#نسبیت_عام
نظریه نسبیت عام (General Relativity) که توسط آلبرت اینشتین در سال 1915 ارائه شد، یکی از بنیادی‌ترین نظریه‌های فیزیک مدرن درباره گرانش است. این نظریه جایگزین نظریه گرانش نیوتونی شد و تصویری عمیق‌تر و دقیق‌تر از گرانش ارائه داد.

---

✅ خلاصه‌ی نظریه‌ی نسبیت عام:

نسبیت عام می‌گوید:
گرانش ناشی از انحنای فضا-زمان است که به‌وسیله‌ی جرم و انرژی اجسام ایجاد می‌شود.
به بیان ساده‌تر، ماده فضا-زمان را خم می‌کند و این خمیدگی، مسیر حرکت اجسام را تعیین می‌کند.

---

🌌 پیش‌بینی‌های کلیدی نظریه نسبیت عام:

1. خم‌شدن نور در میدان گرانشی (تأیید شده توسط آرتور ادینگتون در سال 1919)

2. انقباض زمان در میدان گرانشی (تأیید شده در ساعت‌های دقیق روی ماهواره‌ها و زمین)

3. پیش‌روی پریهلون مدار عطارد (توضیحی که نیوتون از آن ناتوان بود)

4. وجود سیاه‌چاله‌ها (با شواهد قوی تأیید شده؛ عکس افق رویداد ۲۰۱۹)

Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure.
