Time might not be quite what you think it is, but that's just Relativity 101. We're still never getting rid of the concept of time. In what sense it could fail to be "real"?

>>11508523
why not both?

the way we understand the universe is unique to our mind

>>11508700
humanity confirmed for speshul snoflakes

>>11508523
Invention.

Things can be animated or be still. That's it.

Time and space are just the exact same thing

General Relativity:
You expand space and time accelerate
You compress space and time slows down
We can see this happening right now as Satellites do not share the same time frame as the people on Earth and Astronauts age slower than us.
Satelltes have to constantly adjust their time or else they would have errors in calculating distances

Heck, we can even use just a philosophical thought
You define "time" as the arrow on the clock
Or the Earth around the Sun
Sun around the Milky Way
Milky Way on the Local Galactic Group, Virgo supercluster, Local Super Cluster, Laniakea, and Observable Universe

Time and space are not just the same thing.
They also do NOT exist
They are all but an illusion brought about by the constant movement of the cosmos

Hence:
Time
>a movement that stays in constant position at constant speed
Space
>area from which movement can or already taking place

Depending where a lifeform is born and how long their lifetime is determines whether time exists for them or not. Because of entropy and the motion of the celestial bodies it would seem likely for time to be a concept for most lifeforms in the universe.

>they don't exist because they are emergent from more fundamental interactions
this is the most brainlet take possible

is a wave not real? then how come it splashed your face

Time is an invented interpretation of existing physical reality.

>>11508828
invented implies someone made it consciously, it's more of an intuitive interpretation that comes from our instincts and evolutionary biases

>>11508533
Sped go brrrr....

>>11508523
Length is a human invention that measures space in meters.
Mass is a human invention that measures inertia in grams.
Time is a human invention that measures entropy in seconds.

Wtf is so complicated and mysterious about this. It changes nothing whether we invented it or not.

>>11508523
Time is change.

time is a measure and measures are observations and thus inventions of the mind.

the thing time is measuring is concrete however, being motion.

if you boil it down to motion = time, then time is real and not an invention.

expiration may not be real, however.

>>11508523
redarteerd psued!
Is cowffee good for you?

>>11508824
Yes.
Wave is not real
It's just water that is in motion

>>11509863
but you just said that waves are real, because the word wave refers to water in motion in that particular way

>>11509897
You get the idea
Waves, whirpools, waterfalls, rain, etc
They are all just water in motion

Same applies to time and space

>>11509925
but waves are still real, just like time and space are still real, sure they may be things that emerge from more fundamental properties, but that neither makes then not real nor do we even have a firm grasp of what the lowest fundamental that everything is based on is in the first place

>>11510575
It's just a different angle for the same object, mate
A lumber is different from a chair but they are both wood
Now, if you say that a match stick remains the same after burning it, then that would be wrong.

You know, Physical change vs Chemical Change that we learned in 2'nd grade.

You don't even need to deal with quantumn stuff to figure out that Time and Space are just the same once you questioned how they were defined in the first place

Is time based on the speed of the ticking of the clock? The speed of your nervous system to reach the brain? The rate at which your cells die? The frequency of electric transition of the photons in the ultraviolet wavelength?

See where I'm coming from? The fact that time needs a reference proves that it is not just dependent on definition. It also does not exist. It's just an illusion of motion

Same goes for Space which is just the area from which the motion happens

Einstein just made things more complicated by saying and proving that the fabric of time and space can be manipulated through gravity

>>11510668
you're saying that chairs don't exist because it's made out of the same thing as lumber is

i am currently sitting on a chair that exists

the same goes for time, it clearly exists

you are an idiot

>>11510678
Is it really that difficult to admit that "chair" is another word for modified lumber?
Steam is just evaporated water
Ice is solid water
Mud is wet soil.
You're a talking shit

>>11510681
it's irrelevant, the word being modified doesn't mean chairs don't exist you fucking brainlet

chairs exist, steam exists, ice exists, mud exists, and time exists

>>11510705
Not until you questioned its definition and arrive at its most simplest definition

>>11510713
look anon, the word time refers to an observable phenomenon, whether that phenomenon is a fundamental interaction or an emergent one changes nothing, it still exists and arguing otherwise is pointless

>>11510748
No.
It refers to a rate that we believe is happening in constant speed

Your reaction is exact reason why Einstein was so controversial. The entire point of General Relativity is to show that that rate is completely dependent based on how much gravity the given object is experiencing

At high gravity you would believe that nothing is happening but once viewed by a person in lower gravity, they would see that you are aging slower because of time dilation.

Time and space and space are the same illusion brought about by different definition.

As such, travelling faster than light would also send you back to the past

>>11510770
my reaction has nothing to do with time, it has everything to do with a mongoloid who doesn't know how language works because he's autistic

>>11510770
i thoughts when sth is faster then light it just loses its information

>>11510838
Going faster than light would break causality, anon.
You would literally break through time and arrive to the past

>>11508523
>is time real
Yes

time is a measure of the expansion of the universe

>>11510847
i read an article. it is possible but you just lose the information. the did it with some kind of particles, i think photons.really

>>11510847

Time is real. Entropy is the arrow.

You should be asking this about mental illness.

The DSM criteria are a social construct claiming that almost every emotional response and psychological defense and coping mechanism anyone might display at any time isn't supposed to happen, and must be medicated with mystery drugs invented within the last 30 years or so.

It's propagandized relentlessly in all media and people make billions of dollars from it.

Soon it will be used as justification to medicate everyone to "prevent" isolation-induced psychosis, now that everyone is ordered to be isolated.

The whole point of the pandemic is to normalize mandatory psychiatric treatment for everyone, and the idea that the world is now run by doctors.

It would be WW3, if anyone had a means of fighting back.

>In the following examples, certain influences may appear to travel faster than light, but they do not convey energy or information faster than light, so they do not violate special relativity.
i.e Shadows and Universal expansion

ehhh... This is pretty much as no different from trying to measure absence. Technically correct but come on. You're just bullshitting me here

These are not mutually exclusive.
