Another alternate reality:

And [God] said, “Who told you that you were naked? Have you eaten from the tree that I commanded you not to eat from?”

The man said, “The woman you put here with me—she gave me some fruit from the tree, and I ate it.”

Then the Lord God said to the woman, “What is this you have done?”

The woman said, “The serpent deceived me, and I ate.”

"It's my fault", said the Lord God. "I shouldn't have given the serpent the power of speech. And for what purpose did I even create that tree?"

Quantum tunneling is a phenomenon in the quantum world whereby sub atomic particles pass through barriers forbidden to be passed through by classical physics .


A way to conceptualize this is to imagine a ball and a hill. In classical physics for the ball to get to the top of the hill it needs sufficient energy . if it doesnt have this amount of energy , it cant reach the hill top .

But in quantum mechanics , the ball with a very small probability , can reach the top of the hill without having this sufficient amount of energy.


This effect was predicted in the early 20th century but ots acceptance came in the mid century.

This is due to the wave particle duality of matter and is explained using Heisenberg s principle of uncertainty ( position and momentum of a particle cant be measured with perfect certainty simultaneously.


Quantum tunneling is highly probabilistic . through the schodinger equation we can calculate the probability for a particle to observe quantum tunneling.


As a particle approaches a barrier it is described by its wave function. The square of the wave function gives us the probability of finding a particle at a particular point at a particular time.


QUANTUM TUNNELING IN NATURE


Without quantum tunneling , fusion in the sun would not be able to occur as the temperature of the sun is barely enough to overcome nuclear repulsion but with quantum tunneling. . By virtue of quantum tunnelling and Heisenberg’s uncertainty principle, the protons can “tunnel” through the barrier even given the apparently insufficient temperature and energy.

HardMirror:
It is so obvious you don't read. Marvel and DC comics has been predicting and describing future technologies for over 60 years now. Depicting touchscreen gadgets, holographic keyboard that apple just released just 2years ago, the samsung gear (virtual reality visors), the oculus are all things sci-fi authors had been writing about accurately describing how they will look and work.
Why can't the bible authors describe future technologies? Book is book. When John wrote that books were opened, he meant their paper books, let us stop trying to add to the very straight forward writings of the bible and koran.

If what he saw was a tablet he would not have said books where brought out and opened.

Well deceive yourself all you want, we all know the truth and only a person without common sense will fail to understand simple things written in the bible.

Give humans another 20years and tablets would be out dated. There are 1terrabyte memory cards now. So I wonder why heaven has to be parking books when they shld be far ahead of us humans. When they can save trillions of data on a device not bigger than 4grains of rice.

Physicists Slow Speed of Light


By William J. Cromie

Gazette Staff


Lene Hau has shed new light on a new form of matter. Photo by MaryAnn Nilsson.
Light, which normally travels the 240,000 miles from the Moon to Earth in less than two seconds, has been slowed to the speed of a minivan in rush-hour traffic -- 38 miles an hour.

An entirely new state of matter, first observed four years ago, has made this possible. When atoms become packed super-closely together at super-low temperatures and super-high vacuum, they lose their identity as individual particles and act like a single super- atom with characteristics similar to a laser.

Such an exotic medium can be engineered to slow a light beam 20 million-fold from 186,282 miles a second to a pokey 38 miles an hour.

"In this odd state of matter, light takes on a more human dimension; you can almost touch it," says Lene Hau, a Harvard University physicist.

Hau led a team of scientists who did this experiment at the Rowland Institute for Science, a private, nonprofit research facility in Cambridge, Mass., endowed by Edwin Land, the inventor of instant photography.

In the future, slowing light could have a number of practical consequences, including the potential to send data, sound, and pictures in less space and with less power. Also, the results obtained by Hau's experiment might be used to create new types of laser projection systems and night vision cameras with power requirements a million times less than what is presently possible.

But that's not why Hau, a research scientist at both Harvard and the Rowland Institute, originally set out to do the experiments. "We did them because we are curious about this new state of matter," she says. "We wanted to understand it, to discover all the things that can be done with it."

It took Hau and three colleagues several years to make a container of the new matter. Then followed a series of 27-hour-long trial runs to get all the parts and parameters working together.

"So many things have to go right," Hau comments. "But the results finally exceeded our expectations. It's fascinating to see a beam of light almost come to a standstill."


Lene Hau, Zachary Dutton, and Cyrus Behroozi (from left to right) stand by the equipment they used to create the ultra-high vacuum and super-low temperatures with which they slowed down pulses of light. The process also compresses the pulses from 2,500 feet to 0.002 inches in length. Photo by MaryAnn Nilsson.
Members of Hau's team included Harvard graduate students Zachary Dutton and Cyrus Behroozi. Steve Harris from Stanford University served as a long-distance collaborator.

Making a Super-atomic Cloud

The idea of this new kind of matter was first proposed in 1924 by Albert Einstein and Satyendra Nath Bose, an Indian physicist. According to their theory, atoms crowded close enough in ultra-low temperatures would lock together to form what Hau calls "a single glob of solid matter which can produce waves that behave like radio waves."

This so-called Bose-Einstein condensate was not actually made until 1995, because the right technological pot to cook it up in did not exist. Vacuums hundreds of trillions of times lower than the pressure of air at Earth's surface, and temperatures almost a billion times colder that that in interstellar space, are needed to produce the condensate. Temperatures must be lowered to within a few billionths of a degree of absolute zero (minus 459.7 degrees F), where atoms have the least possible energy and all but cease to move around.

Hau and her group started with a beam of sodium atoms injected into a vacuum chamber and moving at speeds of more than a thousand miles an hour. These hot atoms have an orange glow, like sodium highway and street lights.

Laser beams moving at the normal speed of light collide with the atoms. As the atoms absorb particles of light (photons), they slow down. The laser light also orders their random movement so they move in only one direction.

When the atoms are slowed to a modest 100 miles an hour or so, the experimenters load the atoms into what they call "optical molasses," a web of more laser beams. Each time an atom collides with a photon it is knocked back in the direction from which it came, further slowing it down, or cooling it.

The atoms are now densely packed in a cigar-shaped clump kept floating free of the walls of their container by powerful magnetic fields.

"It's nifty to look into the chamber and see the clump of cold atoms floating there," Hau remarks.

In the final stage, known as "evaporative cooling," atoms still too hot or energetic are kicked out of the magnetic field.

The stage is now set for slowing light. One laser is shot across the width of the cloud of condensate. This controls the speed of a second pulsed laser beam shot along the length of the cloud. The first laser sets up a "quantum interference" such that the moving light beams of the second laser interfere with each other. When everything is set up just right, the light can be slowed by a factor of 20 million.

The process is described in detail in the Feb. 18 issue of the scientific journal Nature. (Warning: Don't try this at home.)

Relativity and the Internet

Slowing light this way doesn't violate any principle of physics. Einstein's theory of relativity places an upper, but not lower, limit on the speed of light.

According to relativity theory, an astronaut traveling at close to the speed of light will not get old as fast as those she leaves behind on Earth. But driving at 38 miles an hour, as everyone knows, will not affect anyone's rate of aging.

"However, slowing light can certainly help our understanding of the bizarre state of matter of a Bose-Einstein condensate," Hau points out.

And a system that changes light speed by a factor of 20 million might be used to improve communication. It can be used to greatly reduce noise, which allows all types of information to be transmitted more efficiently. Also, optical switches controlled by low intensity light could cut power requirements a million-fold compared to switches now operating everything from telephone equipment to supercomputers.

But what about the cost and exotic equipment needed for such improvements? "Technologies that push past old limits are always expensive and impractical to begin with; then they become cheaper and more manageable," Hau says matter-of-factly. She sees the possibility that slow light will lead to "significant advances in communications ten years from now, if we get to work on it right away."

What will she do next?

Hau sweeps her hand over a roomful of equipment and explains how things are already being set up to slow light speed even more, to one centimeter (less than a half-inch) a second. That's a leisurely 120 feet an hour.

Hau will give a lecture on her experiments at 4:30 p.m. on Monday, Feb. 22, at Room 250, Jefferson Laboratories.

Teempakguy:
Isn't matter a form of energy with less entropy?

If this is so, won't converting energy into matter violate the laws of thermodynamics? notably reducing the entropy of the universe?

I have to confess, I've never actually considered the possibility of converting energy to matter, never could find a use for it.

Energy cant be said to have entropy because entropy itself is a mathematical function of the energy of a system.

LadyAngel22:
Hello I am new to this thread.

Please no negative comments.

I have spoken wrongly about a person who i thought was helping me and they were actually monitoring me. Please what do i do because the person is offended with me and i and my family have been getting serious witchcraft attacks. things planted in my body and evil arrows fired into my body. I have been praying and praying for deliverance but the attack is getting worst. He have also put me in an evil covenant which i have tried to get out and if i tried to leave he will attack my loved ones. the person is also using witchcraft to attack my loved ones by shooting evil arrows of accident and sickness. Please advice what i should do.

Thanks
Lady Angel

Lmao and xtians say jesus gives peace of mind . i laugh in arabic.
Evil arrows indeed , may be na oliver queen dey fire am

Everything all started about 2 years ago when i was in ss3 . i had a very close friend , who was so nice , kind and a person who was always there for me .

Sha , months later , he then told me that he wasnt a xtian nor a muslim, but a goddian . trust xtians na , immediately i startted telling him that he would go to hell if he doesnt believe in jesus.

He asked me questions about religion . he asked me how i was so sure that jesus was the son of god and all that and all that . i told him that it was because of jesus fulfilled prophecies ( how gullible i was ).

I told him he did not want to believe in jesus christ because he just wanted to sin .


I even started to dislike him because of his disbelief in jesus. It caused problems for our friendship.

I asked him what i would do to make him believe . he told me to show him why he should chose christianity rather than other religions

Then i decided that i would dedicate my whole time to searching for scientific proof that the bible is right , historical proof , prophecy fulfilment , and most importantly why he should not choose a religion like islam.


I then started to search for scientific and historical errors in the koran . and issues of violence . i had a good laff and i wondered why any sane person would chose to believe things like that.


Later on , i started finding faults with issues like the trinity , speaking in tongues , etc.

I later discovered that the bible had errors more foolish than those in the koran ,


But a swell idea poped in my mind, i told myself to just inteprete those errors as being figurative ( like kingebukas blog) but i realised that if those errors would have to be figurative , the quranic errors would have to be symbolic as well .


My eyes began to open to other issies such as interdenominational doctrinal conflicts , fraudulent prophecies , christs false prediction of his coming ., yahwehs phobia to iron chariots , god punishing an isrealite who dared to make the priests kind of ointment , the talking donkey , the young earth view , the ridiculousness of a global flood, ezekiel false embarassing prophecy ob the destruction of tyre ( which he himself admitted was false ) ., cobtradixtons in the life of jesus , new testament authors taking prophecies out of context , etc .

With all this , i knew christianity and the bible were nothing but tales by moonlight

I then decided to adopt god believing , which then led to deism, which led to pantheism , and which finally led to agnostic atheism.



Sorry for the long story


My plan to convert my friend back fired against me .

Lmao . rotflol. Mofo o

Seun:
God created the first human couple and placed them in a garden with a talking snake and a tree that they were never to eat from. The talking snake convinced them to eat from the tree. For this, God cursed them and all human babies that would ever be born. Centuries later, God made a pact with a small tribe of shepherds in the desert - the jews. He would be their God if they followed his very strict laws.

God was surprised that the jewish pact didn't cause God to forgive all human beings, so thousands of years later, God prepared a new plan. God would impregnate a virgin, and she would give birth to God. God would grow up to be crucified for calling himself the Son of God. God's brutal murder by humanity would pay for humanity's sins against God. Then God would rise again after 3 days but only appear privately to his followers, proving that God was indeed the Son of God. Then God would chill for 30 days as God's followers met in a closed room, and afterwards God would descend on them in little flames of fire and cause them to preach God's good news in many languages.

Because of God's sacrifice, God would forgive any person who believed that God died for humanity's sins against God. After death, God would send the believers to a place where they would spend all eternity telling God how awesome he is. God would throw those who didn't believe this story or were not told about it into a lake of fire where they would be burnt alive for all eternity, demonstrating God's justice and love.

In an alternate reality, God said, "I'm angry that you ate from the tree". Adam and Eve said, "sorry sir". God said, "ok I forgive you". The end.

Lmao .

Mo fo o .

Nice one op .

P. S . the alternate reality is in the koran , as allah forgave adam and eve for their crime

Einstein's theory of special relativity states that mass and energy are interconvertible . we know of mass being converted with energy as in the case of nuclear bombs , but what we may not be to familiar with is that the reverse is also possible .


Pair production


Pair production is the conversion of photons to an elementary particle and its anti particle .

For example , photon to electron and positron.

Photons are chargeless , hence , they produce both a positive and a negative particle .

0 = + 1 - 1

The photons must be close to an atomic nucleus for this process to occur

The reason is that pair production can t happen in a vacuum is that the law of conservation of energy and the law of conservation of momentum can not be conserved silmutaneously .


Law of conservation of energy.


Energy of photon=energy of positeron + energy of electron + kinetic energy of electron + kinetic energy of positeron



Law of conservation of momentum.


Momentum of photon = momentum of electron + momentum of positeron


Hf / c = mv1 + mv2

Where v1 = velocity of elecyron

Where v2 = velocity of positeron

Hf = mc ( v1 + v2 )


But we know hf = 2mc^2 from the first equation

E = hf E = mc ^ 2

But v1 is not equal to c .

And v2 can never be equal to c.

Remember that elementary particles only move at a velocity which is never equal to speed of light.

Therefore an obstacle would have to absorb a large part of the momentum so that the laws of conservation of energy and momentum can be satisfied simultaneously.



Such an obstacle is the atomic nucleus.


But anyway the energy of the photons has to exceed the total resting mass energies of both electrons and positrons

Omo, na yam and akara I see buy this afternoon o, when all the bread sellers close their shop go church(as if say I like eating bread sef ) Foodstuff dey house, na me just lazy to cook. Abeg how many days remain for the money I kept in my bank to dry up there?

Lol. U know say u still dey owe me credit

16 days left for otem to hussle for bread

Otem , how far naw , u don see bread chop

Chrisx1x:
i never knew you were an atheist until now.i just pray you don't find yourself in a very tight situation someday where the only thing left is to hope for the impossible-a miracle.believe it or not,faith works.

Very tight situations are no respecters of religion anf overcoming those tight situations is not a trend exclusive to christians alone

sonOfLucifer:
Your post has more color than sense. I pity you. Honestly.

Baba u heartless die

johnydon22:
Its mostly sad when you don't really understand the scientific thesis you used...

there is another thing i noticed that is laughable, theists open threads trying hard to reconcile scientific facts with their religious texts.

you see threads like 'Science agrees with the bible' where they try hard to reinterpret religious texts to mean what they want.

when you open such a thread you'll still see a situation when evolution comes up, the same person who opened the thread will be the same to say science is nonsensical and irrational propelled by the devil..

outrightly deny and talk down on the same science you are begging to agree with your religious texts.

it's hilarious

most of these arguments are based on emotions and gut feelings rather than intellectual curiosity and honesty

For example ,


They say " let there be light " in the book of genesis is an obvious proof that moses knew about the big bang , but what they do not know is that for hundreds of thousands of years after the big bang the universe was devoid of a single photon of light . and they confuse the big bang to mean an explosion of some sort .



The kind of tight spots christians put themselves in when they try to use science to prove primitive myths as the truth.

Dejideji1:
Bro you didn't get my point., if you call yourself an Atheist here in Nigeria, you are automatically saying that you DO NOT believe in the existence of God without any doubt.

Nobody will be patient enough to know if you are Gnostic or Agnostic Atheist. Check her comment again, she was arguing from the Agnostic Atheist point of view yet she chose to say "Atheist". How am i to know if she is Gnostic or Agnostic?

Only two guys here have confessed they are agnostic. That was why i faulted her. As a science student you must be clear and concise.

Lol , did we steal meat from pot

johnydon22:
No vex, i am quite enjoying this too

It was way cool when u typed in italics , although it was a lil bit difficult to read

johnydon22:
One mod like that chop me ban on top that bold italics matter

Why ? wot nonsense

sonOfLucifer:
Aah.. me intelligent? tankyu o..

Seun.. any chance of fp? Lalasticlala dey fear Satan..

This lalasticlala no dey pity sef

sonOfLucifer:
Aah.. me intelligent? tankyu o..

Seun.. any chance of fp? Lalasticlala dey fear Satan..

Lol.

Disown lucifer as your father and u will make fp.

Johnny , why have u stopped writing in italics , just curious

johnydon22:
LOL People always misunderstand and ultimately misrepresent the atheist position..

There is one thing i noticed on Nairaland lately there are more threads with "atheist/atheism" on their topics than there are now ones with 'God, religion'..

Thats really curious!!!

I swear.

Even those topics on bible blunders no dey reign again like b4

johnydon22:
Exactly!!! i'm sorry but i have gone past the stage of engaging in such meaningless mostly[b] egoistic infantilebsquabbles...[/b]

Did you notice the difference between this and the Cosmological and Philosophical forum, the difference is the level of minds on them.

Choiii . Omo see as u just dey tear grammar. Ah . ah . only u .

Dejideji1:
Really? I have always seen you as one of the most radical Atheists here on NL. But still second to johnydon22 any way.
That guy is the most radical Atheist here on NL and very intelligent too. he must be Gnostic. Call him and HardMirror to view this thread cos i know you are friends.

Lol. .

Johnny is not gnostic o. He is also agnostic.


Johnny and hardmirror , come and see o.
