the god Einstein has a flaw, or does he? =|

[King Alboin]

when traveling faster than the speed of light is it dark since the light is slower than you and has not yet gotten to the destination will you ever be able to see again if you continue moving faster than the speed of light

well, let's think on that for a sec. k ... say you are at C [light speed], flip the light switch and BOOM!, darkness. However, the light generated is still energy generated, yes? soooo ... perhaps then you could see dark matter, seeing how that the light produced is dark light, stemming from a dark energy source, therefore, ipso facto, dark matter presumably would come into view.

I do find it incredible that some of the stars you see in the night sky no longer exist and its just there light is still reaching us because they are/were so far away.

Think about that long enough and you go mental.

Trust me, if you drink enough coldbeer, it is impossible to go mental this side of quantuum diverginary physics. Scientist have already seen the echoes of the big bang, a long gone spectre of ancient past, drifting headlessly into a vague future of obscurity. *hic* 0.o

but, that is why I ask about the timeline. Time, space, gravity are inexplicably connected. Inextricably tied to each other. Time can no more escape gravity, as gravity can no more escape space. If said lego astronaut is part of the same time, space, gravity scene as Serena and Gorindia, then would not he experience the same timeline, they are experiencing? Linear motion of all three make up the fabric of existance. How would going the speed of light change that? how could one exist separately within a normal space, gravity, time arena, being itself a separate space, time, gravity arena? would not it all be the same?

Okay....I am trying to get my head around this I really am......let me ask you this.

Lets say you have a space car with a limitless fuel tank. Now there is no friction, gravity or wind resistance in space...if you put your foot to the floor would you surely not keep accelerating until you passed the speed of light?

[King Alboin]

Einstein says, no, nuh uh, aint happening, caneezy noteezy beneezy doneezy.

However, no one has seen nor measured dark matter, let alone dark energy, so I say, sure, why not. acceleration can be infinite till you hit the universe barrier, or something like it.

yet I must state, that Einstein says, that if one was to hit the universe barrier, they would eventually return to where they started, cuz he says the universe is curved. so your light speed vehicle could scrape and spark up the universal guardrails a bit, turning so sharp, highbanking the Universe's curvature but you would be on track for a most awesome return, that no one could see cuz you are in actuallity faster than one can see. just saying

but what do I know, I am just a drunk with an empty beer can ..... scratch that ... I am just a drunk with a now replenished full coldbeer can.

there is a reason Rodenberry mentions Warp Factor 9. right?

but what Einstein says, is that when you reach the speed of light barrier, and go faster than ... you>C, then you will start to travel backwards in time, till you go past twice the speed of light, then you go back to going back in a foward timeline ... thing.

make any sense? and oh, lookie there^ another flaw.

[earlofspark]

Yes but the whole time travel thing is theoretical anyway...what about the space probes currently out there...are they still not accelerating?

Oh and rep on its way when I have some.

Your posts are like mini episodes of TBBT.

[King Alboin]

about the probes?

I would think that no, they are not accelerating ad infinituum and/or will eventually slow down, due to semi-fact that their inertia is more on the line of kinetic energy. Which as you know has an apex, then slows down. For there is still sub-substance in space to affect a slow down.

And about time. Time is linear. Its always on one line going that away ------------->

whatever happens to everything else, i.e space, gravity, .. happens on a that timeline.

[earlofspark]

But does kinetic energy have an apex in space? Barring meteors etc....

[King Alboin]

yes, kinetic energy has an apex, even in a pure vacuum.

if you look at space, it is really cluttered with all kinds of gritty little particles, just aching to become planets. Super Novas put out enough trash when they expode to fill half a quarter of a galaxy with debri of rare elements.

Even if you take the sub-substance sub-particles out of the equation, you still have to deal with gravity, and the space in which it exists.

One might even consider dark gravity, and and and dark space, oooh oooh and dark time. those will stop a probe, dead in it's tracks, I'm here to tell ya.

[earlofspark]

Damn it Albion you thwart me at every turn!

One last question before signing off for the night to watch Rocky.....

Can you watch Back to the Future without screaming at the TV because of the inaccuracies?

#Thanks for the craic

[King Alboin]

No, no I can not. the inaccuracies are all LIES ALL LIES i TELL YOU!!

laters earl.

There's a problem involving mass, because the faster you go the greater your mass becomes and the more energy would be required to generate a faster momentum, so that it becomes theoretically impossible for anything with mass to reach the speed of light. That's according to Albert, who saw light as having no mass and made of waves but in more recent times, physicists are finding that light is both waves and particles and particles have mass, so they shouldn't be able to travel at the speed of light but they are light (particles) so they do. (get yur head around that one!) (Gravity is still present in space. It may be a fairly weak force but when it comes to astral bodies such as stars or black holes the force of gravity is quite massive and can be quite difficult to overcome. Entire galaxies form spirals, that's gravity in action. There may be some places in deep space where there is no gravitational effect but even those spaces would be shaped by the gravitational forces around them.)

......................................

See, Einstein did this thing where he talked about looking at a clock and from a stationary position you see time pass on the clock face because you see the hands moving around the dial but if you accelerate up to light speed but still keep watching the clock face, you are now travelling away from the clock at the same speed as the light from the clock face takes to reach you, so in effect the clock seems to freeze and time stops. So time becomes frozen at the point that you left, from your perspective. But the clock on your ftl (faster than light) ship is still running and inside your ship is (what I would call) a relativity bubble , so your ship's clock appears to be working normally from your perspective. As light has a measurable speed - 299,792,458 meters/second - we can work out how far you would travel in 3 years if you are going at light speed but that is from the perspective of the point of origin, not the perspective of the traveller. The traveller is now on a different time stream than the (relatively) stationary observer, so very little time may pass for them inside their ftl relativity bubble. Of course, the first problem is surviving being blasted up to light speed and then surviving as a being of nearly infinite mass. Then there is the massive decelleration and reversed acceleration on the return volley. It gives me a headache just thinking about it.

This thing about banging up against the barriers of the universe (or crashing through and out), it's not going to happen. Space is curved. But space is big, really, really big. So you can't percieve the curve, so you think you are flying at high speed in a straight line but it's like driving a car/boat around the world; you think you are driving on a (relatively) flat surface in a straight line but eventually you will end up back where you started. But space is really big and the world is tiny in comparison, so to travel the whole of time/space and end up back where you started could take a really long time, even at speeds faster than light. Us puny humans shouldn't even be thinking about that sort of stuff really because we keep trying to reduce things down to a scale we can understand and that doesn't really work out well. You just have to accept that space is really, really big.
