Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek answers to these questions. Despite the best efforts of scientists (and the help of the biggest machine on the planet), we may never be able to explain all the weird features of nature. Is this the end of physics? Learn more in this fascinating talk about the latest research into the secret structure of the universe.

    @geobla66007 years ago It' s refreshing to see such honesty in this field of science.
    to actually admit the magnitude of this lack of matter means to the laws of physics there' s anthat the other laws or constants are also another insurmountable problem.
    i watched another ted' s talk done by a different physicist involved with the research done at hadron. His name was james beacham and his approach was more on the typical side, which is to minimize the problem and present it as just a small setback.
    he went on to explain how the press got hold of some information that had accidentally (leaked out? And how the media blew it out of proportion. Media will tend to do that when their told that. Of course he blames the media and not the 500 and some papers that were written by some of the scientists involved.
    he also mentioned that if they don' t have success with the hadron collider, over 30 years to construct with 10' s of years of man hours and billions of dollars latter) we' ll just have to wait until china builds even a larger one.
    anyway, it' s nice to see information presented as it should be honestly by scientists like harry

    @geobla66006 years ago It' s a pleasure to see this type of honest assessment made by a scientist directly involved
    with the research at the hadron collider. you can see by some of the other comments prior to mine that theirs disappointment in
    both his assessment ( and over 500 other full time researchers and 10' s of part time researchers ) in the limited amount of matter that has been found.
    on a previous video made at the world science festival, the lead physicists in charge
    of the cern project was quite surprised at minimal findings up to that point.
    they can take about 600, 0, 0 readings per second and thepower has been significantly updated twice.
    this creates a real problem for all the theories on the origins of the universe other then
    possible the multiverse which very few scientists think has any merit.
    but no need for concern. Most people have forgotten the multitude and magnitude of the
    claims which were made over a decade leading up the largest science project in the history of science.
    i' m sure that many of the claims that were made were sincere. That hadron collider
    would answer how nothing was the cause that caused nothing to then become everything,
    as well as creating the four fundamental forces ( two he mentioned) with each of these mathematically impossible.
    harry deserves a pat on the back for his truthful presentation. Any person with an honest interest can read the articles in many of the scientific journals to the same effect, but with some optimism, researchers are looking at new theories.
    sure we might have to throw out most of the theories that were conceived thru millions of hours of research over the last 100 years, the same ones that were argued more as fact then a thesis. Not to worry, many physicists and other scientists try not mention these
    constants and laws that govern the universe that totally fail so many of their theories

    @UselessPpp7 years ago I once ingested large quantities of lsd and it gave me a firsthand perspective of infinity in a sense of a smaller infinity within a larger one, which i' m aware most of this makes no sense whatsoever to an inexperienced perspective, but i' m getting better at explaining what i already understand daily.
    what this physicist says is true, there' s a lot more universes with nothing rather then something, but the amount of universes finely tuned, as he puts it, is still infinite (hence the smaller and greater infinities)
    don' t forget we' re just animals without the information that was collected for us. I personally find myself embarrassed knowing just how fragile i could have been if my situation was any different. Let me put things in perspective; an infant child has no information in their brains other then what they recieved through their dna. That means a lot of things, but first and foremost, it means no words. Don' t get me wrong, you' d still think, but selfawareness and progress in the improvement of your thinking capabilities would be vastly reduced, for using information would be greatly limited. It still is, but its more limited by words then anything else. Why do you think physicists use math rather than words when tackling the unknown? I personally don' t use math, psychedelics taught me how to think without words or math, but by using mere patterns (for a lack of better words) not strictly visual or auditive imaginations, so to speak, but more. I have yet to find a way to explain myself properly on this one.
    every decision you ever made was an illusion of sorts. From the tinyest ones, such as looking left while waiting for your coffee at starbucks, turning your head away from the wind while walking home, scratching that itch on your knee, trimming your toenails or finishing your meal even tho you' re full. Even the big ones, such as picking careers or marriage or whatever your mind can think of. All those decisions are what you see as control. You define yourself based on them. Well let me tell you' re wrong. You do both, or rather you do and you don' t do. When you follow every decision you ever made back to its core, its always a simple yes or no. Both paths happen, but subjectively, you only choose one. Thats as far as control goes, but belive me that eventually you' ll follow the other one aswell.
    i am a prisoner of my own mind, altho that' s just how i' m percieving it at the moment. To be honest i have no idea why i' m writing this down, it' s not my usual drift. I tend to keep my info for myself. I guess i' ve been given so much i' m starting to see the beauty in it. Not talking material things obv. Someone out there probably needs this to push through their problem, or maybe not. Or both.
    forget living in the moment, if you' re keeping up with this, you' ve done enough of that as it is. Life can be like a chess game. True control lies in knowing your next few moves and branching them out. By understanding you can tailor your own decisions to get you to where you want to be. Rather than a passenger you can be the driver.
    -
    no two things can occupy the same space at the same time (it goes something like that) wrap your mind around that. Who' s to say you' re not it. Altho thats farfetched, considering i don' t think of myself the same i was a year ago. But there' s levels (or layers) to that. I' m talking about the core, no information, no ties. Just perspective as it is.
    it' s very difficult putting all of this into words, especially considering english isn' t even my first language.
    thats as much as i feel like sharing today, for all this takes away from my humanity and i have to keep the bullshit going in order to survive by the path of least resistance in my surroundings (but not for long) no amount of knowledge will tear you out of the perspective you' re in, only death will, briefly. This paragraph was actually 4 paragraphs above but i find it more fitting on the bottom)
    the easy way may be easy, but the difficult one builds character

    @ticiamusic8 years ago The question of why there is something rather than nothing has a simple answer. If there was everor non existence, then there would never be existence of anything, because you can' t get 1 from 0. Since things exist, they must have always existed, so existence of time and space is infinite. Trying to understand fixed mathematical equations is futile when you have infinite numbers. There is nothing finely tuned about the universe, it simply exists and is infinite, so trying to use numbers to quantify the existence of dark energy or anything else is pointless. It will never make sense because space-time is not a constant fixed value. Infinity renders numbers irrelevant, as the only number that exists is 1. 0 doesn' t exist. ...Expand 4
