- when I came to think of it.. seeing from a very distant planet from earth (assuming I can live in that planet). And then I see earth.. just a spark of it then what I'm seeing is actually the past of earth ( 240 million years ago or so) applying the same principle from what I have read here.. cool.

an event happened approximately 240 million years ago and has just been seen.. wow!!!

If you look up at the night sky, most of what you see happened thousands, if not millions of years ago. When we look up into the night sky, we are seeing mostly the past, and not the present. That star you're looking at might have exploded or winked out thousands of years ago--what you're seeing now is light that started its journey thousands of years ago and just now, hitting your retina.

Thus, if there are some alien civilizations out there, who are of equal technological standing with us, then if they are able to point their telescopes at our Sun, and let's just say they are a little more advanced than us in terms of optics, and they see earth, they might see a "lifeless" world, if their distance from us is equal in years to the pre-Cambrian period.

cool kaayo.. murag feeling nimo nibalik ka in time... laliman ka makita nimo ang usa ka event nga nahitabo na sa past.. he he..

and if they can travel many times faster than the speed of light and visited us, warningan ta nila sa mahitabo, unya sa sunod nila nga tan aw sa ila super telescope, dili na lifeless nag earth? posible kaha ni?

Fact 1. Nothing can travel faster than the speed of light

Fact 2. Warningan sa unsa? You're forgetting that they are seeing the PAST, not the future. You mean they'll warn us of our past? LOL

- OT: we just got confused.. i guess hahaha
- Maybe someday we could attain to travel faster than the speed of light...but that's another story.

Correct me if I'm wrong, di ba we are sending messages/signals/transmission to space?
So, ang makita sa distant stars/planets ang mga transmissions way back 19forgotten.
If any advance alien civilization received our transmissions, they might think we are less advance with the signals that they received.

Not if they're advanced enough to KNOW that the transmissions they are hearing are indeed old.

amazing...

question: how far can light travel? naa ba sad calculation kanus.a muhunong og travel ang light? kung wla na makita nato ron katong ni explode na star does this mean ang journey sa light ni end napud?

bitaw, nice point. mohunong ba kaha ang pag.travel sa light? like ana nga dugay na kau 240millions years na. ug asa kaha kutob.

[cromagnon]

that would be right actually if you look at the following

saturn - 1.43 hours or so ago
sun - 8 mins and 20sec ago

what more na kaha ang farther place

like if u look at the nearest galaxy to us Andromeda
that would be 2.2 million years ago

bitaw, nice point. mohunong ba kaha ang pag.travel sa light? like ana nga dugay na kau 240millions years na. ug asa kaha kutob.

I think its infinite

hope fully naa sa future
