Hubble detects possible spaceship

Oh ok, so we're looking at 4-5minutes delay?

I would have thought it'd be something of that order. I recall from the article I read that the scientists were excited and intrigued by this find, they felt sure they were witnessing a comet in the immediate aftermath of a collision with 'something' - possibly an asteroid IIRC.
 
just some info found on the net about light speed

According to Einstein's theory of special relativity, published in 1905, nothing can exceed the speed of light. That speed, explained Einstein, is a fundamental constant of nature: It appears the same to all observers anywhere in space.

The same theory says that objects gain mass as they speed up, and that speeding up requires energy. The more mass, the more energy is required. By the time an object reached the speed of light, Einstein calculated, its mass would be infinite, and so would the amount of energy required to increase its speed. To go beyond the infinite is impossible.

What's more interesting is the time dilation, as your speed increases you experience time more slowly relative to others, so when you reach the speed of light no time passes at all. You could travel anywhere in the universe in an instant from your perspective if you could reach C. Orbiting the earth close to light speed on a shuttle would be like travelling into the future.

that's exactly it so lets say it takes you a year to get out of the milky way when you return 5 years on earth would have passed.

the main problem is that to go at the speed of light you need an infinate amount of energy with anything that has a mass, which we dont have.

pulsars in the distant universe go faster than the speed of light, for us however it's somewhat impossible.
 
Nobody said it wasn't. :p

You agreed it happened hundreds of years ago though because of the time it takes light to reach here from extreme distances. :confused:


But it's about 8 minutes away so probably happened in the last few months before being noticed:p

i think he got confused tefal, 150 million miles is actually not that far in space terms.
 
so in essence, the sooner we create an anti mavity or anti mass device the sooner we can travel at light speed/time travel. Cool.
