Artema’s Universe

Gravity, acceleration, speed and time

Gravity was “discovered” by Sir Isaac Newton. He observed that an apple goes from a position of rest on a limb, and accelerates during its fall. From that he gathered that a force must be accelerating it. He used the works of Tycho Brahe and Johannes Kepler and derived the basis for the modern formula on gravity.

Time is very interesting. It appears time is affected by motion. To explain this better I will use an example from The Elegant Universe by Brian Greene. Imagine you are traveling between two lines, one kilometer apart, and it takes 1 minute to reach the other side. Now, while still going in a straight line, start by facing left slightly, and it will take about 1 minute 5 seconds. You’ve gone from traveling in one dimension to two dimensions. There is a certain amount of energy distributed between the 4 dimensions, and when you put energy in one of the dimensions, it takes it away from the others. So as you travel in both the first and second dimensions, you’re taking energy away from the 4th dimension: time. Now imagine you’re traveling down hill slightly. The distance is still 1 kilometer as the bird flies, but driving distance will be greater as you’re still going to the left and now downhill as well. You end up taking 1 minute 20 seconds if going the same speed as before. You were traveling through all 3 dimensions this time, and it took even more energy from the 4th dimension, thus taking more time.

Incase you didn’t know, light is frozen in time. Photons are traveling at maximum speed, and all the energy that can be spread between the 4 dimensions are being put into the first 3, leaving none left for the 4th dimension. It is actually possible to do minor time travel in our solar system. It is not uncommon for a long space mission’s clock to be off a fraction of a second on its return to earth. Traveling away from the earth’s motion can literally make you lose time.

Speed and acceleration appear to be simple concepts. They are very rudimentary on earth. You go from a resting position to one in motion, and the change in speed is called acceleration. Once you stop accelerating, or changing your speed, you are at a constant, and no longer accelerating. One note on semantics that I want to point out is about deceleration, it is actually negative acceleration, decelerate is a poor term.
