⭕️ پس از بیگ بنگ چه اتفاقی افتاد؟!

یک ثانیه بعد از بیگ بنگ ، دما به ۱۰^۱۰ درجه کلوین افت می کند، حال الکترون ها و پادالکترون ها نیز همدیگر را نابود می کنند و جز مقدار ناچیزی(۹-^۱۰قسمت آن) باقی نمی ماند؛ از این مقدار ناچیز الکترون مواد آینده هستی به وجود می آید. پس از ۱۰ ثانیه که از بیگ بنگ می گذرد، دما به ۹^۱۰ کلوین می رسد. پروتون ها و نوترون ها از طریق همجوشی هسته ای اولین هسته اتمی را به وجود آوردند.به این مرحله هسته زایی می گویند. در این مرحله %۲۵ ایزوتوپ هیلیم ۴ و ۰٫۰۰۱ % ایزوتوپ های هیدروزن سنگین یا دوتریم،D و همچنین مقدار بسیار ناچیزی ایزوتوپ هیلیم ۳ تولید می شود، %۷۵ بقیه پروتون ها بعد ها هسته اتم هیدروژن را ساختند.

بعد از ۵ دقیقه از هسته سازی بیگ بنگ، نوترون های آزاد باقی مانده دیگر ثابت نبودند و به تدریج به پروتون و الکترون تبدیل شدند. بقیه عناصر سنگین بعدها درون ستارگان به وجود آمدند. بعد از خود سیصد هزار سال دما به ۳۰۰۰ درجه کلوین افت کرد، در این شرابط پروتون ها و نوترون ها و الکترون ها توانستند اتم های پایدار به وجود آوردند و نور توانست بدون مانع به حرکت خود ادامه دهد.

How to Create a Custom Theme in Telegram for Desktop and Mobile

Like most instant messaging apps, Telegram helps facilitate communication. Its increasing popularity among social media users can be largely attributed to its enhanced privacy and encryption features. Also, its support for large group chat features has seen the app’s user count grow to 700 million monthly active users. The app has introduced several personalization features to maintain the interests of its users. One of such personalization options available to users is the creation of customized themes. Instead of using the default theme that typically comes with the Telegram app, users can now create theirs. Users can also share the created themes with the public. Here’s how you can create a custom Telegram theme on your desktop or mobile.

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.
