What do we know about the Sun and the Earth? What most people know is that we, on the Earth, orbit the Sun all willy nilly. What most DON’T know (and I will keep it simple because I am lazy) is why.

Now in this diagram we can see a net. Try to see this as the map of time and space. Now we know the rumor that is the planet was 10 feet closer to the sun we would fry, or that if we were 10 feet further away we would freeze? Well that is false, in fact distance from the sun varies during the year. But what is true is that if the Sun weighed more we would be much closer then we already are.

How is this possible? Remember the net? That one right there in the image? Well see it like this, the heavier the object the greater the dip. Not getting it? The more mass it has the greater the gravitational force of the object. So we are orbiting the Sun due to it’s great mass and gravity.

So if the Sun was larger in mass, it would have a greater pull in gravity and in theory, would pull us further to the Sun. How much further? That really depends on the mass of the Sun.

Now This dip in the eyes of relativity can effect time as well. Imagine you are living on the surface of a neutron star (which is very, very dense and massive) then time would tick over much more slowly than for the people outside, living on a normal planet. Now time moves the same no matter where you are, but if you lived on a neutron star(not possible btw) and came to earth, you would think that time was moving much, much faster than it should. Same could be said about an earthling who went to live on the neutron star, they would think time is passing far to slow.

So if you catch my drift, then you now understand that mass and gravity can affect us in many more ways than you might think.
