'Is my deceased grandmother still alive?' Physics and existential questions. #shorts

I love your curiosity, your humor and not afraid to just be yourself. Thanks 😊

According Penrose all thoughts exist in quantum superposition, so all experiences of all creatures will stay there forever

[chhewee]

umm energy never dissipates it just transforms, is probably what is being meant. 😊

This is a great, human and hopeful book, understandable for everyone, recommend to read.

Rediscovering the immortality of the soul. We've come full circle, eh?

[TheIgnoramus]

Well, if time is just the perceived entropy of space, then technically all events that ever happen exist somewhere, somehow…or not 😂

There is an episode of Trailer Park Boys where Bubbles tries to convince Ricky that his goldfish is still alive for the same reasons. I love it.

The last one was surprisingly optimistic . Love it ❤

[ElCapitanDeLaNoche]

Thank you for the acceptance of the concept. Now, all we have to do is find an experiment to test the idea.

This probably happened to her in Berlin 😂 typical Berlin stuff 😅

I'm so glad she didn't break that young man's spirit.

[DropdudeJohn]

First time I have seen her feet, now I know they are real

[Mia-gexf]

Make a video on how to make a good reputation❤

years before my daughter was born, she was already on the way, already existed but not manifested because energy cannot be created nor destroyed, just changes forms, right?

[Waterdust]

So we don't get to know if she's still alive unless we pay for the book? Eh.. at least I didn't have to suffer 4+ ads just to hear her talk this time. Is this book available digitally or just hard copy (not my ideal option).. i'm considering it.

Yes, afterlife exists. My father died on the operating table during heart surgery. He was under very heavy anesthesia. If anyone has had surgery you count down and then wake up, there is no in between. When he was recovering in ICU he told me about being somewhere else. He described it in detail, a place that was beautiful, he felt at peace, colors were vivid, there were buildings and streets, and brief communication with someone, etc.. Sadly he passed away 2 years later, however it has given me so much comfort knowing he is at the place he described.

I don't know what to think of her
She thinks she is so smart. Alone the tone... She is doing a great job about spreading physics enthusiasm, but she surely it's one of the highest cited physisics...

[marashdemnika]

I was thinking about the same things. Who’s knows

[mortenfransrud]

Her mouth movements were in a quantum position.

Sorry, but this question obviously suggests, that there is an answer. But that isn’t the case at all. At least, If I understand Relativity right, the question „Is my grandmother still alive“ in general doesn’t make any sense at all. It makes sense only with respect to a certain world line. And with respect to any such world line, my grandmother really is either alive or dead, but not in some kind of “Superposition”. She is dead with respect to my world line and alive to some other world line. Unfortunately the taxi-driver’s grandma is definitely dead in his “personal universe”. But this does not necessarily imply, that the universe is a block universe. Nevertheless, theoretically it could be one, of course, But - as of today - nobody, who meets my world line in some way, can be sure.
(In Gerneral Relativity two points in spacetime, that aren’t “world-line-coherent” (I.e. that can’t be connected by a world-line) might be theoretically be wirld-line-coherent by a world-line means of a wormhole. Butuntil today, (at least from the viewpoints of the Taxi-driver and his grandma) nobody ever observed such a wormhole yet. Therefore - for the time being - the question wether such a wormhole is just a theoretical artefact or wether it has some physical reality at all, necessarily - from the scientific point of view - remains open. I personally hope, this uncertainty comforts the taxi-driver in some way.)
(PS: In the Topology of the Minkowski Space, world-line-coherence isn’t transitive in general.)
