How is the solar system traveling? Want to know the details?

 Hurtling at 514,000 mph, the solar system bobs up and down through the galaxy like a carousel horse. The last time Earth was in this exact spot, dinosaurs had just begun to evolve.

The Sun and its planets are in a massive orbit around the supermassive black hole at the center of the Milky Way, located about 26,000 light-years away. It takes roughly 225 to 250 million years to complete one full revolution.

The solar system does not travel completely flat along the galactic disk. The plane in which the planets orbit the Sun is tilted at a 60-degree angle relative to the plane of the Milky Way. As the Sun circles the galactic center, it crosses the midplane every 30 million years or so, oscillating vertically in a path that resembles a wave.

Currently, the overall direction of the Sun's trajectory—known as the solar apex—points roughly toward the star Vega in the constellation of Lyra. As the Sun moves toward this apex, it drags the planets along with it while plowing through the interstellar medium.

This forward motion creates a dynamic interaction with the space around it. The solar wind, a constant stream of charged particles emitted by the Sun, blows outward and forms a protective magnetic bubble called the heliosphere. When this outward pressure meets the gas and dust of interstellar space, it creates a bow wave ahead of the solar system, similar to the water parting at the front of a moving ship. This boundary shields the planets from a significant portion of high-energy cosmic rays as the entire system makes its quarter-billion-year journey around the galaxy.

What should people avoid while traveling to Europe?

 I've seen this in Paris, France, Barcelona, ​​Florence... any popular tourist destination will have petty thieves.

These scams vary, and you should read about them before you go, to be aware of them. Some of the ones I've seen:

People in period costumes (mostly Roman centurions) will accuse you of taking photos with them and demand an exorbitant amount of money for the pictures.

People will try to slip an object or a flower into your hands and then demand money. You might have to say " no " very aggressively.

Someone will approach you with a map and ask for directions (their accomplice is behind you while you're distracted, he steals from you).

Someone will place paintings on the ground near monuments like cathedrals, and when you inevitably step on one (because you're looking at the Duomo, not the ground) they'll demand an absurd amount of money for the painting you just stepped on.

Basically, you just have to understand that if you're a tourist in a city, nobody will have a good reason to talk to you. Nobody needs directions from you, nobody needs your signature on a petition; someone trying to stop and talk to you in a major tourist destination is probably up to a scam.

If you find yourself in a situation where someone is demanding money from you (maybe you stepped on a painting or removed that ill-advised painting with the Centurion), simply say:

"Okay, let's find a police officer and I'll pay you in front of the officer ." This usually makes them back down quickly.

Perhaps you have to be aggressive to prevent people from touching you or putting anything on you.

And also, be careful with your belongings. Don't leave your phone on the ground next to you while you're having a picnic by the Seine. It's all about not being an easy target – that's enough to deter people.

That being said, don't let the fear of being robbed stop you from traveling ! Rick Steves has a story about a family who had their passports and thousands of dollars stolen immediately upon arrival in Amsterdam , and they still had an amazing trip .

Simply be aware and have a plan in case the worst happens.

What are some things people don't often talk about when it comes to traveling abroad?

1. Cheap travel souvenirs, such as keychains from New York or refrigerator magnets from Switzerland, are mostly made in China, Vietnam, or Bangladesh and imported.

2. Most shops selling Turkish carpets laid out outdoors are selling fakes.

3. Learning "hello" and "thank you" in the local language will make communicating with locals more enjoyable.

4. When traveling alone, it's important to always take your belongings with you when you go to the toilet.

5. If you are scammed, please do not blame yourself. Being scammed happens to local people from time to time as well.

6. Negotiate the price, but don't lower it too much. Your earnings will probably be more than the store owner has ever seen in their lifetime.

7. It's convenient to download offline Google Maps for your city or area.

8. Please be sure to bring at least one copy of your passport.

9. Popular travel destinations on Instagram may already be overrated and crowded.

10. If someone recommends a tour package to you, don't trust them, as 99% of them are scams.

11. Problems and emotions you encounter while traveling will come with you. Don't expect travel to be a solution to your self-discovery.

12. Animal-related or sexually suggestive tourist attractions, or facilities themed around orphans, are prone to becoming breeding grounds for illegal activities.

13. When asking for directions, it's recommended to get opinions from multiple people, not just one. This is necessary to obtain accurate information.

14. The best travel episodes happen in places with few tourists. My favorite travel memories were created when I brought a physical map and trusted my instincts to choose left or right at intersections.

15. Always purchase travel insurance! This is important whether you have a limited budget or are traveling to a developed country.
