since space is curved is a object in orbit actually traveling in a straight line.?

it depends on who its relative to.

You say that as if it is a fact....there is only actual proof of minor curvature, and that does have to do with gravitational forces pulling. You CAN travel in a straight line, imo....the curvature would never be noticed by us, as the Universe is so vast and expanding at such a high rate that we would never reach the edge of the universe which IS actually curved.

The key word is "orbit". If something is orbiting, it's in an elliptical path (usually), and hence, not in a straight line.

Time is in the curve. yes things are straight as you know them. try looking at the string theory.

The curvature of space is observable only on very, very large scales, i.e. billions of light years, comparable to the size of the observable universe itself. On the scale of Earth, space looks "flat", which is to say that it obeys Euclidean geometry. (Meaning that he angles of a triangle sum to 180 degrees.)

So an orbiting satellite is indeed following a curved path, as your intuition would suggest... not a straight one.

In the vicinity of a strong gravitational field, the curvature of space can also be strong enough to be noticed. For example, when a light ray passes close to the sun, it gets bent. In that case, the "straight" path is indeed slightly curved.

What a cool thought!

Now according to Einstein's Theory of General Relativity, gravity is the curvature of space that results from a massive object. Think of a sheet of rubber with heavy marbles placed on it. The rubber around the marbles will be curved and smaller marbles placed nearby will roll toward the heavier ones. This is analogous to the way massive objects warp space. This warping is called gravity. From the marble's perspective, it appears to be heading straight for the massive object while under its gravitational influence, assuming no other forces are applied creating sideways movement, while in fact, according to the theory, it is traveling in an arc, or curve.

Again, this is a theory that explains the motion of heavenly bodies under the influence of gravity.

Addendum: Possibly nothing in space can truly travel in a straight line since it would always be influenced by some gravitational pull. Something orbiting the earth, is also orbiting the Sun, which is zipping through our galaxie, and the galaxie is also spinning and traveling through the universe. Just try flying straght with all that going on!

Again, great question!

NO!

vast distances relative to an observer in a 2 dimensional plane looks straight, in a three dimensional plane, u can see the path which is curved, the fourth dimension which is time and the fifth hypothetically from an observer the space curve is obvious,most simple explanation would be an object travelling the fabric of space time....space curvature is evident

Gravity does cause space to curve, but the effect is very small for normal objects. A straight line through space is defined by the path that light follows, not planetary orbits. So, no, an object in orbit really is following a curved path.
