I had a pet cricket named Chirpy. It started as a 5-gallon terrarium with a bunch of wolf spiders. I fed them crickets from the store, but then one big cricket outlived them all and lived for a long time. I'd take a chirpy pet cricket with his box, especially if the other choice was a dimwitted silent tilapia with his huge messy tank.

HOTH because of the cool clips. Questions: Do planetary ring systems always form along the equatorial plane? On gas giants with cloud bands, are these bands always parallel to the equator?
@IDoNotLikeHandlesOnYT
@IDoNotLikeHandlesOnYT Жыл бұрын
Rings: Some rings may be the result of moons that were disrupted by the planet's gravity or moons spewing material out (like Enceladus and Io do), and not all moons orbit in or near their planet's equatorial plane (particularly if, like Triton, they were captured by the planet rather than formed in place), so inclined rings might be possible. I wouldn't expect them to be as stable that way, though-they might get spread out more quickly by the gravity of other moons, for example. Cloud bands: Because they're caused by the planet's rotation, I don't see how they could be any way but parallel to the equator, unless the planet rotates so slowly that the atmosphere doesn't feel the rotation (but then there would have to be something else to make the clouds form parallel bands like that).

I’m grappling with this question Actually our solar system is a giant ring system around our Sun and all the planets formed within this ring system Our solar system is actually made from the left over debris that didn’t form to make our Sun Gravity pulled everything together from a giant gas cloud At the core of this cloud where gravity is strongest the Sun formed and the left over stuff formed into planets and moons an asteroids and all other material Some of this is still theoretical but they can witness this process unfolding in other nebula This is the reason astronomers are so interested in viewing what’s happening within these stellar nurseries There’s disks or ring system that form around new born stars They seem to form around the equator of the companion star but I’m not a rocket scientist and can explain this process from my own readings of this process Believe it has something to do with angular momentum and spin What’s amazing is there’s a second solar system around our Sun at a 30 degree angle to the initial solar system And it’s believed Planet X could be found in this other system or another theory there is no Planet X but a whole bunch of undiscovered worlds out past the Ourt spelling Think the second theory is more plausible Not really sure a lot of science began as speculation or theory Just saying I’m not completely sure about all I said If you agree that’s great Thanks for your time just trying to give my own answer to your question about ring formation 😅

Given the densities we work in venus I wonder why we never hear of such concepts like a boat. You figure, a Large, hemisphere with a little bit of water at the bottom for stability should allow such a platform to float as density gradient on venus can get rather large. Curious exactly how large it should entail but sounds plausible. Buoyancy is a function of displacement so large enough should create a boat that rides on the cloudtop with zero energy or mass input like leaking helium. Our minds might initially go against the idea of solids floating on gasses but its not without precedence as we do it with I believe sulfur hexafloride as a science demo here on earth.

A spaceship not necessarily made out of ice but a spaceship made in the traditional way but with a void along the entire structure's frame where you can pump in water (On orbit) where it would freeze providing protective shielding between the outer, iner layers of the spaceship. For an example like one of those thermos cups with liquid in between the drinking vessel and outer shell.

I have sort of three questions, all related to the 'frame rate' of our space observations. Feel free to combine them or just take individual questions if only one seems interesting. I know most modern observatories work by taking a series of images over time, not literally someone putting their eye up to an eyepiece, and that usually, the image are stacked on top of each other to create a final image. What is the 'frame rate', if you will, of some of the big well known telescopes? In other words, how much time goes by between individual images in the stack? And to ask the other side of that question, what are the most powerful observatories that can still capture something like video? And while it makes a lot of sense to me intuitively that in deep space things usually happen very slowly because of large distances between objects bright enough to observe, how well tested is that intuition?

I think legs on the booster will happen after they see how bad the damage is when a booster or starship slams down and explodes like a vacuum bomb. Temporary legs why not? Need them eventually anyways. I think this is a mistake. The legs are heavy but they help insure timely success and protect valuable ground assets like tank farms. RUD on launch becomes the only risk to major infrastructures.

BESPIN, because I feel it was NOT well answered. Your answer raised more Follow-Up Question for me: From my understanding it would make a difference at what angle an object approaches a black hole, wouldn´t it? If the object (Rogue planet or whatever...) is on a tangential trajectory close to its ecliptic it would end up in the accretion disk, pulled into an orbit and torn apart by the extreme gravity. I understand that. But what, if the original trajectory is aimed dead center at the point of singularity or at a point within the event horizon? Or if it approaches the "North/South Pole" of the black hole. Wouldn´t that be a straight swallow-up? What about an object, that hits the accretion disk from above or below? I imagine mud hits the fan-type effects? Wouldn´t the 2D accretion disk turn into an 3D accretion ball? Love your content!

if the rogue planet was moving at relativistic speed (10% the speed of light - and these do exist) ... depending on its mass wouldn't it just maybe partially get torn apart, but most of it would just pass through? My related question would be - what if a planet sized object moving at relativistic speed hit a black hole head-on ... would the time dilation near the event horizon basically just cause it to spaghettify into the accretion disk because time slows down so much at that point (in other words - nothing can pierce the event horizon "period" without going through the accretion disk first.

Question: considering E=MC2, and assuming there is a boson that carries the gravity force or something that works similarly to create that force… is it possible that a black hole is converting the fermions on fatter into bosons? Seems one could stack as many bosons as one you want without need space? Perhaps as this conversion happens as matter enters the event horizon and the resulting excess energy creates the GRBs we see only when black holes are eating? Thank you the shows are amazing! 🎃

Where is it habitable in the solar system? Well, depending on what you mean by habitable, every square inch of the solar system out to the Oort cloud and beyond would be habitable. All it would take would be a little bit of research into advanced materials, heating/cooling systems, and logistics. I might be understating the "little bit" part a tad, but whatever. Also: If I was chosen to go to Mars and be the first one to touch down on the planet, the first thing I would say would be, "Mission control, I've a feeling we're not in Kansas anymore, over."

So I have a few questions but I will start with this one, and it may sound stupid but it makes sense to me. Let's say that we were to be able to design a flashlight that can easily be shined upon, and seen on the surface of the moon. If we did so, would we see the light hitting the moon at the speed of light, or at half the speed of light? Half the speed being that the light would hit the surface, but would have to reflect back at the same speed to our eyes. Now obviously the time discrepancy is very small when speeking on the speed of light on an object as close as our moon, but the question still applies.
@frasercain
@frasercain Жыл бұрын
If you turned on the flashlight, you'd see the light on the Moon 2.6 seconds after. The light takes 1.3 seconds to get to the Moon, and then 1.3 seconds to reflect off it and come back to your eyes.

Aren't comets essentially icebergs in space? Maybe drill out living quarters inside one and attach rocket engines on it etc.

I oppose Starship because it is too complex and fragile; a lot could go wrong with it. Remember the Space Shuttle of which 2 out of 135 flights were disasters. Would Starship have the same rate of catastrophic failures? How would that impact the public perception if a hundred people were to die? In its place, I would have Sea Dragon, an old 1960s design for a huge, reusable ship with a 550 ton payload. It is an extremely simple design. The simpler something is the more reliable it becomes. It would be launched from sea, thus avoiding the destruction of a launch pad.

Hi, I guessed my question was too simplistic, Ive been hearing about asteroids coming near Earth, 2 in the last couple of days, we had a short heavy storm with torrential rain the first day, and it was very dark this morning, one was suppost to come between the Earth and moon would an Asteroid affect our weather, the asteroids had numbers that I cant remember, Im 74.

I've been saying for years that crickets are the protein of the future. They are quite common as a food in Mexico, I've seen them mixed in with guacamole and as a pizza toping. I've tried them and they're... meh. Given a choice I'll take steak every time, but on Mars you're not going to get that option. I can also see beef becoming too expensive for the average person to afford to the point where crickets make more sense.

Kamino Instead of raising crickets we'll probably be growing mushrooms and then if the technology has advanced enough, maybe texturized cloned tissue 🥩🍗. Could you imagine what would happen if the crickets broke containment? They'd get everywhere and in everything that wasn't hermetically sealed.

Mushrooms have barely any calories. I would prefer RockawayCCW's woodchucks or chickens. Something will have to be done with the skeleton and flesh that is not eaten.

Kamino I disagree with your proposal that crickets would be used as protein source though since there are many protein rich plants available and I'd eat beans and legumes 24/7 before a cricket ever gets close to my mouth. Now, if we found a planet that has fish, I'd use the crickets as bait.
