Then bring it into the now. Bring back that love. As the video says, lamenting on time traveling, it's really us, our innate weird thought we can roll back time, our dwelling the past, makes us have a miserable present and even more miserable future. Work on bringing back or making that atmosphere similar and even better than you recall 2012 being.

@normjohn217 Like so many millions, or billions of trees or trillions of plankton that live and die, and nobody notice any particular one of them fall or die or ever be alive in the first place.

The greatest catastrophe that is unavoidable is Yellow Stone or other Caldera becoming volcanic and collapsing. The world wouldn't end. But it would become very grizzly as it would result in a volcanic winter that would last a couple years causing global crop failures leading to famine that would cause a breakdown in civil order. Even if managed the best possible the most optimistic death count would be 25% of the human population. The most likely result if war and civil unrest essentially cause social order to be a patchwork of warlords, we're looking at 50% to 75% of the worlds population over the span of 3 years dying; vast amount of technology likely forgotten or not understandable a new dark age. Very similar to the result of mutually assured destruction full nuclear exchange between the nuclear powers... but in that case it would happen so abrupt that technology loss would be accelerated... no time to store data in centralized locations, and many data storage that's not on paper or protected against EM pulses would be destroyed. And solid state flash drives and regular mechanical hard drive storage space only lasts for so long, about 100 years or so before the data becomes corrupted and lost forever. So the world might not end even in the next 100,000 to 1 million years. But between that time there will be at least one or two or even three or more moments in time that will make it seem like it's the end of humanity.

It's a private company but it has: 1) gotten loans from the government both Space X and Tesla. 2) Gets government contracts, particularly Space X, in fact that it's bread and butter, without such it wouldn't have enough funding to do much. 3) Receives assistance at various NASA locations for its launches. 4) Has received various subsidies and both direct tax credits or through effective carbon credits that are awarded by states and other governments, these carbon credits are required to be purchased by other vehicle manufacturers in order to avoid even higher fees; Tesla sells these carbon credits to the vehicle manufacturers. Without government requiring and giving carbon credits, a subsidy, Tesla would never have any type of profit at all. Last profit was only because it sold just in the last quart $482 million in carbon credits. "To put that in perspective, regulatory credit sales were greater than the company’s free cash flow and amounted to four times Tesla’s $104 million of net profit for the quarter." So, it's private receiving lots of subsidies from governments. I'm mostly okay with this. WE have to move away from fossil fuels. Do I think Tesla is the answer... maybe.... but I'm thinking more on H2 fuel cells, when Wendelstein 7x or ITER fusion reactors or LFTR fission reactors are built up... making electricity super cheap thus electrolysis cheap, and manufacture of H2 from water is then super cheap and carbon neutral and done at home and at stations, no transporting the fuel. Lithium and cobalt that make up batteries are extremely expensive and certainly not carbon neutral mining such material. And it takes about 140 pounds each of the rare substance. Lithium is 5 times more rare than copper in the earth's crust. So H2 fuel cell cars are more practical... and they refuel faster. Both battery and H2 cars at present have safety issues though, but they can be resolved through engineering. With cheap electrolysis, other longer hydro carbon based fuels can be synthesized that don't ad CO2 to the atmosphere too; as well as materials that can be synthesized. But changing to these technologies will requiring planning, ie subsidies. Just as building highways and interstate freeways and sewers and electrical grids and power plants and ports etc. have in the past and continue to today. Unless you want to live in a dystopia shit hole where most people live in slums with a few small conclaves of elites hiding behind walls aka gated communities.

Was hoping would continue to the end of the sun and the creation of the nebula. Usually a spectacular colorful shapes of gases with a white dwarf at its center, a solar tombstone. That even over time will dissipate, collecting among other large nebula clouds to form new solar systems.

@Piaseczno1 If you're wanting faster learning in such concentrated dosing of science, it would actually take a read thru on Wiki or other googling a bit more credible sites... but it would probably take you a longer read than 35 minutes. His slow pace is nice. And his voice is so relaxing. ASMR nice... peaceful and nice... way to get rid of my head ache or last thing to hear again for several time to help me fall asleep. Any time he's guest on various shows or his own, I just have to listen for both the science and the chill. :)

We're in trouble. But not because pilots are human and prone to error. We're in trouble if you think these people are super human or beyond human. WE're in trouble because we blow our tax money on a giant empire building military instead of a universal healthcare system, and instead of a huge housing program to ensure affordability in housing both private borrow to own housing or renting. Instead we blow our tax dollars on a military that can't distinguish a bird from something else. It's flapping its freaking wings. Btw. the UK and Canada both don't have a payroll tax on medicare/medicaid for their system, UK covering essentially everything head to toe, Canada lesser... the version of Federal income tax pays for all their NHS or Canada's system called Medicare that covers everybody. Basically, they pay via federal income tax... get much better coverage and don't have to pay a bogus premium on a bogus insurance program that doesn't cover much and what it does cover comes with massive copays and initial deductibles... Gimmicks like this medical insurance scam in this country is what should make you understand we're in trouble. But since you don't... I KNOW we're in trouble.

No, AI would be not checking the level of understanding of the material. It's okay to have open sources like the book and calculator... this still provides room for the point of the exam... can they use those materials to correctly come up with answers to the questions? AI would be just testing the AI's ability to do it. Not the student. And I've been both an instructor and always a student.

His one about time travel is a tear jerker too.

Recall watching this the first time when it came out... couldn't it just be some dust debris getting in front of it? And that's what it ended up being. But not one and the most likely (boring though) cause.

All money is a ration stamp. To ration for those who are the kings and queens and their toadstools (some times the toadstools get grumpy pants and take turns being top toadstool for a while), and the rest of the peasantry get thrown a few fractions of ration stamps to fight among each other to collect.

The one looks like a bird, you can literally see the wings flapping.

From the side of those who say there must be life elsewhere due to the size of the universe. Even if just 1 in so many galaxies has life, there's so many galaxies that even that diffuse amount of life could be considered a lot.... hundreds of billions of galaxies just in our observable universe, if 1 and every 100 galaxy has life that's still a billion different occurrences of life forms in our observable universe. So when considering the vastness of just the observable universe that is either infinite or finite with the observable universe to the entire universe being in ratio of atom is to the observable universe. Even a finite universe on that scale atom to the observable universe ratio: that's a ridiculously big universe. And if its infinite in size, infinities do funny things like any possibility must happen an infinite times, so the number of lifeforms of more than microbial to large multi-cell life is infinite. Which infinite being never ending number, that's pretty big and full... that being said, it doesn't say the density at all... it could be "dilute" to the point that life only occurs within the radius of 5 observable universes. Due to the universe being so ridiculously large: The question becomes, how dense? And how do we evaluate that density as being scarce or being abundant? We just don't know, as we haven't enough data points for any of those questions yet. But we can make a guess... infinite universe makes it easy, the answer is infinite life forms... finite universe there's a finite answer 1 being a possibility, us; but unlikely given the size of the universe. There is a slight favor in thinking there is definitely life elsewhere in the universe just based on the size, even if the size is finite.

Especially if there is possible means to traverse through time or alternate causal events, it wouldn't exist with our current technology within any of our live times anyways. And I suspect if there is a way to such a thing, it would be incredibly expensive to those people in that era of technology as it is to us to launch into space; probably why you don't notice being in other timelines, no contradictions, nobody showing up with evidence and all proclaiming to be time travelers, events being thwarted that otherwise would have happened. It's just so expensive such operations would be too expensive for the common technologically advance civilization, possibly required an entire galactic or region of galaxy to spend the resources to modify causality. Just as it was as expensive to traverse across the oceans just 300 years prior to our current year. Because of relativity in a nutshell, and how weird quantum mechanics is, causality is "break-able". My suspicions about oddities about QM such as particle duality, especially entanglement, as well as quantum tunneling and virtual particles has to do with the fact these particles and sub-atomic particle indeed move in motion at relativistic speeds, beyond the confines of event horizons, and thus often bust causal chains. Hence to us seem so weird. They are transferring between past and future and present etc. We all are in motion and amidst the mass similar frame of reference. We vary those frames of reference in such small minute amounts, and constantly re-merging with each others frames of reference; that we are bound by casual continuity very firmly. But not completely impossibly. Again, just like going to space, it takes enormous amounts of energy to reach escape velocity of earth, but it is achievable. Time is relative to each frame of reference. Merging frames of reference under low relativistic oscillations well below even slightly noticeable dilation of time and space produces very consistent causal events. When times that are at or very near relativistic frames of reference then merge, all bets are off. And causal events can become blurred or begin to vary in probabilistic ways, just as we observe in quantum mechanics. Time becomes space like, transferable, probably not in just back and forth but in it's version of width too (whatever that means).

Because he acted on a tv show for kids and now the kids are adults. We have a fascination with entertainers to the point of absurdity. Seriously though, sports coaches are in most states the highest paid persons in the each state, along with massive public spending on stadiums. Look at the guy who played a "very smart person" businessman on tv, but his real fortune came from his family trust, and his only real ventures in to business most have been failures ending in lawsuits and billions in debt, so much so he proclaimed he would never risk his own cash fortune in any of his corporate charters. That clown is now our president.

It's actually good quote. Just means, move on. SO many get stuck in the past... past failures and fear to fail again... comfortable in one job and unwilling to try another that could and probably is better in many ways because of something in the past. Really good quote.

It's not just a good quote, it summarizes his entire ending thesis of this video.

@thehusketeers4319 That's if it is impossible to construct mechanisms that make faster than light travel. And in that case, even star travel within our galaxy becomes extreme improbable.
