Why does steady state universe theory lost it's acceptance?

it's experimental evaluation,some signals received have strength where as some of them are weaker comparably ,the more attractive fact about it is that the weaker ,that received from farther distance are observed to be more in number ,than those received from nearby .

This creates irregularities in the trend and therefore ,opposes the idea , universe looks the same from every side.

Quantum Tunneling


Let's take you to a quantum world ,and see one of the quantum phenomenon

⚛According to classical physics theories, it is a quantum phenomenon that occurs as particles pass through a barrier that should be difficult to pass through. A physically impenetrable medium, such as an insulator or a vacuum, or a region of high potential energy, may serve as a barrier.

⚛A particle with insufficient energy will not be able to overcome a potential obstacle in classical mechanics. However, in the quantum universe, particles often behave like waves. A quantum wave will not abruptly stop when it hits a barrier;
instead, its amplitude will decrease exponentially.

⚛The probability of finding a particle in the deeper end of the barrier decreases as the amplitude decreases. If the barrier is thin enough, the amplitude on the other side can be non-zero. This will mean that any of the particles have a finite chance of tunneling through the barrier.

⚛The current density ratio from the barrier divided by the current density incident on the barrier is the tunneling current. There is a finite chance of a particle tunneling through the barrier if this propagation coefficient is non-zero

So are you interested if some facts about this explained in article form ?

📚 Are we reason for existence of universe?
"We are not the reason for the existence of the universe, but our ability for self-awareness
and reflection makes us special within it."

#Meta_materials

What are these metamaterials?


⚛ They are substances that have optical properties not found in nature. Metamaterials are created by em￾bedding tiny implants within a substance that force electromagnetic
waves to bend in unorthodox ways.

⚛ At Duke University, scientists em￾bedded tiny electrical circuits within copper bands that are arranged in flat, concentric circles (somewhat resembling the coils of an electric oven). The result was a sophisticated mixture of ceramic, Teflon, fiber composites, and metal components.

⚛These tiny implants in the copper make it possible to bend and channel the path of microwave radiation in a specific way. Think about the way a river flows around a boulder. Because the water quickly wraps around the boulder, the presence of the boulder has been washed out downstream.

⚛ Similarly, metamaterials can continuously alter and bend the path of microwaves so that they flow around a cylinder, for example, essentially making every￾thing inside the cylinder invisible to microwaves. If the metamaterial can eliminate all reflection and shadows, then it can render an object totally invisible to that form of radiation.

What's cryptocurrency

🔰It's a digital currency in which transaction are verified and records are maintained by decentralized system using #cryptography




What's #cryptography?

🔰It's construction and analysis protocol that prevent third parties(public) from reading private messages.

👉It's a synonymous with #encryption

#encryption is conversion of info from readable state to apparently nonsense.

So what's advantage of cryptocurrency?

🔰Decentralized cryptocurrencies like Bitcoin now provide outlet for personal wealth that's beyond restriction and confiscation.

You may raise a question is Bitcoin and cryptocurrency the same ?🤔

The answer is 👇

🔰 Bitcoin is the name of best known cryptocurrency, the one for which Blockchain technology was invented.

Is cryptocurrency a medium of exchange ?

🔰yes of course! It is , cryptocurrency is the same as USD except it's digital and uses encryption technologies to control the creation of monitory units and to verify the transfer funds.

🧠who is the owner of Bitcoin?

🔰Satoshi Nakamoto is #pseudonym. ...(I don't exactly know the meaning of it🤫) for the person or people who helped develop the first Bitcoin software and introduced the concept of cryptocurrency to world by 2008 paper
He remained active in the creation of Bitcoin and Blockchain until 2010 buy hasn't been heard from since.


🔰Is cryptocurrency illegal?
Id you're wondering whether Bitcoin mining is legal,the answer is yes in most cases

🔰However ,countries like

Algeria
Bangladesh
China
Egypt
Iraq
Morocco
Nepal
Qatar and
Tunisia outlawed Bitcoin mining (source law library of Congress report)

How many Bitcoins are left ?

🔰By June 2022 ,there are about 2M Bitcoins left to be mine , which means that there are nearly 19M currently in existence.

#bitcoin_gained_popularity_cause_of_its_unique_design_and_underlying_technology.

(last but not the least)

Can I mine BTC on my phone?

🔰It's possible to mine BTC on smartphone, both on Android or iphone .Phones are computers,and any computer can be set to task of computing hashes .A hash is a one way of transforming data .


Finally

🔗Helpful hint:Trust wallet is a mobile app used to save these cryptocurrency on.

#What_do_we_mean_by_evolution? (Part 1)
Lemme start with definition my friend gave and I liked.

🔰He started saying ,"whatever it is evolution is a change, even a little deviations in physical and mental build up from our primates is considered as evolution." he continued saying, "these little changes may seem trivial but they add up for millions of years to look significant."

According to Oxford English dictionary 👇👏

✍"It's process by which different kinds of living Organisms are believed to have developed from earlier forms during the history of the earth ".  Or shortly "It's gradual development of something "

🔰Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction. Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.(To be continued)

Is evolution theory or fact?(part 2)

🔰Evolution is a theory.It is not a scientific fact or law.Many people learned in elementary school that a theory falls in the middle of a hierarchy of certainty-above a mere hypothesis but below a law.Scientists do not use the terms that way , however.

Do all life on earth shares same ancestor ?

🔰The answer is yes! LUCA that lived approximately 3.5-3.8 Billion years ago .The fossil record includes a progression from early biogenic graphite , to microbial mat fossils to fossilised multicellular organisms.

Note- existing patterns of biodiversity have been shaped by repeated formations of new species (speciation) throughout the evolutionary history of life on Earth . Morphological and biochemical traits are more similar amon species that share more recent common ancestor,and can be used to reconstruct phylogenetic trees.

THE NEXT IS QUESTION OF YOU ALL

What's the evidence for evolution?

Five basic evidences are 👇

1.ancient organisms remain
2.Fossil layers
3.similarities among organisms that are alive today
4.DNA simalarities
5.similarities of Embryo

What's importance of evolution?

🔰These evolution have led to major improvements in living standards ,public welfare,health and security.They have changed how we view the universe and how we think about ourselves in relation to the world around us . Biological evolution is one of the most important ideas of modern science.

🔰Their discoveries have influenced not just the development of biology but numerous other scientific and industrial fields, including agriculture, medicine, and computer science.

Upcoming (part 3)

After evolution I'll be dealing with topic on the poll accordingly

#Who_discovered_evolution? (Part three)

🔰Charles Darwin is commonly cited as the person who "discovered" evolution.But,. the historical record shows that roughly seventy different individuals pubished work on the topic of evolution between 1748 and 1859 ,the year that Darwin published on the origin of species.

🔰The theory of evolution by natural selection was conceived independently by Charles Darwin and Alfred Russel Wallace in the mid-19th century and was set out in detail in Darwin's book On the Origin of Species.

🔰Evolution by natural selection was first demonstrated by the observation that more offspring are often produced than can possibly survive. This is followed by three observable facts about living organisms:

(1) traits vary among individuals with respect to their morphology, physiology and behaviour (phenotypic variation),
(2) different traits confer different rates of survival and reproduction (differential fitness) and
