A light speed question...
 

When a spaceship travels in light speed, there is no danger of collision...As soon as the spaceship goes to normal speed it finds itself in an asteroid field and collision is imminent...

Your thoughts...

Re: A light speed question...
 

Why is there no danger of collision at light speed?

Light particles/waves are constantly colliding with objects - it's how a mirror works.

Re: A light speed question...
 

What if the normal speed of the spaceship is lightspeed?

Re: A light speed question...
 

Someone's been watching The Empire Strikes Back.

Re: A light speed question...
 

Still, doesn't make sense...

Re: A light speed question...
 

The Millenium Falcon made the Kessel Run in less than twelve parsecs, but still, it is a fast sprinter but that don't mean it only sprints...It can walk too...

Re: A light speed question...
 

No...A New Hope...Hopefully Empire will be on after this...

Re: A light speed question...
 

Well light obviously travels at the speed of light, and manages to collide with objects - it can't pass through them. (Excepting special cases eg glass etc.)


A spaceship would disintegrate if it hit a large enough object at speed, including light speed.

Re: A light speed question...
 

Those aren't asteroids, it's the remains of Alderaan.

That's no moon....

I've got a bad feeling about this...

Re: A light speed question...
 

Exactly...So how come in light speed the Millenium Falcon is not in danger, but as soon as it is in normal speed it starts dodging asteriods in the field...

Re: A light speed question...
 

You also felt the tremor in the Force???

Re: A light speed question...
 

Anyway, a theoretical way to travel across space faster than light is to bend space and time with a gravity drive, bringing two points closer together...or maybe use wormholes with a Stargate at each end...or travel in a different dimension/universe altogether.

Yes, as if a million voices cried out and were suddenly silenced...

Re: A light speed question...
 

Hot damn...

Re: A light speed question...
 

I presume this is a film?

They don't always stick with the facts you know.

Re: A light speed question...
 

Don't tell me you've never heard of Star Wars!

Hot damn indeed, my young padawan. Of course, the energy required to bend space and time is inconceivable...maybe a million of ours suns. I'm sure SYB has something to add to this.

Re: A light speed question...
 

or Spice.

Re: A light speed question...
 

Not just any film; Star Wars!!!

Re: A light speed question...
 

Will wait for our Yoda to comment...

Re: A light speed question...
 

I can honestly say I have never seen it, nor have I any desire to do so. Isn't it just a 'cowboys and native americans' transferred to space type film?


Now '2001: A Space Odyssey' .....that's a film.

Re: A light speed question...
 

Oh god...You must be from Tatauine...

Re: A light speed question...
 

The scene with the chess pieces killing each other always bothered me..

Re: A light speed question...
 

Actually, not even close...

Re: A light speed question...
 

That's Alice in Wonderland...You're talkin' hyperspace shit now...

Re: A light speed question...
 

The 'good' guys dressed in white fighting the 'bad' guys dressed in black....?

Re: A light speed question...
 

Ah, but it's not as simple as that. It's a story of fall and redemption, faith and love, wookies and ewoks...

Re: A light speed question...
 

And also green lightsabers and blue lightsabers...And also red lightsabers...

Re: A light speed question...
 

Bonny Boy- seriously how can you not have heard or seen space wars? it was the first film I saw at the cinema as a kid, I loved Luke Skywalker for years, then as I got older preferred Hans Solo and I think at one point I had a thing for Darth Vader.....and every man I've ever known loved Princess Leia!

It may be a bit dodgy but it is an absolute cult film/trilogy... not so sure about teh new ones and I think whoever created Jaja Binks should be shot!

Star Wars rocks! :thumbup:

Re: A light speed question...
 

Not forgetting bad ass Mace Windu's throbbing, purple sword.

Re: A light speed question...
 

That guy was a pimp...

Re: A light speed question...
 

I only found out yesterday that Darthvader is Luke's Dad:ohmy: AND princess leah is Lukes twin sister!!

Re: A light speed question...
 

I found that out for the 3rd time on Saturday...

Re: A light speed question...
 

What's this got to do with sex...your'e off at a tangent ! :unsure:

Answer: the shields are at 100% as in Star Trek...so things just bonk off !

Re: A light speed question...
 

That time of year...

I also want to know, why don't put on seatbelts when in their spaceships, but in fighters they're fully strapped...

Re: A light speed question...
 

No it's not - I don't believe Akira Kurosawa was into westerns... redemption and revenge yes, stetsons no... George Lucas may have liked such things, but Star Wars was pretty much based on The Hidden Fortress and Kurosawa's Seven Samurai (so was The Guns of Navarone, Ocean's Eleven, The Dirty Dozen, and the western remake The Magnificent Seven)...

Re: A light speed question...
 

when you travel at the speed of light time stops... but to reach light speed your mass would have to approach zero otherwise the momentum / inertia would be too much

or

engage warp drive with the dilithium crystals...

or

the Infinite Improbability Drive where anything can happen....

do you know where your towel is?

don't panic.

Re: A light speed question...
 

If I understand things correctly, when an object travels at the speed of light, time passes as normal in the reference frame of that object.

For a stationary observer, however, the measured time of that object will be longer by a factor proportional to the square root of 1-the ratio of the square of the object's speed over the square of the speed of light. According to the laws of mathematics, when the object's speed is equal to the speed of light, then for every tick of the object's clock an infinite amount of time will pass for the observer. Some physicists argue that this makes light speed travel for a non-zero mass particle impossible - ref the twins paradox.

There is, however, some experimental evidence to suggest that a particle called a tachyon does exist - this is a massless particle that travels above the speed of light.

That's pretty intriguing, because the math then says that the time dilation factor becomes the square root of a negative number, i.e. an imaginary number.

In math terms, that means that the time vector becomes 90 degrees out of phase with our own vector measure of time. In other words, it gets completely de-coupled from our own measure of time.

What that math translates to in terms of our human experience of time, I have no idea. Nor does anyone else, I believe.

Oh, and the same factor applies to the dimensions of the object too. As an object travels at greater speed, it's apparent euclidean dimensions also shrink.

Mind ****, eh?

As I always say.............. if you're not sure, ask Eric Idle............

Sci Fi geeks eh!

Oh, go and design me a new pair of boxer shorts if you've nothing more worthwhile to say....
