Soon the earth will (possibly) be hit by comets / asteroids.

English (Google-assisted translation):

This is perhaps the most important message I have ever written / will write in my life.

Not long ago / a few days ago I saw a broadcast on television, on discovery channel or national geography, I don't know exactly which one anymore.

In that TV program it was told that scientists have discovered something (they are learning more and more about the universe and our solar system).

What these scientists, as far as I have understood, have discovered is that OUR SUN behaves like a kind of swing, moving up and down through the universe.

It swings, as it were, I don't know how exactly, it will probably be an up and down motion.

What they now think they have discovered is that this up and down movement takes about 65 million years, or grab it for 33 million years, cyclically or something. As you can see, I don't fully understand it (yet). The information was scarce and no good animations / nothing at all except this piece of information.

Why is this up and down motion / fluctuation a problem, now:

In the universe itself rotate / are debris, comets, asteroids ... a kind of belt / belt of these objects ... these objects / debris are at a certain height so I assume.

OUR SUN is about to enter that belt ... Our earth is drawn by OUR SUN.

In other words, our entire solar system will soon be pulled through that belt.

This explains to me and to me the recent increase in observations of asteroids and comets and even interstellar objects that come from outside our solar system.

Two of these objects have already been observed in just two years! A record !

In addition, other asteroids right next to the earth have passed by and were only discovered when they were already past, even between earth and moon! Apart from a hair!

The dinos are said to have died out because of such an impact 65 million years ago. We are now about to experience the same thing.

My / our HOOP is now NASA, and possibly ESA, who are planning to launch a satellite to better visualize these objects and discover more.

However, this satellite will only be launched in a few years, maybe it's already too late, maybe not.

A real solution to protect our earth against such an impact is not there yet.

It is in the interest of all people on this earth that:

1. This is further investigated how it works.
2. This WITH URGENT education is taught at primary and secondary schools.
3. More financing is going to solve this problem.
4. A competition with prize money may be organized to destroy or divert an object.

I didn't really know about this problem until recently. I will also post this on politics.nl.

I hope that work will be done soon. Mankind has invested a lot in the earth, if not practically everything, so it pays to invest in this, this security, to protect this huge investment in the earth.

My hope is that by teaching children in primary and secondary schools there is more interest in this problem and there may be a new generation of people who will tackle this problem with fresh and renewed energy.

This will be necessary anyway, it is probably not a question of whether there will be a major impact but only when. Now it seems that our time is almost up. So there is almost a bidding.

It is tempting to think that it might take another million years or a few hundred thousand years or a few thousands of years, but what if it isn't?!? Recent discoveries are quite an alarm.

Partly perhaps because more is being looked at and searched, but that does not really matter, there is more and more insight into how dangerous it is in space, that is a good development, but I think most people are unaware of this and that will have to change quickly, especially if the aforementioned discovery is indeed true and correct, I am not comfortable with it anyway

I have the feeling that it could well be wrong.

If someone has more information or links about the new discovery, I would like to read that, just mention here some links or keywords to look up in Google.

Greetings,
Skybuck.

Our Motion Through Space Isn't A Vortex, But Something Far More Interesting

The Universe is out there, waiting for you to discover it.

There are a lot of moving parts to the Universe, as nothing exists in isolation. There are literally trillions of large masses in our Solar System, all orbiting around the galactic center on timescales of hundreds of millions of years. But there's a viral video, parts 1 and 2, that claims that as the Solar System moves through the galaxy, it makes a vortex shape, pulling the planets behind it as it does.

But our true cosmic address, and our real cosmic motion, is far more complex and interesting than a mere model such as this. Which is fascinating, because it's all governed by one simple law: General Relativity. On the largest scales, it's only gravity that determines the motion of everything, including us, as we move through the Universe.

Qualitatively, the "vortex video" has a few things right. It shows the following true facts:

The planets orbit the Sun, roughly in the same plane.
The Solar System moves through the galaxy with about a 60° angle between the galactic plane and the planetary orbital plane.
The Sun appears to move up-and-down and in-and-out with respect to the rest of the galaxy as it revolves around the Milky Way.

Today In: Innovation

And those things are true. But none of them are true the way they’re shown in the video. And that’s the important difference between qualitative and quantitative.
On the largest scales, it isn't just the Earth and the Sun that move, but the entire galaxy and local group, as the invisible forces from gravitation in intergalactic space must all be added up together.

And quantitatively, we not only predict, but can measure, exactly how our motion works. It isn't a vortex, but what it is, exactly, is fascinating.

Here we are, on planet Earth, which spins on its axis and revolves around the Sun, which orbits in an ellipse around the center of the Milky Way, which is being pulled towards Andromeda within our local group, which is being pushed around inside our cosmic supercluster, Laniakea, by galactic groups, clusters, and cosmic voids, which itself lies in the KBC void amidst the large-scale structure of the Universe. After decades of research, science has finally put together the complete picture, and can quantify exactly how fast we're moving through space, on every scale.
Within the Solar System, Earth's rotation plays an important role in causing the equator to bulge, in creating night-and-day, and in helping power our magnetic field that protects us from cosmic rays and the solar wind.

The planets both rotate on their axis and revolve around the Sun. Even though you perceive yourself as stationary, we know — at a cosmic level — that simply isn't true. As the Earth rotates on its axis, it hurtles us through space at nearly 1700 km/hr for someone on the equator. That might sound like a big number, but relative to the other contributions to our motion through the Universe, it's barely a blip on the cosmic radar.

That’s not really all that fast, if we switch to thinking about it in terms of kilometers per second instead. The Earth spinning on its axis gives us a speed of just 0.5 km/s, or less than 0.001% the speed of light. But there are other motions that matter more.
The speed at which planets revolve around the Sun far exceeds the rotation speeds of any of them, even for the fastest ones like Jupiter and Saturn.

Much like all the planets in our Solar System, Earth orbits the Sun at a much speedier clip than its rotational speed. In order to keep us in our stable orbit where we are, we need to move at right around 30 km/s. The inner planets — Mercury and Venus — move faster, while the outer worlds like Mars (and beyond) move slower than this. The difference is severe: Mercury makes about 4 orbits for every 1 of Earth's, and it takes Neptune over 160 Earth orbits before it's completed even one revolution.

Moreover, as the planets orbit in the plane of the solar system, they change their direction-of-motion continuously, with Earth returning to its starting point after 365 days. Well, almost to its same exact starting point.
An accurate model of how the planets orbit the Sun, which then moves through the galaxy in a different direction-of-motion. Note that the planets are all in the same plane, and are not dragging behind the Sun or forming a wake of any type.

Because even the Sun itself isn’t stationary. Our Milky Way galaxy is huge, massive, and most importantly, is in motion. All the stars, planets, gas clouds, dust grains, black holes, dark matter and more move around inside of it, contributing to and affected by its net gravity. From our vantage point, some 25,000 light years from the galactic center, the Sun speeds around in an ellipse, making a complete revolution once every 220–250 million years or so.

It’s estimated that our Sun’s speed is around 200–220 km/s along this journey, which is quite a large number compared both Earth's rotation speed and its speed-of-revolution around the Sun, which are both inclined at an angle to the Sun's plane-of-motion around the galaxy. Throughout it, though, the planets remain in the same plane, with no "dragging" or vortex patterns emerging.
Although the Sun orbits within the plane of the Milky Way some 25,000-27,000 light years from the center, the orbital directions of the planets in our Solar System do not align with the galaxy at all.

But the galaxy itself isn't stationary, but rather moves due to the gravitational attraction of all the overdense matter clumps and, equally, due to the lack of gravitational attraction from all of the underdense regions. Within our local group, we can measure our speed towards the largest, massive galaxy in our cosmic backyard: Andromeda. It appears to be moving towards our Sun at a speed of 301 km/s, which means —when we factor in the motion of the Sun through the Milky Way — that the local group's two most massive galaxies, Andromeda and the Milky Way, are headed towards each other at a speed of around 109 km/s.
The largest galaxy in the Local Group, Andromeda, appears small and insignificant next to the Milky Way, but that's because of its distance: some 2.5 million light years away. It is moving towards our Sun, at the present moment, at around 300 km/s.

The Local Group, as massive as it is, isn't completely isolated. The other galaxies and clusters of galaxies in our vicinity all pull on us, and even the more distant clumps of matter exert a gravitational force. Based on what we can see, measure, and calculate, these structures appear to cause an additional motion of approximately 300 km/s, but in a somewhat different direction than all the other motions, put together. And that explains part, but not all, of the large-scale motion through the Universe. There's also one more important effect at play, one that was quantified only recently: the gravitational repulsion of cosmic voids.

For every atom or particle of matter in the Universe that clusters together in an overdense region, there's a region of once-average density that's lost the equivalent amount of mass. Just as a region that's more dense than average will preferentially attract you, a region that's less dense than average will attract you with a below-average amount of force. If you get a large region of space with less matter than average in it, that lack-of-attraction effectively behaves as a repellent force, just as extra attraction behaves as an attractive one. In our Universe, opposite to the location of our greatest nearby overdensities, is a great underdense void. Since we're in between these two regions, the attractive and repulsive forces add up, with each one contributing approximately 300 km/s and the total approaching 600 km/s.

When you add all of these motions together: the Earth spinning, the Earth revolving around the Sun, the Sun moving around the galaxy, the Milky Way headed towards Andromeda, and the local group being attracted to the overdense regions and repulsed by the underdense ones, we can get a number for how fast we're actually moving through the Universe at any given instant. We find that the total motion comes out to 368 km/s in a particular direction, plus or minus about 30 km/s, depending on what time of year it is and which direction the Earth is moving. This is confirmed by measurements of the cosmic microwave background, which appears preferentially hotter in the direction we're moving, and preferentially colder in the direction opposite to our motion.
The leftover glow from the Big Bang is 3.36 millikelvin hotter in one (the red) direction than average, and 3.36 millikelvin cooler in (the blue) the other than average. This is due to the total motion of everything through space.

If we ignore the Earth's rotation and revolution around the Sun, we find that our Solar System is moving relative to the CMB at 368 ± 2 km/s. When you throw in the motion of the local group, you get that all of it — the Milky Way, Andromeda, the Triangulum galaxy and all the others — are moving at 627 ± 22 km/s relative to the CMB. That larger uncertainty, by the way, is mostly due to uncertainty in the Sun's motion around the galactic center, which is the most difficult component to measure.

We know exactly how the Earth moves through the Universe, and it's both beautiful and simple. Our planet and all the planets orbit the Sun in a plane, and the entire plane moves in an elliptical orbit through the galaxy. Since every star in the galaxy also moves in an ellipse, we see ourselves appear to pass in-and-out of the galactic plane periodically, on timescales of tens of millions of years, while it takes around 200-250 million years to complete one orbit around the Milky Way. The other cosmic motions all contribute, too: the Milky Way within the Local Group, the Local Group in our Supercluster, and all of it with respect to the rest-frame of the Universe.

The Solar System isn't a vortex, but rather the sum of all our great cosmic motions. Thanks to the incredible science of astronomy and astrophysics, we at last understand, to tremendous precision, exactly what that is.

For every atom or particle of matter in the Universe that clusters together in an overdense region, there's a region of once-average density that's lost the equivalent amount of mass. Just as a region that's more dense than average will preferentially attract you, a region that's less dense than average will attract you with a below-average amount of force. If you get a large region of space with less matter than average in it, that lack-of-attraction effectively behaves as a repellent force, just as extra attraction behaves as an attractive one. In our Universe, opposite to the location of our greatest nearby overdensities, is a great underdense void. Since we're in between these two regions, the attractive and repulsive forces add up, with each one contributing approximately 300 km/s and the total approaching 600 km/s.
