    Since the days of Ancient Greece, philosophers and scientists have been wondering: What is space? Is the absence of things
 a thing? These questions continued to fascinate physicists in the modern era, leading Isaac Newton, Ernst Mach, and Albert Einstein to wonder about the true nature of the fabric of the cosmos. The search for an answer led them to some of the greatest theories in physics. This week, we ask if space and time are really real, and how they come together to make “spacetime”!

      As a physicist this is the answer to so many simple questions.... Almost like "It depends...". The problem is: The universe isn't "simple". So how should there be simple answers - especially to simple questions? "Is the Earth flat?" - "No, but yes, maybe, it depends - if you are moving with the speed of light, basically everything is flat, but if you don't, Earth behaves like it isn't, but maybe we are wrong about the behavior of things, so maybe it is, but .if you view it from the point of view of a four dimensional being, you can wrap the earth into flat shapes, but if you are a being of higher dimensions you most probably don't have any idea of what 'flat' is., but...".

      We have tools to help humans try and grasp what is happening. Like maths for blackhole gravity. We humans have a need to make something this or that. Yet light is a wave and a particle point. It's not a wave OR a particle. We don't have the right definitions at this time to describe many things that math can prove. That is all. Our time of understanding/definitions are going to update as we gain a sensibility of it all. Humans couldn't fathom germs, now we do.

      @@MrHeroicDemon the fact that we can't understand what maths proves it's a problem, but what does it mean? It means that there is a real shift between reality and the object of science itself. Reality as we experience it normally is not just an illusion, but it's the realm in which we can't not live. We don't live in the realm where things are and aren't at the same time - at the same time, to make sense of our reality, we must construct something that isn't part of normal reality. One of those things is time. We don't, and won't ever experience time for what it is according to scientific theory. But scientific time isn't TEMPORAL at all. So, while "time" may be a physical notion, the character of temporality is the foundamental way of human experience of reality.

    As far as I know, Einstein was a fierce defender of Mach‘s principle. He did not believe that spacetime was a thing. Also acceleration must be relative to SOME reference frame. The bucket water would NOT bend in an empty universe. Considering the Lense-Thirring effect, there even seems to be empirical evidence for this apparently merely philosophical stance.

      Hey guys, Michael, Vsauce here. As we all know, the word space derives from the Latin word 'spaceibus' which, back then meant big. They would often use it to describe house size. Anyway, space. What is it? Space is where there is nothing. Like a vacuum. Vacuum is a cool word because it is the only word to have a double U but not a W. As I was saying, space is a vacuum (nothing), a place where there are no atoms. For example, if I was to hold out this empty bottle *shows bottle* it may look empty, but there is actually matter in it. Atoms, particles if you will. Oxygen with a combination of other gases and even water. In conclusion, the answer is... No.

    • @swinde

      space isn't really a thing, just a part of a thing. space is 3 dimensions but we are 4 dimensional and the fourth dimension is time.
      my theory is that the expansion of the universe (which is constantly accelerating) is time and it explains why time only goes in one direction because the universe is only expanding not contracting. Matter warps space time and this warping effect causes gravity however the warping effect also causes time dilation due to time being a quantity of space time. this also explains why the speed of light is constant as photons are massless and therefore do not warp space-time and can travel at the maximum speed allowed by space ( shown by that nifty graph at the end other the video). I probably just came to the same conclusions as many other people but this video really cleared it up for me. Thanks itsoktobesmart !

    Can anyone please clarify this?
    I've heard that the universe started out from a point infinitely small; hot & dense.
    My question is, if the starting point of the universe was just a hot & dense state...then what was available to compare its temperature & density too?
    Hot compared to what?
    Was there a temperature outside of this hot dense state?
    Dense compared to what?
    Was this hot & dense state contained inside of something else with less density?
    How can something be described as hot & dense, when there is not yet anything else to compare its temperature & density to??
    -Thank You in advance for your clarification.

    • @roner61

      You need to check temperature definition:
      Cold and hot are relative to atoms movment.
      The coldest: atoms with no movment.(or minnimun possible)
      The hottest: atoms moving at the maximun velocity possible.

      Idk the correct answer to this question, but in ny opinion, this is still considered a very good question! After all, I was taught that no matter, person, place, thing, or any event cannot exist without spacetime. There would have to be the 3 spatial coordinates of x, y, & z for there to be a place for any existance, plus the w coordinate to represent time and tell us when it existed. So without spacetime, there definitely isn't a time nor a place for any matter..
      But what if that concept is also, somehow, actually reciprocated?.. as to imply an inverted causality that would nullify any existance of a spacetime without any kind of matter or substance to validate any space or time (the duality of reality shows its face almost anywhere you look) #thingsthatmakeyagohmmmmm

    • @roblaquiere8220
      @roblaquiere8220 Pƙed 7 lety +5

      To answer your questions we need to understand the differences between space-like and time-like motion. The four ships in this video's example display these alone and together:
      Diagonal Ship: Both space-like and time-like motion, this ship is not accelerating. The velocity of the space-like motion is X m/s, something we understand easily using basic physics. The time-like motion has a speed that is curiously measured in seconds per meter, in this case it would be traveling through time at a rate of... 1/X s/m. Yes, you travel a number of seconds through time per meter of space traversed. Remember Einstein's clocks measure time by measuring a photon in motion through space, space is measured in meters; seconds per meter is literally the unit of time-like motion.
      Perpendicular Ship: Only time-like motion, this ship has zero velocity and is not accelerating (not possible for reasons, but I'll continue). The time-like motion has a speed of ∞/0 s/m because you would travel infinite seconds for each 0 meters traveled... therefore ships truly at rest have an undefined speed in time-like motion.
      Parallel Ship: Only space-like motion, this ship has velocity of exactly C and in not accelerating (and has no mass, somehow). The time-like motion of this third ship is 0/∞ s/m because you would travel zero seconds for each infinite meters traveled... therefore ships traveling at C also have an undefined speed in time-like motion, but it is a different undefined.
      Curved Ship: Both types of motion, and is accelerating. Nothing different than the first ship to be honest.
      Einstein used a distance metric that included time called the Spacetime Interval, this metric measured the distance between two points, like the endpoints of a ship's path, in such a way that all observers would agree on the interval regardless of their frame of reference while observing some event like a ship path. Spacetime intervals that do not have one component of the interval, the space or time component, are special cases that only work in particular cases. I could go on about it, but I have said enough for now.

    • @feynstein1004
      @feynstein1004 Pƙed 7 lety

      +Felix Vogel You can know that you're moving because it's impossible to stay still in spacetime. In fact, everything is moving through spacetime at the same velocity (the velocity of light). Now how much of this velocity gets transferred to the space or time directions depends on the reference and hence is relative. However, the actual "speed" of everything is always the same. You should take a course in special relativity. It's really interesting. And fascinating as well.

    • @roblaquiere8220
      @roblaquiere8220 Pƙed 7 lety +1

      This is not correct. Not everything is moving through spacetime at the same velocity. Remember, velocity is a measurement of speed and direction... surely not everything in spacetime is moving in the same direction. The absolute value of velocity, on the other hand, is the same for the types of matter and energy we have discovered. I don't want to rule out the possibility of discovering matter or energy that does not obey these rules however (I think of Tachyons from Star Trek).
      In fact, some hypotheses imply that exotic matter like anti-hydrogen is in fact normal hydrogen moving backwards in time... This means that particle anti-particle annihilation is just two normal hydrogen smashing into each other in the time dimension! One from the future and one from the past! The reason the charges are switched is because we are seeing the anti-particle moving in reverse through time, and thus the EM waves produced by the anti-matter is flipped. QED predicted anti-matter's existence because of these ideas, and we have indeed synthesized anti-hydrogen.

      I think you got that a bit wrong. Mass is not changing to energy and back again. Mass IS energy; it's energy that is trapped from traveling at the speed of light. Thus it is energy that experiences time (since, as described in this video, if something does not move at the speed of light then it travels through time instead)

      Chaitanya Singh It does not have mass since its made up of "virtual particles" whitout mass. If they however had mass that would break the thermodynamic law about conservation of energy.
      The virtual particles have to exist in the first place to satisfy Heisenbergs uncertanty principle about energy and time. The more you know about the energy of a particle (or in this case, vacuum) the less you can know about the time it had that energy and vice verca. Because a classical vacuum would have no energy in it there would be an infinite uncertanty about the time the system had that energy, which is simply not plausible, therefore viritual particles were theorized and later proved to be right by the casmir effect.
      If i remember correctly the energy required to make those viritual particles are borrowed from space itself, creating negative matter (not to me confused with dark matter or anti matter) for a very short amount of time.

      It is not a theory, it can't predict nothing. Just philosophy. You can write whatever you want, but to predict events is far more complex.

      JLC You're right. Kant stated a philosphical thing. Physicists don't sit back, think about those things, write down their thoughts and call it a theory. a physics theory needs to be proven with math. talking about these theories, like it is done in this video, is just explaining what the math means for real life

    As usual, awesome video! Pretty interesting how Newton's concept was on the right track he just didn't have all the accumulated knowledge Einstein had access to maybe?

      Symphonic power metal makes absolute sense for introducing Dr. Einstein.

    the problem with the analogy of the bucket is, that at each point during the spin, you're actually on a linear trajectory moving outward relative to the bucket.
