The destiny of the time travelers is so unfortunate

The door of the workshop opened and closed with a loud bang. Accustomed to this situation, Geoff kept to his work without hesitation. But soon after, he couldn’t stand it and shouted to John, who was sighing and puffing loudly.

“Hey, can you be a little quieter!”

“I’m sorry,” John said in an embarrassed tone. “Hey Geoff, can we talk a bit?”

Geoff’s hands, face, and everywhere were dirty. He was working on a second-hand warp engine he took from the garbage. He gazed up at John who looked awful too. He stopped and sat across from John.

The Lessons I’ve Learned in Military High School

I remember the first things that our superiors told us on the first day of our military lives. We were only 13, and they said “from now on you’re not children. We’ll treat you as an adult and we’re expecting the same thing from you.” That was it. We weren’t a child anymore.

It’s been 5 years since I graduated from the Navy. Nowadays, I can clearly see that was a breaking point for me and all my friends. We become both of them — a child and an adult at the same time. That’s what I observed. Sometimes, we’re…


How the theory of everything creates a multiverse madness?

“String theory envisions a multiverse in which our universe is one slice of bread in a big cosmic loaf. The other slices would be displaced from ours in some extra dimension of space.” — Brian Greene

The ultimate point in the physical description of the universe: ‘the theory of everything’. This concept is an expression of the effort to unite the four fundamental forces in nature: the electromagnetic force, the strong and weak nuclear forces, and gravity.

String theory came to the fore in the last quarter of the 20th century as an attempt to find this compound theory. The…


Interesting and scientific truths about the cosmic monsters of our universe

“So Einstein was wrong when he said, “God does not play dice.” Consideration of black holes suggests, not only that God does play dice, but that he sometimes confuses us by throwing them where they can’t be seen.” — Stephen Hawking

I think we wouldn’t be wrong if we say that black holes are one of the most interesting and mysterious celestial bodies in our universe. Even light cannot escape the gravitational force of these cosmic monsters, which have almost infinite density, if they get close enough.

Black holes are enormous things that can bend the space-time continuum, and even…


“Well, the way of paradoxes is the way of truth. To test reality we must see it on the tight rope. When the verities become acrobats, we can judge them.” — Oscar Wilde

The Earth reveals the concepts of day and night with its rotations around itself. While the side facing the sun experiences the day, the night is experienced on the other side. Although the answer to our question seems at first to be explained by the disappearance and setting of the sun from the horizon, the answer is not that simple.

While we have reason to believe that the Universe is not infinitely large (which is contrary may be true), it is so large that we can assume it is infinite. In this case, we should see a star at every…


Those were the days life continued in different layers of reality

Clifton, now in his 70s, was still amazed at the impact his inventions had on society. He had been a member of the team working on quantum processors (QPs).

“In those days, I was always thinking about the form of reality. And in the meantime, I was working on a technology that seemed the exact opposite of it,” he said with a twisted smile.

“I thought there’re two different realities.”

“One is the physical reality — the universe we’ll never comprehend. And the other is the mental reality — a reality dictated by culture, environment, belief…” he suddenly stopped.

“Though,”…


“There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.” ― Douglas Adams

The cosmological evolution from Ancient Greece to the present has led to the emergence of many different universe models. In early times, these models were simple, claiming that the Earth was at the center of the universe and everything else revolved around this center.

The validity of such claims lasted until the 16th century. First Copernicus and then Isaac Newton showed these models should be removed.

Still, the newly painted universe was a simple one. According to Newton, the universe was a fixed space scene that has existed since eternity and will exist forever. …


Messing with the past takes you and puts you into the future

His sweaty hands were trembling while doing the final adjustments on the vehicle. Hugh Leslie had become a wretch with all the stress of years and many unsuccessful attempts.

He was alone in his workshop, if the ball of dough he called isotope wasn’t counted. “I’m close to the end,” he said, looking at the isotope.

Leslie had worked on Kurt Gödel all his life. He was obsessed with his theories, especially the spinning universe model.

Though he knew that Gödel’s universe model didn’t agree with cosmological observations, there was one thing he was sure of. …


“… to build a machine smarter than you, it has to be more complex than you — and the ability to understand the machine begins to slip away.” — D. Eagleman, Sum: Tales from the Afterlives

Neural networks are, in a nutshell, a subfield of machine learning algorithms that are inspired by neurons in the human brain.

Nowadays, AI technology that is powered by neural networks is everywhere. They became the core of just about everything we do, including language translation, virtual recognition, text summarization, autonomous vehicles, speech recognition, game-playing, and so on — it’s up to your imagination. For instance, there would be no apple pencil or voice commend assistants(siri, alexa, etc.) without neural networks.

Since they power almost anything that we use, I think it’s necessary to understand some of the general terminologies and…


“Astronomy compels the soul to look upwards and leads us from this world to another” — Plato

As humanity, we have always found the sky fascinating since ancient times, and our curiosity towards it has survived until today without ever running out.

In the early eras, people used knowledge of the sky for the benefit of organizing and facilitating daily life. Today, we are sending vehicles to different celestial bodies and even talking about plans to settle on extraterrestrial planets such as Mars.

Before moving on to the historical events of our curiosity about the universe, let’s talk a little…
