Physicist Reacts to THE EXPANSE is the Most Scientifically Accurate TV Show

Well, if you had a spacecraft with an engine at each end, and use the second engine to decelerate from mid-trip on, then inside your spaceship your ceilings become your new floors. It may end up being more economical to just flip the ship, rather than duplicate all the furniture.

Expanse loves youtubers and reactors. They literally named a bit character after Rana from "The Normies" confirmed from the director. The writers would have reaction channels on in the background in the writers room.

So when the show was cancelled in May 2018 during the airing of S3 it was actually the fans that banded together (in support of the actors ) to live stream the rest of the season, get the live viewing numbers up, and the fans flew a banner over Amazon headquarters after a fund raising effort worked in 24 hours. (#SaveTheExpanse banner). The fans also used a weather balloon to take a little Roci model into the upper atmosphere ("outer space!"). so yes the actors LOVE the show (see Ty and That Guy podcast running for over two years now) but it was the fans coming together to save the show which was crazy and incredible. We are the Screaming Firehawks.

how exactly would a second engine be more efficient than just rotate the spaceship? efficiency will always be important and the comfort of 1 less turn in space will never outweigh the cost another engine would have.

The "flip and burn" concept was not first conceived by the authors of The Expanse. I first read about it 1965 in the Robert Heinlein novel "Have Space Suit-Will Travel" that itself had been written in 1958. Heinlein was an engineer (with a Navy background) who had worked with early US space engineers of the day.

8:20 Actually, having engines both at the front and the stern of a spaceship doesn't makes sense in expanse at all.. You need to remember, that you actually get gravity from the engine thrust. So if you just would reverse thrust, suddenly all your stuff would be upside down.... Which might be ok for some cargo ... but i bet, even the hardest beltaloda wouldn't be able to stomach that for long.. ;)

The idea of fitting an engine on either end of a craft and not flipping over is a terrible idea simply because think of the orientation and direction of force inside the ship. By flipping the ship and only applying force from one end you can have the concept of a ceiling and a floor in the orientation and layout of the ship meaning that you can also have tables and countertops and ergonomics that are consistent with a planetary gravity type environment. If half the time the perceived force of gravity is coming from above you then how do you orient or layout things like chairs control panels, sleeping surfaces etc. Virtually every human interactive surface would need to be on some sort of gimble so it can reorient based on the direction of the force relative to the ship. By having one engine located at one end then you have a consistent concept of up and down when the engine applies force.

Pretty sure we got a cameo by Adam Savage. right before the wire stuff

The concept of sphere-shaped spaceships is not new. Most bigger ships of the Terranian Empire in the Perry Rhodan Universe are of this ship. It is stated that this would be the form which is most resistant to any forces from outside. They have a thruster belt around the meridian so they never have to rotate the ship more than 90°.

In the movie “Event Horizon” the ship Lewis & Clark has large thrusters at the front for rabid deceleration. Loved that detail.

An interesting thing I heard about a possible explanation (admittedly, almost certainly retroactive) for the sound in space and manoeuvring of spacecraft in Star Wars was it being set in a universe a luminiferous aether of some kind, mostly because of a few sci fi gadgets and parts including the word aether, like I think a ship is described as having an aetherium rudder and many other mentions of rudders in general

even if we never get the rest of the TV series, at least the books are complete. :D

Well isn’t with warp you’re moving space around you rather than the ship, so if you’re creating a warp bubble would you even feel the effects of speed? You should do a vid on that and how a Mexican physicist accidentally discovered a warp bubble.

It would be quite a stupid idea to have engines on both ends instead of just doing a flip&burn with the ship. First, it would be a waste of money, ressources, and the ship's interior space as there is really no need for this. Second, everything in the ship would have to be designed to be accessible from both sides, as the moment you change thrust to the "front" engine, the ceiling would become the floor and everything would be upside-down. That all really wouldn't make much sense as you can just turn around the ship instead, so the floor will always be the direction to the engine.

5:48 this happened at the end of August 2018. Just google The mystery of the hole in the Soyuz or use translate for more detailed articles in Russian. There were no casualties. 8:17 Firstly, it is much more expensive, secondly, two nuclear engines would emit twice as much radiation, and thirdly, on small ships it would take up space for weapons, so the option of turning the ship around is much more effective.Moreover, for turning, only shunting engines are used, which do not waste fuel intended for long-term acceleration.

I would say, of course there is speculation in terms of gravity effects on the body (because I don't think there is yet a colony on an asteroid or mars), but I think its a best guess situation based on current science which a lot of the show is in general. In 30/40 years we might think this is stupid! and I know nothing about physics! but to me it all makes sense! lol

you can have a sphere with a ring around it. the sphere can have a pipe around it with 6 holes and the ring covering it that has only has 2 holes so at any time, only two holes are open and 4 closed by the ring. each hole connected to engine and used as thrust exit. spining the ring would cover 4 holes and open other 2 depending in what direction you need thrust. easy :)

Do you know the show Planetes? It would be cool to know your opinion about the accuracy of at all.

Speaking of dreams, dreaming is actually highly underrated. Plus the more you know about a particular subject the more accurate your dreams are likely to be
