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.

    • i just love this channel it teaches me more than school! for example; FRIEND: what'cha been working on lately? MY: oh not much just microbiome, immune system(dendritic cell, netrifiles, macrophages, helper t cells and way more), phages, stellar stuff, and way more want to know? FRIEND: uhhh... i think im fine for now!

    • Wait if you focus all the energy onto only one spot on the surface of the sun, wouldn't it get less dense as it superheats, Destroying the machine as it expands? Also, what happens if a solar storm breaks the dyson sphere and/or stellar engine?

  • Someone needs to create the Kurzgesagt game. You start in like 0500, at a day every 20 second, and speed keeps increasing to a week per second (2000), years per second (10000) and then on until things are happening on the scale of moving the sun in 30 minutes.

  • So if we moved the solar system with a stellar engine and otherwise, wouldn’t the rate we’d be moving at kind of throw off the planets if we were moving too fast for the pull? Or would we be moving slow enough that it wouldn’t?

    • the gravity of the sun is extremely strong, i think the only way to get a plant out of orbit is for another star/planet to sort of slingshot it away, if that makes sense

  • Sounds nice and all. But if lets say a Supernova just happened and is on its way to our solar System, we wouldnt notice it until it has arrived in our solar system. Just like we wouldnt know if our Sun disapeared up until 8 Minutes later. So nice Ideas but how should we even notice it before its basicly over?

  • If refocusing most of the Sun’s light back to itself using one of those mirror stellar engines in the shape of a half sphere, why wouldn’t refocusing a lot of the Sun’s energy onto one single spot and then have that energy converted into a beam that would shoot back at the same spot be dangerous? I mean it is just one spot, but it’s a lot of photons and stuff focused on one single point rather than all of the photons focused on the entire sun. It’s like laying on a bed of nails vs. stepping on a single nail. The bed of nails will probably be fine, but a single nail can do a lot more harm.
