what limits something to a max or min eg. the speed of light and 0kelvin?

Answer 1

Maximum gravity can be exhibited by a black hole. None is greater in gravity aspect than a black hole. In one word, its gravity is infinite. Size of Universe is infinity and it is the limit to size because nothing is greater than Universe in size.
Thus a factor that we cannot measure than that limit states that it is a limit to that. When we take speed of light, according to Newton, the mass of object should become zero when it is travelling with speed of light. It is practically impossible because if an object's mass is zero, it doesn't exist in real life. So it means that no object can travel with a velocity which is greater than velocity of light.
Similarly, Absolute zero(0 kelvin or -273.15 degrees centigrade) is the lowest possible temperature, occurring when no heat energy remains in a substance. Absolute zero is the point at which molecules do not move (relative to the rest of the body) more than they are required to by a quantum mechanical effect called zero-point energy. It is practically not possible to achieve absolute zero because, every body emits some heat. But on February 2003, the Boomerang Nebula, with a temperature of -272.15 Celsius ; 1K, is the coldest place known outside a laboratory. The nebula is 5000 light-years from Earth and is in the constellation Centaurus. Thus scientists achieved nearest temperature to absolute zero and cannot achieve completely absolute zero.

Answer 2

Absolute zero is the point at which matter contains no "extra" energy. It is theoretically impossible to attain. So, you COULD look at temperature as not having a lower limit (no minimum) kind of like the greek puzzle about how many days will it take you to move 100 feet if the first day you move 50 feet and each day after that you move half as far. When will you reach 100 feet?
Since we think there might be negative energy, I'm not so certain 0 K is "it" anyway....
Speed of light. I'll have to answer "because" on this one. Why couldn't you travel faster? WHy isn't the speed of light instantaneous (or even faster - say arriving before it left)? Because it isn't. Not very helpful. Just the way we see it. (pun)

Answer 3

you almost had it once you stated: "anyplace you're time seems to be happening a similar fee, each and every thing else will velocity up or decelerate relative to you" which will inevitably bring about conflicting observations considering that an observer on earth would see that the practice clock slows down and an observer on the practice will see that the earth clock slows down. A contradiction? No. considering that those observers are in distinctive inertial frames there is no conflict. in the event that they have been status table sure mutually interior a similar inertial physique with those observations there would be a paradox yet that isn't the case right here. What you have completed is take the area traveled by skill of the practice as talked approximately by skill of the earth observer and the time registered on the practice's clock then blended them to artwork out an impossible velocity. we can not combine techniques from distinctive inertial frames in this way. Why? properly if we could try this then the clock on the practice would (in concept) tick at each and every a threat fee similar to each and each inertial physique you are able to word it from. Preposterous! each and each inertial physique has observers who make self sustaining observations that are in basic terms actual of their own physique. As for the 2d area; it is the area-TIME[edit] ITSELF that extra advantageous. the theory that there is extra room for the universe to strengthen in to isn't splendid. think of the textile of the universe because of the fact the exterior of a rubber balloon being inflated, this could inform you that there is not inevitably any return and forth of remember from ingredient to show because of the fact the universe expands purely the expansion of area-time[edit] itself.

Answer 4

speed of light: we don't have any sense that moves faster, so we don't have any way to detect if anything is faster, though we do have theories that it might exist.

0kelvin: heat = energy, when there's no more energy, you can't lose anymore. Just like you can't measure a negative distance. The distance is always positive, even if you decide it went in a negative direction.

Answer 5

Limits are set by a thing called 'Physical Reality'.

It's a difficult concept for some people.
