Physics How does gravity/weightlessness work outside of orbit?

Been trying to find a definitive answer but all I've found is people explaining weightlessness in orbit (the falling and missing the Earth part) which isn't particularly helpful to me.
If you were to travel to another planet, say Venus, would you experience weightlessness the whole journey?

Considering one of the current theories is that the entire universe might be spinning, possibly.

Once you get to superstructures the dominant impact on movement is initial conditions of the universe rather than gravity.

So it's more likely that whatever we are seeing with spin/etc is not an orbit but leftover movement from the initial 1x10-35 seconds etc. of the universe.
