Bullet cluster could only be explained by the hypothesis of dank matter by the incompetent theoretical physicists, and thats pretty much the only meme they have when it comes to the subject of dank matter.
Learn what evidence means.
Are dark matter and dark energy just buzzwords for we don't know?

Do you know what the Bullet Cluster is? In short, we can map out the location of the matter by gravitational lensing. We can then count the stars, and count the dust, and such.

The gravity is not coming from between the galaxies where we expect the stardust to be. It's coming from the galaxies themselves, showing little to no trace of collision, in spite of the fact that we can see that the matter has been displaced by the collision.
You have to be pretty crazy to suggest a modified theory of gravity where gravity comes from where the matter would be if it didn't collide.
Currently, the only sane option available is there is some additional matter that does not collide with itself (or only does so weakly), aka dark matter.
PS: Not just the bullet cluster. We have other galaxy collisions. There's also other lines of evidence, such as from the cosmic microwave background radiation.

Is this what you resort from "There's pretty solid evidence" ?

Dark matter:
Total mass of our universe = 27%
Observable mass = 4%
4 + x = 27
x = 23
x = dark matter
Dark, as in doesn’t interact with light.
Matter, as in comprised of matter.
Dark energy:
The curvature of the universe has been measured to be flat, as confirmed by the cosmic microwave background.
The total gravitational energy of our universe has been measured to be 0.27.
This would indicate open curvature, as a flat universe would be omega = 1.
Therefore, there must be something else contributing to the total gravitational energy of our universe.
Empty space is actually a bubbling – boiling – brew of virtual particles and fields popping in and out of existence.
Empty space has energy.
As we know the curvature of the universe is flat, that the gravitational energy measured against its mass is 0.27 and that empty space has energy, therefore the missing 0.73 must be coming from the energy of empty space.
Et = 0 / omega = 1
0.27 + x = 1
x = 0.73
x = dark energy
Dark as in, unobservable directly
Energy, as in it is fucking energy.

Are you honestly saying that the entire thing is based on our inability to observe that mass with our puny technological capabilities ?

No, you have completely misunderstood.
It is based on the indirect observation of mass that doesn't interact with light.
Dark energy has also been indirectly observed.
These are experimentally verified phenomena.
I'm not quite sure why they are so misunderstood, however perhaps it's the spooky names.

I'm very sceptical about the accuracy of this measurement and the tons of things they could have missed when doing it.
> Dark energy has also been indirectly observed.
how so ?

How did they measure it, user?
And what could they have missed?
>how so ?
Why don't you tell me, user.
You seem to have a good understanding of cosmology.
Jayden Kelly
Well if you didn't understand shit you could have just said so. you didn't have to recite the shit you don't understand as if you knew them very well and could verify their legitimacy.
Carson Hill
I can explain if you would like, it's just that you seem to be doubting the legitimacy of something that you clearly don't understand.

>I don't know shit
And then I shall tell you everything I know about dark matter and dark energy.
