What If Earth Was Near the Center of the Milky Way?


See that strip of stars splashed across the night sky? That’s our home galaxy, the Milky Way. You can see it from Earth because we live right on the outskirts, far away from all the fun stuff happening in its center. The Milky Way is huge – about 100,000 light-years across. It has four large, spiral
arms encircling its center. That makes it a barred spiral galaxy, just like most galaxies in
the observable universe. If the Earth packed up its belongings and moved to the heart of the Milky Way, things would be looking pretty bleak for the survival of any kind of life on the planet. But not because of the Milky Way’s
supermassive black hole… The Earth is located in a quiet neighborhood in one of the smallest spurs
of the Milky Way – the Orion Arm. We’ve got approximately 27,000 light-years between us and the galactic center. It’s a comfortable spot to live in. The temperatures on Earth are
just right to sustain life. And there aren’t too many space hazards
that could wipe out our existence. I didn’t say it’s completely safe, did I? Living anywhere near the center
of the Milky Way would be… different. It would depend on what part of that center the Earth had the misfortune to occupy. The closer you get to the heart of the galaxy, the tighter the stars are packed together. Because of this high star density,
the Earth would be blasted with a lot more radiation than what
the Sun throws at you right now. Under these circumstances, the odds of life ever evolving would be pretty small. But if the Earth moved to the center
together with all its inhabitants, you’d find yourself very unlucky. Earth’s magnetosphere
wouldn’t be able to protect you from space radiation
blasting from all directions. This could change the Earth’s climate, and cause everything on the
planet to either mutate or die. If you lived, your biggest concern would be a close encounter with a supernova. A supernova occurs when
a massive star collapses releasing radio waves, X-rays, cosmic
rays and gamma rays into space. For all we know, one massive stellar body could throw the Earth out of the Sun’s orbit. Our planet would be
surrounded by foreign stars until one of them exploded in a
supernova and wiped us out for good. But it would look spectacular from Earth, if only for a brief moment. There’s another big hazard that
lies within the Milky Way’s center – a supermassive black hole
called Sagittarius A*. If getting sucked into a black
hole isn’t on your to-do list, consider yourself lucky. The Earth might stay far enough from it that we wouldn’t get
engulfed by this cosmic beast. But we could get close enough to
get caught in the black hole’s orbit. At a distance of 20 billion km (12 billion mi) from the black hole’s event horizon, the Earth could develop a speed
of 25 million km/h (15.5 million mph). That’s over 230 times faster than the speed our planet
is moving at right now. It sure wouldn’t be good for you, or anything else on the Earth’s surface. The Earth is perfectly designed
to be right where it is. It can survive on the outskirts of the galaxy, but you wouldn’t want it to be anywhere else. The most dangerous place
for a planet to be located is anywhere near the center
of a galaxy – any galaxy. If you want a nice view, your best bet might be to teleport the
Earth to the middle of a nebula instead. But that’s a story for another WHAT IF.

  1. Seems like a bunch of nothing…are stars really that close near the center? Our sun would still be closest and doesn't blow away the magnetosphere. Sure, supernova might be a problem, but you said in another video that ones 50-100ly away wouldn't affect us …and they're not happening all that frequent..so does any of this actually make sense? IMO there should be quite a few spots near the center that wouldn't affect us all that much

  2. Can you turn down the dramatic and commercial tone in your videos and just try to be a bit more informative and educational? It's really annoying.

  3. There's not much life out there. People argue there must be tons of life out there. But I haven't seen any. And I don't believe in Aliens, UFO crashes, and ET's, X-Men, and on and on. I don't require all this fantasy to experience love in my life. Love can be experienced with a kind word and a friendly gesture. Love doesn't require a UFO nor an Alien.

  4. This just goes to show… Don't do drugs and pay attention to in school… Huh I screwed up like nobody realized if that on smart person didn't pay attention where would we be what would have happened and we all set around having a great time… But sometimes I wish I would have paid more attention in school.
    Seriously kids, not a joke please pay attention it'll bite you like snake in the end.

  5. Pretty sure that night sky is something only visible in the southern hemisphere cause here in America I dont see anything remotely close to that.

  6. What if we are in an ancestor simulation? And after we die here, we actually wake up in a post scarcity civilization, that is using black holes for energy, because only black holes, neutron stars, white dwarfs, and iron stars exist to get energy from?

  7. "If getting sucked into a black hole isn't your to-do list, consider yourself lucky."

    Wait, wh- lucky? Isn't it just "consider yourself a non-risk-taker?" "Not an idiot." "Not desperate."
    Somewhere along those lines?

  8. Every damn video is the same. It is always death death death. Come on what if give a happy ending for once.

  9. We would die, it is that simple. In order for life to be possible we have to be around 15,000-30,000 light years away from the center of the galaxy. We are around 25,000 light years. Living in the Goldilocks zone of the galaxy where life is possible therefore we exist and live.

  10. This is lovely sensationalism, but it isn't really accurate science. It depicts the center of the milky way as a lot more hostile than it is.

    If we were 95% closer to the center of the galaxy, odds for something going wrong go up, slightly, but that's about it. Stars are still spaced 3-6 light years on average (often further than our nearest neighboring system, Alpha Centauri, at ~4LY), in the galactic core, until you get very, very close to Sagittarius-A – even there, some systems may orbit relatively unmolested for billions of years. For the bulk of the systems in the core, external stellar radiation isn't any worse than it is here.

    3:30 is particularly egregious. Our system orbits the galaxy at roughly 500,000mph. If it was traveling 10 or even 100 times that, odds are it'd make no difference to us, save that the constellations might shift about enough for one to notice in a single lifetime. There's no resistance in space, and the sun is close enough to keep all the planets in their orbits at anything short of relativistic speeds near the speed of light. (Though passing near a large massive object might knock a lotta nasty comets out of the ort cloud for some potential mayhem.)

  11. who thought that if the earth enters the Milky Way the earth would be teleported to another place, Paradies 😂

  12. Just because we would be moving fast though space doesn't mean that everything would get destroyed. It's really if we suddenly speed up or suddenly stop that problems would arise. If it's gradual then it shouldn't be an issue.

  13. The more I learn about this fascinating universe and science the more I believe in God (aggressive atheists are asked to refrain from comments)

  14. Sorry, I don't think we live in or near a black hole we never have seen the center of the galaxy. Because how come light is at its center seen I thought no light cant escape a black hole. What if a galaxy was just like how solar systems work but with tons of systems like ours orbiting it. What if its the world tree that old myths talk about we dont have the tech to find out ever.

  15. I must be blind because I read the title as “What if the Earth was in The Milky Way” and for a second I thought I completely misunderstood the universe.

  16. 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂

  17. The Solar System (and Earth) is located about 25,000 light-years to the galactic center and 25,000 light-years away from the rim. So basically, if you were to think of the Milky Way as a big record, we would be the spot that's roughly halfway between the center and the edge.

    Today, the Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun. But this tilt changes. During a cycle that averages about 40,000 years, the tilt of the axis varies between 22.1 and 24.5 degrees. Because this tilt changes, the seasons as we know them can become exaggerated.

  18. Pls don’t tell me we’re gonna get wiped out by a super nova 😭🥺I’m too young to dieeee 😭😭😭😭😭

  19. IF SOLAR SYSTEM OF PLANET EARTH ARE CLOSED TO THE CENTER OF GALAXY ALL LIVING LIFE IN EVERY PLANET HAVE A STRONG INTILLIGENT LIKE THE ALIEN AND NEVER DIE AND THE PROBLEM OF HUMAN WHY CANNOT REACH THE STRONG INTILLIGENT AND IMMORTALITY ARE THE TYPE OF DNA, WEAK OR ANIMAL TYPE,, THIS TYPE OF DNA CANNOT USE THE STRONG INTILLIGENT AND CANNOT USE A BIG SUN BECAUSE ALL WILL DIE IN CANCER AND OTHER KILLER DISEASE

  20. stop this nonsense you creators of this video are humans with parents and biological needs like the rest of us dont ask hard questions.

  21. I thought this would be the one what if that we dont die and it would end with a beautiful, happy ending but nooooooo😒

  22. ⵙⵜⴻⵒⵀⴻⵏⵎⴰⵜⵜⵀⴻⵡⴷoⵎⵉⵏⴳⵓⴻⵣⵊⵔⴱⵛⴽoⵙⵀⵉⴷoⵎⵉⵏⴳⵓⴻⵣⴱⵛ10ⵒⵍⴰⴳⵓⴻⵙⴱⵙⴽⵉⵏⴰⵙⵀⴻⵙⵙⵒⵉⵔⵉⵜⴰⵙⵀⴻⵙⵙⵒⴰⵛⴻⴰⵙ

  23. Not only humans can live on the universe if volcanic eruptions are normal for us there are other things that considers space danger normal too

    Edit : not only earth species**

  24. I didn't even watch that there is a really strong black hole at the center of the Milky Way so the Earth would be destroyed by that black hole I know I know I know I didn't even watch the video yet
