Are we living in flat or round shaped earth ?

As we all have a different mindsets , similarity we believe on different inferences to arrive us at a conclusion that we assume to be true ,possibly in our perspectives .But this would rather leads to different conclusions for specific things , disagreement would follow at last. It's obviously known that we won't go to something better with out agreement.So everyone should have facts that's acceptable every where unlike of myth.

As far as we concerned there's still myth acceptable , specially by uneducated society , although science is what matters and which provides plausible knowledge about our universe.


Are we living in a flat earth or spherical shaped earth ?

Aristotle , a Greek philosopher concerned with these two good arguments for believing that the Earth was a round ball rather than a flat plate. First, he realized that eclipses of the moon were caused by the Earth coming between the sun and the moon. The Earth’s shadow on the moon was always round, which would be true only if the Earth was spherical. If the Earth had been a flat disk, the shadow would have been elongated and elliptical, unless the eclipse always occurred at a time when the sun was directly above the center of the disk.


Second ,Greeks knew from their travels that the Pole Star appeared lower in the sky when viewed in the south than it did in more northerly regions. From the difference in the apparent position of the Pole Star in Egypt and Greece, Aristotle even quoted an estimate that the distance around the Earth was four hundred thousand stadia. It is not known exactly what length a stadium was, but it may have been about two hundred yards. This would make
Aristotle’s estimate about twice the currently accepted figure.

They also have third reason not to believe earth as flat plate. "For why
else does one first see the sails of a ship coming over the horizon and only later
see the hull?"

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.
