3 Things 'Faster Than Light'

These 3 things go "faster" than the speed of light. How's that even possible?
↓Want more info?↓

More about the experiment:

Advanced scientific note about Doppler: If there is a light moving away from you at constant velocity in static flat (Minkowski) space-time, no matter how red it is, you will never conclude it is going faster than light. But, here I am discussing the conclusions one might come to if you mistakenly use Doppler in the context of the curved space-time of the universe (where there is expansion). Interpreting the huge redshift as a result of the doppler effect, could make one think that galaxies we see are moving away at speeds approaching light speed. And since what we are actually seeing is light from those galaxies from billions of years ago, and given that the universe is expanding, you might be tempted to say that they have since "accelerated" to faster than the speed of light. You might go further and say that there are more distant galaxies that we can't see which are moving away even faster. So you might conclude there are galaxies moving faster than light in the universe. But the redshift isn't from doppler and this "acceleration" of the expanding universe isn't actually causing a true increase in velocity.

Sometimes astronomers do say there is a faster than light "recession speed" by pretending the expansion of the universe is causing distant galaxies to move away from each other at a corresponding velocity, but that's misleading. In general relativity, you can actually have an increase in space between objects without causing a corresponding increase in the relatives velocities of those objects.

Summer is faster than light
And school is the slowest thing ever

Edit:OMG 800 LIKES I NEVER CHECKED THIS COMMENT BUT THX SO MUCH FOR THE LIKES

Second Edit, 2 years later: I am very much sorry for making the first edit and now I am matured as human.
Again I am very sorry for the edit and this will be my last edit, goodbye.

The laser can't move faster than light, it is light.

[debblez]

Ok just clicked on the video, and I am insanely curious how a squirrel with scissors is faster than the speed of light

[youexpectedausernamebutitw]

I can make something faster than light.
1.Record an open flash light
2. Fast forward the video
Ez pz lemon squeezy

Well, that laser thing is tricky. We tend to imagine light (and lasers) as continuous beams, but, when you turn on a laser, you are actually shooting photons. When you swift the laser so that it "moves" across the surface of the moon, you're just changing the origin of the photons you're shooting. Imagine it as if you were shooting a gun. Bullet hits do not move, as doesn't the "laser dot" seen from earth.

'Faster than *Light*'
Me, when my battery reaches 1%

[csanad]

Light: im the fastest thing ever
Weekend: hold my beer

[devilboy]

The time it takes for a girl to reject me is faster than the speed of light.

[cactusavian]

What is faster than light?!





Lighter.

[riasmywaifu]

If nothing is faster than light, how darkness gets there first?

You forgot one thing that does move faster than the speed of light. It's been proven multiple times and has all scientists baffled: Rumor in a small town.

[Avery-dfvy]

All of them
1. The Weekend
2.Sonic the Hedgehog
3.Me after 3 cups of coffee.
Pretty sure these are right.

"The cut is a few times faster than the speed of light"

Chefs: *the problem being faster than the speed of light is you can only live in darkness*

[theduck]

Teacher: What's faster than light Pete?
Pete: Diarrhea.
Teacher: Pete i didn't teach you this, it's light. Explain why it's diarrhea then, if you think that's fast.😏
Pete: Well.... i had diarrhea once and i had to run to the restroom, and i crapped my pants before i could turn on the lights in the restroom...
Teacher: PETE!!!!

You forgot me when my mum gets back and I haven't done the jobs I was supposed to do.

[martonlerant]

Good job!
Managed to show zero valid examples!

[charles]

it is the place that the photons land that go across the surface of the moon that go faster than if a photon go to one side of the moon to the other but the photons from the laser still just go the speed of light

[lumps]

Moving a laser acrossed the moon is like shooting a minigun acrossed the moon, the laser itself isn't moving, it's shooting out photons which strike the surface of the moon at different points, actually, it's like saying if you fling a paintbrush and the paint lands on two places faster than light could move, then it was faster than light.

[azpet]

The speed of idiots being born is faster




EDIT: lmao, people really think i am being serious
