Reply to Theoretically if we could instantly send a strong-enough telescope to a location millions of lightyears away from Earth, would we be able to see into our past? by Billy_bilo_
Short answer, yes.
Its not different from me making a big boom, and you standing far away. By the time you hear that noise, it was made well in the past.

Huh?
The sun is far far far away. The shadows it cast on the moon is not going to depend on your location standing on a rotating round rock.

Hmm... If my understanding of our best theory to date is correct (and the theory is correct), you probably cannot pull it back, as the direction "back" no longer exists as you pass the event horizon.
In reality the line would snap.

Any society that has advanced enough technology to detect, intercept and capture the Voyager probe intact will have no issues decoding it.

Most likely, imo none of them. The universe is probably continuously created and destroyed.
There is no repeating events even if time is infinite. However time and space are related, you cannot have one without the other.
Or we are all living in a computer game, and it's all just for fun.

If you believe that the universe is expanding from a much denser state (makes no sense, but whatever) and the rate is give by the Hubble "constant" (its not constant), and then calculate backwards (assuming a lot of stuff), then you get 13.8 billion years or so.
Its all based on the assumptions you want to pin your creation mythos on.

95% is "Dark Fudge" with current understanding. So needless to say, our understanding is severely lacking. Crossing fingers for warp-drives or wormholes is possible in those 95%, but I'm not holding my breath.

Reply to comment by BasicHelicopter7711 in Is the expansion of the universe significant enough to be included when calculating the trajectory of spacecrafts? by andreasdagen
I will as long as people still buy into the hopeless Big Bang hypothesis
or dark energy is actually found.
Whatever comes first.
In the meantime enjoy the modern creation mythos, its even less likely than the one found in any old religion.

An expanding universe has never been measured. It is just a hypothesis inferred from redshifting of distant light + Big Bang hypothesis, nothing more.
To explain the issue of why the expansion isn't measurable, a bullshit explanation about galaxies being "gravitationally bound" has been introduced.
In short; no adjustments are needed, as spacecrafts does not need to adjust for hypothetical forces.

Its easier to understand if we scale things down a bit.
Imagine the sun is a grain of sand on the beach, at this scale, the earth is 15 cm away and invisible.
At that scale the nearest star is 40 km away.
And the center of the galaxy is 2/3 the way to the moon.
Galaxies are extremely sparse objects, so nothing will really happen as far as collisions go.

Not really. You can have an infinite universe, but still have no stars shaped as a pyramid for example.

Yes, the circle you stand on would be "flatter", as it is bigger, so you see further.

I guess they bought the camera when they started the project. So it is 25 years old now.

Do you think life on Earth is imminently going to end?
This is a very common thing that humans have thought for millennia, and has been proposed and supported by the experts throughout the times. And despite all the noise, there is nothing indicating that this is in fact going to happen.
Think we'll see any hint of interstellar colonization in our lifetime?
Haha, no chance in hell. Maybe by the end of this millennia, aka 2900 or thereabout. If ever.

I don't think humans will ever leave this solar system.
There is nothing indicating that anything but slow-boating is possible, and it is meaningless for humans to do such a thing.
Of course we will invent immortality and self-aware AI first, as neither of those are particularly difficult compared to interstellar space travel.
So when we have both immortality and self-aware AI, we will send something out that won't get bored to pieces for 1000 years while waiting to arrive at the nearest star system.

You can expect the correct answer to this, when we have figured out everything about the universe.
We have about 2% figured out.
So any answer you'll get is going to be wrong.

No, but it is part of the "best" theory that cosmologist have at the moment.
This "best" theory manages to explain about 5% of the world, the rest needs Dark Fudge ^(TM) to work.

Yeah, that's why your theory sucks as much as the current one.
Mythical one time event that magically created the world.
No wonder it was presented by a priest.
