  4. Tyler Anderson Yes. The speed at which we're going through our galaxy is 1.3 million miles per hour. So if you stopped going at the speed relative to our galaxy, your rate of time compared to the frame of reference in our galaxy, your reference frame would tick by a little faster compared to our rate of time inside and moving with the galaxy. 1.3 million miles per hour is about .001951 or 0.195% of the speed of light.  I'm ignoring all the other motions of the sun orbiting the galaxy and earth orbiting the sun, and earth's rotation as those speeds are not significant to the large 1.3 million miles per hour the galaxy is moving. Especially considering orbits of the sun and earth and rotation of the earth vectors are not always summing in the same direction of the vector velocity of the Milky Way. So relative to the galaxy, galaxies, your time rate of passing would be about 1.0000019012554222 times faster than time passing in the Milky Way (excluding local effects objects near heavy masses such as near stars and black holes and effects of planets even earth sized planets because proximity to mass has an effect on time dilation, closer to massive objects and the more massive the object the slower the object's rate of time compared to objects farther away or with little mass). Also you must realize, all objects in the universe are moving at various velocities and vectors (directions). And being at rest position is always relative. Even in the above example with the Milky Way. So you're rest position in respect to the galaxy could still be motion relative to some other galaxy or object in the universe and is only at rest relative to the Milky Way. Relativity is relative to other moving objects, and those objects in the universe does not have a particular direction and velocity to be at a universal rest position in relationship toward. Hence the Relativity is named with the word relativity. What you're asking is can you move slower than our current rest velocity, sure. But all you're doing is making that object have the velocity in respect to you at rest to it. There is no universal rest velocity in respect to everything else in the universe. It's all relative to the direction of the object and the direction of velocity to something else.   All motion is relative. In examples where rockets are used and earth is then considered object at rest, is largely because the rocket or spaceship is the one expending energy for acceleration and it's velocity is faster relative to our motion remaining on the earth. Same when trains are used, you're just sitting in one location relative to a moving train which has a faster velocity in respect to you sitting at the station. It doesn't imply that earth has some universal proper rate of time. http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/tdil.html http://astrosociety.org/edu/publications/tnl/71/howfast.html
