So just going back to the double slit thing. You're saying you basically would need information from both ends to construct the inference pattern, right? So looking at one single end, there is absolutely zero statistical difference (mean, variance, skewness, kurtosis, etc etc) from when detection is happening at the other end? But even there is no statistical difference from pure noise, there is still information embedded in that signal that would be used to construct an interference pattern?
I don't quite get the red and green dots bit and how new older civilisations appeared. Surely older and younger are terms only relevant in comparison to ourselves, and once we emerged the number of older civilisations was set and fixed as a maximum. It can only decrease from there, new older civilisations are impossible. Meaning, that with our continued survival, the number of older civilisations decrease and the number of younger civilisations increase, right up to the point when we are the oldest surviving civilisation.
We developed technology in less than a century and we managed to disrupt our ecosystems in the meantime. Maybe there is an ecological barrier to technological development linked to industrialization. To develop AGI and robots able colonize a galaxy you necessarily destroy the habitability your original planet. Then there is the nuclear weapon variable: a planet dominated by AGI may not be peaceful. There could be different AGI factions, like in our human society. They could just ending destroying each other before the colonization can take place
not sure about to METI or not to METI. However, I think that there is another unspoken challenge, which is how divided nations on earth are right now. For example, Putin or Kim jung-un would probably love to have some aliens go and screw up the USA or western Europe.
In the exoplanet example, couldn’t Bob just not open the box if the planet isn’t habitable? And if it is then cause a change of spin so Alice knows.
Love you videos. Thank you!
Pigs will fly before Starship ever puts something in orbit.
Thanks to you and the team for another thought provoking video. As you already mentioned, Earth's biosignatures and, humanity's technosignatures are already out there. Is it wise to consider the dark forest hypothesis? (en.wikipedia.org/wiki/Dark_forest_hypothesis?wprov=sfla1 if anyone's not familiar with it). Xenopsychology, like assigining values to the elements of the Drake Equation, is just second guessing at best. PS If we do receive a message, what's to stop someone like Elon Musk (other billionaires are available) from replying before the UN can agree on a reply?
How to DECODE the Wow-signal? Did it possibly say something, or was it nonsense?
Oh come on there are countless planets and somehow there is nobody there
I wonder how it can come to a dead stop when it comes out of warp
love the ksp plug
I wonder if advanced aliens don't contact backward ones for the reasons in Stargate SG1 Enigma the Tollans had shared their technology and it caused a wipe out of a both teir planet and the people they shared it with
wow a masterpiece 🎉 also did the dude eventually die askin for a friend 😢
I think I don't mind so much the human race being gone, but the May-June where all life goes is the saddest part
Why would anyone consider putting Earth's population at risk? This is insane. 🇦🇺
What happens if they've seen some of our space travel movies and think they're documented videos?😂
I don't think that the infinite suffering detracts from just making life better on our speck of dust in the universe better for as many as possible as you can only do so much
It should be investigated for sure. It is good to be sceptical but persons like Mick West is sceptical to a radical degree to the point it has become a part of his persona. He has stated things that do not make sense at all, and are just assumptions, which is just as bad like someone who believes anything flying in the sky is a UFO
For me the only way is to consider negative mass in GR like in Bondi extension of GR or like in bimetric gravity. Negative mass does not exist but it can be substituted by negative energy. Negative energy exists. Casimir effect has negative energy, two opposite charges also, two masses interacting gravitationally also. In Italy there is an ongoing experiment aimed at measuring the tiny repulsive gravitational effect of 2 Casimir plates. It is called 'Archimedes' experiment and it's done by INFN and CNR.
Why focus on a pair of entangled particles, one in control room and another in the exoplanet? I think the answer is using 2 pairs of entangled particles. We would send 2 particles to the Bob spaceship and 2 back in the control center, we would have 2 Bobs, and 2 Alices, we'd label them ahead of time so everybody knows which is which, their labels would be: Bob Yes, Bob No, and Alice Yes and Alice No Bob Yes entangled to Alice Yes Bob No entangled to Alice No All of them currently in "undiscovered" state. The question to answer is: Is that exoplanet habitable? If the answer is yes, Bob will "discover" Bob Yes Back in the control center they will need to have a way to compare the states of Alice Yes and Alice No without "discover" both of them, if they see that Alice Yes is 'discovered", and Alice No keeps its "undiscovered" state, the answer is yes, and vice-versa. You can use zeros and ones instead of Yes and No, and billions of pairs to have a digital communication system.
Why should we look for other life when we can't even get on with each other on earth, even if we found intelligent life what would we say to the other life form ? "We want to introduce ourselves to the universe and say hi but we are at war with each other on earth but don't worry we are peaceful "let's find peace on earth before finding other beings
You're telling me you had unlimited intelligence but couldn't program yourself to be feel good about situations that you didnt otherwise? Nature already programs you to do that. Like when you were never attracted to men until you hit puberty. Or women. You couldn't figure out how to stop the universe from going dark? Which isn't that complicated for someone who has the technology to be what you were for so long
Then there is time itself....it stops existing at lightspeed ....will go backwards on FTL......how to make things work with time going back?
No there is no greenhouse effect on earth or venus. At 92 atmospheres it is adiabatic processes that are more than enough I explain the elevated temperature. Pressurized gas is compressed and hot.
So it's better to cook METH- METI... if you're dying to cancer
Can't force yet.
Red, blue, and yellow are primary colors. Green is a secondary color of blue mixed with yellow. 🤦🏻♂️
This video really made me pessimistic about the potential for alien life in our universe. The question can almost be equated to why we don't see other intelligent life on our own planet. We did at one point, but we wiped them out. They don't exist because we didn't allow them to. I suppose I will have to hold out hope that the existence of fossil fuels on our planet gave us a unique advantage in inventing chemical propulsion systems, and maybe there is intelligent life that simply hasn't had the environmental inspiration to gain that knowledge yet.
God created man on the sixth day of creation. He was there, His testimony (the Bible) is true. Over one thousand fulfilled prophecies AND over one hundred major scientific facts recorded in the Bible give us a reason to trust God's word.
The right rare abundance of materials to form planet. The formation of moon, starting in low orbit to have tides starting out 500 ft high to create continal shelves before moon receeds and tides lower . Probably around,600 percise factors involving moon alone. For mineral mix from exploded start to be just right. Certain type star. Earths sun seems most stable star its size found. Amounts of water. Estimated more than three times water in Earth than on surface. Another planet like Earth in entire Galaxy? Each silar system found is as unique as a snowflake... similarities, but so unique when studyied.
The unbelievable video power you and your voice have is…. Just something else. I can’t help but watch your videos for so many reasons. Most of all, science.
The fact that Elon Musk believes we’re living in a simulation is the strongest evidence I’ve seen that we don’t live in a simulation.
It seems possible that one of the key components to creat or to ensure intelligent life will survive and advance, would be to enter a variable to have them always searching for a answer that does not exist , it almost seems imperative to have built in
It seems self-evident that it is not possible to visit the core of our galaxy, due to the excessive radiation found there. In fact, I remember being super impressed with David Braben when he announced that as Elite Dangerous pilots, we would NOT be able to fly to Sag-A, because the radiation would be too extreme for any life to survive, no matter the shielding level. I think I remember him saying that we might be able to approach to within 6,000 Light Years of Sag-A - and that seemed very reasonable to me at the time - 2014 or so, IIRC. Later he very disappointingly reneged on this promise, and we were allowed to fly all the way to Sag-A and back. It was by far the most boring mission I ever undertook. 52,000+ Light Years all up, I think I flew! And so there MUST be a habitable zone in our galaxy - purely because there's a place no life can ever possibly inhabit. And when I say "life", I'm not talking about pond scum hiding under 100km of ice and 200km of water on some iced-over moon close to the core. I mean oxygen-breathing tool-making animals. The question for me is: is there an outer limit to the zone, just as there is an inner limit? Because it is not abundantly obvious that we couldn't evolve on a star at the very end of a spiral arm - or even in the "empty" space between the arms. And here we need to understand that an active galactic core is going to be generating an awful lot more radiation than an inactive one, and that the jets of radiation leaving the galaxy along the axis of rotation would be absolutely deadly for any solar system to encounter. So the size of the habitable zone in any galaxy is going to depend on a multitude of factors. Not least of which will be the age of that galaxy, and hence, how quiet it is. Then there is another question I have: Is it actually possible for meat-sacks to ever colonise anywhere outside of their solar system. And if I'm honest, the answer must necessarily be, "NO!" To me it seems obvious that only virtual humans running in hardware, and occupying android bodies of various types can ever leave our system, and survive. I call them, "Human 2.0".
Seems that we should practice astroengineering on Mars first then.
Like to see a list of the movie clips
Something emotional in my brain thinks the grammar is wrong with the title, but the logical part knows it is not. Fantastic video!!
The solution isn't The Dark Forest Hypothesis? The theory contrived from Liu Cixen's 3 Body Problem trilogy book series?
In the land of gods and monsters, we humans are no angels. Some aliens who venture here may regret meeting us. We are a violent species.
Bro you just don't enough information. Doesn't matter how many formulas you come up with. There's just not enough to go on.
Its comforting to know that I am infinitely insignificant. That fixed my anxiety 😂
On my timeline Vega never gets the warning because I was distracted watching spongebob
Is there intelligent life on Earth? That's debatable.
Isn't it possible that FTL actually breaks the way your diagram represents spacetime, rather than causality itself?
If global warming is so bad, why don't we just cause a nuclear winter to balance it out? Problem solved
Neutronium is a stupid name. It should be called, "Unobtanium." Not because we will never have the ability to obtain the smallest particle, but so that we can some day obtain a sample. Science if filled with examples of nomenclature where things have been given names because we thought they had properties that they did not turn out to actually have. For example, the term "atom" was used to describe the most fundamental particle of matter, something that we later learned it was not. It stands to reason, if we call it unobtanium, we will someday have the ability to obtain it.
I read that it has been recently shown that any signal sent from earth will fade and become indistinguishable from the cosmic background radiation within something like 2 light years. So METI will never work.
I looked away for a minute and almost missed the human race.... Bro that is so sad...
yes it IS a bad idea....it is like going to a casino and gambling your LIFE away....
