if you travel faster than light and put your headlights on, do they work?If objects are moving away at faster than the speed of light, how does the light from them get back to the naked eye in order to view them?
Before the rate of expansion was that fast, the light will have made it across to us. Post-C that light will never reach us. The light we still see is billions of years old so we will always see billion year old light until thet point is reached and we stop receiving their light.If objects are moving away at faster than the speed of light, how does the light from them get back to the naked eye in order to view them?

You realise that every system up in the sky we see may not be in the state we see right now as it's the system as it was millions or billions of years ago and it's that light which has only just reached us, right?!
I'm pretty sure the light will still reach us. Light doesn't work in a way that would seem to make perfect sense; for example if you were moving away from Earth at C+1m/s and shot a laser at the Earth, they would still see that light. Equally light doesn't exceed the speed of light when you walk forwards while holding a laser pen.
But what the expansion of the Universe will do, especially since the expansion is accelerating, is the following two things:
Today, the farthest away we can see is 46 billion light years: the current visibility limit. We can calculate the future visibility limit as well, and we find it's about 33% greater than the current one: 61 billion light years away. Based on how volumes work, this means we will someday have a total of around 4.7 trillion galaxies to view, as given enough time, that ultra-distant light will someday arrive.
- It means that there is a limit, in the future, to how far away we will ever be able to see distant objects.
- It means that there is a limit today, and that limit changes over time, to how far away a galaxy can be today and still send new light to us.

Yup, because the speed of light is constant, independent of the speed of the objects around it.
The galaxies are not moving within the universe at greater than the "speed of light". You can invoke your god all you like, but that won't cut any ice with me. I'm an atheist - I don't care what you claim your god says or does.
What are you disputing when you demand "my" facts? They're not mine, by the way. They're reality's facts, as far as anyone can tell. Are you disputing that the universe is expanding? Are you disputing the rate at which it's expanding? What, exactly, are you disputing?
I suppose I should watch the video you refer to...
...and, unsurprisingly, it doesn't support your position. He's saying the same things I've said (examples 1 and 3 in the video - example 2 is quantum entanglement, which is outside my understanding entirely). He even states that the expansion of the universe doesn't allow for space travel at speeds >c, which is what you were claiming it would allow.

I did say start from 6 mins in..
I SAID THAT OTHER THINGS CAN GO FASTER THAN LIGHT!! WHAT PART OF THAT DON'T YOU UNDERSTAND?
So you disagree with Don Lincoln? https://en.wikipedia.org/wiki/Don_Lincoln and the rest of the bunch?
If so. Where is your facts? or where did you read\learn you facts from?

Those galaxies are not moving faster than the speed of light..
That doesn't fit with any of the recorded testimonys though. Not one little bit.I think I've just solved the entire mystery
The USS Nimitz incident with David Favour apparently occurred on Nov 14th 2004, around 100 miles roughly off the coast of San Diego. That same week, NASA were testing the X43 Scramjet which can do Mach 10, and it launched from a B52 and accelerated to around 110000 feet, until it splash lands into the Pacific ocean, which is in roughly the same area as the Nimitz and it's battlegroup were, somewhere off the west cost of the US, certainly within distance of the jets. It wasn't recovered.
The times and dates don't match up exactly, but it does line up with the sort of thing we're talking about - a white object which moves at incredible speeds, being tested roughly within the same area, roughly around the same time David Favour saw some 'stuff' give or take a couple of days.
Throw in a few inconstancies, perhaps some misinterpretations and some abnormal instrumental readings (might be expected from an object traveling at Mach 10) and miscommunication between the people doing the tests and the Navy, to me it seems like quite a plausible and reasonable explanation. Lets also not forget, that David Favour might have spun his story a little to gain attention, although I can't prove that - it's not such a great leap.

The test document is also quite interesting;

It also makes sense, that NASA could have been made to keep the test a secret from the Navy; What better way to test the systems and crews of a carrier battlegroup, than to troll them with an object traveling at Mach 10, that they've seen before, during drills.
You'd get maximum millage out of the test, and you'd get to see whether the Aegis Radar would see it, how the F18s reacted to it, could they track it, etc. It's a brilliant test.

The fact that German scientists in WW2 had knowledge and technology so vastly superior to the Allies that it might as well have been stone age warriors fighting Warhammer Space Marines is why Germany won WW2 so easily.
Er..wait, that didn't happen.
I started from 6 mins in and he specifically says that the galaxies aren't moving faster than light, even though the distance between us is increasing at a rate faster than the speed of light. It's a nuanced difference. This is because the fabric of space, what all matter sits in, is stretching and it's that stretch, not the speed of the galaxy itself, that is causing the distance to grow faster than the speed of light.
According to Einstein matter [stuff] cannot travel faster than the 'speed of light', and we still believe this to be a correct fundamental principle of physics. But the fabric of space is 'nothing', it's not matter, so it's not constrained by this law.
So no, "things" [matter/stuff/real objects] cannot themselves travel faster than light.
Distant galaxies will blink out when the intervening space between us stretches faster than light, at that point no new light emitted will reach us as it's speed is slower than the 'medium' it is moving through.
Theres plenty of footage of the german experimental technology on tv, a lot of it was in the prototype stages and could have led to something given time. Because this was happening towards the end of the war, there wasnt enough time to complete research, so their prototypes went up in flames.... Much like their zepplins...
Its very plausable that the technology was found and investigated further by the US, leading to nothing or something
Well even the Hubble telescope has seen this. http://www.stsci.edu/ftp/science/m87/press.txt
"We see almost a dozen clouds which appear to be moving out from the
galaxy's center at between four and six times the speed of light."
Even these tell the same thing using math. http://curious.astro.cornell.edu/le...rom-each-other-faster-than-light-intermediate
And what if Einstein did not get it all right?
