For many, time is long during this coronavirus epidemic and often synonymous with boredom. It can, however, allow us to learn about ourselves.
PHILOSOPHY – Time goes by and the days look the same. It sometimes becomes difficult to distinguish a Tuesday from a Saturday, or even to know exactly what day of the week it is. For French people who do not work or telework, time may have become strange since the beginning of the containment against the coronavirus pandemic.
For some, it can stretch, for others, it can pass faster. Either way, it seems to have become distorted. “The time pattern has changed completely, it’s transformed, even for people who are teleworking or who have to do everything at once. When the relationship to space changes, the relationship to time changes,” says philosopher and psychoanalyst Hélène L’Heuillet, author of “Éloge du retard: Où le temps est-il passé”, contacted by Le HuffPost.

Could Einstein and Hawking together have reconciled relativity and quantum mechanics? This captivating documentary mirrors the discoveries of the two greatest minds in modern physics who revolutionized our vision of the Universe. This first part looks at the work of Albert Einstein (1879-1955). Relativity, the Universe seen as a space-time continuum and attraction as a distortion of this continuum caused by stars and planets… This first part looks at the work of Albert Einstein (1879-1955). They are put into perspective by astrophysicists, in particular those of the Laser Interferometry Gravitational Wave Observatory (LIGO), which brings together 900 scientists from around the world. How do researchers today view the ideas of the Swiss-American genius?
It was Albert Einstein who first shattered Isaac Newton’s hypothesis of a universal time and explained that it is in fact a subjective experience. An episode in a captivating documentary series on the mysteries of the cosmos. If man has been trying to measure time with increasing precision for thousands of years, it would be difficult to define it, as it is still one of the greatest mysteries of physics. For the perception of its continuous flow is nothing but an illusion. Albert Einstein was the first to shatter Isaac Newton’s hypothesis of a universal time and explain that it is in fact a subjective experience. Why is this? Simply because movement in space affects its flow. Einstein thus reveals the fundamental connection between space and time, inducing in passing that past, present and future exist in the same way and without distinction!

Space separates two galaxies as well as two atoms. Author of the book “The Magic of the Cosmos”, published in 2004, the physicist Brian Greene reveals that it is a dynamic fabric that can stretch, twist, deform and undulate under the effects of gravity. Even stranger still is the recent discovery of a mysterious ingredient that is said to make up 70% of the universe and which physicists call “dark energy”. Even if they admit its existence, they still don’t know what it is. Examining space on infinitely small scales only makes the mystery even deeper. 3D animated sequences prove that our ability to reason quickly reaches its limits and struggles to influence our behaviour. Mundane objects such as matches and chairs allow for surprising experiments when handled by researchers. To prove the validity of their theses, researchers don’t hesitate to jump on a surfboard or study the methods of magicians. All of these are reasons to worry sometimes, especially when we learn that our brains make decisions seven seconds before we are aware of them! A fascinating journey to the four corners of the world, from Australia to Germany via the United States and Sweden, to observe our neurons in all their states..

RTS report at the UniNE Time-Frequency Laboratory. The LTF is starting its 15th major contract with @ESA, the European Space Agency, for the creation of a new generation of atomic clocks for use in space (for Galileo, the European GPS).
“Time passes and I “pass” in time, it’s a phenomenon that I live, that I feel, that transports me irresistibly. All I know for sure is that he’s older than me, but when did it start?”
The way the fabric of space and time swirls in a cosmic whirlpool around a dead star has confirmed yet another prediction from Einstein’s theory of general relativity, a new study finds.
That prediction is a phenomenon known as frame dragging, or the Lense-Thirring effect. It states that space-time will churn around a massive, rotating body. For example, imagine Earth were submerged in honey. As the planet rotated, the honey around it would swirl — and the same holds true with space-time.
Satellite experiments have detected frame dragging in the gravitational field of rotating Earth, but the effect is extraordinarily small and, therefore, has been challenging to measure. Objects with greater masses and more powerful gravitational fields, such as white dwarfs and neutron stars, offer better chances to see this phenomenon. ….
Rehabilitate the backlog to regain time to live with the current injunctions on performance and profitability. Hélène L’Heuillet, psychoanalyst and lecturer in philosophy at the University of Paris-Sorbonne, talks about it in her “Eloge du retard” (Albin Michel, January 2020).
