the Sun's mass is bigger, so it's force has a greater effect for a reason that I can't put into logical words at the moment

F= G * ( (M * m)/ d²)

 

G=Newton's Constant = 6.67 * 10 ^-11 N * m² * kg^-2

Forces is proportional to mass but inversely proportional to the distance(squared)

and it is now Heart's bedtime but I may continue this lesson when I wake up tomorrow :P

the sun weighs more, like a lot more, its absolutley massive and even though it mainly consists of Hydrogen and Helium, those gasses are at high pressures from the heat and gravity

the more mass you have, the greater the gravity that you exert, e.g. the moon weighs less than the earth and so has less gravity, jupiter (or the sun!) is much more massive (as in the mass is greater) and so has a greater gravity because of that

also when I say weighs I do actually mean masses (but that just sounds weird)

you see mass is a measure of the weight of the particles making up a substance (now ain't that a textbook answer), and is measured in kilograms. Weight on the other hand is mass multiplied by the force of gravity (which is measured as acceleration), mass is measured in Newtons (I wonder why?).

this therefore means that wherever you are in the universe, whether on earth, Jupiter, or Betelgeuse your mass is constant. Your weight will change depending on the gravity you experience at these locations

Time though is a very different element

You see, part of what Einsteins theory of relativity states is that when you are approaching the speed of light time will pass more slowly

therefore the greater your speed, the slower time passes

as a thought excersize imagine a set of twins, born at exactly the same time

one goes one a ten year journey at the speed of light (or as close to it that you can get), the other stays on earth

after ten years when the twins meet up again, the twin that met up on the journey will hardly have aged over the ten years because time passed more slowly for him (the ten year timeframe was from an earth perspective)

Meep, should beddy-bye...

Done with my exams.

Done with that insanely long PM.

Though I'll probably be writing another one in the next couple of days.

Discussions are fun.

And thought-provoking.

And really really interesting.

yeah things can get complicated

Especially when you have different perspectives and beliefs from the person you're discussing with.

beddy byes are nice
