RE: Getting grips on the pre-big-bang era with a universe/anti-universe pair
Thanks for this nice message. I am trying to post once or twice a week about novel physics ideas (basically scientific articles connected to state-of-the-art research). As I said in one of the other comments, I am spending most of my steemit time in helping others through the steemstem project (which takes really really a lot of time...), so that I am left over with very little time for my own blog.
Don't hesitate to recommend the audiobook to others (who is the author by the way?), they may like it. I have unfortunately no time to watch movies or listen to audiobooks... but some other may. I personally prefer reading ^^
i can imagine someone who gets asked to go speak at cern doesn't really have much time, but i also imagine you do what you like, which must be quite the fulfilling life.
the book is -- Astrophysics for People in a Hurry - by Neil deGrasse Tyson -- , available in both e, paper or audio from the usual sources which i wont link i suppose anyone interested will be capable of using google. There was a version on youtube too for people who can't afford but i know thats officially not ... then again, if it's in a public library somewhere its debatable but not on your feed by off-topic ofcourse.
I really appreciate you taking the time to answer too. I wonder if you do requests ... if you could ever do a piece on time, i mean time the way a physicist sees it.
I personally feel (im by far not a scientist but im duly interested in the world of physics as well as the more analogue human psyche)
I feel time is not a force as such but , allow me to try and explain and pardon if i use some words in the wrong place, terminology has never been my forté.
Time, as i see it is a variable in mathematic formulation, just like numbers its a human construct devised to explain, but just like numbers it actually doesn't exist in a physical form. Its merely perceived as an observation of change. I mean , there's actualy forces electromagnetism, gravity, the more abstract concept of entropy over time pushing things outward and the fact that all things in existence on all levels seem to vie for a state of balance or equilibrium is actually what makes everything move, collide, what provides friction and energy (which means mass, right ?) but time actually is not a force at all, for all i know time has not even been proven to exist so , my original thing its a construct needed to explain the physical reality through mathematics, but not a physical reality (like the aforementioned forces).
I know this is probably closer to metaphysics but id seriously like your opinion and if you ever do a piece on time, much obliged :)
in short : "If mathematics is a language, then 'time'is but a word." (i'll keep that for my future ted-talk once i graduate form steemstem-academy lol) ... the things that keep bouncing around in my head ...
(i would also ofcourse recommend to anyone the classic by Carl Sagan : cosmos which taught me a lot on the world here as a whole too, explained in 'normal' language and timeless piece of literature i think)
I have heard about the book, but I have never read it. I have actually very little tie to read books. It is a shame :/
I already did it in the past. If this is connected to wha I do or what I know, I can write on a given specific topic. So feel free to suggest anything.
I am not too sure to understand what you meant in considering time as a force. Time is not a force. It is a quantity that allows us to order events. I will try to write a post on time next week, maybe, if you want, and more in particular on how time is defined (in other words, how to rely on clocks).
