    NSA hired him immediately afterwards

  2. Ben T

    Where was this video when I was in uni... jeez... 10 years too late.. haha..

  3. Jatin Saharan

    you forgot youthoob ads crisis

  4. Miktad Bahadır TÜRK

    thanks a lot man for everything you done

  5. Pula Vijaya

    Is world an illusion make a video sir

  6. Olusegun Onanuga

    No wonder pandemics and conspiracies tend to spread rather quickly... Hope this is one of the tools that contact tracers can use to help curtail the spread of covid-19.

    But first. I’m not even gona take a sip of this cup of liberal lies.

    If light was instantaneous going in one direction, that would mean stars we are seeing in that direction we are seeing in real-time. That means that, since there aren't infinitely many stars littering the sky in that direction, we are effectively seeing the edge of the universe, thus proving the universe is finite. And the corollary to this is that stars we are seeing in the opposite direction which we thought were 46 billion light-years away are actually only 23 billion light-years away, so we are only seeing half of the universe that we thought we were in that direction. What if, in that longer direction, all the radio waves we've been broadcasting into space are being received by an alien civilization in real-time, but their response is taking billions of years to reach us. Maybe they just think we've been complete and total jerks to be ignoring them all this time and now they are coming to kill us to make us finally shut up and they can get the first quiet night's sleep they've had in over a hundred years.

    send light around a black hole such that it is in a perfect circle and measure it from the start to its arrival after the trip around it , the space around the black hole is curved and the light will travel in this circle in a uniform space time curvature , because if not it will fall in the black hole . This method can be used in my opinion

  12. Hank Storm

    it baffles me people listen to this lunatic, he is a cartoon caricature of a villain that spouts nothing but utter nonsense.

  13. Cashew Nuttel

    Thank you for giving me the answer in the thumbnail. Now I don't have to waste 20 minutes of my life looking for an answer to a question that could be answered in... less than 30 seconds?

  14. Peacocks & Polar Bears

    This is insane. I've never seen something visualized like this.

  15. Jay

    i just found this channel, and i started to like it so much. thanks for making all these videos for us.

  16. George Pirpiris

    Why does this have 70 million views???

  17. Jamie Roberts

    Dude.. I've been able to see those stripes on myself while on hallucinogens before!! Not that I'm proud, we all experiment at a certain age and I'm a normal bird watching mom now.. but! I've seen those stripes on myself before. Crazy.

  18. kosmikmusa

    This happens with sound frequencies too?

  19. Toby Redfern

    What about syncing the clocks in the middle and moving them to either side after

  20. Remote Viewer 1

    Fascinating. Who knew?

  21. Jatin Saharan

    ask the one who is running the simulation of this universe

  22. Zero De Farnel

    sorry but someone has already tried to measure the speed of light. The result was that some particles were faster than the theoretical and others were slower. Then the researcher lost her job. this was measured with a particle accelerator.

  23. Peacocks & Polar Bears

    Uh. Start two cesium/rubidium/mechanic/chemical clocks on earth. Start laser or radio modulation with clocking data broadcast to Mars. Take one clock, go to Mars. Start two clocks there also. Three clocks on Mars. Broadcast from Mars to Earth over a satellite or retrans connection for clocking data. Run real time experiments back and forth. Leave Mars, take clock and one of the new clocks and leave to Earth. Leave. Compare clock time when you get to and from. Presto.

    1. Peacocks & Polar Bears

      Really. If these clocks broadcast their clocking data constantly and went planet to could easily perform clocking experiments but there is the challenge of space travel at the moment. If we could drive down the road this would be done and over.

  24. Cre8NFaces

    He's a Murderer and planned this. He and FAUCI want DEPOPULATION & he's not a damn doctor! He makes money off these "vaccine experiments"

  25. Al Rivera

    Apple does this now by prohibiting repair shops purchase of parts and opposing right to repair laws.

  26. FaultyTwo

    Alternate Video Title: 'Capitalism ruins everything."

  27. Paul

    I feel sure that clocks could be synchronized, then moved apart. Time dilation can be calculated based on speed and distance traveled then the clocks are readjusted with an offset.

  28. P Vangastel

    Did the 2nd bunny actually fall on its feet?!

  29. William Jones

    Hey, were not going to use that commie metric system. If God wanted us to use the metric system he would of made water freeze at 0 and boil at 100. Wait, what?

  30. shawnh

    ALso needs a vacuum to control conditions of the experiment. Also does a spectrum in infrared move faster than on in the blue or green spectrum since size and the energy of the photon make it faster or slower so you'd need to see if in each spectrum band the same or along the spectrum from the weakest to the strongest color of photon and see if they are measurably faster or slower and do the photons bouncing bump into the ones that are now going into the return so at the impact point are photons slowing as they go through or bye each other. Do photons like water have cohesion so do the ones on the to trip drag the ones on the return trip like a magnet effect another field causing flex like gravity bends. I'm a layman and these are just questions I think might have a consideration.

  31. Andrew Godly

    The questions that always have bothered me is what even is "hard work" and "talent"? Why should anyone value them? Why does success have to be fame and fortune? Why should anyone care about being successful? Why should society be structured around an arbitrary concept of merit? Who gets to define the "merit"? What gave them the authority to decide who's deserving and who isn't? Why can't a humble couch potato be just as deserving of respect and fortune as anyone else?

  32. Ten Deepfake

    Love science.

  33. Micky Mavros

    Same freaky effect as when you use a 230mm angle grinder. The grinder seems to have a mind of it's own.

  34. DR BROWN

    Does it maintain the same speed when it bends?.. will gravity speed it up?....what type of light? Each color has is own length of much energy in light source?... To many variables....

  35. Geina Vella

    Rofl 😂 360 million years ago

  36. Samer Mazahreh

    Man bringing up this topic alone is a feat, but explaining it to this level of straightforwardness, detail, & clarity is just wow

  37. Benjamin D

    Except the LED bulbs have power supply bases that die on a schedule. So really we're back to square one, with the low quality LED bulbs it seems we're back to the cartel, and no way to discern a quality long-lasting light source from a low quality one. I for one would pay double if I knew the bulb would last 15 years!

  38. korteks visceralzen

    Thanks. I love this channel. No one explains this stuff.

  39. Sarah Conner

    CLICKBAIT!! Many people have done the experiment of the speed of light!!!

  40. John Watkins

    It has been said that “luck is simply when preparation meets opportunity”!

  41. Isaac

    Really Great video. Would you do us a favor and talk about the safety of the radioactive water Japan is planning to dump into the ocean? Really really concerned

  42. Naman Jain

    No it's not it is the speed of causality galaxies far away (outside the hubble horizon to be precise) are going well beyond the speed of light but they still affect us via there light or gravitational wvaes which travel at C

  43. Justin Popa

    Thank you! That was cool!

  44. David Shakespeare

    Watch pentagon is the best a gone

  45. Rodro M

    Be uncomfortably Hot or cold Someone living in the desert - are you challenging me?

  46. Abhishek Prajapati

    Nice work derek

  47. Antony

    Why use light to synchronize the clock? Why not use sound wave? Or ripples in water?

  48. Vinod Adwani

    Anyone thought of breaking that bulb and running away, or it's just me?

  49. John Smith

    10:10 if you have x=1 (before you times both sides by (1+x) You get 1/2 = 1-1+1-1+1-1+1-1+1-1+1-1+1...... Huh? What did I do wrong cos don't these term cancel leaving 0 or 1 - I'm confused.

  50. alicia

    In the past, vitamin B12 used to exist in soil. This meant that farmers would get this vitamin from their plants. Now that the soil is depleted in this, slaughterhouses stay adding tons of Vitamin B12 supplements to the fodder. That is the only reason why meat contains vitamin B12, so I hate when people say that taking a supplement is considered “fake”.

  51. Lord dra Walker

    Smart choice to interview the guy most responsible for orchestrating the current crisis. Of course it's going to do with something related to his new vaccine empire. Bill Gates should be behind bars doing 100 consecutive life sentences,

  52. Jan Smidt

    with the new slow motion camera you should be able to measure the time it take between two points. in their video of the slow mo guys it toke around 1000-1200 pico seconds for the light to pass through a 600ml water bottle. if we would have measurements of the bottle we could calculate

  53. NitroThe X

    I dont care, I like seeing a glowing rock.

  54. Leo van den Brandt

    When you’ve read the HP books and realize just how awesome his YT name is...

  55. RawrItsTayL0R

    why do you have a flip knife? isn't that illegal? wTF

  56. Toxic Potato

    You solved the problem 2:15 into your own video. "You might think you can just subtract that time delay, but IT IS EQUAL TO THE TIME IT TAKES LIGHT TO TRAVEL 1KM!"

  57. mesa620

    Isn’t the universe just a marble for an alien like in MIB...

  58. 60 secondfrenzy

    Why was this recommended to me when I was about to sleep

  59. phenom

    Couldn't you hook up a wire to both clocks without moving them and connect them to a single button to activate them then shoot the light (Edit to clarify) If we are trying to determine if a signal is faster in one direction than the other then if the wire lengths are the same then if you could preform this experiment in space an a plane then by conducting the experiment in different directions and comparing the data we could tell I think.

  60. Jukebox300

    The three blind mice should have just gotten gene therapy. Then they probably wouldn't have lost their tails.

  61. David D

    It's almost as if Capitalism is inherently evil what a revelation

  62. Mitch Ishii

    Me an intellectual: 6:30 huh, nice smiley face

  63. Max B

    Max was here

  64. jazz vir

    You posted this video during all this vaccine thing going on😑

  65. James Edmond

    Tell the guy that is falling off a tall building, that gravity is not a force.

  66. Aniruddha Kshirsagar

    finally i can do backflip without any effort

  67. Fourtii

    Yet again, another story centred around capitalism, surprise duh🙄 But again highly insightful video👍

  68. Колян самоучка

    Получается рассенхронизация часов до средней точки будет ровнятся половине пути земля-марс и если луч пройдёт через центр то при возвращению можно вычеслить скорость исходя из данных половины пути и рассенхронизацию (тоесть 5 минут от Земли до центра, 5минут от центра до Марса и обратно)......

  69. Boyd Jensen

    Ok, so I have thought aboot this before. Lets animate a photon, and let it speak. So you look at a star emanating light (obviously.) Now you have a conversation with the photon who just lit up your retina/brain/whatever. So, I now being you, ask the photon, gee so glad to see you (to the photon.) It took a million years for you to get to earth, I exclaim, according to how far away you are. The photon protests violently, bullshot, I just left, where have you been for the last million years., stupid earthling.

  70. Kinanti DR

    4. Rails?

  71. Arturo Dela Cruz iii

    just make a 2 clocks stop then initial clock start as the light start to travel and the other clock trigger when light pass through

  72. Me

    Rick and Morty have this figured out

  73. Moses Racal

    What if the great filter is just the speed of light?

  74. Jukebox300

    7:17 Such a good question

  75. Rage of ores

    the perfect vacuum doesnt exist.

  76. Tucsonan Dude

    How many of you science nerds have a copper tube and some neo magnets to impress your friends...a la Lenz Effect?

  77. Oliver Barber

    “The whole is more than the sum of the parts” -19:19ish. I like to hear this. I believe we have souls and individuality. There’s a reason consciousness doesn’t make sense when it’s speculated upon from a perspective that omits the existence of God. We are who He made us and I am not you nor you me. I am who He says I am and science can only prove that. What power does the earth have above the Lord. Oh, how great He is that He should make this world and all of existence, which should strive for entropy, synchronize in ways specifically designed to support us. He didn’t make everything then decide to put us in it. He made all of existence just to have us and know us and that we may know Him!

  78. Jason Peters

    You mean like the CCP and their Wuhan flu Billy? I can't stomach listening to the man that has all the answers. 🙄. How TF does a software engineer become the face and voice of our salvation? Oh boy.

  79. carso antonio

    SO wait, would that mean that we can theorically travel at infinite speed, because that would actually be great

  80. 진실추적

    Good morning I am a young man in Korea Korea is now entering an aging society If you introduce it to Korea from the beautiful country of the United States, please tell us some things that can help the weak and the elderly and help Korea. Korea is severely corrupted by corruption and corruption. Please help Korea.
