Seeing things in their past? You are full of beans!

[Jumi]

You want to hear things in the past? Look at an explosion a km away... you'll hear it later on.

Well this is all time I could have spent beating my head on a wall.

He has that effect on people.

 

[james blunt]

Object is moving at 0.5c toward us.
Object is 1 ly away -> 1ly/0.5c = 2y to arrive.
Object is 2 ly away -> 2ly/0.5c = 4y to arrive.

Correct

Considering one way yes.

Think two way instead ,then you may get it and surpass your Ai programming.

 

[BSM1]

No, that is odd.

So you are saying if I could travel at c, for 3.154e+7.s, I would not have travelled the distance of 1ly?

You are mistaken.....

Even if you traveled in a circle?

 

[james blunt]

Even if you traveled in a circle?

yup

 

[Polymath257]

The reason for this?

Because space is not a vacuum.

No, the bottle would not be crushed because the pressure inside (vacuum, so zero) is the same as the pressure outside (vacuum, so zero).

If you put some air in that bottle,

Equivalent being the give away there.

The correct semantics would be


a unit of astronomical distance equivalent to the time that light takes to travel that distance.

299 792 458 m = 1ls

6 million million miles = 1ly

OK, let's go with this. What is the time equivalent to the distance to the moon?

 

[Polymath257]

Ok let us make this simplified,

I throw a ball to you and it takes 1 second to travel the distance between us.

Simultaneously you throw a ball to me at the same speed and it takes 1 second to travel the distant between us


1) The balls arrive at their relative destinations at the same time

2) The balls arrive at their relative destinations at different times


Pick one?

The correct answer is 1. Now, what is the relevance of this to your original question?

About 1 second at c I think

~1.3s to be more precise.

 

[Jumi]

Correct

So the original, you confused years and lightyears?

 

[Polymath257]

About 1 second at c I think

~1.3s to be more precise.

And at a different velocity? Say, .5c?

 

[james blunt]

And at a different velocity? Say, .5c?

~2.6s

[beenherebeforeagain]

Geez! just saw how many pages of posts have been put up so far...sorry if I missed anything interesting...

We observe an object travelling towards the Earth that is 1ly away . The object is travelling at 0.5c towards us.

Said object is traveling at .5c, and takes two years to travel one lightyear.

The light we initially detect was emitted/reflected when the object was 1 ly away. That light is traveling at c, and took one year to get from the object to us. during that year, the object has approached by .5 ly, so at the time of detection, it was already .5 ly away.

Assuming no change in velocity, it will arrive one year after it was detected.

I think...

 

[Polymath257]

~2.6s

So, with one velocity, it is 1.3s and for another it is 2.6s. So, the distance is NOT a time. The equivalence depends on the specific velocity?

How is this picture relevant to what you asked previously?

 

[james blunt]

No,because we are discussing a light year , a specific quantification.

 

[Thermos aquaticus]

No,because we are discussing a light year , a specific quantification.

If someone fired a gun at the earth from 2 ly away with a bullet travelling at 500 m/s, are you saying that it would take two years to reach the Earth since a ly is a measurement of time?

 

[stvdv]

A second is equal to ~0.288 miles/s , you really don't know do you how poor some science is ?
24900 / 86400 = 0.28819444444 miles / s
You have 1.s = 0.28819444444 miles / s
The speed of time 1000mph

Aha, I understand it now. Not even units Sustainer gets right anymore.
I was already wondering how it comes we don't see more illogical things of sustainer.
But just one hour after "Terran" wrote the post "I am the man of the prophecy"
Sustainer woke up and started one of his non-sense posts
He just can't stand someone took his place it seems to me

My God, spiritual ego is on the rise on RF I can see.
Bad development. It's warned in the scriptures that this is incurable and biggest obstacle to spiritual life
So have fun with it

But I am out of this non-sense ego tripping on RF

Huh? I see the distraction has arrived.
