Today we explore a problem that has haunted theoretical physicists for decades and remains a topic of active debate - do black holes destroy information? A key precept in quantum theory is that information should be conserved, yet anything that falls into a black hole is seemingly obliterated. How can we reconcile our theories of gravity with that of the quantum world? And could the answer transform the way we look at the Universe...

Why Starship Could Transform Astronomy
I do like the author, really. But have someone a brief description of all this that I can read in 2 mins? I hate setting the speed to 2x...
Physics.
If we exist in a black hole it would explain why we are in such a contained environment and haven't been visited if most life avoids black holes.
Your videos are the abyss's of the universe. The time dilation is astounding...22 minutes feels like 6 minutes due the the effects of special intrests along with general curiosity. The gravitational subject matter mixed with the quantum entanglement of my brain cells is proof my hypothesis should at least be considered a valid prospect, if not proven an actual theory
That star is just a solar hazard material wastedump
Hardly mysterious when we know so little .
I think our problem is we can’t think outside of time. It’s only time that forces the need for a cause.
I still remember as a little boy, about 7, suddenly thinking of who it was who was thinking the question “who is thinking this question?”. I recall the fear, quite unsettling, that it inspired for about 10 seconds, and then the fear passed and the question fell back into an intellectual one only. I tried to re inspire the feeling but couldn’t quite bring it to life as it was the first time, I never have been able to. What a wonderful moment that was.
This girl is so attractive.
What if venus had intelligent life but did the same thing we are doing rn with oil and they did it way too much and this happened

I think aliens are using that star for a trash dump.😅 we're seeing their garbage, alien garbage.
Mr. Worf: "Captain.. Would "I" survive a black hole ??" 11:51
Sounds like the age old problem of how best to polish a turd
I know this is an old video but I still love it❤ Also, I love that you don't say "Novee" or "No-vie" 🤢 it's Nova 🤣❤
I'm not excited about the idea of information conservation. Information has a definition of Entropy that is thermodynamically silly. I just don't see why information can't have a rule like energy. maybe you can't destroy it, but it does disperse so far that it has no information.
Observe the particle which entangles the superposition. They need to be observed from both locations, at the same universal time. Look at this way. Particle one >--< Particle Two “The particles must be observed before they are divided in time and space.” Check the intervals at certain nodes(points in time). Every time the particle is observed it changes the superposition, so create a decibal system. To observe by base 10 (whatever base you like). Basically you have to send data EVERYTIME. The difficult part is knowing what data is VOID! (Null) 10 observations would = Empty
O/T
Oh no Not me I never will desist You're face to face with the Star that can't exist.
For the last five hundred years no human groups are ever completely isolated from each other, so I don't see how we could evolve into separate species. Also a human level of intelligence wasn't possible until the apes evolved about ten million years ago. The brain size of humans cannot be replicated in Reptiles or dinosaurs because they were cold blooded.
Why do they keep saying this, everyone knows they are already here, as does our government. Their is way too much evidence throughout modern and ancient history . Any sort of technology or science learned from this discovery is obviously not just gonna be freely given to the world, unless world governments choose to do so. And any whistle-blowers will always be tinfoil hat men, they make sure of that obviously. Just common sense. Those with power who are on the top of society. Would like to stay there, instead of everyone being empowerd by technology. It's used rather to control and sustain the world order and make sure the elites stay a select few. Again control
If the eternalist view of the time is true, everything is eternal, the past will exist forever in the fabric of the space -time.
I think that it would be better to put almost everyone to sleep and let only some groups "wake up" at a time than just merge everyone.
yerfullakrap!!!
What a nice Moon rock :)
Aliens Might Exist.
pass the damn pepper
I cant tell if im a genius or not, I just realized the green flash effect is another proof that flat earthers are wrong.
Listen, space has this one cool trick, it’s Space! The distsnces between objects is vast. Mind boggling distances. Normally when astrologists or anyone who scans the skies, they pretty much find that there isn’t anything like earth. How earth formed and its characteristics is best viewed as a series of very lucky events, most be consecutive events. We seem to be an anomaly, but again space is vast. It’s best to view it like this, we are alone in the universe, until we are not. To counter the argument that the govt has alien tech….do you think that aliens would even allow that? If aliens can hide their civilization so well, and have the ability to ignore spaces Vastness….im pretty sure they could recover any lost tech. Humans just learned to fly (sustained power flight), 1903. I’m gonna guess, if aliens visited earth, they weren’t 121 yesrs of flight! Another thing, humans grow up believing the world is filled with magic…Santa clsss, illusions, ghosts, movie magic….so when the answer isn’t magic, they sort of reject the answer. Because the answer given, isn’t as exciting. We want to believe we can do more than just live life in a world without magic.
Question: If FTL violates causality and can have universe-destrying consequences, why hasn't Cherenkov radiation done so already?
Because nothing in Cherenkov radiation is going faster than the speed of light. The charged quanta are merely going faster than the group velocity in the Cherenkov medium, which is always slower than c.
So wait, if superliminal speeds are required to reach superliminal speeds could you enter the event horizon of a rotating blackhole and then slingshot out of it by going around the singularity?
No
For a genius you are really had drawing straight lines.
Closed loop paradoxes fundamentally dont exist because of the fundamental changes to the quantum structure of the universe by an observer. You could "go back" in time but it wouldn't be a closed loop, rather a seperat branching curve. Time itself as we understand it is entirely inaccurate as well. Spacetime is not a rigid fabric, but rather a concentrated fluid. The greater the mass the greater the concentration of spacetime. It is these differences in concentration that that create the precieved mass of dark matter in the universe (something that doesn't exist) when in actuality the effects we attribute to dark matter are rather a symptom of relitively different spacetime concentrations. The weak energy condition also does not fundamentally exist. We precieve time in a linear way, but it is not linear at all. The closest understanding of what spacetime could be observed as is a branching array of 4th dimensional cymatic quantum waves propagating as bubbles when using a 3rd dimensional cross section.
We have nothing to lose from listening, so yes to SETI. However, I don’t think we’re at a point where we can make an informed decision on METI, and as such, we should play it safe until know better. If we do stand to benefit from METI, we’ll be able to figure out out eventually with more information, but if we find out METI is a bad idea and we sent out broadcasts anyway, then we’ll certainly regret our haste.

Peace & war. . . . . particle or wave. . . . . the answer is not one or another. . . . .
Great ending about the human experience of confirmation bias mainly pushed on by society. Did not expect that.
you should try to make your own really big telescope and send it to space i believe you could do it and it would be so cool
We should not be broadcasting any signals purposely calling to potential alien life. Our greatest ally in survival historically has been fear. Fear keeps us alive. We have no way of knowing if anybody is friendly, so we should assume they are not until we have more information. Dip your toe in the water before you jump in.

Ok, that's enough internet for today.
How easily could we with current technologies detect a civilization on the opposite side of the moon?
In short, Entropy is a bitch.
To me, God being behind the Big Bang, or the infinite cycling universe, is the brute fact that halts this question. God is outside the universe and our plane of existence, and therefore outside the bounds of our universe’s reasoning of causality and even linear time itself. So, perhaps extracting oneself from this universe or plane of existence entirely removes the need to provide yet another causal relationship.
I am sorry about Gray's passing. We lost a brilliant mind, but he has certainly inspired us and the next generation of Scientist.
