Yes but humans are experts at making up and posting mis/dis-information. Trying to convince the world at large (inc 'experts') just 30 years ago that our star is not the only star with planets around it was an impossible task.

I don't think we'd have anything at all to worry about from then on ;)

I think air born explosions cause a larger area of devastation, it's why atom bombs are designed to go off at a certain height rather than allowed to hit the ground I think. https://www.jpl.nasa.gov/news/twenty-years-of-tracking-near-earth-objects

This is apparently what would happen if a 1.5kM asteroid would hit the little UK island at 38000 mph (apparently happens once every 2.2 million years) .. https://neal.fun/asteroid-launcher/ https://neal.fun/asteroid-launcher

If it's the same as the 6SE mount then it will use a cheap chinese plastic toy gearbox that sits between the brushed motor and those output metal gears. We stripped down these plastic gearboxes to see how well made they were due to the high level of backlash on these celestron mounts. The plastic gears in these toy gearboxes don't mesh properly, so much looseness/backlash in them, it's terrible that they are using them on a telescope mount. What the Nexstar SE mounts need is someone to manufacture a replacement metal geared gearbox ensuring that the internal gears actually mesh properly. But whether or not you also have backlash in those external metal gears you've imaged I'm not sure of, the ones in our SE mount are fine, it's the plastic toy gearbox that drive those metal gears that is the real problem with ours

Real books as well ! :)

I don't find the only certain thing in life (death) scary, the thing I find scary is something like being paralysed from the neck down for the rest of ones life or such like. But anyway, going by past extinction hits to the Earth, it is a certainty to happen again, and again, and again. I just hope it hits where I'm located at the time. However, the next extinction event is now pretty much known, the only thing that will stop it now is if we ourselves decide to wake up, or not. It's not looking good though.

Our science isn't saying we're at the center of the entire universe, it's saying we're at the center of the observable universe - the only part of the universe we can ever see/detect (due to it's limited so far life time and expansion rate), hence 13.8 billion light years in all directions. The light from further away objects (beyond 13.8 light years) has not yet reached us, which simply means we can't see them (hence outside of the observable universe).

If you want a simple clean PSU without any hassle and are maybe not technically able (or just don't want too) to wire up things like step-up DC-DC regulators etc then something like these can be a nice alternative .. https://www.amazon.co.uk/Domfish-Portable-Generator-Adventure-Emergency/dp/B0B78J5VY3/ref=psdc_11714761_t3_B09PR8GR14?th=1 They have sine wave 230V outputs so fine for anything that wants a mains AC supply. I guess if you're willing to spend many 100's or a thousand or two on cameras and telescopes combined then an extra £250 on a portable silent generator is not a huge cost. They can be charged from the car/van or a portable solar panel if you like telescoping while on holidays or what not. If you want say a constant 14V DC (or maybe 19V for a laptop) from say a 3-cell lithium battery then the DC-DC boost convertor would do that for you, it would be a constant voltage supply up until the battery is drained. Something like one of these .. https://www.aliexpress.com/item/1005001336156816.html You'd also need a low battery warning sounder/indicator as well though so as not to over discharge a lithium battery.

I don't know if it was the problem that caused the failure or not but on the sensor bars they were showing the last we saw was the 2nd stage O2 tank level was at zero percent but the fuel tank was still at nearly 50% - they should be the same throughout the burn.

Zog'ist !

I'm not sure you can, I guess it depends on the application/data. Say you have a star that lights up a single pixel without effecting the surrounding pixels in any way, it's impossible to determine the exact position of the star within that pixel. Although when you start image stacking/super-resolutioning, you can start to exact it's exact position due to each image being ever so slightly different (due to telescope/atmosphere wobble) and so each separate image contains a little more of the missing jigsaw puzzle.

It's a paradox that the universe exists at all (whatever it may be). Where did the universe come from, it must have been 'something' (cause and effect). but then where did that 'something' come from, so on and so forth. Nothing comes from nothing, so how did anything get started in the first place Paradoxes indicate a fault with our thought process/method

Best not to confuse fact with fiction though ;)

We've been writing/creating simulated neural networks here (so called A.I) for at least 30 years now. Whoever put the 'I' into 'A.I' made a huge mistake, they either have no idea of what simulated neural networks really are, or they added the 'I' to somehow profit from whatever they were producing. Computers have no intelligence what so ever, they are nothing but extremely basic number crunchers, a simulated neuron is nothing but a simple addition / multiplication to output a single number (usually between 0.0 to +1.0 or -1.0 to +1.0. It currently takes a minimum of 1000 simulated neurons to get anywhere near to copying a bio-neuron does in just one aspect alone (input/output signal). Current A.I takes into account nothing of what a bio-neuron really does, we really don't know what the capabilities of bio-neurons are, nor can we ever know, they are so much more complicated than we ever thought possible. How atoms have come together to create such a thing is beyond us. Simulated neural networks are nothing more than a bit of fuzzy logic, there is no 'intelligence' involved at all, they only ever output what they've been taught to output (and can sometimes fill in some gaps), which is actually quite bad because anyone can get them to output anything they like .. hence the public should never see them as having any kind of intelligence or to have any real trust in what they throw out. Saying that, they are actually quite good at some pattern recognition tasks, you just have to remind yourself that 'intelligence' is something they do not have.

Heated gloves might be useable ? ie, https://www.amazon.co.uk/ObboMed-MH-1005-Infrared-Warming-Touchscreen/dp/B078K9FNH5

That's one of the best solutions for sure. For anyone who's not sure about network comms between buildings you can also use a mains powerline ethernet pair if they have a mains supply to there out building, although it might make the local radio hams a little angry if the mains wire run is above ground (they emit a lot of HF nasties).

Also, metal sheds make for very nice faraday cages .. could be good, could be not so good. If you have any wireless comms between shed/house etc using antennas inside the shed then communication could be severely restricted. if it becomes a problem then just mount say any wifi antennas on the outside of the shed.

I guess water/frost could have formed on the internal PCB(s), that would cause all sorts of problems with the electronics. Take a look at the boards, make sure they are dry/clean, and maybe brush (tooth brush etc) them over with 99% isopropyl alcohol.

There is a huge and inescapable problem with "UFO's" entering our atmosphere, NASA knows full well why they could never do such a thing, at least any biological form of aliens/crafts. The problem is pathogens, you could never mix life forms from different biospheres without wiping out either/both sides. A single virus or bacteria being passed from alien/craft to earth's atmosphere could cause all life on earth to be destroyed (due to earth life having zero resistance to an alien pathogen). Columbus had the same problem, they caused a lot of death in the tribes they visited due to passing on things like the common cold, the victims had no resistance to the 'developed' world's pathogens. Any alien life forms capable of moving from solar system to solar system would of cause know all this, the trouble is most human life forms don't

Yes indeed @saac, we can do nothing else, we have no other options unfortunately, we can but do our best. An awful lot of people out there are totally under the impression that our science is based on fact, when in fact we have no facts to base it on, we can only base our theories on our interpretations of what we think we're seeing. It's just that it's good to try and get that over to the masses from time to time. It's like various colours that we see, pink being one of them that actually doesn't exist, it's not a single frequency, it's an imaginary colour created by our minds eye. As you say, we're doing our best, which we should certainly continue to do. The real problem now though is the harm we're doing along side our need to learn.

Our physics is always wrong, it can only ever be based on our current way of thinking about the universe and our current state of observational abilities and limited thinking and imagination abilities etc etc. Throughout our entire history our race has always said it's worked it all out, or at least worked a big part of it out, when in actual fact we're most likely further from the truth than we can ever imagine. Examples are when they were certain the Earth was the centre of the universe/solar system, or questions about it's shape etc etc, the list is endless. A good scientist must never forget that it's we who are creating our models of the universe, we are being given no clues about any of it (at least not that we know of), the models will always be totally based on our view point and on how we interpret what we observe of our fumbling's around.

I guess hunger is there to try and force us to keep living, ie, stop eating and you'll end up suffering either/and physically/mentally. I guess love is there to get us to procreate/make more copies of our selves in order to continue living. How we perceive and experience those feelings I guess is yet again viewer based. Basically we haven't the foggiest idea what on earth is really going on here no matter how much we tell ourselves we know it all (or not as the case really is), our 'science' I suppose helps to reassure us in times of need (make life less painful etc), but also to satisfy our enormous level of curiosity and need to know of what ever is really going on here

Yes it is a good piece of software, until that is they decide to remove your access (they don't warn you) ! Just make sure that every design you do in it you export to your own PC on it's own SSD/HDD in a format that can be imported into other CAD software. IF you don't do that, you'll loose all access to everything you've ever done when the time comes.

The trouble with fusion 360 is that it's partly 'cloud' based, which means you MUST allow to access the internet every now and then at least. Autodesk is moving to this 'cloud' based method of operating, which means you're totally at their mercy. I used to use fusion 360 until they decided to stop me (along with many others) about a year ago or so for no reason at all. They've recently tried to get me to go back to using it (the paid subscription version) but I told them that I would never use ANY cloud based software again after learning of what they are really getting up to. This emerging 'cloud' system is something everyone should be extremely cautious about, you'd be very wise indeed never to allow yourself to become dependant on ANY cloud base software. Giving the public free access draws people in, then once they believe you've become dependant upon it, they'll pounce. Watch yourselves !
