I don't understand that. Playing Flerfs advocate, what I see is real, NASA fake.“You uninstalled the sky”. Love it!![]()
Yeah but what if it's just a projection, not a real heavenly body?I don't understand that. Playing Flerfs advocate, what I see is real, NASA fake.
I have flipped on this issue.
At first, I declared they are all just trolls. But I am concluding that this is part of a larger, more coordinated effort to sow misinformation and doubt in science and western establishment.
(Not exactly a new idea, but I'm connecting the dots now). I see religious fundies and non-western actors had both having strong motives to undermine education and critical thinking. And, ultimately, it's working: it contributed to getting Trump elected.
IOW, I'm beginning to think that flerfers and hoaxers and creationists of all kinds are not just fringers- they're a threat that are ignored at our peril.
Perhaps a bit of both.I am wary about inferring a conspiracy when simple ignorance and incompetence are more than enough on their own to adequately explain most of what we see.
Sort of validates the actions of the Australian Albanese led government and their new social media age restriction laws. The amount of doubt about an oblate spheroidal shaped Earth, and the manned Moon landings on facebook when I was frequenting the place, was pretty unsettling to me. And a sizable proportion were Aussies had me even more perplexed.Yep. The Internet Research Agency, which is the troll farm in St. Petersburg, has been sending out flat-Earth content via its bots since 2015. These show up on Facebook, Instagram etc. The Russians know that a conspiracy-addled US is a weaker US.
Yikes!It is growing fast. In 2021, 19% of Americans either thought the Earth was flat or thought it might be flat. In 2025 it was up to 24%. (Source - Polar, Environment, and Science (POLES) Survey, by the Carsey School of Public Policy.)
Ok we could blame NASA for faking the moon in the 1950s, with some very big and very clever OHP, what about before that?Yeah but what if it's just a projection, not a real heavenly body?
There, you see? Now you are arguing about it!Ok we could blame NASA for faking the moon in the 1950s, with some very big and very clever OHP, what about before that?
The moon features in literature and art all the way back to Genesis.
No I just see it as an argument flerfs would not use because of that reason.There, you see? Now you are arguing about it!![]()
That is so alarming I almost don't believe it.It is growing fast. In 2021, 19% of Americans either thought the Earth was flat or thought it might be flat. In 2025 it was up to 24%. (Source - Polar, Environment, and Science (POLES) Survey, by the Carsey School of Public Policy.)
More alarming than Americans voting Trump in twice?That is so alarming I almost don't believe it.
Zigackly.More alarming than Americans voting Trump in twice?
Did he take you up on your suggestion and walk 30,000 miles?At one time while debating a religious ratbag, claiming the earth was irrefutably flat, ( as per some questionable obscure bible passage) I asked him to walk directly 10,000 miles in a straight line on the Earth's surface, then make a 90 degree turn, walk another 10,000 miles, make another 90 degree turn back, and walk another 10,000 miles, you will be back where you first started, having traced out a triangle. Even the most basic education in geometry will tell you that is impossible on a flat surface. . Couple this with the equally crazy buffoonish claims of "we never landed on the Moon" and vaccination denialists, and it seems to me that some simply have a distaste for science and authority. Then they (in the USA) decide to vote for Trump. Then of course we have social media where people are allowed to express whatever nonsensical claim they are liable to pull out of their arse!
I'm not really sure. being the religious ratbag that he was, he may have.Did he take you up on your suggestion and walk 30,000 miles?
Kermos:
Oh, goody! Yes, let's!
Close enough.
Now, here's what you need to know, Kermos:
With ground-based telescopes, we can reliably measure angles down to about 0.01 arcseconds, which is consistent with what I told you earlier about Polaris being at around the limit of the parallax method. We're using the Earth's orbit as the baseline for the measurement here, of course.
With space-based telescopes, that limit can be pushed down by an additional factor of about 10, meaning that we can reliably measure angles down to 0.001 arcseconds. Some instruments (e.g. see Gaia, below), can do considerably better than that.
---
You will note that the relevant angle to Polaris is 0.0146 arcseconds, according to your own calculation. This is on the borderline for measurement with earth-based telescopes, but certainly well within the capacity of space telescopes to measure.
Thanks, Kermos, for confirming for yourself that the distance to Polaris can be measured with current technology, using the parallax method!
Kermos:
No, I don't believe that.
Let me tell you the actual history, since it seems you're unaware of the relevant historical events.
Leavitt identified 1777 variable stars, including 25 Cepheids, in the Small Magellanic Cloud, using photographic plates that imaged the cloud.
She assumed that all SMC Cepheids were at essentially the same distance from Earth. Therefore, any differences in their apparent magnitudes in SMC photographs must reflect differences in their absolute magnitudes. She was able to determine the gradient of the period-luminosity relation for the Cepheids in the LMC, but not the absolute luminosity scale.
She personally never measured a single Cepheid distance. However, two other astronomers calibrated Leavitt's relation:
1. Hertzsprung (1913) identified galactic Cepheids in open clusters. He used main-sequence fitting to estimate the distances to the clusters and then used those distances for the Cepheids (because the Cepheids were in the clusters and therefore at approximately the same distance as everything else in the cluster). This gave the first zero-point calibration of Leavitt's period-luminosity relation.
2. Shapley (1918) expanded on Hertzsprung's work by using more cluster Cepheids. He applied the calibrated Leavitt relation to estimate distances to globular clusters, which led to his finding of the very large size of the Milky Way galaxy.
Leavitt's work was fundamental in that it provided a standard candle with a predictable luminosity. This allowed astronomers to measure distances far larger than the parallax method permits. These measurements, in turn, set the stage for Hubble's discovery of the expansion of the universe.

To bring things more up to date, I also mention that the Gaia space observatory (ESA) was launched in 2013 and operated at the Sun-Earth L2 Lagrange point until 2025. During its decade of observations, it measured the largest, most precise 3D map of the Milky Way ever made. It scanned the entire sky, observing each individual target about 70 times over the duration of its mission. It observed objects down to magnitude 20, which is roughly 400,000 times fainter than the naked eye can see. It measured the positions of stars, their distances (using parallax), their proper motions, their brightness and colour and - in many cases - their radial velocities.
Gaia built a 3D map of between 1 and 2 billion stars. From its data, the absolute luminosities, temperatures and chemical compositions of each of those stars were determined.
Gaia achieved a positional accuracy of about 0.000024 arcseconds - equivalent to measuring the width of a human hair accurately at a distance of 1000 km. It's data set has been the top source for scientific papers in astronomy for years. Arguably, it is the most scientifically productive space mission in history.
Regarding Cepheids, Gaia measured the parallaxes of hundreds of stars in many separate open clusters. This data is used to calibrate the Leavitt period-luminosity relation.
Kermos:
Are you saying you're going to continue to tell lies for your God? Okay. That's entirely up to you. We'll see how that goes for you.
That's a lie, Kermos. Or is it a delusion? Your Lord Jesus didn't impart anything to you.
Do you hear voices in your head, Kermos?
You have provided nothing that refutes stellar redshift. In fact, all indications so far are that you don't know what a spectrum is or how red-shift is measured, or what it can tell us.
Your insistence on remaining woefully ignorant of what science is and how it is done is not doing you any favours in this conversation, Kermos.
Try harder, if you can.
Kermos:
The following few replies relate to your posts #971 onwards (excepting the ones I already addressed, above).
Again, I'm going to just skip over all your useless repetition. I won't be doubling up on my debunkings of your stuff that I have already previously debunked several times. And I'm going to keep ignoring your religious nonsense, too; your religious delusions are a topic for a different thread.
That suggests to me that Burbidge et al. were being scientifically honest, unlike you.
Do you admire Burbidge, Kermos? I suggest that he could be a good role model for you, if you want to change your ways and learn how a real scientist goes about doing things with integrity.
Pff! I learned the C language operators as a young kid. If you want a tutorial from me to teach you the C language, then ... forget it. I'm already too bored to waste even more time on you.
Chandra is an X-ray space observatory launched in 1999 on the space shuttle. Incidentally, it has an angular resolution of about 0.5 arcseconds.
The name "Chandra" was chosen to honor Indian-American astrophysicist Subrahmanyan Chandrasekhar, who won the Nobel prize for Physics in 1983 for his work on stellar structure and evolution.
The observatory has nothing to do with any religion. It is a scientific instrument.
True. But I gave you enough information to allow you to find more recent studies, if you're honest and sufficiently motivated to do so. I don't think for a moment that you'll put any effort into that, of course, because you're clearly a dishonest hack who is willing to tell lies for his religious sect.
(continued...)
The Doppler effect for light is a well-documented effect. I have even personally observed it at work in the lab.
Your silly denial that it occurs really is quite ludicrous. Do you expect me to continue to take you seriously, when you continue to clown around like this? Might as well get yourself a big red nose and some giant yellow boots, Kermos.
Kermos:
You're going to start being rational now? Oh, goody! About time.
That was the point.
Why would you want to calculate an average of those four measurements? Or three of them?
Both include 2.7255 K in the range of values, notice. Like I said.
Yes. So why would you want to average them?
Okay. But both measurements are consistent with T=2.7255 K. Like I said.
What's your point?
Er... what?Where did you learn statistics?Did you learn statistics?
Time goes forwards, not backwards, Kermos. I don't know what your silly claim about the "CMBR decreasing" is supposed to be about.
Want to try again?
I don't think I mentioned averages. You did.
Why would you want to use the mean, there, when the mean does not necessarily represent the temperature accurately, as both McKellar and Penzias/Wilson noted?
They do not. Your statistics teacher - if you had one - ought to be caned for teaching you so poorly. Well, maybe it wasn't his fault. Some students just never get statistics. Maybe you're one of those.
Or maybe you never studied it in the first place.
I accurately reported the data and the conclusions one might legitimately draw from it.
Context, Kermos. Context. You and I have been talking about the years between McKellar's result (1941) and Penzias and Wilson (1965) - possibly through to the present (2026), if you're honest enough to accept the most recent data.
That's a span of either 24 years, or 85 years. Compared to the age of the universe - 13.8 billion years - that's a negligible period of time.
Try to keep up, if you can. There's a good chap. I can wait for you to catch up.
Yes it is. Both measurements include temperatures between 2.5 K and 3.4 K. More specifically, both measurements include a temperature of 2.7255 K, which is the accepted modern value.
Well, that's a sudden change of heart, from you.
Did you change your mind mid-post?
Are you suggesting that older measurements might not be as trustworthy as newer ones? If so, I entirely agree with you. Well spotted, Kermos! You're making some progress, at least, even if it is very slow.
Sure I can. All the evidence supports the big bang theory, after all. Higher temperatures in the past are a prediction of the theory.
Meanwhile, you have still been entirely unable to account for the existence of the CMBR, let along its observed temperature.
How's that project of yours coming along, Kermos? Maybe you need to ask your Lord Jesus for some better help than he has been giving you so far. You're doing so very poorly. I almost feel sorry for you, wallowing in your ignorance over there.
