Are Space And Time One Continuum?

what do you think?

Space, time, the theory of relativity and the 4th dimension likely all intertwine.  These concepts are taken mostly to be fact except when we reach quantum mechanics and things get even more interesting.  Here is a brief refresher on Einstien’s work in this area and a video discussing the concept of space and time as one continuum.

“Einstein’s Dream,” introduces string theory and shows how modern physics—composed of two theories that are ferociously incompatible—reached its schizophrenic impasse: One theory, general relativity, successfully describes big things like stars and galaxies, while another, quantum mechanics, is equally successful at explaining small things like atoms and subatomic particles.

Einstein came up empty-handed, and the conflict between general relativity and quantum mechanics has stymied all who’ve followed.

What makes things more interesting is quantum physics and the famous double slit experiment.  That is the one where a photon changes direction when being observed.  How do they all tie together?

Let’s find out more in this fascinating video on page 2

    At this point they would appear to be inextricably linked. But who knows what the future will bring… If we don’t wipe ourselves out and live long enough for science to unravel the mysteries of the universe.

    Wait, isn’t time the 4th dimension or are we saying “space-time” is only one dimension not length, width and depth being 1,2 and 3 dimensions and time the 4th?

  3. Sam Joyce said:

    Basically saying time is a dimension like, up &down , right & left, forward & back, future & past. Possible directions one can move that adds depth to space.

  4. Sam Joyce said:

    Yes, space time is , infinite , static, relative. The quantum behaves like the universe , just under a different scale of spacetime, as the universe behaves like the quantum just over a different spacetime scale. The cosmos is infinite and we are all at the center radiating outward. Maybe lol

    “Space/time” is pure fiction, with no grounds in actual science, and no evidence to back up the idea. Got something negative to say? Do it with actual facts, and not speculation.

  6. Sam Joyce said:

    I agree with that, I think the curve that brings it back around we perceive as the cosmic horizon. However the nature of infinity I feel would make that complete cycle just one unit of spacetime out of an infinite static cosmos . Or from our limited perception within one of these sparks, it would appear to be absolute. Maybe!

    I fail to see anything connecting gravity “waves” and so called “space time”. Space is immutable. Gravity has no effect on space, only on the stuff within it.

  8. Jason Good said:

    Bigger the mass, the more gravity there is. Bigger objects distort spacetime more than smaller objects. Another reason light doesn’t escape black holes.

  9. James Burns said:

    No, it doesn’t. It may add to a perception of proof, but does not in itself prove it. Space is supposed to be endless, yet they propose a curve to it.

  10. James Burns said:

    The size of an object has little bearing on the strength of its gravity, rather it’s mass. ” black holes” do not have to be massive, yet have an incredible force of gravity. The fact that light can’t escape a singularity is not proof of space/time, it only proves that a photon actually has mass.

  11. Jason Good said:

    The reason light doesnt escape black holes is not actually caused by gravity. Light seeks the shortest path and inside inside event horizon the shortest path of light doesnt leave the event horizon therefore light doesnt escape

  12. James Burns said:

    1. An objects volume is not indicative of its mass. A hot air balloon is huge, yet has very little density. 2. It is easy to say anything one wants to to support his or her hypothesis on an object we cannot directly observe. The link you shared was thought provoking, but there is still much to be gleaned.

    It was undeniable proof and won him the Nobel prize in physics. Planets at hill so your point is invalid. Jupiter is bigger than earth thus has not gravitional pull. Earth is bigger than mercury and has more gravity. Sun is the biggest object in out solar system and contains the most gravity

  14. James Burns said:

    These celestial objects also contain much more mass than the earth. Why are you taking my opinions and ideas personally? Size is not indicative of gravitational force. That is well established fact.

  15. James Burns said:

    Also, the Nobel prize holds no meaning to me, check into its history. You only have to go back eight years to find fault.

  16. Jason Good said:

    His experiment was successfully done twice. You could see stars behind our sun proving light bent ars our star and einstein calculated the movement to 6 decimal places and was dead on.

  17. James Burns said:

    Ok, I can’t possibly make his more simple. A white dwarf star can be the size of our own Earth. Do you think they have an equally strong gravitational pull? An equal volume of Jupiter to that of the Earth would float on our ocean. A hot air balloon has a large volume ( it takes up lots of space) yet has very low mass. Jupiter is akin to that balloon, but it’s sheer amount of matter creates its large gravitational pull. If Jupiter were a rocky planet like our Earth, yet still took up the same space, it’s gravity would be even greater.
