Yes it sure would be a privilege to witness. So far the icing for me was over 50 years ago when a a kid was on a camping holiday with my family. One clear and moonless night I was lying on my back and I spotted a comet with my acute childhood eyesight. I tried to point it out to my father but he couldn’t see it and couldn’t find it with hand held binoculars. Over the following months I tracked the comet as it made its way across the sky and then to my horror and disappointment it was announced that a new comet had been discovered by some amateur astronomer. I still feel ripped off as it should have been named after me.

@@mitseraffej5812 for me it began on a dark moonless night over sixty years ago as I watched a large meteor seemingly cross slowly from horizon to horizon, it’s incandescence bright and colorful. Not knowing what it was (assuming it was fireworks) I asked my dad and the neighbor who were not looking up, but chatting what it was, and they had time to witness it too. My dad answered “that’s a fireball”. By 1995 I had built a large reflector telescope so my kids could witness comet Swift-Tuttle. Life is good.

It occurs to me that the ancient myth of Orion being killed by the Scorpion would tie in nicely with a surge in brightness of Betelgeuse. I doubt that it's possible to know if that's where that myth came from, but it would be interesting if it was an ancient memory of a prehistorical surge in brightness.

Very good thought process of what time really is to humans. Maybe the Egyptians had it right all along and knew way more than what we now know. I am a firm believer in time travel, just that humanity has yet to understand the fundamentals and principals of harnessing the forces needed to make it safely possible. For example, where did the map of what Antarctica looked like before becoming just a snow and ice covered continent? Who was around that long ago to see what it actually looked like........

The reason that video of the landing Falcon 9 first stage appears to be so perfectly locked, is that this has been post-processed. A video is recorded that is not so perfectly tracking, and then a smaller section is cut out of this that is centered on the image of the rocket. So the result appears to track the rocket much better than it was in the original. You can see that when they zoom out at the landing, and a black bar appears at the top, revealing that they now don't have a recording of the part of the image that would have to be there. That issue would not occur on the raw video.

Interesting to see how many people really want to see Betelgeuse blow up, I have to confess to being one of them. But, losing Betelgeuse would also be quite a loss as it is one of the brighter and most identifiable of stars given its location around Orion and its distinctive red color. Still, what a show that would be, nothing in our lifetime or the life time of all humans going back hundreds of years at least will compare to the show it should be. I do hope that there is always at least one good telescope watching Betelgeuse at all times. I also hope all the gravitational wave observatories are in operation when she pops... Of course, it might not pop for a million years.

I sure hope Betelgeuse will go nova in my lifetime. That would be even better than watching Halley's comet. It will need to hurry though. lol. So Betelgeuse is my favorite story this time. As for power from space. One of the big advantages when the technology is developed enough would be that the power receivers on earth would receive power long before sunrise and long after sunset. That would drastically reduce the time that energy needs to be stored or generated in another way. (if I remember correctly, there are even some satellite constellations that could generate power close to 24/7)

In Bladerunner, when Roy Batty gives his iconic speech at the end, he says in part; "If you could see what Ive seen with these eyes. Attack ships on fire, off the shoulder of Orion." It was many years later that I realized that the shoulder of Orion is actually Betelgeuse (Alpha Orionis). Just putting that out there. Kinda wonder if those attack ship were on fire because of war, or Betelgeuse was throwing a fit and hitting them with unexpected solar flares about a thousand times more lethal than our sun. Becuase if you think about it, there couldnt be an offworld colony there. Betelgeuse is far too volatile.

It's probable that the main reason that Betelgeuse is behaving so weirdly is because of the mass ejection that caused it to dim in the first place. When that amount of material is ejected from a star there are going to be aftereffects, in this case large amounts of plasma sloshing around in the same way a bath sloshes around if you quickly pull a large bucket of water from it. In this case the effects on Betelgeuse would include shockwaves causing the core of the star to ring, and collisions between large amounts of plasma at very high speeds, the effects of which would lead to increased fusion and a brightening of the star.

*Solution to the "Time Light Problem"* The reason why people often stumble over the *assumption* that light years in outer space equals the same measure of distance and passage of time on earth is because general relativity is not being taken into account. In general relativity, the local rate of time and the measure of distance depend on the amount of matter or mass in the vicinity. Locally, the rate of time and measure of distance doesn't change much inside of our galaxy. However, the distance in our line of sight between us and distant galaxies is extreme and running at a much faster rate of time as well as an expanded measure of distance outside our galaxy compared to where we are near Sagittarius A's Milky Way black hole (where our rate of time is much slower and our measure of distance is much more contracted). The same way the earth appears flat locally, our universe also appears to be flat locally. However, over great distances throughout the universe there are differing measures of distance and differing rates of time from black holes to the lagrange points between black holes where there is very little acceleration compared to our relatively flat contracted local frames of reference near Sagittarius A. When we observe other galaxies, we are effectively looking at vastly differing measures of time and distance relative to our local observations within the gravitational force of the mass of the Milky Way galaxy. This can lead to various observed phenomena as we look into outer space such as redshift, superluminal motion and the apparent faster motion of the outer spiral arms of galaxies. It's not the same as our flat observations of cats and dogs locally here on earth where we don't observe differing measures of distance and time. So the supposed expansion of the universe, imaginary inflatons, invisible dark matter and dark energy or vacuum energy are *not* required to explain the observed redshift of light from distant galaxies or the faster than expected motion of the outer spiral arms of galaxies. As predicted by general relativity, the expanded space between galaxies due to the absence of matter in our line of sight where much less acceleration can explain the observed redshift without the need for a nonsensical universe expanding into oblivion for no apparent reason and it explains the faster than expected motion of structures and objects the farther it is from supermassive black holes. It turns out that the vacuum energy of space is due to the frame dragging of black holes that are growing from gobbling up spacetime regardless of the amount of matter being consumed. Recent findings of a team of scientists have found that dark energy or vacuum energy is associated with supermassive black holes that are all growing in size, as opposed to an ever expanding universe. It turns out that light is blue shifted going into a gravitational well so the converse is true of being redshifted traveling great distances outside of gravitational wells. Supermassive black holes are the most powerful forces in the universe with far reaching effects of gravity and vacuum energy. The problem and solution is that between galaxies, all of the galaxies all around are all together pulling and drawing in spacetime as well as exerting equal gravitational forces on empty space. This is the reason there is very little acceleration between galaxies and where there is expanded distance and a faster rate of time. The clocks are running faster outside of galaxies and the measuring sticks are larger meaning things are actually less distant than they appear. The more gravity drops off outside of the galaxy and in between galaxies, the more distance will be expanded and the faster the rate of time will be. As predicted by general relativity, the expanded space between galaxies due to the absence of matter in our line of sight where there is less acceleration explains the observed redshift without the need for a nonsensical universe expanding into oblivion for no apparent reason at all. The differing rates of time and differing measures of distance also explain *how* a day is the same as a thousand years and a thousand years is the same as a day, at the same time in the same universe. 13.8 billion years is the same as 6,000 years and 6,000 years is the same as 13.8 billion years *within the same created universe!*

About the perfect locked in view of Falcon 9 landing: several artifacts show that it's been digitally stabilized. First when the engine lights up, the rocket wobbles a bit. That means the view moved a bit and the shutter scan had an effect on the apparent size of the rocket. So it wobbled. Second, you can see the framing in top of the image when the rocket lands. That means the camera tracked too low. It was good, but it was not a perfect tracking.

The video of the Falcon 9 landing was a software stabilized video, if you noticed how the top of the frame moves down near the end.

Hi, very random question: How would one measure mass in microgravity - lets say on board the ISS? I.e. I would imagine it comes up in various experiments, and apart from a centrifuge and measuring the pull i couldn't really come up with a decent way. And the centrifuge way might not be the best choice for all scenarios, for example if we want to measure how much biomass we produced in some plant growth experiment, where the object can be somewhat large (plus the plant might not take it kindly).

What NASA could do regarding Starliner's electrical cabling and its flammable insulation is to paint all the cables with West System epoxy, the hardest and toughest epoxy in the universe (used for boats and canoes), and absolutely non-flammable. Far cheaper than having to redo the wiring, and far easier than to wrap anything around the cables; and probably far safer, as a wrapping would leave gaps, while a couple of coats of epoxy will probably not leave even a single point of exposed flammable material.

I know because when I've used it I often had a glassful of mixed liquid left-over, which solidified in the plastic cup or whatever I mixed it in, and then it hardened and I kept it as a souvenir, and it is definitely lighter than water. And thinking about this in comparative terms, the solution that NASA considered, of over-wrapping all the cables, THAT would definitely add more weight than a coat or two of this epoxy varnish. To get to a millimeter thickness, as used to bullet-proof those kayaks for navigating rocky rapids, for example, it takes about 10 coats of the stuff. This solution would be superior, in that a manual over-wrap would leave gaps, whereas painting with epoxy, specially a double-coat, would not leave even a point anywhere of exposed flammable material. Additionally, WS epoxy is the toughest in the world, famous for it, and so doing this would strengthen all the cabling against accelerations, vibration and whatnot. I left a message for NASA through their website Contact; I hope they read it and consider it. EDIT: Been looking for density info on West System epoxy, but can't find density data. However, suffice it to say that this epoxy does not "want" to be applied thickly; it "slowly runs", pardon the oxymoronic sound... This is counterintuitive because it is quite viscous, which one might incorrectly assume to imply something about surface tension ... West System epoxy has almost zero surface tension; it flows slowly but it flows steadily. If you paint it on top of a wooden surface with a thin crack, it will slowly but steadily penetrate the crack and start dripping from the underside. Painting cables with it, and trying to be "generous" with it, would probably result in the stuff dribbling down the cable to the lowest point and dripping from there; so it kind of forces you to apply it thinly for it to NOT do that.

To see it go supernova, we all need to say "Betelgeuse, Betelgeuse, Betelgeuse!" at the same moment. Maybe if we chew betel nuts and chant Betelgeuse?

there's a 2200 day cycle and 3 shorter period brightness cycles, so I would assume it's burning carbon to neon/Oxygen. if it's large enough to supernova it's got less than 10k years, if it's nearing the end of the carbon cycle it could be ~ 200 years to 20 years away from exploding. neon ~ 15 years. Oxygen ~ 6 years. Silicon ~ days. Iron ----> boom

As everything is cyclical the old universe collapsed and boom, the big bang happened but this may have happened in multiple places and different times across the universe. It would be silly to think there was only one big bang. It would be like thinking there was only one galaxy or one star system. This concept would allow for differences in our thoughts on distance and time.

What would be the best way to beam energy? Signal going through storms, rain, wind, snow. But it seems a network of geostationary satellites with highly-efficient transmission of energy whether laser, microwave, radio...should give a nice boost to global grids.

I'd also like to add that the JWST images of these earliest galaxies are beginning to show up on Galaxy Zoo for classification. If you're someone who likes astronomy and has some spare time, you might want to take a look. (For those who don't know what I'm talking about, Galaxy Zoo relies on citizen scientists to classify galaxies and point out anything of note. Occasionally you'll see something really spectacular.)

Hi Fraser, Firstly thank you for all your hardwork! Your podcast makes long distance driving much more enjoyable with something interesting to listen too! I’ve been wondering for a while, have we been thinking about terraforming all wrong. Shouldn’t we be focusing on “bio-forming” . So instead of trying to make a planet like earth, we make a dynamic ecosystem which is setup for organisms on that specific world. Such as creating a biosphere on Mars which creates its own magnetosphere via bio-magnetism. Is this all gobbledygook or actually feasible? Thanks, Ophir

I can't think of how an organism could generate a magnetic field that's equivalent to a 1000 km ball of spinning metal. But it could help produce an atmosphere that would help block the radiation.
