🔸پیش از #آلبرت_اینشتین، فضا و زمان به عنوان دو مفهوم جدا از هم تلقی می‌شدند. اما، اینشتین با نظریه نسبیت خود، نشان داد که فضا و زمان به یکدیگر وابسته هستند و مفهوم فضا-زمان را معرفی کرد.
🔹اما، ما هنوز درک دقیقی از فضا و زمان نداریم. کلید فهم ژرف‌ترین معماها و سؤالات فیزیک در ادارک عمیق‌تر از فضا-زمان نهفته است.

Channels are not fully encrypted, end-to-end. All communications on a Telegram channel can be seen by anyone on the channel and are also visible to Telegram. Telegram may be asked by a government to hand over the communications from a channel. Telegram has a history of standing up to Russian government requests for data, but how comfortable you are relying on that history to predict future behavior is up to you. Because Telegram has this data, it may also be stolen by hackers or leaked by an internal employee. In the past, it was noticed that through bulk SMSes, investors were induced to invest in or purchase the stocks of certain listed companies. And while money initially moved into stocks in the morning, capital moved out of safe-haven assets. The price of the 10-year Treasury note fell Friday, sending its yield up to 2% from a March closing low of 1.73%. As the war in Ukraine rages, the messaging app Telegram has emerged as the go-to place for unfiltered live war updates for both Ukrainian refugees and increasingly isolated Russians alike. Telegram boasts 500 million users, who share information individually and in groups in relative security. But Telegram's use as a one-way broadcast channel — which followers can join but not reply to — means content from inauthentic accounts can easily reach large, captive and eager audiences.
