Cern to repeat light-speed experiment

The scientists are always behind reality. In the early 19th century they were saying no human could travel faster then 50 mph. And the scientists miscalculated concerning the sound barrier. How many times did they say humans and planes could not go faster then the speed of sound? And then came the space age and they were arguing that humans could not go into space because of g forces invovled. So we sent the monkeys into space first to see if they could survive. Even after they came back safely the US scientists still did not believe that humans could go into orbit. So when the Russians launch... [More]

There is nothing preventing travel faster than light speed. What becomes confusing when thinking about the issue in a thought experiment, is the medium through which one must travel. G forces do not actually apply in this scenario, as one would be travelling outside of a particular planet's gravity well. The associated and often confused term that applies here, is inertia. One could not immediately accelerate to the Speed of Light, nor could one immediately decellerate from such a speed, without the forces of inertia acting upon the body. In the absence of atmosphere, gravity, and other forms ... [More]

The speed of light would, it's commonly held, never be attained at *any* acceleration. It would be possible to come arbitrarily near the speed of light -- say, ~99%, of C after about a year of constant 1 G acceleration. Any greater G force over the long term could possibly be harmful. I'm sorry, I don't mean to be rude, but this is just nonsense. Accellerating at 1G will never ever ever ever hurt you. In face we've all been doing it for the entire duration of our lives. It's amazing to me that people forget that they are even now sitting on the surface of a planet that is moving through space.... [More]

It's amazing to me that people forget that they are even now sitting on the surface of a planet that is moving through space. We call it 1 G because it's a term that relates the force of Earth's Gravity. Kind of like we call 1 AU (Astronomical Unit) the distance between Earth and the Sun. These are Earth terms. We made them up, because it's easy for us, because we live here. We count in base 10 because we ha... [More]

I believe you'll find, if you look at my post again, that I was speaking of the possibility of long term acceleration *greater* than one G being harmful. I called it merely a possibility because we have no practical data on the effects of year-long acceleration at greater than one G, on the human body. Given what we *do* know of the effects of G forces, it seems reasonable to expect some negative effects, particularly at accelerations well above one G. I also believe you'll find that Einstein's theory of relativity states that there is no real difference between the effects of being in a gravi... [More]

There is nothing preventing travel faster than light speed. I would say there are things preventing FTL. ...one could certainly gradually approach and surpass the speed of light. The speed of light is not a 'speed limit' it is merely a constant that we use for to understand the measure of the observable universe. No, it is a speed limit in the theory of relativity. It would take infinite kinetic energy for a massive object to reach the speed of light. To surpass the speed of light the object would have to have a purely imaginary mass. However, just because our current deion of the physical uni... [More]

Are there not differnt types of photons aka light that may travel at slightly different rates of speed. I believe so. Plus zero gravity is harmfull as well as one G. Both have effects on the body and over time both harm us.

Are there not differnt types of photons aka light that may travel at slightly different rates of speed. I believe so. Not in a vacuum. In matter the electric permittivity and (sometimes) the magnetic permeability are different for different electromagnetic wavelengths, so different colours of light can have different speeds (or more reasonably, radio waves may travel slower than microwaves) In all cases, however, the vacuum speed of light is an upper bound on the speed of regular light propagation in any material. (The phase components of virtual particles can sometimes exceed the speed of lig... [More]

(The phase components of virtual particles can sometimes exceed the speed of light but this does not really involve energy propagation. Some systems exhibit negative group delay where the group velo... [More]

Correct me if I am in err in reading your posing. Wouldn't an acceleration of 1G permanent eliminate the negative effects known to exist in living in space with near 0 G forces? I would predict, in fact, that considering 2 persons in space (with 1 under permanent 1G acceleration and another with anything less than 1G forces) an accelerating person would fair measurably better in great portions physically to the more stationary person. Mark Yes, any departure from one G, either downward toward zero, or upward of one, could present a problem. Any means of generating effects like those of a gravi... [More]
