Stephen Hawking Last Speech – Boundary Condition

Hi guys, How are you all? Today we are going to read about “Stephen Hawking Last Speech – Boundary Condition“. So be ready for this extremely informative journey, so let’s start.

    Stephen Hawking Last Speech

    Can you hear me, I am delighted an honor to receive a special prize in fundamental physics. I would like to thank Yuri Milner for founding these prices to recognize outstanding work that may not qualify for the Nobel Prize because it is very difficult or impossible to confirm experimentally. 

    In my case, although almost every theoretical physicist agrees with my prediction that a black hole should blow like a hot body that would be very difficult to verify experimentally. The temperature of the macroscopic black hole is so low. 

    I thought my discovery would never be confirmed or recognized. However, it could be blamed that it has already been indirectly confirmed by observations of the microwave background. That is thought that the very early universe underwent a period of accelerating your inflationary expansion, this would create conditions similar to a black hole and would give the universe an effective temperature. 

    Thermal fluctuations in the very early universe would be frozen and with all small differences in the microwave background in different directions, this have been observed and agree with reductions. 

    The thermal emission from black holes is important because it shows that black holes have intrinsic entropy when it shows that there is a deep connection between gravity and thermodynamics. That plays a key role than the ADRC FT Doherty. I have also made contributions to cosmology 

    My early work with Roger Penrose showed that classical general relativity predicted the universe had a beginning in the Big Bang singularity. That the universe had a beginning in the Big Bang 13.7 billion years ago is now accepted by most people working in cosmology and is supported by the discovery of a failed background of microwaves. 

    The prediction of singularities indicates that classical general relativity breaks down and has to be replaced by a quantum theory of gravity. Them heard when I proposed that the quantum state of the universe should be defined by a path integral over all compact Euclidean matrix without boundary. 

    In other words, the boundary condition of the universe is that it has no boundary. The no boundary condition implies that the laws of physics hold everywhere even at the beginning of the universe. Together with Thomas Hertog Lymon, I showed that a no-boundary proposal predicts that the universe began with a period of inflation a prediction which made me confirm tomorrow when the data from the Planck satellite are published. 

    I feel a sense of achievement that I have managed to make these contributions despite having ALS. I have not allowed my disability to stop me doing most things. My motto is there are no boundaries thank you.

    The Preciousness of Time: A Stephen Hawking Tribute

    I am very aware of the preciousness of time.

    I was given two to three years to live. 

    I faced a life unable to properly communicate Fortunately, my mind was unaffected. 

    While all around me people had passed away, deep in conversation I have often been transferred into her.

    Lost inside my own thoughts Trying to fathom how the universe works.

    Perhaps it is human nature that we adapt and survive. 

    We have this one life to appreciate the grand design of the universe. 

    There is still plenty more to find out.

    We are all time travelers, journeying together into the future.

    Let us work together to make that future a place we want to visit. 

    I am convinced that humans need to leave earth and make a new home on another planet. 

    In the next 100 years, we will embark on our greatest ever adventure. 

    Our destiny is in the stars, So remember to look up at the stars and not down at your feet. 

    Try to make sense of what you see and wonder about what makes the universe exist. 

    Be Curious.

    So these are enough for today. Comment what is your opinion about this post “Stephen Hawking Last Speech – Boundary Condition“.

    Thanks for reading.
