"We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology." - Carl Sagan
Do Stephen a solid and read A Brief History of Time. And never forget the importance of knowledge. The Demon Haunted World by Carl Sagan is another great one.
RIP Stephen Hawking, one of the truest niggas who ever walked the face of the earth.
I remember reading A Brief History of Time while in middle school. I picked it up out of the public library on a whim. I was surprised at how easy of a read it was for a topic that is so complex. It was at that point I understood that the most complex topics in human history were easy to understand at a high level if explained simply, that the knowledge was easily accessible to someone like me.
It's one of the few books that I can point to that I can say legitimately changed my life.
It is a small case filled with fiddly little bits which work in concert to differentiate between right now, while ago, and in a little bit.

And gravity will be exponentially increasing with every millimeter of your body as your approach. You'd definitely notice the stretching and pulling of your body as your approach the event horizon. Black Holes and Time Warps did a great job at describing this for me to understand.
a great book on GR i like is called "Why does E=MC^2" written by Dr. Brian Cox and Jeff Forshaw. they tell you when you can skip a head if you don't want to go through all the math, and they really break it down. almost like ELI16
“Flatland” is a very thin book and worth the read. Don’t even need to check it out of a library, you can finish it in a few hours.

Stephen Hawking - A Brief History of Time
A landmark volume in science writing by one of the great minds of our time, Stephen Hawking’s book explores such profound questions as: How did the universe begin—and what made its start possible? Does time always flow forward? Is the universe unending—or are there boundaries? Are there other dimensions in space? What will happen when it all ends?
You might be interested in reading this book, which will explain in an understandable fashion under what conditions time travel to the past is possible:
Black Holes & Time Warps: Einstein's Outrageous Legacy
by Kip Thorne
More elegant but not necessarily better
There's no real way to ELI2 Quantum Physics without this book, but the closest I can get is that the physics of the super tiniest things is super weird and makes it so that the electrons don't want to hang around that close to a nucleus for any sustained amount of time, just the just zip around close by
There's a cool little book called "Flatland - A Romance of Many Dimensions" which describes a group of creatures living in a 2D just as you describe.

> I also know a bit of spirituality or what i call it unexplained physics
Be wary of the supernatural -- that stuff is fake. If a claim does not have adequate evidence to support its hypothesis and cannot be peer-reviewed by the scientific community through an academic study or paper, then you should stay away. You should only listen to people who are qualified with a legitimate background in math and physics. This field is filled with so much conspiratorial or fringe bullshit that you need to be really careful about what type of things you are reading or watching.
That being said, a very great starting book for anyone truly interested in cosmology or astrophysics would be Stephen Hawking's <em>A Brief History of Time</em>.
YouTube channels like PBS Spacetime are great, but it's very important that you read books as well. This subject matter can be very complicated and dense and you need to be capable of reading and digesting long-form writing. Books are also really get references that you can highlight, annotate, or refer back to at any time. I personally did not enjoy reading until I was about your age. I picked up some books about space and it changed my life.
I just got back from reading Quantum Physics for Babies and am sad to report to everyone that /u/AngeloCaruso91 may have been bullshitting us.
This is the cover one the one I have so I think it's safe to assume this is the right one
Okay thats fair.; Exact category is often debated.
The less debated fields don't have a replication crisis per se: They have a falsifiability crisis.

It would help immensely to figure out whether physics is computable, i.e. non-circularly causal. Current understanding has it that any closed timelike path ("time machine") through spacetime will cause all manner of mayhem. Like, "Newtonian physics doesn't work" kinds of mayhem. Not just silliness like breaking the conservation of energy or momentum -- but really insane things, like being unable to predict the direction of a thrown baseball. For an exploration, read Black Holes and Time Warps: Einstein's outrageous Legacy, by famous physicist Kip Thorne.
This book is a good start: https://www.amazon.com/Order-Time-Carlo-Rovelli/dp/073521610X
Time is an illusion. It is related to information loss, to entropy, and how our brains perceive that. On the microscopic level, there is no "time's arrow," time does not exist. Cosmologically, there is no "now." Time is related to "falling." Things floating in space-time experience no time.
What we perceive as our universe is just a very special part of something much bigger but inaccessible. Or so I suspect. Almost pseudo-religious but everything points that direction.
Hackeran, just so you know, I have never seen someone completely make up something that's as easily disproven as what you just said. You should be proud of yourself for that.
Chris Ferrie has a large range of science books that are specifically for reading to babies. They're illustrated with fun colors and simple short text.
The idea is that because babies have very impressionable brains, if you read them these books, then they'll develop a more scientific way of thinking earlier in life.
Babies won't know the exact meaning, so it'll stop help them fall asleep just like any "happily ever after" bedtime story.
Three years actually.
Three years between the adoption of standardized time in Zurich (1893) and Einstein's thought experiment for relativity (1896).
If you're interested, I'd recommend "The Order of Time", by Carlo Rovelli

I'll try to summarize:
Prior to trains, each town defined time subjectively, based on the position of the sun.
But with the advent of trains, and to maintain schedules, an absolute time was needed.
They first proposed a single universal time for the whole world (Greenwich mean time, GMT). This didn't go over well for obvious reasons, and eventually lead to time-zones.
In 1893 the clocks in Vienna switched to time-zones (just 3 years before Einstein's famous thought experiment).
Einstein didn't pull Relativity out of thin air.
There was plenty of mounting evidence that time couldn't be absolute (thermodynamics and the speed of light).
This post made my day. The ridiculousness of the, let's call it, "though experiment" defies any sense of logic. The Dunning-Kruger effect has never been so artfully illustrated. OP read some wildly theoretical book written with the due diligence of "9/11 was an inside job"
I specifically linked that book in memory of a camping trip where my buddy read it and was trying to explain exactly this; why time doesn't exist. The problem was, he was violently high and couldn't string any thoughts together. He still made a better argument than the comment you replied to above.
It's been an absolute delight reading OPs tantrums at being challenged on a hill he wants to die on that's really just a landfill

this book is a great read if you have the time and mental interest. it's so good that i've bought the book multiple times due to losing it the first time during a move or something. it's a good one to have on the shelf or coffee table.
No, relativity is totally glossed over. And the designers also assumed that there is one definitive reference point of time. That’s probably because they didn’t understand relativity, but it has the benefit of giving us a simplified universe to play in.
I always assumed there was one single reference for time, like on Earth. What blew my mind was reading “The Order of Time” by Carlos Rovelli a couple years ago, which is how I learned that in reality not only is there not a single reference frame for time, but there CANNOT BE such a thing. I didn’t change my Traveller universe, though. The time reference simplification is no worse than a half dozen others needed to make the game workable.
If you have the inclination, I recommend this book:
Yikes! Does he have any evidence that Einstein was like that or is it like one of those Sittenfeld books that just makes up an alternate life for a real person? (don't love that myself) I really enjoyed this biography of Einstein might be a good palate cleanser: https://www.amazon.com/Einstein-Life-Universe-Walter-Isaacson/dp/0743264746
>Not understanding or comprehending certain subjects or topics doesn't make you dumb.
Absolutely. "No one is born knowing this stuff."

One part of Richard Feynman's genius was being able to communicate with non-experts. These lectures, given to undergrad non-science majors, are phenomenal.
The monkey was right about humans not being perfect.
The only space for opinion is pre-Big Bang, everything else is scientific and mathematical fact, and not even the creation of the universe required a God, and that has been proven mathematically.
I appreciate that you are using religion and philosophy to make the world a better place.
I respect your vision of a world better for your fellow humans.
You would be a good person for that, even without life after death or magical fingers reaching out to change reality.
Also, let me recommend two excellent books on the subject of Time:
These are two very approachable books for non-physicists that deal with time from a physics perspective. I recommend them highly.
They could, that’s an equally valid point of view as well!
But anywhere there is no experiment that can determine whether you are in motion or not.
> Galileo's principle of relativity states "It is impossible by mechanical means to say whether we are moving or staying at rest". If two trains are moving at the same speed in the same direction, then a passenger in either train will not be able to notice that either train is moving. However, if the passenger takes a fixed frame of reference, a fixed point, like the earth, he will then be able to notice the motion of either train. Another thing, if one stands on the earth one will not be able to see that it is moving.

If this stuff interests you I highly recommend this book: https://www.amazon.com/Why-Does-mc2-Should-Care/dp/0306818760/ref=nodl_
It goes through the history of relativity and all the way through how Einstein formulated his theories. It walks you through it and holds your hand very well even if you don’t have much math or physics background.

Na introducao:
> Once we become more familiar with the spirit of GR, it will make perfect sense to think of a ball flying through the air as being more truly “unaccelerated” than one sitting on a table… (which is why we feel a force on our feet as we stand on Earth).
Mais para o final:
> It’s easy to confirm with accelerometers that the ball that appears to be falling is barely accelerating at all, while the table is accelerating upward at 9.8 meters per second per second, known as 1 g. The seeming downward pull of gravity on the ball is an illusion experienced by observers around the table — who don’t believe that they’re being pushed upward either!
