Os Dias

 

É difícil explicar essa ‘coisa’ chamada dia. Qual é o verdadeiro significado dos dias? Sempre me pego questionando isso. Qual é o verdadeiro significado ou o porque de estarmos aqui, vivendo em dias em que as coisas não andam muito bem. Não falo só por mim, falo pelo mundo todo, qual o verdadeiro significado de existirem dias de guerras, ou melhor, porque existem?

Acredito que o ser humano esta se auto-destruindo,mas não tem conhecimento disso, são inúmeras as catástrofes que ja aconteceram, acontecem e ainda vão acontecer. Mas o porque de tudo isso?

Dias em que crianças sofrem sem terem culpa nenhuma de nada, crianças que sofrem, passam fome, sofrem com as guerras em seus países. Qual, ou o porque disso?

Porque somos assim? Gostamos de nos auto-destruir? Não seria melhor se vivêssemos todos em paz, se aceitássemos que apesar de sermos feitos da mesma matéria, nem todas as pessoas são iguais e pensam iguais.

São muitas as pessoas do mundo todo que lutam pela paz mundial, mas a maioria estão conectadas com as coisas ruins, que não querem isso. Pessoas que se reunem para meditar e pedir a paz mundial. Você pode assistir um dia um video chamado “ Uma mensagem de esperança “ ou “ A message of hope”.

Aqui esta uma parte.

 

Assista e reflita sobre o que estamos transformando nossa casa, e que é sim possível transformamos nossa casa em um lugar aonde só exista o amor, porque é ele, o amor que é capaz de transformar tudo, no matter what.

Estudo aponta que crença em extraterrestres e crenças religiosas compartilham uma motivação psicológica semelhante

Uma nova pesquisa sugere que crenças paranormais sobre a inteligência extraterrestre estão ligadas à necessidade de encontrar sentido na vida.

O estudo com 1.146 alunos de graduação examinou a motivação psicológica por trás da crença de que objetos voadores não identificados (OVNIs) são naves espaciais de outros mundos, e que o governo tem evidências de inteligência extraterrestre, mas que está encobrindo-as.

O estudo concluiu que essas crenças paranormais sobre alienígenas foram parcialmente motivadas pela necessidade de atribuir sentido. A falta de sentido e um desejo de encontrá-lo estavam ligadas a uma maior parte na crença em extraterrestres, e experimentalmente aumentando a necessidade de sentido aumenta a chance da crença paranormal em extraterrestres. O estudo também relevou que ateus e agnósticos tendem a acreditar em extraterrestres, e que isso foi, por sua vez, associado com a falta de sentido.

O estudo foi publicado online e revisado por pares na revista científica Motivation and Emotion no dia 06 de março de 2017.

Luz coerente….

Desde que  adquiri o uso da razão , minha inclinação para o saber tem sido tão forte e violenta que nem as censuras de outras pessoas […] nem minhas próprias reflexões […] têm sido capazes de deter esse impulso natural que Deus me dotou. Somente ele deve saber o por quê; e Ele sabe também que Lhe tenho suplicado que tire a luz do meu entendimento, deixando-me apenas o suficiente para seguir sua lei; pois qualquer coisa além disso é excessiva numa mulher, segundo  certas pessoas. E outras dizem mesmo que é nocivo.

Carl sagan : Contato

O grande destaque de Contato é que a especulação tem uma profunda base científica. Carl Sagan apresenta conceitos de radioastronomia e o potencial dessa área da Astronomia para procurar vida inteligente em outros sistemas estelares. Esse é o tema científico cental da obra, mas Sagan também explorou muito sobre o relacionamento humano.

A personagem principal é Ellie. Sua história é contada desde a infância, quando menina mostrava enorme interesse nas questões do Cosmos. Seu pai a incentivava nesse interesse, e como resultado ela era uma criança bem diferente das outras. Sua vida pessoal muda quando o pai morre e a mãe casa-se com um homem machista. Apesar dos obstáculos impostos pelo seu padrasto, que a desmotivava muito com seu discurso machista, Ellie conseguiu entrar na faculdade, tornou-se uma importante pesquisadora na área de radioastronomia e especializou-se na busca de vida inteligente.

Sagan descreve toda trajetória acadêmica de Ellie. Então quem é da academia certamente vai se identificar em muitos momentos. Sagan é sensível e fala da dificuldade que Ellie tem de se encaixar, fala dos rapazes da academia que não sabem se relacionar bem. Ela acaba inclusive namorando um músico, provavelmente porque todos os seus colegas da academia não sabem flertar e não são interessantes para um relacionamento amoroso. Adoro essa parte do livro, pois é uma “virada de mesa” nas questões de relacionamento.

A trajetória de Ellie é contada desde a graduação até quando se torna diretora de um importante centro de pesquisas. Quando um sinal anômalo é recebido pelos radiotelescópios, Ellie acaba liderando uma equipe para monitorá-lo e decifra-lo. E aí entram as questõres relacionadas com opinião pública (muita gente acha que muito dinheiro está sendo gasto) e com interesses políticos e estratégicos, já que na obra, o mundo continua polarizado (URSS x EUA).

Ellie acaba se relacionando com políticos, tendo contato com pesquisadores do mundo todo em congressos (Sagan descreve os congressos científicos com muita fidelidade). Ao longo das discussões, fundamentalistas religiosos se envolvem no assunto e reinvidicam o direito de saber o que está acontecendo. O livro faz um interessante debate de Ciência x Religião, revelando que a oratória e o discurso de um líder religioso pode ser muito mais sedutor do que o discurso científico (e como sabemos disso, infelizmente). Só que Sagan não é Dawkins: ponderado, na obra é possível perceber que ele dá uma importância a experiência religiosa e diria que isso tem tudo a ver com a experiência queé o ápice da história.

O livro foi adaptado para o cinema em 1997, com Jodie Foster no papel principal. Dirigido por Robert Zemeckis, conta também com Matthew MaConaughey (de Interstellar).  A propósito, Interstellar tem muito de Contato: possui uma base científica, mas também apela para o sentimental e fantástico.

The Truth Behind Einstein’s Letter on the ‘Universal Force’ of Love

One of the greatest things about discovering something new is the path it leads us down and doors it opens into new insights and findings that we otherwise might have never known. An article we read leads us to a new author or book. A conversation we have leaves us “googling” something or someone we’ve never heard. A segment on the radio inspires us to learn more about a business or topic being discussed.

Or, as most recently happened to me, a letter circulating via social media leads to the debunking of a myth surrounding its alleged author.

Perhaps you’ve read it: Albert Einstein’s letter to his daughter Lieserl regarding the “universal force” of love. It’s a beautiful read, offering a universal message that speaks to the essence of the human condition and our incessant yearning to believe in love’s conquering force.

That such sentiments were seemingly written by Albert Einstein, the most revolutionary scientist of the 20th century, only solidified its potency and widespread appeal — hence it going viral on social media.

But, as we’ve been forced to learn in our rapidly expanding digital age, you can’t always trust what you read on the Internet, particularly when it lacks an original source, as was the case with this supposed letter from Einstein.

Struck by its beauty, however, I began researching its origins in hopes that it would confirm Einstein as the author and give way to a post about the unlikely musings on love from one of the world’s most brilliant scientists.
What I discovered, however, was a heap of controversy pointing to the fabrication of a letter falsely attributed to Einstein in an attempt to legitimize its words and message.

The preface of the letter explains that Einstein’s daughter, Lieserl, donated 1,400 of his letters in the late 1980s to the Hebrew University with orders not to publish their contents until two decades after his death; this letter on the “universal force” of love was supposedly one of them.

Interestingly, however, further research indicated that Lieserl herself might not be the most reliable source, given that very little is known about her. In fact, her existence was largely unknown to biographers until 1986 when a batch of letters from 1897-1903 between Einstein and his first wife, Mileva Maric, were discovered by his granddaughter Evelyn (in which Einstein mentions Lieserl; these letters were published in the book The Love Letters in 1992).

Furthermore, a 1999 book by Michele Zackheim, Einstein’s Daughter: The Search for Lieserl, argued that Lieserl was born with a mental handicap and died of scarlet fever in 1903 when she was nearly two years old (Lieserl was mentioned for the last known time in a letter from Einstein to Mileva on September 19, 1903). Others, however, have maintained that she was put up for adoption.

After a search in Hebrew University’s online archives (which houses the Albert Einstein Archives) and the Collected Papers of Albert Einstein failed to yield any results, I was nearly convinced that the letter was, indeed, fabricated.

But, before resting the case, I turned to Diana Kormos-Buchwald, a professor of physics and the history of science at the California Institute of Technology (Caltech), whose name I happened to come across in an article in the New York Times while researching the letter.

As director and editor of the Einstein Papers Project – which just last December launched The Digital Einstein Papers, making 5,000 documents spanning Einstein’s first 44 years of his life available online – surely Dr. Kormos-Buchwald would be able to provide some clarification regarding the authenticity of this letter.

Her response?

“This document is not by Einstein. The family letters donated to the Hebrew University – referred to in this rumor – were not given by Lieserl. They were given by Margot Einstein, who was Albert Einstein’s stepdaughter. Many of those letters were published in Volume 10 of The Collected Papers of Albert Einstein in 2006 and in subsequent volumes, in chronological order.”

As disappointing as it was to learn that Einstein didn’t pen the letter, it was equally exciting to discover a plethora of documents I hadn’t even known existed. What became a fervent search for validation evolved into an utter fascination by some of Einstein’s authentic writings, many of which are, in fact, written to family members, friends and colleagues.

While the question of who is behind the “universal force” of love letter still remains a mystery, part of the truth has been revealed – and that is what seems most important. That we always remember and strive to seek the truth in all things. That we not shy away from asking questions and challenging notions. That we remain curious.

As Einstein himself once said, “The important thing is not to stop questioning. Curiosity has its own reason for existing.”

Here is the letter:

“When I proposed the theory of relativity, very few understood me, and what I will reveal now to transmit to mankind will also collide with the misunderstanding and prejudice in the world.

I ask you to guard the letters as long as necessary, years, decades, until society is advanced enough to accept what I will explain below.

There is an extremely powerful force that, so far, science has not found a formal explanation to. It is a force that includes and governs all others, and is even behind any phenomenon operating in the universe and has not yet been identified by us. This universal force is LOVE.
When scientists looked for a unified theory of the universe they forgot the most powerful unseen force. Love is Light, that enlightens those who give and receive it. Love is gravity, because it makes some people feel attracted to others. Love is power, because it multiplies the best we have, and allows humanity not to be extinguished in their blind selfishness. Love unfolds and reveals. For love we live and die. Love is God and God is Love.

This force explains everything and gives meaning to life. This is the variable that we have ignored for too long, maybe because we are afraid of love because it is the only energy in the universe that man has not learned to drive at will.

To give visibility to love, I made a simple substitution in my most famous equation. If instead of E = mc2, we accept that the energy to heal the world can be obtained through love multiplied by the speed of light squared, we arrive at the conclusion that love is the most powerful force there is, because it has no limits.

After the failure of humanity in the use and control of the other forces of the universe that have turned against us, it is urgent that we nourish ourselves with another kind of energy…

If we want our species to survive, if we are to find meaning in life, if we want to save the world and every sentient being that inhabits it, love is the one and only answer.

Perhaps we are not yet ready to make a bomb of love, a device powerful enough to entirely destroy the hate, selfishness and greed that devastate the planet.

However, each individual carries within them a small but powerful generator of love whose energy is waiting to be released.

When we learn to give and receive this universal energy, dear Lieserl, we will have affirmed that love conquers all, is able to transcend everything and anything, because love is the quintessence of life.

I deeply regret not having been able to express what is in my heart, which has quietly beaten for you all my life. Maybe it’s too late to apologize, but as time is relative, I need to tell you that I love you and thanks to you I have reached the ultimate answer! “.

Your father,

Albert Einstein

100 Years Later, Scientists Conclude: Einstein Was Right!

Have you ever felt as if you were ahead of your time? Einstein was, and recently scientists were able to prove a key part of his theory of relativity.

IF A TREE FALLS IN A FOREST AND NO ONE IS AROUND TO HEAR IT, DOES IT MAKE A SOUND?

That is a question pondered by many and often used as a thought experiment.

Regardless of whether you look at that question from a philosophical or a scientific standpoint, it seems to be a matter of opinion that is still up for debate.

If we were to rephrase that question to make it match portions of Albert Einsteins general theory of relativity, it might then be stated as “If two black holes collide in a binary system with solar masses, can we detect the resulting gravitational waves from space on earth?”

Except that question is no longer up for debate. It has a definitive answer.

YES.

For the first time we were able to detect the echoes of an event that took place more than 1.3 billion years ago.

Recently scientists at two separate Laser Interferometer Gravitationalwave Observatorys (LIGOs)were not only able to detect these gravitational waves, which are essentially ripples in the very fabric of spacetime, but they were able to pinpoint the source of their impact as somewhere in the Southern Hemisphere as well.

Black holes orbiting each other gradually lose energy while emitting these waves. As they lose this energy they are slowly and methodically drawn closer together over the course of billions of years. As the black holes continue to approach one another their speed builds as well and eventually reaches nearly half of the speed of light just before they collide and the two combine together to become one massive black hole.

When the mass of these black holes is thrown together, it converts a portion of that mass into energy which is emitted throughout the universe in a burst of gravitational waves which themselves cause tiny disturbances that effect both space and time as they pass through earth.

THE IMPLICATIONS OF FINALLY BEING ABLE TO DETECT THESE WAVES IS ASTOUNDING.

Einstein predicted these events one hundred years ago in his theory of general relativity. Even though Einstein didn’t believe in black holes and thought that gravitational waves were too weak to detect, the idea alone that the man was so far ahead of his time that it took technology one hundred years to catch up and confirm his theory is amazing. Even more amazing is the knowledge we will gain from this and how it opens up untold possibilities for understanding the origins and workings of gravity itself.

It’s uncharted territory really. Scientists will now be able to look at the universe from entirely different angles and explore the phenomenon of warped spacetime.

The best part is that it will herald countless new scientific breakthroughs in both physics and astrophysics, which ironically means I can’t stress the gravity of this event enough.
