If time is equal to the distance that light travels, yet slows as one approaches the speed of light, does this not indicate that the speed of light is actually timeless?

If the speed of light is timeless, yet time is equal to the distance that light travels, does it not mean that the observer is responsible for the conception of distance in relation to light?

If time is equal to the distance that light travels, yet the speed of light is timeless, than space/time is actually light, as a measurement of time is actually a measurement of light.

If a measurement of time is actually a measurement of light, but the speed of light is timeless, does this not mean that to measure light is to create time?

Theoretically, if one could obtain a unicorn that could wish you to the nearest star system...

It doesn't even make sense to say "if one could go beyond the speed of light" and then ask if anything would happen because it's impossible to even answer that question.

Even your imaginary unicorn would have difficulty, the top equation is time dilation at constant acceleration.
c= the speed of light, v=velocity. If v<c, you end up with an imaginary number.

It's relative.
If you yourself are traveling the speed of light, the closer you get to c, the slower time gets for you only, the rest of the universe starts to fast forward.

I guess a photon itself would be a timeless object, it has to interact with something to change.. but nothing quantum mechanical exists singularly, it exists in the context of the nature around it.
I guess in photon time, the universe is only a tiny fraction of a second old, if that is even an accurate description.
But the rest of the universe still matters.

The way I think of quantum mechanical objects is that they aren't like a ball or anything concrete like that.
A beam of electromagnetic energy is like a river.
You can run up to it with a glass, take a scoop out, and proclaim you have an electron.
You are measuring the location of that electron, as it is in your hand, but it's not going anywhere. You could then spill that electron out of the glass, back into the river. Although you don't know where that electron is anymore, you could figure out what it's speed is and where it is likely going based on the contours of the river, or getting out of the metaphor, the physical nature of what is going on around it.

Photons are only timeless to themselves, the rest of the universe collapses any notion of them existing in a timeless place.
If light didn't exist in time, I imagine, if the universe was able to form in the first place, it would just look like a big clump of white noise

I've noticed this a lot when people take about outer space and the universe they always like to mention how "insignificant" it makes them feel.
"Yeah man space, wow, you know it really puts my life into perspective; how insignificant we are in the grander scheme of things."

This is my opinion but I think that's such a belittling thing to say its also unsettling how common it is a thing to say when talking about the universe.

Granted the universe is huge, and in comparison us tiny humans are very very tiny. Doesn't make us insignificant though, or our lives meaningless.
You are the most significant person in your life, because without you, your life wouldn't exist. Who cares if you don't become famous or invent something that changes the world, you are the universe experiencing itself through your life, defining it with every thought, action, emotion and experience you have.

Sure you are a tiny droplet in an ocean of water, however what is an ocean but a multitude of droplets?

I believe the whole point of this is about the journey not the destination. I also believe you cannot have nothing, because you need something to experience nothing to know nothing is (or isn't) there. All there is is consciousness, and when we die from these lives of our consciousness will continue for eternity. This universe may also one day go cold but still consciousness will always be.

What you say also defies the first law of thermodynamics. Which is a weak argument because that "law" is just some physics rule we humans made up to help us understand something we didn't know anything about not too long ago - our universe. Energy cannot be created or destroyed, only transferred. Perhaps if the universe does go cold and all the matter decays into its original form, consciousness, that's when the whole process of the big bang starts over again. When there are no more potential situations to happen because there are no more bits of matter, a state of pure consciousness. The creator, God, whatever you wanna call it.

But ya, we're significant because we're those bits of matter being experienced by God through our eyes, defining itself to itself

I disagree, what he said makes perfect sense. Black holes are impressive by their sheer magnitude, but are simple objects and--given what we know about mass and gravity--are pretty much inevitable. Flowers, on the other hand, are fucking complicated on many levels and its a wonder such a thing ever came to be at all.

Still though, I can wrap my brain around a flower, but I'm pretty sure trying to truly comprehend the sheer pan-celestial magnitudes of mass, gravity and density that is a black hole would be a veritable Lovecraftian experience.

if one were traveling above c in a ship using an Alcubierre drive, would they experience time dilation?
as i understand it, the object affected by the drive isn't moving but rather space is simply expanding and contracting around it. the object has no velocity and isn't moving in the normal sense.

No, because the entire ship is contained within it's own stationary spacetime bubble.

The negative time generated by dilation will only speed up the journey relatively to the speed of light.

I think aliens might just be too different and advanced for us to even recognize as life and they might be able to travel around so fluidly through the universe that it's not that they are visiting us because we are such fascinating creatures, they are visiting here because they go around everywhere all the time anyways, I'm sure they spend time on Jupiter too

A crack pot idea I was thought of last night is this: There's some good reasoning out there that the universe exists as described by a model of the holographic principal, there have also been some recent papers that suggest the phenomenon of volume and orderliness in space is created through entanglement of information on the holographic cosmic horizon that we are all smeared across.

My idea is that aliens have some sort of super quantum computer (or something beyond that) that can decode all of cosmos and they are able to somehow alter the entanglement states in order to manipulate the properties of volume. I bet they can create black holes like it's nothing.
But I think that would explain the behavior of UFOs, from how they seem to morph shape, and split apart and reform. They are so hard for people to describe because they are taking quantum phenomenon and blowing it up to real world levels. I think when a UFO "explodes" without leaving a trace, it's just some inherent collapse of the system of altercations to the holographic horizon normalizing itself.

Granted that's all assuming UFO reports are even accurate, but like I said, crack pot, it's just fun to think about even if it's not real.

It would be an interesting statistic to see how the numbers change from populations with lots of alien cultural references to others were it's less prevalent, and how it changes with the scientific education levels of the respective populations effect the out come as well.

I've seen one ufo, it was probably a meteor, about twice the size of the full moon, comparable color and brightness, but it didn't have a tail and it flew right over me. I've seen large (good fraction of the full moon size) meteors before, and the big ones still had tails, but maybe it was a simple perspective issue, as the ones I saw with tails were all on the horizon. It still scared me though and I'm a super tough guy whose not afraid of anything

Yeah, but we're really far away too. If we were closer (and blocked out light from other sources, we see dim objects near very bright objects by covering up the bright object), some structures would be brighter, to an extent.
But nebulae are so big and diffuse they've be invisible up close. The face of OP's unicorn is about a light year long.

The IAU currently does not recognize space-unicorn as an alternative to light-year.

They're definitely *real*, but they're not as visible as the photos make them appear. Most of those awesome nebula photos are long exposures, yes, but they're also composites of infrared, x-ray, and visible light, with some coloration and hue/contrast added to make them "pop." It's a real thing in the photo, but it's not the "natural" way it looks.

This is a volcanic vent in Antarctica. The area around it is not habitable. The planet will become colder than that.

Geothermal and nuclear plants are the only methods of any scale that could be run for years if there was a catastrophe.
If there were enough proximity, farms could be set up in underground salt mines to last a few years.
Ultimately, nuclear and geothermal are the only power sources that aren't derived from our sun.

If my imagination is allowed to run wild, I would put the earth in orbit around Jupiter, close enough to cause a decent amount of geologic activity and keep some sort of an atmosphere, even if it's toxic and much less dense than ours is today.

The center piece of civilization would probably be fusion/fission nuclear reactors, we could mine hydrogen from Jupiter. But we would need manufacturing hubs, mines, and genetically modified plants in vertical farms. I think it might be best to put residential areas around hydrothermal vents. But the other stuff will probably need to be above ground

>But without the new model actually fitting the available data, the theory is as useful as the polemic model.

It was Kepler's vision of God communicating with mankind on a cosmic level, via recognizable geometric shapes, that incessantly drove him towards the pursuit of knowledge. He struggled through war and personal strife to get the data, not because he wanted to prove elliptical orbits (that part was incidental), but because he wanted to prove that his starry-eyed dream of a physical connection to the spiritual realm was true.

>When Greek philosophers said "lol if we divide something enough, surely we'd get to a point where we couldn't divide it anymore",

It was their way of estimating the area within complex shapes and it worked well enough for that purpose, unlike anything before. It worked so well, the Chinese reinvented it hundreds of years after the Greeks did.

People really screwed up when they made the assumption that the ancient Greeks knew all the answers, and any questions about the metaphysical weren't to be tolerated if they didn't conform to the religious teachings of the time. (seeing a pattern yet)

>"what if the universe is a high-dimensional object constantly rotating within itself" doesn't make any testable predictions, explain any data, etc.

But it might make people take the same data that's in front of all of us and see it in a new light. And as history has repeatedly shown, they might even stumble upon a world-shattering discovery in the process, which happens to hold true in reality.

You're confusing a few things there. Inflation is not the expansion of the universe, it was a very rapid stage of expansion in the very early universe which ended shortly after. What drives the expansion of the universe is like momentum, it was expanding so continues to now. What drives it's accelerating is a different question loosely dubbed dark energy which is really a name for any model which sets to explain it.

No. He didn't have to do anything, he chose to. Just as you chose to neglect the fact his data was stolen and accuse me of ignoring history. Pot? Black?
Personal difficulty does not change the facts, Kepler was brilliant but the data was stolen.

And no the sentence "the universe is a high-dimensional object constantly rotating within itself" isn't going to cause anyone to stumble onto some new cosmology, it's so vague it doesn't many anything, it's technobabble.

Yes, some things you morally HAVE to do(would you watch your significant other (or self) be tortured over and over again, while unbound and free with a cell phone? No you'd be compelled to do something different, or your guilty of doing nothing when a huge injustice is being done(injustice is an open ended term I know) and you can do something about it... Or guilty of being a sadist/masochist.

So if I'm correct, every galaxy has a supermassive black hole at the center of it. Every galaxy was once an active Quasar and then cooled after the black hole at the center of the galaxy spewed and consumed all the matter around it. So if a black hole has angular momentum at the center of a galaxy, does that mean the galaxy would result in a spiral shape? And would non rotating black holes instead form more of an irregular galaxy shape? I'm thinking in terms of galaxy evolution and the various shapes different galaxies take. Cheers.

That fucking pic. I always knew the galaxyy was huge. Had no real concept until I started playing elite dangerous, the playable world contains the estimated 400 billion stars of the milky way. Viewing the map is an awe inspiring and simultaniously crushing experience. Now I see this fuckin pic.

Why do we still live on one planet?

Eventually the spiral forms take shape of malicious code and Avira antivirus will detect them as false positives, You should try a Linux Distro, OP.
Just sayin'

You're both sort of right. Before major mergers when galaxies shave a lot of gas and are actively forming stars most of the big ones are spirals, some of the small ones can be irregular bit that's a different story. Left to it's on devices a spiral will not evolve or normalise into an elliptical.

A major merger is when two roughly equally sized galaxies collide and merger. It is believed elliptical form major mergers of spirals. As part of this merger the gas is usually stripped out and star formation shuts down with nothing to make stars out of (After the merger is finished). When it reaches a steady state it will be an elliptical, it will not evolve back into a spiral. The reason ellipticals have older stars is because they don't form any new ones, the oldest stars in each galaxy will not be significantly older or younger than the other.

Frame dragging is a tiny effect, it doesn't affect things like that.

I just started work at MIT, working on the Transiting Exoplanet Survey Satellite [TESS] program. Ask me stuff about space & shit, I can answer it for you.

Do you feel the current method of detecting planets in the habitable zone is exhaustive enough to extrapolate an upper bound on how frequently rocky planets where water exists in all three phases occur, at least for certain classes of stars?

Also, did you get a cool mission patch?

Good question!
This mission is designed to find candidate star systems for follow up observation by more sophisticated telescopes, like the JWST or GMT. What this means is that our mission is to simply characterize and catalogue as many candidate systems as possible. After speaking with a professor on the program yesterday, he explained that simulations of one year of operation showed a potential catologue of up to 75 earth mass exoplanets, up to 150 between earth and Neptune mass, and more in the Jupiter size class.
However, These candidates are going to be in orbit around the best candidate stars for water to exist, namely red dwarfs and smaller main sequence stars. It is hard to say which ones could have all three phases. At least what TESS can tell you is the mass, period, and a brief sniff of the atmosphere (if you subtract the star spectra before a transit from the spectra during a transit, you get a vague idea of the atmosphere composition).

Alas I have not gotten my patch yet. I'm hoping to score a TESS patch and a CHANDRA patch, cause that's' another one of our missions.
