Nothing in the Universe is static. In the milky way, billions of stars orbit the galactic center.
Some, like our sun, are pretty consistent, keeping a distance of around 30,000 light years from the galactic center, completing an orbit every 230 million years.
This dance is not an orderly ballet - more like a skating rink filled with drunk toddlers. This chaos makes the galaxy dangerous. Our solar neighbourhood is constantly changing, with stars moving hundreds of kilometers every second.
Only the vast distances between objects protect us from the dangers out there. But we might get unlucky in the future. At some point we could encounter a star going supernova. Or a massive object passing by and showering earth with asteroids.
If something like this were to happen we would likely know thousands, if not millions of years in advance. But we still couldn’t do much about it.
Unless… we move our whole solar system out of the way.

Our species can't even figure out underground sewerage. People seriously think humans won't be extinct with 200 years are mistaken. The time for humans to go extinct because of our arrogance is long overdue. We dump plastic into the ocean, we melt polar ice caps, we destroy the ozone layer, and you idiots seriously think we're ever going to do any of this?!

Would the Caplan Thruster really extend the Sun's lifespan? Lower-mass stars certainly live longer than higher-mass stars, but the Caplan Thruster's method of harvesting fusion material from the Sun's surface/outer layer would make no difference to the hydrogen content of the core, where stellar fusion actually occurs. (Please correct me if I'm wrong)

What are you guys talking about. If you really have to dodge a supernova then why not build a powerful and intelligent sphere or a shield alot closer to the earth which can be assembled and dismantled as per the requirements. That sphere or shield would not only protect the earth from an anticipated supernova but can also act as a giant solar panel to harness the sun's energy and direct it towards earth at times when it shades us. This obviously is difficult but not at all as difficult as building a giant engine or a sphere around the sun with a million year program to move the whole solar system out of its galactic orbit. This type of sphere around the earth wouldnt need immense temperature resistance materials that you would need closer to the sun. This will not have to be as big and will also be alot less expensive.
mhC Пре дан
@Squidge Lad Supernova will hit the earth from a single direction. The shield may have to only protect us from that part of the space. The shield will not cover the whole of earth but will move accordingly just to protect us from that deadly supernova beam. The technology at that time will anticipate exactly where the beam will hit with lets say + - 100 % design factor. It will be in space so it will either be in orbit and / or will be held up by earth"s gravity like the moon is held up.That shield can also act as a giant efficient solar panel to harness sun's energy and direct it towards the shaded parts. Anyhow the technological revolution we are discussing, in those times iam sure mankind will have devised a way to supply energy to the temporary shaded parts by nuclear or some other way.

@Dinosaurus Rex maybe, or maybe you could do it on every star or enough stars and it might drag the black hole with it? Or actually!!! if the black hole couldn't be pushed then you could have the caplan thruster but with only the part firing into the black hole. this way the black hole is attracted to the thruster but the thruster keeps pushing away? maybe not but who knows?

There is a lot of iron in mars, why doesn't NASA want to take the irons? Mars is rich in iron, then we can still use that when making a fast engine

Because, 1. Chances are they wont use iron for making a thruster 2. Mars is far away and hard to get to 3. It is hard to get energy on mars 4. Mars is further away from the sun
