The thing I am most interested in is time travel. I would be real interested in connecting with people on mastodon that have same interests 👌🏾
I tried writing a book last year but lost interest. Need more inspiration 🙏🏿 #TimeTravelAuthors
@Jaden3 Here is another diagram that I find helpful in understanding #TimeTravel re the speed of light in. It depicts #Spacetime intervals. A cone is positioned on 3D axes. The vertical axis is time, two (for simplicity) horizontal axes are space. The narrowest point of the cone is at the origin; the here and now. #WorldLines inside the cone are called time-like. Outside the cone world lines are space-like. Time travel involves going from time-like to space-like world-lines.
«Given the Moon’s weaker gravity (and movement differences between it and Earth), time moves slightly faster there. So an Earth-based clock on the lunar surface would appear to gain an average of 58.7 microseconds per Earth day. As the US and other countries plan Moon missions to research, explore and (eventually) build bases for permanent residence, using a single standard will help them synchronize technology and missions requiring precise timing.»
Coming up with some (presumably) correct + still reasonably short description seems more challenging (to me). My best attempt so far:
<blockquote>
<b>If</b> two astronauts had met "somewhere in (cislunar) space", and subsequently separated from each other,
with one astronaut venturing on to land on the lunar surface, and
the other astronaut returning to the Earth's surface,
such that (as may happen in selected trials)
it takes both astronauts exactly equally long, resp., from separating until reaching (halting on) the Moon, or on Earth,
after some (not further specified) while, either astronaut perhaps being prompted by suitable prearranged signals,
both again take off from Earth, and from the Moon, resp., and they meet again "somewhere in (cislunar) space", where again (trials must be selected such that)
the duration of one astronaut from her take-off until the re-union meeting
happens to be exactly equal to the duration of the other astronaut from his take-off until being together again
<b>then/therefore</b>
the astronaut who had stayed on the lunar surface had remained there
(pretty much) <b>exactly</b>
[\left(1 + \frac{58.7 * 10^{-6}}{86400}\right) \approx (1 + 6.8 * 10^{-6})]
<b>times as long as</b>
the astronaut who had stayed on the the surface of the Earth had remained there.
The Tenth Doctor: People assume that time is a strict progression of cause to effect, but actually, from a nonlinear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly, timey-wimey... stuff.
‘Wobbly spacetime’ may help resolve contradictory physics theories
So, I’m reading some light physics again (Brian Cox & Jeff Forshaw on the origin of Einstein’s E = mc^2), and once again have bumped into the ubiquitous statement in such books that time, unlike space, has an arrow and appears to be unidirectional (which strikes me as little more than a restating of the principle of causality).
I’m interested in any physicist’s perspective on the following thought I have whenever I read this proposition…
⚛ We've had relativity, the physics of time, genius, the speed of light, the Grand Unified Theory, photons, black holes, quantum physics - but this is the first time Melvyn Bragg and his experts have considered Albert Einstein himself.
Did you know that the incredible book, Spacetime Physics, by John Archibald Wheeler and Edwin F. Taylor is available for download under a Creative Commons license?
Read this book, work out the problems, and you'll be on you way to mastering special relativity!
When you say "constraints of the space-time", you mean "known constraints". In fact, you mean "constraints of the space-time as understood by today's science, which incidentally, is fallible, and
has plenty of anomalies in it".
As I understand it, if you can create sustainable conditions in the physical reality tunnel so that your atoms can exist with minimal effort, then your bits are free to travel space-time at will.
Of course, this is not always as easy as it first appears. The human host body must be kept alive if the bits are even going to return to it.
Space-time Travel requires:
acquiring enough credits in the current matrix to provide for basic needs. This is achieved through "work".
enough "mindfulness" to operate the host body, shower it, exercise it, feed it, give it any medicine it needs. This connection between atoms and bits is achieved through meditation.
creating an isolated environment, where you will not be disturbed for an extended period. If your host body has to put "mindful" effort, and dedicate thought to dealing with any disturbances in real-time, the consequences for you, and the space-time continuum could be catastrophic. You suddenly might find yourself in a bizarre, barbaric timeline, full of BS, and remain puzzled as to WTF! Other people in the local reality tunnel might experience you as strange, because you upset their ways of thinking, suited to their own spacetime. Be prepared to be a loner.
it helps to have handy creative tools to record the experience in the consensus reality tunnel, so that you might steer this reality to a better one, that you have seen.
Quantum magic can bend spacetime, according to a new theory. The theory proposes that quantum entanglement, the phenomenon that links two particles across any distance, can also warp the fabric of space and time. The theory could help resolve the paradoxes between quantum mechanics and general relativity, and open new possibilities for quantum technologies. #quantum#spacetime#entanglementhttps://phys.org/news/2023-04-quantum-magic-spacetime.html
Does #time have a direction? This physicist-philosopher says yes -- and that things get very interesting and might explain some conundrums if it's included that way in geometry.
An interesting article on this in Quanta Magazine.
One thing that has become apparent over the last 20 or 30 years is a true change in education - particularly "higher" post-secondary education. While many have pointed out various flaws and problems, they mostly seem to point to differing ideologies ("indoctrination").
That problem is significant. Instilling a particular set of beliefs rather than helping to build the mental skills to investigate and understand the world, and then synthesize a cohesive set of beliefs, leads to failure.
Everything is shades of grey. Everything is relative; a thing can be evaluated differently depending on your frame of reference, exactly as #Einstein described #spacetime.
In the real world, even a coin-flip isn't a 50/50 event. In the Grey Cup a few years ago, the official coin flip landed on edge, and rolled away down towards a storm drain.
If you believe "X is evil" and that it remains so regardless of time, place, experience, or perspective, you can't evaluate it.
Stephen #Hawking showed that black holes aren't stable entities in #spacetime, but gradually decay through the emission of radiation.
The quantum process that powers this Hawking radiation arises based on the difference in the quantum vacuum near and far from the black hole's event horizon.
For the first time, a new study suggests that Hawking radiation doesn't depend on the event horizon at all, and should be present for all masses within #spacetime.
My brother shares my full genome.
He takes a trip and comes back home
Still young, though I am old and gray.
“Well, that makes sense,” I start to say,
“Due to the constant speed of light
Your clock moved slower in my sight.”
“How strange,” he says, “for I saw you,
And from my viewpoint, yours did too.”
