Traveling to other galaxies will be impossible, once the nearest galaxies to us are receding faster than the speed of light. Not only can we not travel to them, their light will eventually stop reaching us (and ours them) so our galaxy will appear as an isolated island in the eternal blackness of extragalactic space.

However, in a more local sense, because the gravitational force overcomes the expansive motive force, the galaxy will stay more or less as a cohesive unit. Same with solar systems, planets, atoms, etc. So, even if the universe continues to expand at an accelerating rate, our galaxy will still remain open to us. And it's a big place. It should keep us busy for a while.

Ras is a protein involved in cell cycle control. Look at the image...a very large number of arrows (pathways) point to that protein. It's highly important for cell cycle cessation, cell-cell contact, growth signalling, etc.

A single point mutation in Ras - which amino acid is what differentiates H-Ras, K-Ras, etc - is often sufficient to throw the whole cell out of balance and lead to cancer.

This is the case in very few other pathways. Redundancies and checks and balances are commonplace. To see such a weak link in such a critical intersection between pathways is, in my eyes, either evidence of no designer or an incompetent one.

Vibrations and rotations are on the order of 10^-14 and 10^-11 seconds in period. The highest frequency (lowest period vibration) a human ear can hear is about 20,000 sec^-1, 5*10^-5 sec period. Significant difference in frequency. Although that's certainly not the defining difference between the two modes, that dichotomy can be drawn.

It moves to a different point in the universe. Unless it can move freely in the dimension in which the universe is curved, it will not leave the universe because there is no end of the universe in 3D for it to reach or cross. Hence, finite and unbounded.

Consider the same situation on a 2d universe curved in the third dimension: a globe universe. Your globe is expanding at a given rate. You posit a particle moving faster than the rate of expansion. Disregarding the fact that comparing movement (dx/dt) to expansion (in this globe case, dV/dt) is senseless, no matter how fast your particle moves it will never escape the universe, because it cannot move in the third dimension. It is confined to the surface of the globe, and it will stay there.

How much money would it take for a private sector company like Spacex or virgin galactic to put a long term habitat in orbit?

Why aren't these private sector companies (read: for profit) mining asteroids? Spacex announced a desire to mine lunar water a while back, but no one ever says anything about mining metallic NEO's.

2550's.

Live forever or die trying.
