  • I always thought that people who said to tap on the top of a shaken can of soda or beer to keep it from exploding were just superstitious :O What are your opinions on making plastic straws and utensils out of plant-based oils?

  • Cheese

  • This is the single most important video on ISchats

  • The Elites are already able to transfer their consciousness to AI. What they need are bodies. Their clones don't last long. Look up Donald Marshall.

  • doesn't mean American, AmeriShould >W<

  • There's a way around this, at least in theory: Consider that the universe would be created simultaneously, so whatever direction you are looking the universe is more or less uniform. If speed of light would be largely different in different directions we would see very different distant things in those directions.

  • Why does anyone listen to this guy?

  • I guarantee you that the US would militarize this

  • Darling, why is our bathroom so big? - I had to put the infinite Penrose Tiling somewhere! Great and enlightening video, as always.

  • Well, I guess I have a horrible mind.

  • i know one importance to know... if one way is infinitely faster, meaning the cap of light speed is infinite and we can be faster than light one way. Also why not sync the clock close together and stay there rather than putting the other one 1km away, sure the numbers may be ultra small but i believe its doable to measure

  • So is that weakening of the magnetic field the reason for global warming?

  • Helical* not heeelical.

  • This is gonna be a new tag in Rule 34 soon...

  • A super hurricane will rip through Florida then blast up the coast all the to Maine.

  • Surely this could be utilised in avalanche situations.

  • I have a question then, how fast does the spacetime curvature travel? How long would it take for us to feel the gravitation difference if the sun would just disappear? Well I assume something like disappearing entirely is kinda surreal, so maybe it is not a case?

  • Ok but no

  • Can't wait for some of e-girls shoving this up into their asses and dies by choking

  • This robot is series invention it could save poor children who fell into borewell. Yes it is shame that children fell into borewell and sad news is this is still happening in 2021.

  • Reminds me of slime mold

  • I wish I could like this video 5 times at least 👌🏻❤️🤘🏻

  • I wont be surprised if this guy, one day, accepts the earth-flat theory.

  • 4:18 4:52 This talk of Mass Spectrometers makes me think he got the salt lamp tested at Black Mesa.

  • Could have been a different story in my country as most high schoolers would be familiar with the concept.

  • does this have to do with the ideal gas law pV=nRT where temperature increases with increased pressure causing this ice to melt till the pressure is removed?

  • anti christ !

  • Just curious why or if gravity is part of your equation? Also what about the reflective source is as true as the original emission of light? As a lighting person in the film industry we will bounce light off of many different surfaces. We actually take advantage of it. Even if we use a mirror I know depending on the glass that we do not get an exact replication of light in return.

  • I want data and stories. If there isn't any data, it makes the story hard to believe. If the data isn't presented in a digestible way, I may not fully understand the data.

  • if it's not true for every direction, wouldn't it be likely we'd see differences in lightspeed if we measure and then angle slightly differently and measure again?

  • People are idiots

  • Don’t listen him

  • Only 4.4 million views in years on an honest and sincere knowledge based video! - All misinformation, hate and propaganda video from other channels are standing 10million plus with in a month or 2. Yup we need this vault more than ever.

  • amazing Explanation

  • Soon to come: Robot makes Erectile Disfunction a thing in the past! In other news, fat women destroy robots intended for ED! News at 11

  • Ok, I didn't even take science in school, but here is my harebrained idea: Quantum entanglement. You'll need some quantum particle that gets activated by light (i.e. flips states when hit by a photon). Have the one particle at the start position and the entangled particle with the clock. The clock needs to be activated be a flip in the quantum state of the particle. Two parallel light beams are required that are activated at the same time. One hits the particle at the start, which flips state as does the entangled partner (which also activates the clock). The second beam travels to the clock, and hits the particle there, flipping it and stopping the clock.

  • this creeps me out for some reason the way it moves... *shivers*

  • I enjoyed this. I would have been explicit that "lucky" in this context probably includes avoiding bad luck. The inference in the video is outcomes are determined by a random, unearned gift. I am sure there are examples of this being true, but it's also possible, probably even likely, that those among a highly and equally talented group who achieved the most success avoided setbacks more than won a lottery. Avoiding setbacks is also a skill in many cases, even though it can be quantified as "luck." A focus on situations in which 1 per 1000 are deemed "winners" and everyone else isn't can be very misleading. Yes, fortune/luck -- either having good luck or avoiding bad luck -- will play a role in any extremely selective situation when even tiny random factors are present. That doesn't mean typical outcomes are essentially random, even in games with undeniable random elements. Think about professional poker tournaments -- why do the top players consistently win? It's a competition that's repeated, not once but again and again, with each player having a "restart" on luck at the beginning of each new competition. The same, small group of people consistently win over the long haul due to talent, skill, superior knowledge, fortitude, competitiveness, AND the experience/insight to understand when to avoid a risky situation. Is that "luck?" I would say no, but the answer really depends on the definition of luck in the first place.

  • I think he shouldn't have spoken to really beat the record...

  • These comments should be good.

  • But why would the returning time from B to A be instant? What really changes once the speed of light reaches B that the speed for going back would change?? Light has the same conditions when traveling AB and BA. Only thing that changes is that the connection is established once it first touches B. So would that in any plausable theory be enough for speed of light to change going “back”??

  • this is the ultimate example of, if it works it ain't stupid...

  • Just listen between 11:11 and 11:24 🤣😏

  • Really great episode!

  • Use a quantum computer to teleport information, problem solved. TBH i seriously hope that the speed of light is different, because everything about what we think to know about the universe, including the Big Bang, falls apart.

  • Women in the future will love this...

  • Most of the time I see the window oscillating, but sometimes I can force myself to see it rotating.

  • Please don't light lighters on planes bro

  • porn industries are taking this for considerations.

  • We can now probe the aliens asses back

  • Another minute long video.

  • back when people were scared from microwaves 😂

  • All Smoke n Mirrors

  • Can’t wait till these things take over the world and choke the human race to death :)

  • Alex and Derek, At the 14:15 mark of this video, possibly the “magic” and “fireworks” proved an ample distraction, as it appears that the third term [in the brackets] of the new equation has both an errant exponent and denominator [(x^4)/4 should be (x^5)/5], while the fifth term has an errant denominator [(x^9)/8 should be (x^9)/9]. Math is the purest form of beauty, and this collaborative video is surely a treasure. I hope you take no umbrage in the addressing of this apparent, albeit minor, discrepancy. One question: By adding both the obverse and third dimension to Pascal’s work, has Newton not effectively altered the resultant geometric shape away from that of a simple “triangle” and to more of a point-to-point bipyramid of sorts? ⌲◅ Thank you for all your videos. Your enthusiasm on such a wide variety of subject matter is refreshing, thought-provoking, contagious and most appreciated!

  • DISCLAIMER: I AM A MECHANICAL ENGINEER MAJOR IN COLLEGE, I AM WATCHING A ISchats VIDEO ABOUT THIS, I AM OBVIOUSLY NOT AN EXPERT IN PHYSICS SO THIS MAY HAVE SOME FALTS OR MAY HAVE TO MANY VARIABLES TO BE CONSIDERED AS A WAY TO MEASURE IF TIME HAS A PREFERED DIRECTION OR NOT. Thank you Let the area that you are using be flat, let the area you are using be a vacuum, let the area you are using have no variation gravity. This is not made to measure time but to see if there is a difference What if you do the middle clock thing, moving both clocks away from each other from the middle and measure said dilation. Once you have that number, repeat it to see the average. After you have done that, do it again, shooting from clock (A) to clock (B). This would not be done using time to measure but distance, use two wheels that are the same size to measure the distance, as they roll along the ground to measure how far you are. (it doesn't matter as long as you know where the clocks are) Once you have the time that it takes to get from (A) to (B) then you have the amount of time it takes for light to move in that one way, you can do this more than once, however, less is more as the more you move the clocks around the more likely it is that you introduced variables. Now do the same for the way back, moving the clocks to make sure that the dilation is the same again so that everything is even, then measure the time it takes for light to go from (B) to (A), take away the average you set in the beginning and now you have a number that should be the same as the one from (A) to (B). If these numbers are not the same then light may have a preferred way to go in the universe, if they are the same then more than likely, light is a constant speed. OPINION TIME I do not think that light has a preferred direction, though it may have varying speeds depending on gravity and other variables, I think that it is constant as long as the conditions that it is going through is constant, this is because light is energy, energy can not be destroyed or lost because it is going one way, unless light photons are always spinning in one way. but that is another discussion for someone smarter than me.

  • Wanna know why we don’t use this for incubation is because if you do that people are going to rule 34 it and before you know it we’ll have people showing up to the hospital with this where it shouldn’t be.

  • The long pp project

  • 11:15 this would work so well for oil sands it's crazy to even think that isn't being looked at. Like it would not only be a simple fix to a problem with the oil industry but it woukd also make cleaning up well sites easier as you wouldn't need to take a giant pipe out of the ground.

  • Next challenge: fly a helicopter into a cave on Mars...

  • Plese next video

  • Are they stoned

    • I really suspect Veritisium gets high and makes these videos

  • IMO I feel that he may be one of the Galileos of this era and it’ll take some 400+ years before most will agree. I mean seriously: There are still people that believes Earth is flat so what more can anyone else say/do.

  • A balloon for every hole! All sizes 😂
