Veritasium

Ahh. Can't figure out how to reply here so to brachmed Yeah things can go that fast. Veritaium posted a vid where to the LHC and talked to the guys who proved the higgs boson existed. They collided 2 protons moving at 99.99% the speed of light(this caused the protons to "create" other things from the standard model) several times. I'm not sure if the same with larger objects but a neutron star's rotational speed at escape velocity can go as fast a third of the speed of light.

This is such a great channel. Now I know you love misconceptions, so I have one of the biggest ones for you, The difference between centripetal force and centrifugal force. Most people use the latter when they are usually describing centripetal force. PLEASE MAKE A VIDEO ON THIS!!!!

On the test with the copper tube and the magnet does the copper tube get heavier when the magnet drops?

What is your day job? Thanks for the great videos! As an engineer the wonder you demonstrate in people's faces reminds me of why I got into science. Learning about how stuff works is just cool!

On the video about the world's roundest object, the portuguese subtitles at 10:00 claim the redefinition of the kilogram could happen "as early as 2040" (LOL!). Any way to correct that to 2014?

Would you make a video about atomic transitions and the physics of flames? I am a wildland firefighter and would love to study the science of fire! Your ability to make complex scientific knowledge fun and understandable would make a great video about the physics behind fires and I would be thrilled to blow up the minds of my rookie firefighters.

I know that everything that has mass can't reach the speed of light, because you would need an infinite amount of energy. But what if you just want to reach a fraction of that, maybe like 10%? What amount of energy would you need to accelerate an object that weights maybe 1 kilogram to this velocity. I've read that the Voyager 1 moves at 61,380km/h which is around 17km/s and still around ~17500 times slower that the speed of light. Would it be possible to reach 99% of the speed of light? You wouldn't need an infinite amount of energy for that, would you?

hey there, this has probably been asked before but... please, make a video about quantum physics for dummies. I would appreciate it!

Hi, could you do a video on the theoretical "Brain in a vat" and it's practical implications? Could an individual become theoretically immortal if the brain is kept in good health? If a brain is transplanted and is kept in good health could the individual (the brain) be kept alive by changing bodies each time a body could no longer continue to live? I have posted a similar question on Vsauce and I think it would be amazing if even one of you could do a video on this, but even better if you could trade theories and collaborate on this. Thanks.

Are you Canadian? Awesome contents you've got here mate!

I have a question I've been thinking for a few days now. How good can a telescope ever get? Is there a limit to how much we can zoom in, ever? If we ever manage to travel faster than light, would we ever be able to go 2500 light years away, and through an amazingly advanced telescope look back to Earth and actually see the face of Archimedes, for example?

Thanks for the awesome videos!

What about a spinning rectangular prism with dimensions similar to that of a smart phone. The prism has three axis: let the longest one be x-axis, the mid length be y-axis and the shortest one be z-axis. When you spin the prism in the air either about the z-axis (like 360 pop shuv-it) or about the x-axis (like kickflip) it spins just as you expect. But when you spin it about its y-axis (like dolphin flip) it does not spin straight but rather wobbles as if wanting to also spin about its x-axis. Why is that?

Derek, I've been wondering, if a box with flat sides were to be sunk to a flat bottom of a container full of water, will it still be affected by buoyancy force? *by flat I mean really flat, no friction, so they will just completely stick to each other without any microscopic hills and valleys whatsoever. To answer that, I also need to ask if buoyancy works by pushing the the submerged things from below, or rather pulling it from anywhere around it? Thanks in advance :)

on a tangent,....perhaps some "Sci-Fi esque" material? like translight travel, or teleportation? i realize its cliche, and i apologize for being that "oOHHooHH can i haz dis plox" channel invader guy, but i think anybody can like sci-fi, i know i will.

quarks.....everyone loves quarks.....PLEASE do the quarks some service would love a "quarky" video.... (physics pun intended) :)

is it possible to contain plasma in a lightbulb and have a small egough power supply that you could throw it and set fire to a plywood man cut out?

Have you considered doing an episode on biological immortality? Maybe going on to how possible/impossible it is for us complex multicellular organisms?

Awesome channel mate, quick comment for the slow mo stuff, see if you can get hold of either the slow mo guys or destin from smarter everyday, i know you guys all live very far apart but you could film a load of video's and release them as a special :)

I'd like to see a video on why the Earth doesn't maintain a constant distance of orbit relative to the Sun? I understand the principle/fact that when the Sun pulls us in we speed up and therefor get pushed out back, this is what keeps us in orbit the two forces constantly acting. However shouldn't we then maintain a perfect constant distance to the Sun? To me the fact that we don't indicates that one force must get slightly stronger at one point and then the opposing force eventually gets stronger. Is this correct?

Vsauce

why do city lights project onto the cloudy night sky in the color Red and not any other color?

ok so new to the channel, i apologize for this being so old but, in your video about the misconceptions about falling objects I think there may be an error, or at least something was not mentioned.......not trying to pick, but this all depends upon how far you drop them ;) each object has a critical velocity depending upon its mass, an object dropped will continue to accelerate (i think its like 32 feet per second per second) until it reaches its critical velocity according to its mass at which point it stops accelerating, since the 5kb ball has more mass it would accelerate for a longer period of time then the basket ball, if dropped from a high enough altitude..correct me if i'm wrong please...I would have provided a link from nasa's website explaining this in greater detail but it was down at the time :(

is it possible to thorw all garbage into the volcano ?

I think your kanal is smart and good. For this I am a new pal, and member of your station, OK? Your little amigo, Achilles

Could you do a video on density? For example, does a comet falling to earth (or the sun--more interesting) increase it's density? Or does it increase both mass and volume proportionally so there is no change? Pleeeeeease do a video on this!

I would like to know some more about perpetual motion. I heard that at the quantum level it is possible. Why is that?

Hey That Was Awesome.

@lexmarkbites I am reading these comments from time to time, but it is annoying because I can't reply to each comment...

your videos make me miss sydney so much, i started following your channel since my time in uni in 2011

Derek, I'm pretty sure the roundest objects made are the gyroscopes in the gravity probe b satellite circling the earth. If one of those spheres were scaled to the size of the earth, the tallest mountains and deepest ocean trench would measure only 2.4 m (8 ft) high.

You have a video saying that gravity doesn't affect rotation of a planet. I'm very suspicious of this statement. If that's the case why does tidal locking exist?

you are not reading these comments.

You should do a video on friction. For example when a tire rotates and pushes a car forward, some people seem to believe that the more area in contact with the ground the more friction there is. I think friction force only depends on the friction coefficients but a video on this could clear things up for everyone. I believe area only affects the pressure at the area in contact with the floor. For solids though, since for fluids area does matter.

Been watching a short while, learning a lot, love the channel! Please keep up the excellent work.

in lieu of watching the spinning tube video i was wondering about spinning coins. if you spin a coin and observe it from the side you see the side that will end up showing face up when it stops, this is visible from all angles and seeing as the velocity doesn't change from side to side would you know why a coin being spun has a visible side that ends up tops, this is an argument between my friend and I and we would love to know, thank you. p.s i love your channel

make a video on black hole please

i send you a mail, cause it wouldn't work in here... hope that you'll see it! You have a good job in here! nicely done!!!

Dude, I just started watching different videos of yours, and you are a boss! I love science and teaching, so it's awesome to see someone finding better ways to teach science. Respect!

please go back to the old youtube layout, please!

DO ELECTRONS EVER STOP ORBITING THE NUCLEUS. I READ THAT THEY DO NOT STOP ORBITING. IF THE ORBITS OF THE ELECTRONS ARE SHARED TO MAKE CHEMICAL BONDS WHERE DO THEY GET THE ENERY TO HOLD THE BOND ORBIT.

THE WHEELS ON A BIKE AND MOTORCYCLE ACT AS GYROS. THE FASTER THEY SPIN THE MORE STABLE THE BIKE BECOMES. SO SFT SEE IT FEEL IT THINK IT THEN TAKE OFF FAST SO U WILL NOT FALL OVER AT THE START.

mahmound ahmed...it is because the wheels spinning forward or backward produce torque pushing from each side of the wheel which acts as a stabilizing force; this is why a top spins.

would u please answer this (why it is easier to balance yourself while you are moving with the bicycle than not moving)

Can you do a video showing how to measure a year

Hey Derek! People seem to have a lot of misconception of nuclear energy and nuclear fusion energy. Can you do a video about them? (How we produce energy from nuclear fission and fusion, although fusion is not complete yet)

do a video about entropy

I will be very thankful to you if you would answer this:Why do broken magnets repel? I don't know whether it is a big question or a silly one, but I found no perfect answer to this on the internet. Thanks!

Please make some videos on Chaos!!!

Thanks for a totally awesome, informative, captivating, challenging and inspirational contribution to a better understanding of science. Keep up the magnificent work!
