✨On June 28, 2009, Hawking threw a party for time travellers. The next day, he sent out the invitations. "Copies of it will survive in one form or another for many thousands of years," Hawking later said in the documentary "Into the Universe with Stephen Hawking."
"Maybe one day, someone living in the future will find the information and use a wormhole time machine to come back to my party, proving that time travel will, one day, be possible," he said✨

What is Entanglement in short?
#Part5🔭
✨Entanglement is a phenomenon in quantum mechanics where particles become correlated in such a way that their properties are intrinsically linked.
This allows for instantaneous correlations between particles separated by large distances, known as "spooky action at a distance." Entanglement is a key resource for quantum technologies, such as quantum computers and communication systems, and has led to new insights into the fundamental nature of reality in the quantum world.

❔Question❔ How can we experimentally demonstrate entanglement between two particles, and what are some of the methods used to quantify the degree of entanglement between them? Write your comment👇 💡Share: @AstroMechanics
Answer: Entanglement between two particles can be experimentally demonstrated using various methods such as the violation of Bell's inequality, quantum teleportation, and quantum state tomography. The degree of entanglement between the particles can be quantified using measures such as concurrence, entropy-based measures, and fidelity-based measures.
📌These measures provide a quantitative way to characterize the amount of entanglement between the particles and are useful for studying the properties and applications of entangled states in quantum information processing and other fields.

Black Holes, Wormholes and Time Machines
by Jim Al-Khalili
Do you know:
•What might happen if you fall into a black hole?
•That the Universe does not have an edge?
•That the reason it gets dark at night is proof of the Big Bang?
•That cosmic particles time-travel through the atmosphere defying death?
•That our past, present and future might all coexist "out there"?
With two remarkable ideas, Albert Einstein revolutionized our view of the Universe. Einstein showed how Spacetime is warped and stretched by the gravity of all objects in the Universe and even punctured by black holes. But such possible twisting of Spacetime allowed a magic not even Einstein could have imagined: time-travel.
Theoretical physicist Jim Al-Khalili finally lays science fiction to rest as he opens up Einstein's Universe.

What is a Condensed matter physics(Condmat)?
🔥Condensed matter physics, often abbreviated as "condmat," is the branch of physics that studies the physical properties of solids and liquids, particularly their electronic, magnetic, and optical properties.
It deals with the behavior of large groups of atoms or molecules and the interactions between them. Examples of condensed matter include metals, semiconductors, superconductors, and liquid crystals.
📌Condensed matter physics has many practical applications, such as the development of new materials for electronics and the study of the properties of materials used in energy generation and storage.

What are the classification of condmat?
It can be divided into several subfields based on the properties of the materials being studied and the techniques used to investigate them. These subfields include solid-state physics, soft condensed matter physics, materials science, surface and interface science, nanoscience and nanotechnology, and quantum condensed matter physics.
📌Each subfield focuses on different aspects of materials science, ranging from the properties of solids and liquids to the behavior of materials at the nanoscale and in extreme conditions such as low temperatures and strong magnetic fields.

Is time real or not?
✨The question of whether time is real is a philosophical and scientific one that has been debated for centuries. In physics, time is usually treated as a dimension, along with space, that is fundamental to our understanding of the universe. It is also intimately tied to the concept of change, as the passage of time is often associated with the occurrence of events and the evolution of physical systems.
However, some philosophers and physicists have argued that time may not be a fundamental aspect of reality but rather an emergent property of more basic physical processes. For example, some theories of quantum gravity suggest that time may be an illusion that arises from the entanglement of fundamental quantum states.
📌Ultimately, the question of whether time is real may not have a straightforward answer, and it may depend on the specific framework or perspective being used✨

Is time travel possible🕰🏃♂?
As far as current scientific understanding goes, time travel to the past is currently not possible using any known technology or scientific methods.
While time travel to the future is technically possible according to the theory of relativity, it would require traveling at extremely high speeds or being in the presence of extremely strong gravitational fields, both of which are beyond current technological capabilities.
There have been some proposed theoretical concepts for time travel, such as the idea of traversable wormholes or the use of time dilation via near-light-speed travel, but these ideas are still purely speculative and have not been experimentally validated.
📌It's worth noting that time travel is a topic of science fiction, and while it may be entertaining to imagine, it is important to distinguish between what is scientifically possible and what is purely fictional.

The ‘breath’ between atoms — a new building block for quantum technology
Breathing is a natural process found in living and non-living things. Even on the atomic level, there is a type of breathing called Mechanical vibration.
Recently, a University of Washington research team discovered that they could detect atomic "breathing" by observing the type of light atoms emit when stimulated by a laser. The team plans to use this discovery to encode and transmit quantum information and develop a new type of building block for quantum technologies. The quantum platform uses "optomechanics," where light and mechanical motions are coupled together, to control single photons running through integrated optical circuits for various applications. The team's findings were published in Nature Nanotechnology.

Light Years Facts⚡
✨Distance in space is very vast that the fastest thing in the universe, light, is used to measure them.
✨The speed of light is 300,000km/s.
✨The distance in space is so huge they are measured in light years- the distance light travels in a year.
✨A light-second is the distance that light travels in one second, 300 million meters.
✨A light year is the distance that light travels in one year, 9.46 trillion km.
✨Light years are one of the standard distance measurements in astronomy.
✨It takes about eight minutes for light from the sun to reach Earth.
✨Light takes 4.22 years to reach Earth from the sun's nearest star, Proxima Centauri. That means the star is 4.22 light years away- more than 40 trillion km.
✨Viewed from Earth Proxima Centauri looks like it was 4.22 years ago because its light takes 4.22 years to reach Earth.
✨Astronomers use Parsec to measure distances. They originally came from parallax shift measurement. A light year is 0.3066 parsecs.

Why does the Moon "follow" us when we drive?
As we rush down the road, we notice how everything flies past us in the opposite direction: trees, houses, fences, the road. And from the Moon, too, we expect it to fly past us, or at least go backwards the farther forward we go. When it doesn't, we feel as if it is "following" us.
The Moon may not seem to be very far away from us, but the average distance from it to Earth is 384,400 km. This enormous distance explains why, when we drive a car and look at the Moon, it seems as if it is following us.
Compared to the distance our car travels in a few minutes, this distance is enormous. So as we drive, the angle at which we see the moon remains virtually unchanged. And while everything flies past us, there is a sense that the Moon is "following" us.
