Daniel Whiteson has one of the most relaxing voices I've ever heard... really a pleasure to listen to. Most of them have boring or even annoying voices. The 'OMG-particle' story is nice material for a positive sci-fi book/movie I'd name 'The Particle Package'.
Dr. Whiteson has such a soothing voice. Listening to the two of you talk kept me from flying off my lid while doing a very frustrating project at work.
That guy knows how to explain physics sussinctly and answer questions directly, very helpful and insightful. PS. underlying music during the interview is distracting and ambiguous, creates false prompts (i.e you think the interview is concluding when it is not). Music beginning and end is sufficient imo. 😃
I'm really glad you took my recommendation of introducing your guest, and stating their credentials before the advertisement. IMO it will help people like me stick around, to hear what your amazing experts have to say.
Absolutely captivating this week. Topics regarding the makeup of the universe I find the most interesting, for some reason. Maybe it's this incessant need I always feel to know how things work and also why things work the way they do. What an episode! Dr. Whiteson has such an open and curious mind, I hope you have him on again!
I echo your sentiment. Whenever I hear dark this or dark that I'm always reminded of the world aether. It was an understanding that something was going on but in hindsight the idea was so far off the mark to be comical, or painful, lol. So flashforward and here we have dark energy and matter. We know something is going on but have zero practical experiments to probe what they might be. Just food for thought. Even religious dogma's believe something else is going on. Could the realms of this unknown substance harbor an explanation for supposed "hauntings?" There is so much we know nothing about, and so much we need to explain. Yet we have stories handed down since time immortal, and people like me whom has lived in a "haunted house," and have been told stories from people who had no knowledge of my own experiences.
@@Benson_aka_devils_advocate_88 It makes for a strong case of there's simply not enough information. I am quite convinced that our perception, as well as our technological means of detection, are too limited to really pick up on the full picture. Paranormal stuff has always interested me. It's something that probably has a logical and reasonable explanation for it all, we just can't perceive it properly to make any assertions about it. I was in what's known as a "haunted tunnel" some years back, and I can attest that something is going on, but without the information of what it was, all it did was scare the bajeesus out of me. This reality in which we inhabit is filled to the brim with mysteries, from in our own back yard of our lovely little blue marble to the far-flung reaches of interstellar and intergalactic space.
There's so much going on that we have no clue about, that's a fact most humans find hard to accept. We are taught how superior we are, and yet there are still mysteries regarding the human body. Funny thing about the paranormal, when you experience it enough it begins to become normal. I fully understand how people can be skeptical if they've never had an experience of their own. Things aren't supposed to move on their own and shadows aren't supposed to have substance and move about the room. And, then, well, you see it for yourself... However, it was when my Mom brought on a roommate, who ended up in my old bedroom, and the woman starts describing the things I'd been seeing that it hit me. It's one thing to think it's your imagination. It's another when a person describes in detail something you've never discussed with anyone, _that's when your understanding of reality shifts a bit._
@@illustriouschin Oh, yeah! I definitely agree your idea, here, is more feasible. Mentioning Three Body/sophons just felt relevant to “insane ideas” involving alien particle physics/quantum entanglement.
Loved this episode, though the soft and comfortable voice of the Guest almost made me sleep. I absolutely love these scientists that are willing to speculate without making the mandatory "serious science" disclaimers in every other sentence :-D. Exploration it is indeed.
I think Daniel got it wrong when talking about alien particle colliders, saying that it is "just" fun speculation. I would say it is FUN speculation. Isn't that why half of us are here? Great guest and great interviewing as usual. Edit: If he gets his cellphone detector app up and going, I for one would love to participate. A link would be nice.
Rewatching this when i should be sleep amazing guest 🎉 I was conviced that that dark mater was just an error in calculation and he described many topics iv researched in great lenghts and had a fresh take on loys of stuff 🎉
Before we explore the strength of interdimensional gravity, best we remember the exponential fall off of magnetism's strength over distance. The guest cites a fridge magent overcoming the gravity of the earth, you ain't see ing that magent at the moon, let alone at any of our lagrange points, but you'll still be gravitationally bound to earth (and the sun) at those locations.
What I find comforting is the realization that a high energy accelerator is unlikely to cause the cosmos to unravel as we are are not anywhere near the energies of the high energy particles already flying through space.
Relistened for the umpteenth time, finally heard that he developed the app my og post was asking about. Now im asking where can i download it? The only website i found was a sorta shady looking one, so i wanna be certain before downloading anything

Mr. Whiteson was amazing. This was an awesome interview/discussion. I really liked what he said about time travel and why he believes it can't really happen. 👍
I just heard you on Jimmy Church, that was an equally interesting conversion. I am so grateful for people like yourself, Isaac Arthur, Avi Loeb, Brian keating and many other scientists ( especially Astrobioligists), who are applying they're education too topics, the likes of which were never addressed or outright shunned during my youth ( and yours as well, I am 45 years old). I have always had an interest in science, and we both grew up in what I would consider a dogmatic time in science and mathematics. It is only in the last decade, I am finding accredited scientists willing to address in a serious manner, quite frankly the most interesting questions out there, and some of the bizzare outcomes of Quantum Mechanics. Many factors have lead us to this point, but podcasts such as yours have helped grease the wheel. Speculating about where science or math could take us, is one of coolest things humans can do; thanks.
Had to lol at what might be the best description of GR that I've ever heard: ...vibrations of a trampoline, and all that "tensor stuff..." You're not wrong...lol
Moving clocks run slowly. If someone is in a rocket ship traveling at high speed relative to Earth, everyone on Earth would see the rocket's clock running slowly. But velocity is relative, so the rocket ship's pilot sees the Earth as having high velocity, and the Earth's clocks as running slowly. It seems bonkers, but it's true.
For some, the point of confusion is consistency: how can both clocks seem to be running slowly? The answer -- and this is the core issue in relativity -- is about the meaning of 'simultaneity'. To compare two clocks, you read them *at the same time*. But the two observers don't agree what "at the same time" means because simultaneity is not universal in relativity, it depends on location and speed.
Have to agree with all the other comments. Def one of the best episode's. Great guest. Great info. Great voice too. Please have this guest on again Plus i have a question. Could matter outside the observable universe have a combined gravitational force large enough to create some of the gravitational effects that might explain things such as the expansion of the observable universe, and maybe even dark matter/energy. And if it could be the case, can you then calculate (from the expansion rate) how big the entire universe is (not just our observable universe) in terms of the amount of matter (Apologies if I'm making no sense. I excel at it)
Essentially no. The problem with the expansion of the universe is that it's defeating gravity, everything is moving away from everything else in general. We can only assume this is also the case for the unobservable universe. So you need something to drive that and the best fit is the expansion of space-time, but that appears to be accelerating. That's where dark energy is invoked because you need something to drive that in turn. Now dark matter on the other hand is a matter of gravity, we can see it's gravitational effects on very large scales, but that's it. How that plays into this equation is mostly unknown without knowing its nature. So we don't really have a way to determine exactly how large the universe is, but we have a hint. Mounting evidence is showing that the geometry of the universe is flat. There are open physics questions there that need to be addressed, but it hints that the universe may actually be infinite.
@@JohnMichaelGodier Doesn't *Gödel's Essential Incompleteness Theorem* state that any axiomatic system that tries to talk about infinite sets must necessarily be incomplete?!? ... and what would it mean to have a logically self-constrained system of physical law that had to be incomplete?!! I'm with Max Tegmark here; Physics needs to find ways to banish infinity from it's doors as anything other than a useful and necessary epistemological and mathematical device.
Here's a chicken and egg problem that's fun to think about; which happened first,.. consciousness or sensation!?!? ... and how did either do so in a manner consistent with Physical Law as presently understood. If present understanding is inadequate,.. what more would we need to learn,.. and where from?
I think my autism is showing. I covet completion,.. but my Daoist soul is deeply suspicious of overly pat answers. Just as a snowflake requires a bit of particulate matter in order to start forming, or the necessary use of axioms in anarchistic mathematics,.. I wonder how much choice God had in creating the Universe; It would seem less and less all the time.
@@JohnMichaelGodier Could ways be found to extract useful work out of dark energy/matter? How do the laws of thermodynamics apply to dark energy? Is the overall universe thermodynamically open or closed and does the presence of dark energy change the resulting answer to this question? I tend to be enough of a sci-fi buff to think that intelligence may yet be responsible for determining the final fate of the Cosmos,.. more so than merely raw nature alone. If Humanity ever found ways to make dark stuff useful,.. it would likely either destroy us or make us,.. or maybe even both at the same time.
Is gravity a force ? IMO its not, there's are no opposite but identical properties like other forces, no positive charge for the negative charge, no South pole for the North pole, etc. I think Einstein has it right its simply an "effect" on the space time plane due to mass. So maybe the "effects" i.e. "extra gravity" in what's termed "dark matter" is simply a gravitation gradient from matter in other "stratum(s)/layer(s)" of Space time planes that bleed through to our Space time plane ?
I think that lower layer idea also works for explaining red shift and the uniformity of the cosmic background. Consider the metaphor that the substrate of our scale of the universe is thickening.. It explains more than expansion IMO.
I am no cosmologist, or an astrophysicist oh, so maybe this is more my misunderstanding of things, but... I thought the accepted theory was nothing could go the speed of light because it would take all the energy and the universe to do so. This particle was as close as you can possibly get, arguably the speed of light, and obviously it did not use all the energy in the universe. In fact on universal scales, it used so relatively little that no absence of energy anywhere was detected
and you think the universe came into existence with a bang explosion out of nowhere and randomly created all the starts ans planers including Earth and its complex and beautiful life forms ?? Haha
@@waterproof4403 Yes. But its not random, its physical laws of nature. What you fail to consider our understand us the vastness of the Universe and the amount of time that has passed. But if you want a real laugh, consider it all was created by a deity that created itself from nothing and then proceeded to create everything, also from nothing, in 6 days. And this deity exists beyond any laws of nature. It gets funnier, but that's enough for now.
What an amazing and captivating episode! It left me with much to wonder about our understanding (or in this case lack thereof) of mass in this amazing universe in which we liiiiiiiive.
Super fascinating episode! It's funny to me, though: I realized that Stargate:SG1 has kinda ruined me. I can't hear anyone talking about neutrinos without hearing Jack call them "nintendos". And then you guys start talking about actually creating wormholes, and I'm just... "You need two big rings, to start with."
However complex a program you are using on your pc is, its all at its core its just ones and zeros right? So would the different vibrations of the strings in string theory basically be our ones and zeros? (if you view it in a very simple matter ofcourse)
Some of us seem to have gotten a little too cocky. Lets slow down a minute. The human race is a little young in this astrophysics thing. Just because we have made discoveries doesnt mean we now 100% of everything. We might actually go out there eventually and find out we were off by a little bit or totally wrong. It seems to me that when I watch an Astrophysics documentary some of our scientist make it seem like "Hey we know everything and we are the smartest ever and have this all figured out." I am not saying thats what they are but what the normal person thinks it sounds like.
Great topic! This is something that almost every human who has ever lived has probably considered at some point in their lives. Regardless of their station in life or level of education. If you could ever make it happen I would be really interested to see this topic revisited with someone that likely has a much different perspective than your typical scientist like the Director of the Vatican's Observatory Brother Guy Consolmagno. Edit: Really enjoyed the guest too. I have the most respect for a scientist who is open minded enough to not be dogmatic and declare openness to ideas that aren't "mainstream." In my mind, dogma is an anathema to true scientific discovery.
Brother Guy at the Vatican is forbidden from inquiring into the moment of creation. This directive was also discussed when the Pope had a meeting with Stephen Hawking. You can study the big bang or the expansion if the Universe but it is forbidden to study, or inquire into the Universe at t=0. Of course Religion is not a science and has no jurisdiction or legal authority to restrict the nature of Research in the field if physics. (Technically, current Understanding in Physics limits understanding or study of the Universe and the big bang at times greater than the Planck Time (~10^-44 seconds). The smallest time interval measured so far us orders of magnitude larger than the Planck time - roughly 10^-21 seconds. We have a long way to go to reach even the theoretical time limit let alone understand what happened at t=0)
We assume G is constant. We assume space time is constant. We assume the physic in our universe is constant. Maybe over time and space , physic isn’t constant. Maybe physics changes with the age of the universe.
@@freehat2722 cheers. Clearly an evolution of physics at the early stage of the universe. Maybe physics changes with entropy. Although I hear many dismiss this idea.
56:40 "The present uniquely determines what the past was." - "The whole history of the universe is encoded in the present moment of the universe." 59:00 Each set of current present "primitives" exist relative to a future set of present "primitives." - What about this idea? - The present is stationary at the beginning of time. The future is a steering mechanism somehow designed to manipulate the past to create a more advanced present moving on a W axis.

If Humanity ever found ways to make dark stuff useful,.. it would likely either destroy us or make us,.. or maybe even both at the same time.
Awesome stuff!!!!
If you seek to know the big thing, you also must look to know the smallest of the small.
Great falling asleep upload, just under 10 minutes, I was gone.
Is gravity a force ? IMO its not, there's are no opposite but identical properties like other forces, no positive charge for the negative charge, no South pole for the North pole, etc. I think Einstein has it right its simply an "effect" on the space time plane due to mass. So maybe the "effects" i.e. "extra gravity" in what's termed "dark matter" is simply a gravitation gradient from matter in other "stratum(s)/layer(s)" of Space time planes that bleed through to our Space time plane ?
I think that lower layer idea also works for explaining red shift and the uniformity of the cosmic background. Consider the metaphor that the substrate of our scale of the universe is thickening.. It explains more than expansion IMO.
Great conversation. Is Daniel making love to the microphone?
Just finished listening and WOW
I am no cosmologist, or an astrophysicist oh, so maybe this is more my misunderstanding of things, but... I thought the accepted theory was nothing could go the speed of light because it would take all the energy and the universe to do so. This particle was as close as you can possibly get, arguably the speed of light, and obviously it did not use all the energy in the universe. In fact on universal scales, it used so relatively little that no absence of energy anywhere was detected
and you think the universe came into existence with a bang explosion out of nowhere and randomly created all the starts ans planers including Earth and its complex and beautiful life forms ?? Haha
@@waterproof4403 Yes. But its not random, its physical laws of nature. What you fail to consider our understand us the vastness of the Universe and the amount of time that has passed.
But if you want a real laugh, consider it all was created by a deity that created itself from nothing and then proceeded to create everything, also from nothing, in 6 days. And this deity exists beyond any laws of nature.
It gets funnier, but that's enough for now.
What an amazing and captivating episode! It left me with much to wonder about our understanding (or in this case lack thereof) of mass in this amazing universe in which we liiiiiiiive.
mV seems to rule, alright
EXCELLENT !! if NOT OUTSTANDING! HOST - JOHN MICHAEL GODIER. & GUEST DANIEL WHITESON. FROM, U.K. (2023).
Super fascinating episode! It's funny to me, though: I realized that Stargate:SG1 has kinda ruined me. I can't hear anyone talking about neutrinos without hearing Jack call them "nintendos". And then you guys start talking about actually creating wormholes, and I'm just... "You need two big rings, to start with."
So what im getting from this is in order to create wormholes we just need to create two big rings of Nintendo products. Quick, to Japan!
Great episode!
However complex a program you are using on your pc is, its all at its core its just ones and zeros right? So would the different vibrations of the strings in string theory basically be our ones and zeros? (if you view it in a very simple matter ofcourse)
The organs in the background are a nice touch lol
Epic episode
Excellent work - also everybody it helps him if you like and share his content.
I like this fella. Very interesting as per usual.
Great video and information !
When I first heard this show, I thought John Diliberto from "Echoes" was narrating. Even though you're not John, I love the show.;-)
Best show I've heard maybe ever. And what is the incredible music at the end of the show?
"Ascent" by Stellardrone
He took the words right out of my mouth ...... uncanny
Out of curiosity, have JMG and NdGT ever being in the same discussion? I'd love an episode of that
No. Not yet.
Okay. I'm a big fan of both podcasts. Much love from Kenya 🙂
Why do we need a beginning anyway?
JMG totally good with and enthusiastic about creating mini black holes 😂 “send it”
Your guest was superb and had such a soft, soothing voice. It was a pleasure to listen to him.
Some of us seem to have gotten a little too cocky. Lets slow down a minute. The human race is a little young in this astrophysics thing. Just because we have made discoveries doesnt mean we now 100% of everything. We might actually go out there eventually and find out we were off by a little bit or totally wrong. It seems to me that when I watch an Astrophysics documentary some of our scientist make it seem like "Hey we know everything and we are the smartest ever and have this all figured out." I am not saying thats what they are but what the normal person thinks it sounds like.
What's the name of the APP??

Great topic! This is something that almost every human who has ever lived has probably considered at some point in their lives. Regardless of their station in life or level of education.
If you could ever make it happen I would be really interested to see this topic revisited with someone that likely has a much different perspective than your typical scientist like the Director of the Vatican's Observatory Brother Guy Consolmagno.
Edit: Really enjoyed the guest too. I have the most respect for a scientist who is open minded enough to not be dogmatic and declare openness to ideas that aren't "mainstream." In my mind, dogma is an anathema to true scientific discovery.
You know Brother Guy has been on the show?

@@EventHorizonShow Thank you! I remember that episode now. In my head it was another podcast he was on.
Such a great guest, this episode was especially captivating.
Brother Guy at the Vatican is forbidden from inquiring into the moment of creation.
This directive was also discussed when the Pope had a meeting with Stephen Hawking.
You can study the big bang or the expansion if the Universe but it is forbidden to study, or inquire into the Universe at t=0.
Of course Religion is not a science and has no jurisdiction or legal authority to restrict the nature of Research in the field if physics.
(Technically, current Understanding in Physics limits understanding or study of the Universe and the big bang at times greater than the Planck Time (~10^-44 seconds). The smallest time interval measured so far us orders of magnitude larger than the Planck time - roughly 10^-21 seconds. We have a long way to go to reach even the theoretical time limit let alone understand what happened at t=0)
I really enjoyed this one
Great content as always.
We assume G is constant. We assume space time is constant. We assume the physic in our universe is constant. Maybe over time and space , physic isn’t constant.
Maybe physics changes with the age of the universe.
..or the laws are fixed but there's still a wide variation in how they express under various conditions at our scale of understanding..
@@freehat2722 cheers. Clearly an evolution of physics at the early stage of the universe. Maybe physics changes with entropy.
Although I hear many dismiss this idea.
I've been watching your show for over a year now. Always look forward to a new one . Your interested in the same stuff I am
Thank you for watching. What are your favorite subjects? Oh
Do you have any 2XL black shirts available to purchase?
Hi Ben, here’s one. event-horizon.creator-spring.com/listing/event-horizon-merch?product=211
Exploding stars, the degree of randomness in complexity of matter.
56:40 "The present uniquely determines what the past was." - "The whole history of the universe is encoded in the present moment of the universe."
59:00 Each set of current present "primitives" exist relative to a future set of present "primitives."
- What about this idea? - The present is stationary at the beginning of time. The future is a steering mechanism somehow designed to manipulate the past to create a more advanced present moving on a W axis.
Good one
ASMR for nerds. Thank you!
