The Cosmos

The cosmos will always be a mystery to us. Each new discovery only adds to the mystery.

Here are some interesting fun facts about what is out there – courtesy of Facebook pages ‘Weird Facts’, ‘Unbelievable Facts’, ‘Today I Learned’, ‘Science and Facts’, ‘The Knowledge Factory’, ‘The Study Secrets’ etc… However, I do not know if they are true. Some of them sound really incredible.

Light Can Orbit a Black Hole

Around a black hole, gravity is so intense that it bends not only matter, but space and time itself. At one very precise distance called the photon sphere this curvature is just right for light to move in a circular path.

Normally, light always travels in straight lines. Near a black hole, those “straight lines” become curved paths through warped spacetime. At the photon sphere, gravity pulls inward with exactly the right strength to keep light looping around the black hole instead of flying away.

This orbit is extremely unstable.
A tiny push inward → the light falls into the black hole.
A tiny push outward → the light escapes into space.

Because countless light paths skim this region, the photon sphere plays a major role in what we see in black hole images. It helps create the bright ring seen around black holes, where light has been bent, delayed, and wrapped around multiple times before reaching us.

So while nothing can escape once it crosses the event horizon, just outside it, light can briefly dance in circles, tracing one of the most extreme effects of gravity in the universe. – A Facebook post

Earth, in all its beauty and complexity, is just one small part of a vast and ever-expanding universe. With 3.2 trillion planets in our galaxy alone, it’s hard to fathom the sheer scale of our existence. The Sun, which we see as the center of our world, is just one of 200 billion stars in the Milky Way. And the Milky Way itself is only one of the 2 trillion galaxies in the observable universe. These mind-boggling numbers leave us questioning our place in the grand cosmic design.

This image of Earth, bathed in the stunning colors of the cosmos, serves as a humbling reminder of how tiny we are in the grand scheme of things. Yet, while the universe may seem overwhelmingly vast, it also invites a sense of wonder. Each star, planet, and galaxy holds its own mysteries, waiting to be uncovered. The beauty of our existence lies not in its insignificance, but in the endless possibilities it offers for exploration and discovery.

In the face of such vastness, it's easy to feel small. But this image also sparks a deeper curiosity. If Earth is but a speck in the cosmos, what does that mean for our understanding of reality, existence, and the forces that shape our lives? The universe is full of questions, and each discovery leads to even more mysteries. As we look out into the stars, we are reminded that the journey of exploration is never truly finished—it is ongoing, ever-expanding, and full of infinite possibilities.

This perspective challenges us to think beyond our immediate surroundings and to appreciate the interconnectedness of all things. The universe, in its infinite complexity, provides a sense of unity that transcends borders, species, and ideologies. By understanding our place in this vast expanse, we open ourselves up to new ways of thinking, greater empathy, and a deeper appreciation for life. – A Facebook post by ‘Earth We Are One’

A Structure So Big It Shouldn't Exist Just Broke Cosmology.

For decades, our understanding of the universe has been built on a single, fundamental bedrock called the "Cosmological Principle." It states that on the grandest scales, the universe is smooth and uniform, like a vast, calm ocean. But astronomers have just discovered a Titanic-sized iceberg that shatters this rule: a colossal ring of galaxies so enormous it defies all our models of how the cosmos should look. This structure is a glaring anomaly, a scar on the face of the universe that suggests our most basic laws of physics might be wrong on the largest scales. Its existence hints at unknown, titanic forces from "beyond" our current understanding that sculpted this impossible ring. What colossal, unseen hand carved this into the fabric of the cosmos? – A Facebook post by ‘Amazing World’.

We just found Earth's cosmic next-door neighbors! After half a century of hunting through the stars, astronomers have discovered the closest exoplanets ever detected, orbiting a star that's practically in our backyard. At just 3 light years away, these newly discovered worlds are closer than any planets outside our solar system have ever been found. This incredible discovery is rewriting what we know about our local corner of the universe. - A Facebook post by 'Good News Daily'
