Oh... and if you were traveling near the speed of light.... everything around you would appear in your forward vision. You would see almost all 360 degrees directly in front of the ship.

It would be very confusing to navigate that way.

wow

would that be a similar view to that i would get looking up from the event horizon of a black hole?

Someone unfortunate enough to be just inside the event horizon of a black hole would see the universe looking perfectly normal. Hostile - lots of really bad radiation rushing inward - but otherwise normal. From the outside. the event horizon is a bizarre interface where in-falling material seems to get "stuck," slowly disintegrating until it can no longer be seen. From the point of view of an object falling in, there is no obvious difference between being on one side or the other (until said object attempts to exit the vicinity, of course).

That's his biography, not the relevant math. Hang on, I'll look it up.

Ok. after plowing through the Wiki SR article, to the observer on the starship the distances to destinations appear to shrink, because the observer's clocks are running slow. It is as if the star in front of the ship, and the intervening space in front of the star (and the space behind the star), was all moving toward the ship at a high fraction of fthe speed of alight and was length contracted. Neat idea.

*scratches head*

where as 4 the observer space does not contract but the ship does !! lol



my theory is that it takes particals a bit longer to work out where they are in relation to everything when moving fast or in large numbers so they have to slow down a bit

For which observer?

To the external observer, the starship is length contracted. To the observer on the starship, the starship is not length contracted, because his meter stick is also length contracted in the direction of motion just enough so that when he measures the length of the starship in the direction of motion, it has not changed. The interesting things occur as he travels to the destination star in what to him is a very short time, because his clocks are running slow.

Let's do the time warp again...

I have been trying - for years now - to determine what would happen if the 'Ether' is truly a function of mass, not a change in clock speed. One of the results is that light would travel faster in inter galactic space. But how much faster, and what controls the velocity? I don't have good answers, but the fact that greater gravitational lensing is observed that is predicted (and interpreted as a dark matter effect) could also be a 'no matter' effect -- a slightly greater velocity of light.

I would tend to think that there is no limit to the speed of light with nothing to restrict it. But when time is a factor, it becomes a line.

That sounds confusing.

If a photon was going its speed in the universe unhindered, and experienced a "nothingness" it would instantly be at the "other side".

You can't therefore guage its speed.

I think gravity, and time work the same way.

That being... if you take out everything (anything) in between.. the effect is right there.

If there is nothing between the light source and the destination, the distance in null.

Without editing my previous statement, I want to say when I speak of gravity... I mean mass.

With No mass of any kind... and no electric charge, there can be no force. And therefore no space...which leads to no time.

There would be nothing to traverse.

When you say mass, do you mean energy? In GR, it's energy that causes the warping of space-time. The amount of energy in a given amount of mass can be found by using E = mc².

I'm not sure. Don't we have energetic particals that have no mass?

is that not the way it is ? ie if time stops at c then the photon is instantly at the other side ?

i guess we live in a fractured fallen shadow of the real world where light lives

My best guess would be "yes".

If we lived at light-speed, we would live all of our entire life at one instant.

No, it's not in effect. The wormhole idea was developed for Sagan by Kip Thorne (I think that's who is credited). The idea is a sort of a bridge between two points of spacetime.The question is, whose instant?

lol if there is no time at c then there can only be one instance!!!

mine!!!

one love....

As to seeing the ship frozen in time... This is hard to grasp for the following reasons:

The ship starts out a minimum set distance from earth in space. Lets just say this point provides an instantaneous image for our viewing pleasure.

At this motionless state, it is emitting a constant light image of the craft which is traveling at roughly 300,000 km/s. The coordinates of the ship is the source point for all the light providing this image.

The ship kicks into light speed, ignoring acceleration time.

One second later, the ship is 300,000km away, and the object that was providing the image is no longer present in the same spot.

The light once provided by the image must reach us and then change relative to the ship's motion. How can the ship appear frozen in time if it is no longer present?

If the ship away from us at 300,000 km/s and light moves toward us at 300,000 km/s, we should experience a time dialation, but we will still see the object receeding.

Consider a fighter plane moving away at 500 m/s and firing missiles aft at 500m/s every one second, just as the ship/light traveling at indentical speeds in opposite directions.

1s - 1st missile position 500m
2s - 1st missile position on target, 2nd missile postion 1000m
3s - 2nd missile position 500m, 3rd missile postion 1500m
4s - 2nd missile position on target, 3rd 1000 m, 4th 2000 m

1X ->

2X- ->

3X - ->

4X- - ->

5X - - ->

Missiles arrive every 2 seconds even though they were fired every one second.

Now given an infinite number of frames of course with actual light and ship, but would this not be the way it happens? Wouldn't we see the light of ship in 1/2 time elapsed and not frozen?

This is the same reason I don't understand the description of the event horizon of a black hole. Sure, the light would be suspended there, but since it is trapped and frozen, the light can't reach our eyes. As to the slow-moving light infinitely escaping the point just before the event horizon, it is also receeding and diminishing infinitely. The object gets trashed and compacted but leaves it's signature behind in the event horizon. The output image has to get fractionally reduced in brightness and clarity forever until it is undetectable and negligible. Nothing can duplicate energy from nothing, and recreating an image from a non-existant object violates multiple laws of physics.

And even when you state it in its most extreme case you cannot see that it is PURE Sci-Fi

Time does NOT stop just because something is traveling at "c"

Everything is 'Relative', including a single photon traveling at "c".

Even though that single photon has 0 velocity, in its own frame, for every 186,000 miles it travels, 1 second of Time passes.

And this whole thing shows the absolute falicy in defining light in 'its own reference frame' as having 0 velocity, because that winds up defining the whole path of light from its source to its sink as "Instantaneous", which is "Impossible", even in its own frame!
