Sometimes I can't believe the speed of light...based on the image taken . That means we are not sure that the UDF423 is still there or not currently...the image is 10billion light years distance..mindfucuk

That means again, if the galaxy is not there anymore perhaps 9 billion light years ago, we still can see the same light and shape of the galaxy for 1bil light years eh?

theoretical, yes.

if alien watching earth from few million light years away, they will see dinosaur something

But bro, the picture is taken with hubble right? What if we have the tech to zoom the picture, moving object until can see the land? Just like google map/ satellite...this sure can prove the real time activity and update over there is it..We are not capturing the light, but the object.

Am I right.this is the thing that play in my mind..

What if hubble is being place at nearest galaxy and taking a picture of earth until zoom to KL area, basically they will see Yap Ah Loy doing business ? A history?

everything you see is light reflection. even with super zoom hubble still the same.

your second assumption on KL area should make sense in theory. depends how many light years away

So we are a part of light reflection...we are physically here but our movement is a part of light reflection. Is that so.mindfucuk my brain for a while.

errr ... I always thought that is a simple form 5 physic knowledge?

anyway, science is a cool way to discover things, hope this will ignite your interest in it.

yup, in theory.

and more mind fuck is light can be bend in universe. so the light you see from certain direction might not be the actual position. biggrin.gif

By naked eyes I can only understand that my boss 10meter away from me is 0.00000000001 nanosecond old from what I see.

yup.

speed of myvi is 9999km/h
speed of sound is 0.34 km/s
speed of light is 299,792 km/s

see, no matter what, the speed unit will bind with time (per second, per hour, ...)

myvi, sound, and light is visual thing, or 3 dimension element,
while time is another element, and often referred as 4th dimension
if alien can travel faster than light, means, they can get from point A to point B in real time, thus, they can see you in real time.
they can't see what u doin in future becoz your future aren't present yet = no light to project on presented object = can't see visual.
that's why, you can't go back to past time / future time
*
you cannot see future even you are faster than light. that is just a science fiction thing
