Technology, Science & Alt Science / Arianespace Vega launch failure
« on: November 17, 2020, 05:38:34 PM »
https://spaceflightnow.com/2020/11/17/arianespace-traces-cause-of-vega-launch-failure-to-human-error/

Sad to see those satellites get blowed up, but I had to shake my head at this part.

Engineers concluded that cables leading to thrust vector control actuators on the upper stage were inverted, apparently a mistake from the assembly of the upper stage engine, according to Roland Lagier, Arianespace’s chief technical officer.

The cabling problem caused the engine to move its nozzle in the wrong direction in response to commands from the rocket’s guidance system.

Lagier characterized the inverted cables as a “human error,” and not a design problem.


Using a non-keyed connector in something as important as the signals to control motors in a rocket is absolutely a design problem.

Human error caused it, but the design allowed that mistake to be made in the first place. Doh.

Arts & Entertainment / Tom Cruise unites Round and Flat Earthers!

Tom Cruse has been cleared to visit the International Space Station to film a movie.

Do you know what this means?

Once he's on board it won't matter if you think the ISS is a soundstage in California or orbiting the Earth...

...we can all agree that the ISS is a technically Hollywood set.

I'm so excited.  ;D

Technology, Science & Alt Science / New Jupiter Photo by NASA

A majestic gas giant or just NASA projecting it onto the dome, it's amazingly beautiful either way.

Technology, Science & Alt Science / Photon Satelite

One more private company to put their own satellites into orbit.

You can buy launches to Venus too, I wonder how much that costs.

Venus needs more love, it's such a crazy planet. Maybe I should start a crowdfunding campaign to drop a GoPro on a a parachute to see how long it lasts before the acid and heat destroys it. Think that would void the warranty? :)

Arts & Entertainment / Sunlit Clouds
« on: August 26, 2020, 05:10:56 PM »
Thought I'd post some art in the art forum.

Doesn't matter if the sun is below the clouds on a round earth or bendy light on a flat one or any other explanation, it's an awe inspiring photo that everyone can enjoy.

Plus it's from Austrailia.

The dictionary definition of is "alert to injustice in society, especially racism." - and where it maybe an annoying trait to describe yourself as such, or ask if someone else is, I don't understand why nailing an animal to a door is "woke"?

Are you sure it is?

That's the original AAVE meaning of it, but it has since been stolen by middle class white weirdos.

Example - Teen Vogue published an how to have anal sex article, one of their Twitter interns tweeted "I'M THE WOKEST" after parents objected to teaching teenage girls how to take it up the ass.

That is indeed the problem with labels, and why we shouldn't say "That article is a bunch of Woke nonsense" but say "That article is a bunch of nonsense."

It just helps them steal the name.

On the other hand... any couple who had the unpleasant experience of trying anal sex without having any idea what they were doing probably would appreciate some tips first. :)

Flat Earth Debate / What are comets?
« on: July 14, 2020, 08:09:56 AM »
I just took this picture of NEOWISE C/2020 F3 last night, I'm greatly looking forward to it getting brighter and finding a better spot with less light pollution in the next few weeks when it's at it's brightest.



Comets always have gas tails pointing away from the sun, due to the solar radiation blowing the melting ice away.

How does Flat Earth Theory explain these?  Especially with the crazy retrograde orbits many have, like NEOWISE shown below.  Science and astronomers already had this prediction for it's path for months, and I've verified it by taking a picture last night, it was exactly where it was predicted to be. I even saw it directly. It's faint, but visible.

The Lounge / Am I Myself?
« on: June 30, 2020, 11:24:38 AM »
Hey JackBlack, I wanted to say hello since we haven't been formally introduced.

I also wanted to ask, are you me? If not, how can I be sure?

Because I saw this below, and that's pretty good evidence! I'm not sure how to counter it, and after reading your posts you seem like you know how to argue logically, so you were my obvious choice for help. And I need it because as you can see, it's posted right on the internet.



Anyone else who isn't sure if they are also someone else is free to post here and ask, and I'll do my honest best to help. It's confusing!

https://www.nasa.gov/feature/goddard/2020/watch-a-10-year-time-lapse-of-sun-from-nasa-s-sdo

I wish they would have filled in the missing frames, the blinking is a bit distracting but I guess they were worried they would get accused of doctoring the video.   ::)

But it's an amazing video.  Fascinating to watch the sun hit it's solar maximum with all the activity and then quiet back down.  I'm looking forward to the next cycle so I can get more sunspot pictures, hopefully with upgraded equipment by then.

Crazy to watch those flares spring up. 

You can even download HD videos of it.

Flat Earth Debate / How does Flat Earth Theory explain Leap Seconds?
« on: June 17, 2020, 08:48:36 AM »
https://en.wikipedia.org/wiki/Leap_second

It's been long observed that the length of the day has been gradually increasing over time.  As atomic clocks have gotten better, this slowdown has gotten easier to detect. It averages about 1 to 2 ms per century. It's a small amount, but has been measured with more and more accuracy as technology improves, and we now have a long record of continuous data to examine.

Conventional science explains this as the Moon's tidal forces slowing the spin down as the major cause.

Are there any Flat Earth theories that explain why the length of the day is gradually getting longer?

So I was looking for some other ways to measure the Earth's rotation, and I knew about ring gyros, but this one was new to me.

https://physicsworld.com/a/optical-gyroscope-on-a-chip-can-detect-earths-rotation/

Apparently Kerry Vahala and their team have made a gyro on a chip that is expected to eventually be ten to a hundred times more sensitive than a ring gyro.

The exciting aspect of this to me, is once they get it made, this ring gyro on a chip should be eventually very, very cheap. Cheap enough for anyoen to buy one to play with, even if not as cheap as the ones in out phones.

How crazy would it be to be able to spend $100 on something that can directly measure the Earths rotation with more sensitivity than anything we can build now?  I'd buy one right now if they were for sale.  No more need for $20,000 ring gyros once this makes it into production.

Flat Earth Debate / Re: Sun Spots
« on: June 05, 2020, 12:09:14 PM »
I keep forgetting there is one forum I'm not allowed to post in.  Moved here...

Stars rotate , not spin. You are constantly asking similar question with same missconception. Many observations reveal that the stars move in meaning of rotate but do not spin around their own axes. you can compare the spots on the sun with the spots on any camera.

The spots on the sun show us that there are things around earth whose do not like cleaning.

Stars most certainly do spin. The sun certainly does, we can see the fine structure of it now and easily watch it. Nothing about the below image is because of a "dirty dome" or other nonsense. If there was a dirty dome, we would see "sunspots" on the Moon too. Or in the sky. Or nebula and other galaxies we can image.

No way a "dirty dome" is going to produce what is clearly a spinning sun. Stars spin.

I've also taken many pictures of sunspots with my own camera and telescope and can 100% state that it is not because of a dirty lens, and I certainly didn't use any CGI.

Flat Earth Debate / How to map the Earth?
« on: May 21, 2020, 11:50:22 AM »
The lack of a single, accurate map has long been an issue with defending or debating the Flat Earth theory.

What I would like is to hear some ideas on how this could be done. It doesn't matter if the idea is too expensive or requires too many people or access to military equipment, I'd like to hear any and all ideas. Clearly it has to be possible to make a map of the entire surface, we know cities stay in the same place year after year so it's not like trying to hit a moving target.

So what are some good ideas? If Bill gates gave you ten billion dollars, how would you use that to do it? Or how would you use all the members here spread all over the world. We have the Internet and all kinds of technology, computing power and resources the wealthiest scientist would be envious of 200 years ago at our disposal.

What will we do with it?
