  • Population doesn’t decrease, you are modeling the rate of change of the population. If P is the function of population, you are modeling dP/dt, and the solution to this differential equation is a logistic function, which is increasing and bounded by carrying capacity

  • wait so aging is basically Cell Alzheimer's

  • it spread through the Bild? No offence but that's nothing I'd be majorly concerned about. Whether they're big or not (and they are), they don't have a good reputation

  • So gravity is not a FORCE after all. It's a FARCE.

  • It sounds good if you talk about *you* being president or whatever. But each parallel world has its own parallel worlds. The cat isn't just alive or dead, it's also in a world where there was no experiment, and one where there was no Schroedinger. In fact, the likelihood of Schroedinger's existence depends a lot on the timing of his conception, since he could have been someone else entirely, and his parents' meeting, and their respective conceptions, and more than that, a world where there are no humans, and before that, where mammals don't exist, and before that, where life doesn't exist, and ALL of these possibilities have infinite worlds "branching" from them and it's been going on for 13.8 billion years. And someone will say, like in the video, sure, it all adds up, the math covers it. Hey, if you say so.

  • What's good full name??

  • I still don't understand why we accelerate on earth? Is it because earth is accelerating through space and we don't have that frame of reference? Then the direction enertia would change depending on spin of the earth... However everyone has the same direction of enertia, down... So how are we all feeling the downward affect of gravity of it has nothing to do with earths acceleration through space? Or, is this strictly on expanding my definition of "acceleration" on a geodesic?

  • That was pretty exciting. I did some computations, and saw the same pattern. However, for x(k+1) = r * x(k) * (1 - x(k)) formula, it diverges after r = 4. Also, it generates a random sequence, but its far beyond from being uniform; it's distribution has peaks in 0 and 1 and was flat-ish in the middle.

  • It's not You accelerating towards Earth, its the Earth accelerating towards You.

  • Everyone who takes 6th form physics at school learns that Force = Mass x Acceleration. And Gravity is an acceleration. That is what Newton taught us, you don't need to mention Einstein! You must be running-out of things to talk about.

  • wow.great explanation.

  • THE CLEAR, THE FULL, AND THE BALANCED MATHEMATICAL PROOF THAT ELECTROMAGNETISM/ENERGY IS GRAVITY, AS E=MC2 IS F=MA: E=mc2 IS F=ma. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ACCORDINGLY, time DILATION ULTIMATELY proves that electromagnetism/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper understanding of physics/physical experience, AS ELECTROMAGNETISM/energy is gravity. E=mc2 IS F=ma. SO, truly and ultimately, time is NECESSARILY possible/potential AND actual IN BALANCE; AS ELECTROMAGNETISM/energy is gravity. Gravity AND ELECTROMAGNETISM/ENERGY are linked AND BALANCED opposites, AS electromagnetism/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Objects fall at the SAME RATE (neglecting air resistance, of course), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, E=mc2 IS F=ma. Gravity IS ELECTROMAGNETISM/ENERGY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. It ALL CLEARLY makes perfect sense. Notice that the stars AND PLANETS are POINTS in the night sky. MOREOVER, A PHOTON may be placed at the center of what is THE SUN; AS the reduction of SPACE is offset by (or BALANCED with) the speed of light; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 IS DIRECTLY and fundamentally derived from F=ma. (INDEED, BALANCE AND completeness go hand in hand.) E=mc2 IS F=ma. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The BALANCE of being AND EXPERIENCE is essential. Thoughts are INVISIBLE. Carefully consider the man who is standing on what is the Earth/ground. LOOK around. THINK about it. (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.) Put it ALL together. GREAT !!! E=mc2 IS F=ma. The INTEGRATED EXTENSIVENESS of THOUGHT (AND DESCRIPTION) is improved in the truly superior mind. E=mc2 IS F=ma. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ACCORDINGLY, the rotation of WHAT IS THE MOON MATCHES it's revolution. THIS also explains the perpetual motion of what is THE MOON. SO, gravity IS ELECTROMAGNETISM/ENERGY. By Frank DiMeglio

  • Think about something humanity hasn’t figured out yet, come up with a complex and convincing conspiracy theory, get it published. *Scientist*

  • The flatearthers will have a field day with this.

  • WOW. Just, wow. My whole life is a lie. My whole time doing those math in physic class during middle and high school were wrong.

  • "Do you even lift"

  • 4:50 I was a little confused at first when I saw two veritasiums

  • Lets say that the earth is accelerating upwards with the north pole being the "tip" why do people on Antarctica not fall off?

  • *I have a question* My question is; When you blasted off in your spaceship, how did the camera keep up with you all the way out into space?

  • 3:15 this would be a beautiful wallpaper

  • Oh wait wait wait...I see what you did there! Exposed! Nyahaha 😂

  • Isn't a spinning black hole a paradox? I understand that they do rotate but.. How can an object that has infinite density and take up no space rotate? You have to have a center and outer surface to create a spin right? When your talking about a singularity your talking about an object that doesn't have an area.. so how does it spin? This is where I'd argue that black holes do give us clues to their nature.. I suspect that they're truly dark stars.. I don't think they truly collapse completely.. And if they don't, then they most certainly can spin,

  • Wait, so you are saying ONLY 50% people have dandruff, and it is a condition. FUKKKK

  • If you want to wear masks the rest of your life and throw away your freedom vote for Biden. I approve this message.

  • That's a lot of Gucci banana

  • You should encourage people to bookmark your home page and come back every week! Edit: I see you mentioned the bell. That would work as well. I also like the discussion about "long term." What is 30 min of watch time worth if that person gets frustrated that they watched so long and chooses not to come back as a result? What if they are shown more clickbait and less education and that causes them to be less inspired and more so temporarily entertained by youtube content, and causes their view to be of lower value compared to the view of someone who is getting educational content that informs them and even helps them become successful in their job and their career? Those may be some long-term existential ideas, but I think it's fair to think about when you consider that many people spend on the order of hours per day on youtube. It really has an effect, and that effect can be positive or negative; long-term, I think it's more beneficial to all involved for the effect to be positive.

  • We can't go to space there is no space there is a huge sky ice wall in flat earth What you seeing blue sky it is not a ozone layer it is a huge sky ice We are trap in this world there is no Galaxy there is no Mikey way there is only 1sun 2 moon and 1 flat earth See the 18th century flat earth map If you try to reach the sky you will be burn on the top God is there There are planets do you think I am fool Read the Old Testament new testament

  • you changed the title for this video like 3 times

  • 9:23 Did Derek just eat kiwi with the skin on?

  • anyone here from science class👀

  • "And in this video, I will prove it to you by blasting off into outer space." Boy, that escalated quickly.

  • I dont get the 8:00 part that how we are not an inertial observer. After that in 40 seconds that he explained--that's a lot to take. Hence I didn't get the video. Can anyone care to explain?

  • There are no ads nice..

  • The scientific method is not trying to find a proof, but trying to deny the hypothesis. If it can not be denied then the further experiments are being introduced to study it further...

  • That was a great scream by the way

  • I hope the other twin mouse also got treated to become young again

  • Gravity is condensed time.

  • He really just had to slip that “powerhouse of the cell” in there

  • What makes a melonball bounce? (A melon ball bounce?) A melonball bounce! What makes a melonball bounce? The line-taut tension of Line-X!

  • Great video! It may be emphasized that we are talking about spacetime, not space only. Nobody is stationary in spacetime because at least we move through time. It goes like that, if we do not experience any force, the path we take is a straight line, but only relative to spacetime. If people on earth surface, in all directions, are "accelerating in spacetime" but also "stationary" relative to earth, it means that space itself is curved towards earth with the increase of time. Also, this video is about relativity, so it is unnecessary to mess it up with other theories. In science it is always possible to try to find a better theory. It doesn't in any way mean the video is mistaken.

  • Idk why but i think of bloodshot when I see this🤣

  • Funny your graph starts in the 80’s, really? For a world millions of years old and a few decades is what you measure? How about going back 1888, or even further? And another question, why haven’t the climate alarmist accepted the facts of nuclear as the only option, if you truly want to cut CO2 in the worlds climate? This CO2 push is BS.

  • wtf....

  • Derek: What do you think about this idea about light, sounds crazy but have sense, this is the proposal: If you drop a rock on water, you will see waves traveling, it is not the water what is traveling, it is the energy, although, we know the water itself could be moved or displaced… So, with the light it is the same effect: the light is always there, the light really doesn’t travel, because it is inherent to space-time. Who is traveling? Is the energy who travels. The "already existent light" only needs to be "energized" to be seen. So, we are not seeing the light travels through the space, we are seeing the Energy traveling through the space-time-light dimension... The space time grid it is included on light (light as a dimension).

  • Very thought provoking. Well done as a video and content. Thanks for publishing it. But I still think that gravity is a 'force', GR and Einstein are right but it is only a mathematical similarity between acceleration and gravitation. Good Luck.

  • I still wonder about the tendency to say things like, "condition A existed, therefore creature X developed this adaptation." That isn't how evolution is supposed to work. A creature doesn't adapt mindfully to its environment. So what gives? Why are we using this terminology to describe adaptation? Is it possible that our ideas about evolution are inconsistent and scientifically unsound?

  • I kinda get the space example but not the falling off the roof. The man isn't moving and than he is...and no Earth gravity is not the same as inertia. And a ball falls faster than a balloon. If two identical objects fall at the same rate, where is the mystery?

  • Imagine how beautiful it would be if the marble flat exterior was still there...

  • ok this bothered me that you used actual paper when a marker board would suffice.

  • I feel bad for the person who won the SXSW tickets.

  • HUGE fan of your videos! Great content as always.. can you tell me what is that signature background music in most of your videos? I love it.

  • Vsauce be like: hold my beer.

  • Wait, if it repels water how the hell did he wash it off?

  • 5:51 *Bird Dies* Me: Bruh

  • 55 cancri e look it up

  • The guy at 0:27 was right! 😅

  • But why does spacetime stretch towards earth instead of scrunching up around it? If space stretches itself towards earth then is there a parallel model we are familiar with that we can use as an analogy? Previously I had thought it could be likened to a person moving through a crowd of people. Since you can't just phase through each other, the crowd moves for you and scrunches up the tightest closest to you. But this doesn't seem to be how spacetime behaves. It seems to be the opposite; space seems to stretch towards the massive object. But why? Not why as in "why everything", but why as in there's gotta be some "local" example of this behavior that we can use to make sense of it. Something were familiar with that we can point at and say "oh it's like this".

  • soooooo the helicopter actually moving upward 9.8m/second? that mean helicopter actually floating not flying.. when u throw something up, they fall because of they losing they speed and earth able to catch up? but in the ocean we fall much more slower that because the water slowing us? some sort of drag or just buoyancy thing bruh..

  • Flat Earthers: Its clearly CGI!

  • Did anybody notice Ethanol floating next to him at 3:24 ?
