📡 اولین شواهد رصدی از نظریه ریسمان⁉️

🧵 آیا ممکن است بالاخره نظریه ریسمان – یکی از جنجالی‌ترین نظریه‌های فیزیک نظری – ردپای خود را در داده‌های رصدی برجای گذاشته باشد؟

در فروردین ۱۴۰۴ (آوریل ۲۰۲۵)، گروهی از فیزیک‌دانان نظری با انتشار یک مقاله‌ی پیش‌چاپ در arXiv، مدعی شدند که برای نخستین بار شواهدی رصدی در حمایت از نظریه ریسمان یافته‌اند. این پژوهش، با تحلیل داده‌های ابزار طیف‌سنجی انرژی تاریک (DESI)، نشان می‌دهد که شتاب انبساط کیهان در حال کاهش است؛ پدیده‌ای که مدل استاندارد کیهان‌شناسی قادر به توضیح آن نیست.

مدل ارائه‌شده در این مطالعه، رفتار غیرتبادلی فضا-زمان (non-commutative spacetime) را در نظر می‌گیرد؛ ویژگی‌ای که در نظریه ریسمان پیش‌بینی شده و می‌تواند به‌طور طبیعی شتاب کیهانی را توضیح دهد. این مدل با مشاهدات اخیر DESI هم‌خوانی دارد و نشان می‌دهد که انرژی تاریک به‌مرور زمان کاهش می‌یابد.

اگر این نتایج تأیید شوند، می‌توانند نخستین شواهد تجربی برای نظریه ریسمان و گرانش کوانتومی باشند. این یافته‌ها نه‌تنها به حل معمای انرژی تاریک کمک می‌کنند، بلکه پلی بین فیزیک کوانتومی و کیهان‌شناسی برقرار می‌سازند.

📎 برای علاقه‌مندان به فیزیک بنیادی و کیهان‌شناسی، این خبر می‌تواند نقطه عطفی تاریخی باشد.

What is Telegram?

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.

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.

Q: Who is Telegram for?

Telegram is for everyone who wants fast and reliable messaging and calls. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options. You can appoint admins with advanced tools to help these communities prosper in peace. Public groups can be joined by anyone and are powerful platforms for discussions and collecting feedback.In case you're more into pictures, Telegram has animated gif search, a state of the art photo editor, and an open sticker platform (find some cool stickers here or here). What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. 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. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.

Q: Can I make calls via Telegram?

Yes! Voice calls are currently available to users around the world.

Many modern travelers appear to struggle with managing various aspects of their finances simultaneously while abroad, such as banking, budgeting, investing, trading, and saving. It is important to have apps installed on the device that will help you carry out these necessary tasks.
