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

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

The object takes 2ly to arrive, if we were seeing that object in the past, it would not arrive in 2ly, proving ''you'' are full of beans and are incompetent at ''your'' job.

Light years are not a measure of time, but keep trying.

Two photons are emitted simultaneously the opposite directions from two points precisely 1ly apart.

The clock starts at 00:00:00

Adam is on the left and Alice is on the right

When does Adam see Alice?

When does Alice see Adam?

Realisation is acceptance of the truths.

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.....

T%hat isn't what you asked, and it isn't what I said. Light year is still a distance, not a measurement of time. If you are travelling at C, by the way, you don't perceive time as advancing at all.

Which should show you why light years can't be measurements of time. You have a think for a bit.

How?
A light year is the amount of time it takes light to travel a distance, the distance is a constant and c is constant. The amount of time is the measure ....and can you answer the question or are you going to avoid it in avid fear of validating my claim ?

No. A light year is the distance that light travels in a year. It is not a measure of time.

How do you compensate for gravitational lensing and the fact that light can be altered, redirected, and stopped entirely?

You first said it is a distance, now you are saying a light year is the distance that light travels in a year, now you are not explaining it is a distance, you are now explaining it to be a binary process.
Discounting time altogether, why are you ignoring a ly is a tri-linear process?

1) Time
2) speed
3) distance

A light year is a time and a distance, it is both is it not?

Nope, it's just a distance. The distance that light travels in an Earth year. An Earth year is a largely arbitrary measurement of time, to wit, the time it takes Earth, (our planet) to orbit the system primary, i.e. the Sun. There's no "tri linearity" involved. A light year is simply 9.5 trillion kilometres (give or take) or,m if you prefer, 5.88 trillion miles. That's it. No more, no less. No time measurement involved. It certainly is not a measure of speed.
