RE: I ASKED SCIENTISTS WHAT ABOUT OUR EXTINCTION LIKE DINOSAURS? AND THEY REPLIED WE HAVE STELLAR ENGINES

Hi @leonardodaslade thank you for writing such a thoughtful article. @Kurzgesagt did a good job on their video too. But there's still a few things that I don't understand about the idea of moving the Sun.
Like, during the million years of travel, why wouldn't the planets end up trailing behind the Sun like the particles in a comet's tail (wouldn't their orbits deteriorate)? And then when the Sun arrives at its new destination and stops moving, wouldn't the planets crash into it? Maybe you could help me understand how gravity 'locks' the planets in place.
But also, if we could build a giant Dison Sphere around the Sun, then why not just build a smaller sphere around the Earth to protect us from asteroid showers?
If we could use electromagnetism to feed the Caplan thruster, then why not just use electromagnetism to redirect the solar winds? With the right 'shape' of electromagnetic field it may be possible to optimize acceleration by concentrating the solar winds. In fact, we might not even need a thruster, we could just drop the right combination and proportions of certain heavy elements into the Sun repeatedly to cause a propulsive reaction at just the right spot. Doing that could effectively turn the Sun into it's own thruster.
But like I said, I'd be worried about the planets losing their orbits during the million years of travel. (I think that every time the Sun's course and trajectory are altered, the planets and everything else effected by the Sun's gravity would experience an orbital reaction.)
We might even be able to create a small black hole and place it in a specific elliptical orbit around the Sun (much farther out than the planets, but just close enough to the solar system to pull a little bit on the Sun and planets every time it comes around the near-side of its orbit).
If humanity is technologically advanced enough when a problem arises such as a super nova or anything like that, then it may be more cost-effective (or simply human nature) for people to spread out among the stars, and maybe bring pieces of the Sun with us to keep burning like eternal flames.

@anomaly I am at your service for explanation. 😉
Okay so firstly you asked about gravity, so I would say that the planets will not go out of their orbits or either this would affect their orbits. All the planets and matter in our solar system are bonded to Sun through the force of gravity that Sun applies on every matter in our Solar system, Else try understanding Law of Gravitation by Newton too.


It states that:
Every body in the universe attracts the other body with a force that is proportional to product of their masses and inversely proportional to square of distance between them.


so, Sun is attracting us and we are also attracting it with the same force


Consider example of a magnet when you pull a metal object with the magnet it will attract it but if you pull your hand fast with a jerk then the object won't be attracted towards the magnet if magnet doesn't have much attraction. Now we are not going like f1 cars through our Galaxy, the process will be slow but fast as compared to other movements in solar system. So, as there would be no hurry, the planets will slowly move throughout the milky way with our Sun.


As you think of Dyson sphere, it can only be used to harvest energy from a star, it wasn't made for protecting a planet, the Dyson sphere will provide kind of more energy and will help to get the energy evenly to the thrusters , What will you do Don't you want other planets in our Solar system? every of them with its own properties. Well if you think to put Dyson sphere on all of them just think how much will it cause us.


Well Shkadov thruster was like moving the Sun without harvesting any energy but it limited our direction to move in the galaxy, I don't think electromagnetism can be used for redirecting the solar winds, they are maybe attracted towards the pole of Earth that's why they enter from the holes at the poles and maybe they made the holes🤔


Of course the Caplan thruster will affect our Sun but the real thing is that it is making our Sun younger, you know one day Sun is going to die but as Caplan thruster will harvest the energy from Sun causing its radiation levels to low down and this will make the Sun younger and will give it some extra life span. where would you bring elements from to feed Caplan? else it is making the Sun younger so its beneficial for our generation.


If we become intergalactic you know what will we do mine the other planets lol, our resources from the planets will like endless we may discover new elements to place them in our periodic table.


however, we aren't advanced at this time but maybe in future we may build the stellar engine.


I hope you have understood my explanation If not, come and talk with me on Discord: IRON MAN#9976

Thank you for your detailed explanation. And I'm sorry for arguing, maybe I'm still misunderstanding something.
I think we can both agree on this: "Every body in the universe attracts the other body with a force that is proportional to product of their masses and inversely proportional to square of distance between them."
It seems that we only disagree on how to interpret that. But I feel as though I need to ask: What do you believe would happen if you chose to move the Sun in a direction that would bring it closer to the Earth? If gravity attracts objects, then how would it repel the Earth away from the Sun's advance?
But either way, I think once the human race gets out there into space then we won't really need our home star for survival anymore. Maybe another question is how will we escape the Universe when time slows down in the big freeze?
