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.

Kurzgesagt – In a Nutshell
10 місяців tagasi
This was our last video for the year 12019 of the Human Era. And what a year it was. So much stuff happened everywhere. To so many different people. Calendars and holidays are just imaginary but they help us to cut our lives into pieces that our brains can handle. We are leaving 12019 behind with a weird mixture of disillusion and hope. The world is screwed up. But we can fix it. In a few days this year will be over. And we all get to try again. Thank you for watching our videos and for sticking around for so many years. See you all in 12020.

It is now October 22, 2020, and as we all know all too we'll, this Kurzgesagt posted at the end of last December will in fact NOT "see us ALL in 12020." We have learned all too well from what I prefer to call "the Communist Flu" (because it is that inflexible ideology and its dual lethal arrogances of experimenting a with deadly virus and botching the safe storage of same that got us here, not the fact that it happened in China) that added this year's global Covid-19 toll to the 100 million victims of Communism since 1917. We have also learned the limitations of science and medicine in predicting the best therapies and strategies to control and mitigate pandemic death, which I sincerely pray will humble us all at least slightly in the years to come.

Well, one think keeps bothering me with this concept. I understand that if we move the Sun, other planets etc. will "follow", but wouldn't that change the trajectories in which everything circles the Sun? Even if only slightly... with distances counting tens of LY, the the difference will be bigger and bigger, and couldn't this have some fatal consequences?

It's neither Two Thousand and Nineteen nor Two Thousand and Twenty. Its Twenty Nineteen and Twenty Twenty (2019 and 2020). Here's the pattern: Seventeen Hundred, Eighteen Hundred, Nineteen Hundred (1900), Twenty Hundred (2000), Twenty-one Hundred. Nineteen Hundred One, alt. Nineteen "O" One (1901), Nineteen Hundred Ten, alt. Nineteen Ten (1910), Nineteen Fifty-two (1952) Chevrolet, not One Thousand and Fifty-two Chevrolet. Moving on to the Twenty Hundreds, Twenty Hundred One or if you like, Twenty "O" One (2001), Twenty Twenty (2020) Chevrolet, not Two Thousand and Twenty Chevrolet. Let's stick with the historical pattern, 'till the end of the solar system. Come to think about it, at some point, we may have to switch the calendar year to exponential notation.

Wait so it’s complicated what I’m thinking but basically aren’t we always going through a new rotation every day or second if we consider that the way we orbit is that we start from 0 degrees to 360 but what if we instead orbit or rotate from 1 degree all the way around to 0 doing a different rotation or orbit and again we start at 2 degrees then rotate then we at 1 degree and yeah so wouldn’t that mean every time the earth moves 1 degrees in orbit we do a new rotation making it possible to have more then 1 new year eve
Andrew Siegel
2 päeva tagasi
@Joel Campos that would be the same orbit. The place in the orbit that we say it's a new year is completely arbitrary. We could say that the place we are in the orbit right now is the start of the year if we changed the calendar and made October 19th the first day of the year. There's nothing special about where Earth is January 1st, humans just decided thats would be where the year starts for the calendar we use. Different calendars have different days the year starts on. That's why there's a Chinese New year.
Joel Campos
2 päeva tagasi
Andrew Siegel I know that but let’s say that we have a circle thats 365 spaces everyday is one space we move and we go 365 spaces for a year but what if we start at instead of 0 but 1 then we add 365 and go back to 1 again wouldn’t that make a separate entirely different orbit
Andrew Siegel
2 päeva tagasi
@Joel Campos everyday the Earth rotates one time around its axis. The amount of time it takes Earth to rotate 365 times is the same amount of time as it takes for the Earth to orbit the Sun once. Changing the amount of time it takes Earth to rotate will not change the length of a year because of the third law of planetary motion.
Joel Campos
2 päeva tagasi
Andrew Siegel I’m saying that doesn’t every day mean we complete a full orbit around the sun because if we just change at when we complete an orbit wouldn’t that possibly mean everyday we complete a full orbit around the sun
Andrew Siegel
2 päeva tagasi
Can you rephrase your question please. Are you talking about changing Earth's rotation in order to have multiple years in one orbit around the Sun? That would Make one year more days and it would be the same amount of time because the Earth would rotate faster.

Andrew Siegel
2 päeva tagasi
The Shkadov thruster is extremely thin in order to be supported by radiation pressure. If it was thicker the sun's gravity would be stronger than the radiation pressure and would pull the thruster into the sun.

if a bunch of asteriods came coming at earth, isn't there a more passive way of blocking it? like intercepting them in space with missles or something?
Andrew Siegel
2 päeva tagasi
Right now if a large asteroid was detected on a collision course with Earth 10 years before it would collide with Earth a spacecraft that impacts the asteroid could change it's orbit. It's like the butterfly effect if you have a small change of the initial conditions you can have a massive effect. Even though the asteroids speed and direction would only be changed by a tiny bit over long enough periods of time this can change its orbit.

I came from Isaac Arthur's channel, and that Caplan Thruster is the most metal way I've ever seen for interstellar travel. Imagine an alien race sees us coming to their galaxy to make first contact. They're expecting a ship and we show up with the whole solar system. Humanity: "We couldn't decide what to bring or who to send so we just brought everyone and their kitchen sinks". Aliens: "huh". Caplan Thruster: "Om nom nom nom brrrrrrrrrrrrrrrr".
