the effect of gravity due to an object only ends at the center of mass of the object...like gravity due to the earth...if you were to travel to the earth's center then you wouldn't feel any gravity due to the earth (however you would feel gravity due to other objects...even other planets, it is just a really small effect)
a deeper explanation for not feeling gravity from the earth is because of all the individual particles causing the effect of gravity on you...since the earth is spherical...the effects of gravity due to all the individual particles are canceling each other out...thus...no net effect of gravity from the earth acting on you

Hhmm. It's easy to look out. Not many people look in.
You are talking about the "effects" of gravity. ie. a body of mass "drawn" to another body of mass.
Yes a distance infinitley far away would technically be free from a gravitational pull, but where is infinitely far away?
On the other hand, have you thought about the centre of mass?
Here the "effects" of gravity are equal in all directions and the sum of all is zero.
Talking about the centre of the earth, galaxy, universe, what ever. Go to the centre and the "effects" are zero.
Yeah, yeah, I can hear you say, how do you get to the centre of the planet etc. argue the "exact" centre and how to find it. Whatever, but theoretically it exists and at least exists "more" than "infinitely far".
Good luck

They never do. The effects rapidly reduce with the distance you are from the earth, but the effects of earth's gravity would pull you in (assuming no other planets existed) if you were infinitely far away...

Gravity is an ever-present phenomenon if you really think about it...I mean we experience gravity here on Earth in a relatively small way: it keeps us tethered to the ground. But the moon also experiences gravitational pull from the Earth, in a large way...it orbits around the Earth. This continues when you think about the Earth and all the other planets in our solar system experiencing the gravitational pull from our sun. The list goes on and on...think about black holes as well...trippy business!

the effects of gravity never end, but gravity would get weaker as you got further away from any neighbouring planets or solar systems

All mass exert some form of gravity, so it never ends! Unless your are in a place with no mass.

As long as there is mass the gravitational pull never ends. In space we experience negligible amount of gravity.

Good question, assuming you're referring to Earth's gravity, I would say the end of the exosphere, but I'm not sure.

Where you start feeling weightlessness. and also at the extreme cntre of the core of the earth
