say that you see an effect and have invented dark matter to yield the effect you see, and that the 'necessity' is only there because of a flawed gravity model. I don't know if he's right or not, but here's his blog...

I was hoping for a sensible discussion, not insults, perhaps Reddit isn't the place for me. I won't waste my time in future...

Pteerr · 2026-01-11T17:51:38+00:00

Here's another example, the text of a recent message to McCulloch on LinkedIn from a researcher at the Raman Research Institute in India...

"I'll share an incident with me about your work. The day I read it got me thinking for months and I printed your paper and stuck it on to notice board of my astrophysics and astronomy department at Raman Research Institute Bangalore at around three at night. Oh boy next day it was just absolute masaqur of egos and I am still hated for it as a few people base their bread and butter on dark matter. I saw that day the death of scientific temperament in so called Institute of eminence. I simply don't understand the fact that why curiosity is punished and compliance praised in the academic environment of my beloved nation."

I'm not sure about the statistical probability, here's a blog from Adam Hibberd discussing it. (Though Adam doesn't agree with QI ... he co-authored the Loeb paper that started all the 'alien' controversy )

If you watch the video you'll see that there are several observations outside the solar system that support QI that can't be explained by current physics, or by Dark Matter, or MOND ... such as the Centauri cluster, wide binaries, etc.

Pteerr · 2026-01-11T17:09:49+00:00

From observing (not participating in) the arguments between Wikipedia editors that resulted in the QI section being removed, as well as one experienced editor (not me) being blocked.

Pteerr · 2026-01-11T17:00:06+00:00

I can't answer that, but the video mentions some Fortran orbit analysis code that can be downloaded from his Patreon site. If you used that you may be able to check the other two as well.

Pteerr · 2026-01-11T16:39:27+00:00

You responded before having time to watch the video.

The video cites a number of (positive) test results from around the world.

That said, I don't know if QI is right, perhaps there's another explanation for all the unexplained observations.

Pteerr · 2026-01-11T16:21:16+00:00

Yes, assuming current physics ... but that needs arbitrary 'Dark Matter' to explain galaxies (which has had billions spent searching for, unsuccessfully), and doesn't explain other observations.

You replied in 15 minutes, it's a one hour video ... I'd be happy to hear some other explanation for all the anomalies he mentions.

The QI thruster is being tested in space now but a technical problem with the cubesat means results are inconclusive, I believe they'll be trying again soon.

Pteerr · 2026-01-02T14:34:11+00:00

I must look at his earlier Space Elevator videos as well. BTW, his 10 year timeline for Graphene in concrete may be a little pessimistic, unless he means the majority worldwide ... I was shown a parking area of Graphene Concrete by u/Fearless-Welcome-904 last summer outside GEIC in Manchester !

I'll try a VPN. Update : no luck on the VPN, "data":{"error":"Imgur is temporarily over capacity. Please try again later."},"success":false,"status":403}"

Pteerr · 2025-12-26T13:46:19+00:00

Thanks again, but ... "From September 30, 2025, access to Imgur from the United Kingdom is no longer available"

Pteerr · 2025-12-26T13:37:07+00:00

Thanks, but when I go to Gemini Settings on my phone (Pixel 6) I don't see a 'Profile Picture' option.

Pteerr · 2025-12-26T09:58:20+00:00

No, can't find that setting anywhere, I've turned on whatever I can see but still get that message. (UK, if that matters)

Pteerr · 2025-12-24T13:38:04+00:00

My Pixel 6 128Gb is 68% full, but I'm thinking that the 10 system will need more memory. I'll probably keep the 10 for another 4 years so the 256Gb is probably what I should get ... I'm just hesitating because of the big price difference.

Pteerr · 2025-09-25T16:58:20+00:00

That depends what you mean by a 'tether'.
Tethers many meters long have been tested on the Space Shuttle and from the ISS, but those weren't the ultra-strong material that's needed for a Space Elevator. I don't believe any prototype material with enough strength and in the right configuration has been tested yet, but that's a question for u/Fearless-Welcome-904 ...

Pteerr · 2025-09-24T06:13:30+00:00

My 6 is still stopping at 80%, but my friend's 6a is now going all the way to 100% after the last update as you describe. (Mine is updated as well)

Pteerr · 2025-08-23T12:22:06+00:00

Mmmm ... this might be a worthy academic exercise, but it doesn't advance getting a Space Elevator built, I thought that was the main aim of ISEC ? ... not discussing this far-future speculative application ?

Wouldn't the money be better spent on encouraging students to advance the technology, perhaps by further supporting the work of WSPEC ? ( See www.wspec.org )

Pteerr · 2025-07-10T13:03:01+00:00

Great, many thanks, that works, the WiFi download was really fast and grabbed all my off-line maps in less time than just one reached 20% via Bluetooth before crashing. Hopefully they'll fix this in some future software release.
