They say it takes light years to reach us so when ever a star arrives/dies out we won't know for another 4.3-100 years.I know scientists are smart but isn't there a speed of sight?How fast you see things, I mean isn't it almost impossible to see what's not there be there? Well anyways, were "Time traveling" if you want to know, because when we look up we are viewing the past.
I guess? I always think of it like throwing a sack of Pepsi cans at someone. ----- You threw it. ... It's flying across for a couple seconds. ... It hits em in the rear while they're running away. ----- Just with light and years.
As sight is light hitting your eye, the impression going to your brain and so, the "speed of sight" will be an itty bitty slower than the speed of light.
No, there is no speed of sight. You 'see' what light particles touches your eyeball, nothing else. Your brain assembles the image made up of these pieces of light, and defines it for you. If your brain is wacked out, you see stuff that's not there. It's called a hallucination. In fact, there are things that are there, that you do not see, as we only perceive a portions of the spectrum.
MudPuddle is right. It would be like shooting a paper plate with a gun. The gun is the object (such as a star, the bullet it the light, and the plate is your eye. Your eye perceives the info when the bullet hits the plate and no sooner.
If light particles from a star or something suddenly stopped 1/32 of an inch from your eye, you still would't be able to see the object. Of course it would be a great mystery if the light particles suddenly stopped for no reason like that.
Very so, JoHn. The speed of light is finite, thus only being able to travel a certain speed. This way it takes time before it hits the eye. In some weird way you could say that you will never see the present, though it is what we see that makes the present.
Yeah and if a star dies out or a new one forms, we won't know for about 65 or somewhat years, and someone said space is a form of time travel, because itt akes a while to do stuff.Brought it up here because i dont want to start a new topic and it's about space.
He is talking about at night, not day. And did you know that the sun could have disappeared minutes ago, and it would be impossible to tell (if it was day) because it takes light even from OUR sun 7 minutes to reach the earth. You know what would be really weird? If a star like Polaris or one of the stars in the dippers died out, that would totally ruin the whole sky.
Another thing to look at, if you go twords an object far off at a high rate of speed, would you not be traveling into the future, also another thing to look at, if you move away from an object at light speed you would only see what you saw at the moment you hit light speed, meaning that from your position you have stopped time. And what would happen if you went even faster than the speed of light, would everything blackout or would time go in reverse, because you are catching up with what you saw.
A star cannot die out for 5 minutes, once it dies it supernovas and is destroyed, forever. And by died out I meant if we couldn't see it anymore, it might have already died out but it has no impact.....yet.
