• Is the Universe a system or made up of many system and if it is what is it's environment?

    Best answer: It is likely that our universe itself is a system which is also made up of many systems such as the solar system, the star systems and galaxies that are gravitationally bound system.

    Best answer: It is likely that our universe itself is a system which is also made up of many systems such as the solar system, the star systems and galaxies that are gravitationally bound system. Our universe itself is a system in that it is a system that is bounded by gravity and dark energy. The universe is a harsh environment. In order to existence all matter including every thing around us, must always seek an equilibrium or must be in a constant “tug of war” game that happens between gravity and dark energy. The energy needed to keep our mass intact, and not ripped apart by dark energy, is clearly demonstrated by Einstein famous formula, E = mc2.

  • Does the universe radius expanding/?

    Best answer: Radius, an imaginary line that can't expand, can only increase in length. The observable universe is about 46 billion light years in radius and if the Big Bang theory is right, it is obviously increasing with time.

  • The Edge of the universe?

    Best answer: The universe is like the skin of a balloon - so thin that it could be just 2 dimensional sheet or a wall itself if you will. As a shape of a balloon is must then be an enclosed sphere without edge yet boundless. Meaning that you can go in a straight line and end up where you started. But of course you can't go around the universe,... show more
    Best answer: The universe is like the skin of a balloon - so thin that it could be just 2 dimensional sheet or a wall itself if you will. As a shape of a balloon is must then be an enclosed sphere without edge yet boundless. Meaning that you can go in a straight line and end up where you started. But of course you can't go around the universe, it's too big and is expanding. Take note that the local universe (the observable universe) may appear flat because it could be just a small patch on a very large balloon. Remember also that matter in the local universe creates itself a 3 dimensional fabric of space-time out of its 2d sphere. The totality of the observable universe is nothing but the fabric or objects made out of the fabric of space-time - there is no edge or wall. And yes, there is a general conscientious among scientist that the universe may stop expanding. By then its ultimate fate may be "heat death" or it'll end in a "big freeze".

  • Was the curvature of space / universe different in the past?

    Best answer: The geometry of the universe is tied intimately to the amount of mass (and thus to the total strength of gravitation) in the Universe.

    Best answer: The geometry of the universe is tied intimately to the amount of mass (and thus to the total strength of gravitation) in the Universe. The current theoretical theory (based on the mass of the known universe) is that the Universe is flat, but this is not yet confirmed, because the universe could be much bigger and that they have likely not detected all matter in the Universe. So there is a chance that the universe/space has positive curvature (closed universe). If that is so, there is no reason to say that the curvature of space differed in the past. Think, for example, of standing on a basketball. It would be obvious that you are standing on a (2-dimensional) curved surface. Now imagine expanding the basketball to the size of the Earth. As you stand on it now, it will appear to be flat (even though it is actually curved if you could see it from large enough distance). The same idea extended to 4-dimensional spacetime accounts for the present flatness (lack of curvature) in the spacetime of the universe out to the greatest distances that we can see, just as the Earth looks approximately flat out to our horizon. The tremendous expansion greatly dilutes any initial curvature. I mean, the universe now is very big, so big that it appears flat even though it is still a curve, like when it was as big as a basket ball.

    Best answer: Dark energy is a hypothetical form of energy that permeates all of space and tends to accelerate the expansion of the universe. Dark matter is a type of matter (simply be matter that is not reactant to light) hypothesized to account for a large part of the mass that appears to be missing from the universe. Cannot be seen directly with telescopes, it neither emits nor absorbs light or other electromagnetic radiation at any significant level. Its existence and properties are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe.

    Best answer: The core ideas of the Big Bang is the expansion, derived from observations. Meaning that the distance between galaxies increases today, in the past galaxies were closer together or even at a point of singularity where it must have started with a definite beginning.

Meaning that the distance between galaxies increases today, in the past galaxies were closer together or even at a point of singularity where it must have started with a definite beginning. No one is sure of how the universe will end though there is consensus among scientist that the end of the universe is inevitable. One of the theory of the ultimate fate is the Big Freeze, a scenario under which continued expansion results in a universe that asymptotically approaches absolute zero temperature where everything disappear.

    Best answer: Hubble's law is the name for the observation in physical cosmology that: 1. Objects observed in deep space are found to have a Doppler shift interpretable as relative velocity away from the Earth; and 2. that this Doppler-shift-measured velocity, of various galaxies receding from the Earth, is interpreted as a direct, physical observation of the expansion of the spatial volume of the observable universe. If the universe is observed to be expanding, all the objects must have been on top of each other at one point in the past. The expansion from that point of singularity is where the Big Bang began. With out Hubble's law the big bang theory could not have existed even though the two does not have any direct link between them.
