Speed and acceleration are two different things. Speed is how fast something is moving like 50 miles/hr, 100m/s etc. Acceleration is a measure of how fast something is changing speed. What you are thinking of is acceleration not speed.

Think of a drag racer(race car). It goes from rest (0 acceleration, 0 speed to something like 300 miles/hr in a few seconds. Now acceleration is related to the force experienced by the driver from Newton's law: Force=mass*acceleration. So with a race car the driver would feel a great force acting on them due to the car's velocity changing rapidly. But once they stop accelerating (their velocity is no longer changing) they won't feel a force acting on them despite having a speed of 100+mph. This is the same thing in space. When a rocket launches the astronauts feel a large force due to the rocket accelerating very quickly but once they reach orbital velocity and the engines are shut off they are still travelling very fast but are weightless. So a rocket could be moving at 99% the speed of light and you wouldn't feel any different if the engines were shut off and the rocket was "coasting."

The max acceleration (for simplicity I'll call this G-force) a human can experience differs. Fighter pilots can handle 6-7G (6*9.81m/s^2 aka 6 times the force of gravity) pretty easily with their G-suits and training and they can handle 10G for short periods of time. Without G suits and training most people would really struggle to stay conscious with 3G. At 20G your aorta will tear out of your heart and your will die in seconds. This is assuming the acceleration force is acting down while you are standing or sitting. If you are laying on your back you can handle a bit more G. So for your train example you could have one going 1000mph as long as you aren't accelerating it too quickly. People wouldn't like to pass out or die each time they get on the train.

As for your thoughts on time dilation you are thinking more like EVE's time dilation where time slows down and not relativity time dilation. With actual time dilation you wouldn't get "extra" time to save your life in your "falling house" idea. The way time dilation works is this. For the person moving at .99c they would experience 1 second just like you are now. For the observer standing still they would experience 1 second just like you are now. But the .99c person's 1 second would last "longer" than the 1 second for the observer but each person wouldn't feel any different. This is like that "twin paradox" thought experiment where one twin gets on a spaceship moving .99c and the other twin stays on earth. When the spaceship returns to earth the twin on earth is much older if not dead and the other is only slightly older. Time travel is a hard concept to grasp.

Is dark matter just a catch all for "we don't really know so this is our place holder name" like luminiferous aether once was?

Well with my post, I am going with people are not superman. I agree with your science, but can humans live your science. That is mostly what I am going with. Like you say yo u can go any speed, and humans are superman so its no big deal. I usually dont see it that way really. My questions are bit wierd since I am not doing just pure science and humans can handle any science theory real well. Mostly going with science, plus how people are right now handling the science really.

Best way I can describe it is stephen hawking. He was chasing the unifying theory and thought it could be reached. But now he sees the way things are and how humans are and has given up on that chase, and thinks we are far from it. He now just looks at different branches and tries to learn about them. Like try to see the individual better, more then the big picture always or something.

Easier thing is this I suppose, a baby cannot throw a ball, a child can throw a ball, an adult can throw a ball, even throw it far. So with velocity and stuff, a baby can handle small velocities, a child can handle some, and an adult can handle alot more velocity. Or acceleration as well.

For me as an example, I can travel at 800 mph, and not feel any pressure as you claim. But the buildings and billboards and trees will go by too fast for me to make decisions, I will panic and crash the craft I am flying.

Sorry I do have a wierd way at looking at the science theories presented here, hopefully this clears it up. It is a cool thread and it fun to read the posts.

rodyas I'm sorry man but you have a very different way of thinking and I'm having a hard time deciphering your post.

Will we ever be able to utilize the twin paradox to make instantaneous communication possible over any distance?

IE modify and read the spin of entagled particales.

there is a lot to read here and i have never heard of this particular contribution by Maxwell, so i will have to get back to you. i will edit this post with a response.

the twin paradox was proposed as an argument against special relativity, and has nothing to do with quantum entanglement. it was accepted once we had empirical evidence for time dilation.

from what i have read, there is a bit of confusion with time dilation here, so here is the gist of it. my answer to your question about entangled particles is in a previous post (on FTL communication in EVE).

time dilation arises directly from special relativity, which has two fundamental, core principles. the first is that there is no absolute or preferred reference frame in the universe, and the second is that the speed of light is the same across all reference frames. it is this second point from which all of the interesting effects arise. consider two observers, one on a train riding past another standing by the tracks. on the train there are two mirrors, one on the floor and one on the ceiling. the observers both watch a photon bounce from the floor to the ceiling and back again as the train passes. if the train has a height of h, then the person on the train sees the photon travel a distance of 2h. HOWEVER, the person outside the train sees the photon travel along two sides of a triangle of height h (the photon has both a vertical and horizontal velocity). upon comparing notes, both observers agree that the speed of the photon was c! but speed is defined as the change in distance over a difference in time. in order for light to be constant across reference frames, then distance and/or time must change in order to "compensate". because the universe doesn't seem to distinguish between space and time as far as physical law goes, BOTH change in order to keep the speed of light constant. the distance contracts along the velocity vector and time dilates. time passes slower for the person on the train.

nope! we actually have astronomical evidence for dark matter, even through we have never observed a dark matter particle interaction. we can look at the night sky and observe the movement of matter we can see, and from this movement we can create maps of the gravitational fields at play. these gravitational fields point towards quantities of matter that we cannot currently observe acting on the stars around it.

the best example for this is the rotational velocity of stars in our galaxy. for stars very distant from the galactic center, we observe velocities much higher than what are predicted by newtonian gravitation or general relativity. many theories were created and tested, including the modification of newtons laws, but the presence of unseen matter fit the observations best and BAM! enter dark matter. from what we have seen we can also estimate the properties of such matter. for example, most dark matter is probably non baryonic and cannot interact electromagnetically. because of this, we have named all possible dark matter candidates WIMPS, short for Weakly Interacting Massive Particles.

I cringe every time temperature is described as vibrations though, since when things get down to the atomic level, the describing their kinetic energy as simply vibrations is just a bit simplified....
