The great attractor
-
Location: The Great Attractor is located in the direction of the Centaurus and Hydra constellations, roughly 150 million light-years away from Earth. Its position behind the dust clouds of our Milky Way galaxy makes it challenging to observe directly.
-
Gravitational Pull: The Great Attractor possesses an immense gravitational force that influences the motion of nearby galaxies. It acts as a massive attractor, causing galaxies to move towards it at high speeds. This gravitational pull shapes the large-scale structure of the universe.
-
Uncertain Nature: The exact nature and composition of the Great Attractor remain a mystery. Scientists propose various theories, including the possibility of it being a concentration of dark matter or a supercluster of galaxies. Further research and observations are necessary to unravel the true nature of this cosmic phenomenon.
Age of water
A fascinating fact about the age of water on Earth is that some of the water molecules we have today are estimated to be as old as the solar system itself. This conclusion is based on the analysis of isotopes, specifically the ratios of deuterium (a heavy isotope of hydrogen) to regular hydrogen in water samples. By studying these isotopic ratios, scientists have determined that a portion of Earth's water has likely been part of the planet's hydrological cycle since its formation approximately 4.5 billion years ago. This means that the water we use and encounter every day has been cycling through the Earth's oceans, atmosphere, and land for billions of years, making it a remarkable and ancient resource.

Deja Vu effect
Deja vu is a psychological phenomenon characterized by a strong sense of familiarity or the feeling that one has experienced a current situation or event before, despite knowing that it is impossible. While the exact cause of deja vu is not fully understood, several theories have been proposed to explain its occurrence. Here are some of the leading theories:
-
Prevalence: Deja vu is a common phenomenon experienced by a significant portion of the population. Studies suggest that approximately 60-80% of people report having had at least one deja vu experience in their lifetime.
Milkey way galaxy
-
The Milky Way Galaxy was born about 12.7 years ago, and is still expanding rapidly today.
-
According to scientists, 6 to 7 new stars are born every year in our milky way galaxy and every year a light star dies and turns into a planetary nebula.
-
Our solar system is 27,000 light years away from the center of the Milky Way galaxy.
-
Our milky way galaxy travels through space at a speed of about 583 KM/S, and it is expanding at a speed of 1770 KM/H.
-
At the center of our Milky Way galaxy is the SAGITTARIUS A* black hole with a mass 4.3 million times that of our Sun.
Speed of Light
-
The speed of light in a vacuum is approximately 299,792,458 meters per second (or about 186,282 miles per second). This speed is denoted by the symbol "c" in physics equations.
-
Light travels at a constant speed in a vacuum, regardless of the source or the observer's motion. This is one of the fundamental principles of physics.
-
The speed of light is incredibly fast. For example, light from the Sun takes about 8 minutes and 20 seconds to reach Earth, even though the distance is about 93 million miles (150 million kilometers).
-
The speed of light is the fastest known speed in the universe. According to our current understanding of physics, no object with mass can reach or exceed the speed of light.
Travel at speed of light
If we travel at the speed of light, what will the universe look like, then understand that when we drive in the rain, the rain water hits the windshield of the car, as the speed of the car increases, the water hits more diagonally and today The concept applies to spaceships and interstellar space in the universe, where the spaceship traveling at the speed of the universe appears in 2D form in a frame against the light of the surrounding stars.
MIT University has done one such fun experiment in which it has shown what it feels like to go back and forth at the speed of light. (Download link is below)

Speed of Light 2
-
The fastest moving thing in our universe is light, which moves at a speed of 300,000 kilometers per second.
-
You will be surprised to know that light takes 1.3 seconds to reach the moon from earth and it takes 182 seconds to reach Mars and it takes 32 minutes to reach Jupiter and it takes 500 years to reach our Milky Way Galaxy. Light takes 2500000 years to go and reach the nearest Galaxy Andromeda and you will be surprised to hear that despite the speed of light, it can never cross the universe because our universe is spreading faster than light.
Time Dilation
What is time dilation? Let us understand in a very simplified way, you must have seen the Interstellar movie, in which time is extremely slow on the planet named Millers, where 1 hour spent is equal to 7 years spent on Earth. This is because the planet was very close to the black hole, according to Einstein's theory of relativity, black holes have more time warp, so that time slows down. So understand it in this way that it normally takes us time to go from point A to B, but if we pass near a black hole, then the curvature increases, so it takes more time for us to go from A to B.
Epsilon Eridani Star System
7th Aug 2000 Scientists have discovered a new star system named Epsilon Eridani in the Eridanus constellation about 10.5 light years away from Earth. This star system is exactly like our solar system. In this star system we have discovered Epsilon Eridani-b and a low mass planet Epsilon Eridani-c like Jupiter. Apart from this, the asteroid belt is also present in this star system just like our solar system. About 800 million years old, this star system is similar to the time when life began on our Earth. Scientists also consider this star system as the home of aliens.

PSR J1719 1438B
In the year 2009, MATHEW BAILES, who is an astrophysicist, saw a house from his telescope which was 3000 times bigger than the sun, yet it was revolving around its sun, then after research, it was found that in a supernova explosion, that star was transformed into a nevtron star, whose mass is much more than its house, so it is holding its star despite being small, and that planet has also become a super giant, but due to the heat of its star. Since then the carbon inside it has now become diamond and that planet is a complete diamond planet.
Center of Mass in Solar System
We all have been reading since childhood that all the planets in our solar system revolve around the Sun, so according to that, the middle point for all the planets should be the middle point of the Sun, but it is not so in reality. Gravitational force pulls the planet towards itself, similarly the planets also pull the Sun, but here the Sun is an ancient and very big star, so its force is more than all the other planets, hence all the planets are seen revolving around it, but all the planets And the center of mass between the Sun is different, like Jupiter is the largest planet in our solar system, so as soon as its gravitational force and the force of the Sun meet, both of them revolve around their center of mass which is away from the center of the Sun. Comes a little further.
Time Traveler Party
The great scientist Stephen Hawking was already experimenting on time travel. In 2009, Stephen Hawking hosted a reception for time travelers at the University of Cambridge. He sent out invitations but did not publicize the event until afterward. The idea was to see if any time travelers would attend, as they would be aware of the event's details through time-traveling knowledge. But no one attended that party which proved that humans cannot time travel. And we also know that if we have to go back in time then it is never possible in the universe.
What is Time?
Time!, what is time? You will say that a clock or a calendar will be something like this, no, time is not a thing, all these are things to measure time. Time is a dimension, I understand in simple language, time has been moving ever since our universe was created, so is time moving us? No, things keep changing with time, meaning motion also keeps on changing with time, see like ever since the universe was created, it is expanding and all this is happening with time. Before the Big Bang, there was no motion in the singularity, so there was no time then, it can be said as if only time can be the cause of change. Times are changing.
Why we should not make contact with aliens right now
Great scientist Stephen Hawking said that we should not make contact with aliens right now. Why did he give such advice? Because we humans are still like small children in the world of technology, you will say that science has progressed so much, so many discoveries have been made, we have even gone to space, once or twice in space. We do not become rich by leaving, we have not even searched for living on another planet or have gone to live on any other planet. This progress seems big to us but it is nothing. If we contact any alien civilization, they will reach our Earth and may even harm us, that is why even today we do not respond to any signal.
Quantum Elevator
What is a quantum elevator? Suppose you are in a building and each floor of this building is a different dimension, you live on the 4th floor, that is, in the 4th dimension, and you have to go from the 4th floor to the 10th floor and there is an elevator here which will take you there. But when you are going from 4th floor to 10th floor then you will not be able to see the floors coming in between and you will not even know what is on this floor. This is how the quantum elevator works. And this can be very different in different dimensions, it takes us in a fixed dimension.
Bennu Asteroid
-
Composition: Bennu is a carbonaceous asteroid, rich in carbon-based compounds. This composition makes it valuable for scientists, as it could provide insights into the origin of life and the early solar system.
-

Voyager's Golden Record
The Voyager Golden Record, a time capsule of humanity's cultural and scientific achievements, was launched aboard the Voyager 1 and Voyager 2 spacecraft by NASA in 1977. This phonograph record contains a diverse array of sounds and images representing Earth and its inhabitants, including greetings in 55 languages, music from various cultures, and images depicting life on our planet. The record was designed to serve as a message to any extraterrestrial civilizations that might encounter the Voyager spacecraft. A testament to human curiosity and creativity, the Voyager Golden Record remains a symbolic representation of our species' desire to reach out and connect with the unknown, even across the vastness of space.
WARP Drive
Warp drive is a theoretical propulsion system that features prominently in science fiction, notably in franchises like "Star Trek." The concept involves manipulating space-time to enable faster-than-light travel, allowing spacecraft to travel vast interstellar distances in a relatively short time. In essence, warp drive contracts space in front of the spacecraft while expanding it behind, creating a warp bubble that moves the vessel. While widely popularized, especially by theoretical physicist Miguel Alcubierre's theoretical framework in 1994, practical implementation remains a distant dream due to the enormous energy requirements and unresolved challenges in bending space-time as proposed. Scientists continue to explore the theoretical underpinnings of warp drive, but as of now, it remains firmly in the realm of speculative science fiction.
Psyche Asteroid
Psyche is a massive asteroid located in the asteroid belt between Mars and Jupiter. It's of particular interest to scientists because it's composed mostly of metallic iron and nickel, resembling Earth's core. This unique composition has led researchers to hypothesize that Psyche might be the exposed core of an early planetesimal, offering a rare opportunity to study the interior of a planet-like body. NASA's Psyche spacecraft, slated for launch in 2022, aims to explore this intriguing asteroid, providing valuable insights into the processes that shaped the early solar system and potentially uncovering secrets about planetary core formation.
Earendel Star
The James Webb Space Telescope has discovered the most distant star in space, which is believed to be the most distant star ever explored, and it is also believed that this star was formed only in the first 100 million years after the Big Bang. had gone Arandale was discovered by the Hubble Space Telescope in 2002 and along with its expansion, it has moved 2800 kilometers away from us. Recently, NASA has once again discovered this star with the help of James Webb Telescope and it has been revealed that it is 2 times bigger than our sun, its brightness is 1 million times more than our sun.
NGC 6166 Black Hole
