To understand general relativity, first, let's start with gravity, the force of attraction that two objects exert on one another. Sir Isaac Newton quantified gravity in the same text in which he formulated his three laws of motion, the "Principia."

The gravitational force tugging between two bodies depends on how massive each one is and how far apart the two lie, according to NASA Glenn Research Center. Even as the center of the Earth is pulling you toward it (keeping you firmly lodged on the ground), your center of mass is pulling back at the Earth. But the more massive body barely feels the tug from you, while with your much smaller mass, you find yourself firmly rooted thanks to that same force. Yet Newton's laws assume that gravity is an innate force of an object that can act over a distance.

Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels, according to Wired.

As a result, he found that space and time were interwoven into a single continuum known as space-time. And events that occur at the same time for one observer could occur at different times for another.

As he worked out the equations for his general theory of relativity, Einstein realized that massive objects caused a distortion in space-time. Imagine setting a large object in the center of a trampoline. The object would press down into the fabric, causing it to dimple. If you then attempt to roll a marble around the edge of the trampoline, the marble would spiral inward toward the body, pulled in much the same way that the gravity of a planet pulls at rocks in space.

Гравитационные линзирование

В огромных просторах космоса человечество всегда искало способы понять его тайны. Одним из таких методов являются "Гравитационное линзирование", которые помогают нам наблюдать самые отдаленные и неизвестные части Вселенной.

Что такое гравитационная линза?

Это явление, при котором гравитация космических объектов искривляет световые лучи, работая как линза. Этот эффект был предсказан общей теорией относительности Эйнштейна ещё 1915 году. Световые лучи искривляются при прохождении рядом с массивными объектами, такими как галактики или скопления галактик.

Феномен гравитационного линзирование предоставляет уникальные возможности для изучения далеких объектов, помогает наблюдать отдаленные и слабо-видимые части космоса, так как эффект линзы усиливает освещение. Это позволяет изучать отдаленные звезды, галактики и экзопланеты.

С помощью гравитационных линз ученые могут глубже понять эволюцию и структуру Вселенной, а также изучить природу темной энергии и материи.

Hey everyone!

We're excited to announce a fresh start for a start for our MUBL project! We've been working behind the scenes on exciting changes that we can't wait to share with you soon.

In the meantime, we want to express our sincere gratitude to all of our amazing followers who have stuck with us through thick and thin. Your continued support means the world to us!

Stay tuned for more updates coming soon!

We have sent the results thru email. Applicants, please, check your inbox and spam folder.

We thank you for your patience and pardon for a prolonged time of reaching into conclusion.

After long considerations and discussions, we are announcing the results today.

Just a reminder that only 3 days left.

Hi, guys?. One of my Chinese friends and I are planning for an opportunity where several Uzbek high school or undergraduate students who are interested in astronomy can travel to China for a few days and explore the astronomy observatories and museums at the end of August. Suppose that the trip is entirely for free, would you be able to join? Please leave your reaction or comment if you even have the slightest interest.
(We are now estimating how many people would like to go to design the trip)
My telegram link is @OzodbekA ? if you wanted to reach out to me.
