Finished #reading audio #book Brief history of time by #StephenHawking here is my #review
This has been on my to read list since i first heard of it but audio books are limited in my library app
I'm no theoretical physicist but like to think I almost managed to keep up Think my mind blew at least once every three chapters
I had to digest this book before moving onto deeper quantum theory I'll need string theory next
#Multiverse and timelines ahoy
He had a great sense of humour several lols

#TimeTravelTuesday #ThoughtExperiment: Many #Worldlets?

or in other words, fractions of #World, not the whole World. #TimeTraveler #theories often involve splitting or multiplying #universes. Time Travel events divide #spacetime into two near-identical clones. Grandfather lived or did not, you did not meet yourself or you did. But if we think this through further, its scope might not be quite so universal as typically presented.

Take 3 heavenly bodies: Mother #Earth, the #AlphaCentauri triple star system (at 4+ light years away), and #Polaris, the #NorthStar (at 400+ light years away).

Now we program our #TimeMachine to take us back one year (#retrograde) where we meet ourselves. Hi selves! This all takes place in one year. There's the original us, there's us leaving the present, and there's us meeting our past/original selves a year earlier — standard #boilerplate #scifi #movie #script.

Alpha Centauri will have to wait another 3 years before any of this information can get to there. This is related to the concept of a #lightcone which expands at the speed of light. This doesn't sound quite so much like birthing a twin universe, does it? Now what about the North Star? It will have to wait 433 years for news of our Time Travel event(s). And that's still pretty much in our tiny #celestial neighborhood.

The point is that the effects of such events are largely localized and rapidly diluted as we move farther away. This still has its paradoxical problems, but it doesn't quite feel like the whole universe dividing into two — maybe part of it (a universelet? a subuniverse?) Possibilities are that in moving further out in space-time, the effects of a Time Travel incident may be 'blurred out', as are anomalous numerical samples in the law of large #numbers. If one pours a cup of coffee into a lake, it doesn't change the color of the lake. There is a brief chaotic #glitch before it is no longer measurable.

It is tempting to imagine space-time as "stitching" itself back together. (Glitch & stitch?) Such speculations are related to #StephenHawking's "chronology protection conjecture" of 1992. And along with #blackholes, #entanglement, and other #quantum phenomena, if Time Travel is possible, then we should be looking for it at every scale. We could be surrounded by time-traveling particles everywhere all the #Time.

Evidence for #StephenHawking's unproven #blackhole theory may have just been found — at the bottom of the sea
The recent discovery of a stupendously powerful #neutrino has left scientists scratching their heads. New research suggests it could be evidence that Stephen Hawking was right about the nature of #blackholes and the early #universe.

The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

"No one created the universe and no one directs our fate. This leads me to a profound realization. There is probably no heaven and no afterlife either. We have this one life to appreciate the grand design of the universe and for that I am extremely grateful."

The #KrononautMoon Project is an ongoing series of community experiments to contact #TimeTravelers — as "in-person", but more likely via #quantum #signal. The next attempt is coming up soon on 14 Mar 2025 — under the #TotalLunarEclipse — wherever you are. These outreaches are sometimes referred to as "landing receptions", but call them or redesign them however you like. Following is a brief, all-true #chronology of such #events, going back 40+ years. The excerpt is from our detailed #article on Medium.com.

❛❛ #Future #intelligences would have the necessary transport #technology that is not yet existent in our #world. To date, there have been 5 recorded attempts of this method, with the most famous one devised by the late #theoretical #physicist #StephenHawking, in #Cambridge #UK on 2009 Jun 28.

Hawking referred to his get-together as a “reception”—what we now think of as a version type 1.0. His champagne toast to “tourists from the future” was, by no means, not the first of the prototypes, however, because it was staged years after 3 similar experimental attempts — stationed in different #countries and unrelated to each other. The professor’s cheeky soirée occurred four years after a rollicking party that was thrown for “Inhabitants of the Future” at Forrest Place, #Perth #AU, on 2005 Mar 31. Then, a few months later, an equally festive #TimeTraveler #Convention was hosted at #MIT — The #Massachusetts Institute of Technology, #Cambridge #MA #US, on 2005 May 07. These elaborate productions were preceded by a full two decades, back when a group identifying itself as the #Krononauts assembled in #Baltimore #MD #US (alt. spelling: #Chrononauts). That seminal event, which was covered by a #NewYorkTimes reporter, happened at a downtown #bookstore, under the light of a #FullMoon, and a multi-planetary #syzygy, on 1982 Mar 09.

More recently, in the spring of 2023, a dogged #podcaster for TheLastArchive.com and Pushkin.fm, published a riveting and droll #audio recounting of Baltimore’s Krononauts gathering, and then gave the concept a uniquely personal #experimental spin, noting the time and #GPS #coordinates. The effort successfully demonstrated that a single individual can attempt extra-temporal #contact on one’s own, equipped with little more than a #public #library #bench, and can meaningfully contribute to the corpus of #Community #Time #Travel #Research. ❜❜

On 2025 Mar 14, join your #friends, fellow #Mastodonians, and #TimeTravelers for an evening of #peace, #love, and #cosmic #tranquility, wherever you are.

I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.

#StephenHawking's #Chronology #Protection #Conjecture

In this 3-min clip, theoretical physicist Brian Greene explains how physics may prevent Time Travel to the past — known as #retrograde — and says that #Hawking's "protection" conjecture is supported by #mathematics.

Stephen Hawking speaks against creationism

Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going.
