Is there anything faster than the speed of light?

If not, then how is the universe expanding at a faster rate than the speed of light?

Two things traveling the opposite direction of each other can effectively become farther apart faster than the speed of light.

The lightspeed limit is only relative to the photon itself you cuckface.

General relativity imposes no speed limit on the expansion of space itself. Space is not a thing in the universe.

huh

What he said is actually half bullshit; each of the two observers would observe the other traveling at subluminal speeds.

The universe doesn’t expand at a particular speed, it expands at a speed per distance. Right now it’s about 70 kilometers per second per megaparsec.

Anyway, modern scientific paradigm states space / time isomorphism of the laws of Nature.
This implies that these laws are somehow enforced throughout the whole Universe at infinitely high speed.

>observers
Literally anything that isn't an observer can travel at a relative velocity that exceeds the speed of light.

The answer is that actual velocity is limited to the speed of light, not apparent velocity.

Tachyons, per definition, are faster than the speed of light.

Now, finding one is a different matter.

>Tachyons, per definition, are faster than the speed of light.

They also don't exist.

>Is there anything faster than the speed of light?

Yes, the speed of shitposting on this board.

Light isn't arbitrarily set as the "speed" barrier.
It's the math.
Light is light for reason.

>A photon is an elementary particle, the quantum of all forms of electromagnetic radiation, including light. It is the force carrier for the electromagnetic force, even when static via virtual photons.
[Wikipedia]

Basically it's radiation itself in particle form.
Nothing mathematically can move faster because of the physical characteristics of photons themselves:

The photon has zero rest mass and as a result...

...Like all elementary particles, photons are currently best explained by quantum mechanics but exhibit wave–particle duality, exhibiting properties of both waves and particles...

...The photon's wave and quanta qualities, are two observable aspects of a single phenomenon, and cannot have their true nature described in terms of any mechanical model,[2] thus a representation of this dual property of light, which assumes certain points on the wavefront to be the seat of the energy, is also impossible.

no.... definitely no

Thanks for copying and pasting a ton of wiki that you don't understand. It really contributed.

How do you know?

The light speed places an upper limit to the speed of information transference. The expansion of the space doesn't transfer any information whence its speed can be greater than that of light.

this
how do you know they exist? It just an abstract theoretical construct
> imaginary mass
> v>c

if there is you cant see\interact with it my senpai because its 'timespeed' relative to you is a complex number .

basically we have no idea if anything does go faster then light or how to check if anything does . just that nothing has ever been observed\proven to go faster then light .

So lemme get this straight,
It's not planets themselves moving outward from an epicenter but rather space in and of itself is actually expanding and dragging 'attached' matter with it and so it can move faster than light since it isn't actually moving it?

Expansionist have always stumped me when it comes to space expanding...

a) Are we creating space, i.e. Planck length splitting everytime space expanded.
or
b) Is the Planck length stretching with time.

I want to say a) because the Universe came from Planck scale fluctuation.

Anyone know the answer?

Kind of. Except it's also not "moving faster than light." Any given point can be considered to be stationary.

Two cars are back to back and speed away from each other, each traveling a relative speed of 50mph.

Each car sees the other car moving away from it at 100mph.
People outside the cars see both cars are moving 50mph.

Because space itself is expanding, so it's in the same place but the place itself is expanding and rapidly too. Right?

>Because space itself is expanding,
/thread
The basic issue here is that information/change cannot propagate faster than c.
Distant galaxies moving away faster than c is fine because we're not pushing them.
They become more distant, but not as a result of anything we're doing.

The non-action, between the expanding galaxies, is faster than light.

jesus christ literally watch any science show on space theres like 10 of them all great

neil degrasse, morgan freeman, steven hawking all says this in like the first 5 seconds of every show

picture two baloons, which represent galaxies

then put the baloons on a water and make a wave in the middle

the wave of water is space, and it puches the two baloons apart

eventually the two baloons can be pushed away from each other faster than light can travel between them

christ its not hard

The wave is faster than the speed of light.

There are a few exceptions to universal speed limit.
1. Space itself can move faster than light.
2. The quantum information in an entangled pair of particles travels faster than light, perhaps instantaneously. This was proven to be true via Bell's famous inequalities. However, no information can be transmitted by the entangled pair, because the particles randomly determine the outcome of the measurement.
