By your stupid and nonsense logic , one can not say that dark matter exists, because it's existance has not been verified. (It is simply implied )
I challenge you to have a conversation with a flat earther , you will note that he would use the same kind of logic that you are using .
Your ignorance speak of creationist indoctrination, and your lack of education.
Ask yourself, this question:
What is “evidence”?
In science, evidence is something that can -
- either be detected (or observed)
- or be measured
- or be quantified
- or be tested
Or
- it could be any combination of the above
- or even more ideally, all of the above.
For science, it is best that you can do “all of the above”, but that’s not going to always going to happen.
You have mentioned dark matter, not me. But let’s go with your example.
While it is true, that dark matter cannot be observed or detected, it just mean electromagnetically detected, which mean you cannot detect with any instrument that use wavelength, eg optical (light), x-ray, gamma, near infrared, etc.
But dark matter does have effect on matters (galaxies, stars, quasars, etc), through gravity. So the effect of gravity can be measured.
Since astrophysics isn’t your strong point, I don’t think you would understand my explanation, so let me give you another example.
Here is a scenario, you see an exposed wire or cable. You cannot see with your own eyes if there are electricity coursing through that wire. And if there is electricity, you won’t see it, but the effect are real. Touch it, and you will electrocute yourself; the electricity will pass through you, down to the ground. The effects will pain, convulsions and burns.
That’s evidence of what you cannot see (electricity), but does have effect, thus electrocution.
Do you see the parallel here, leroy?
Like electricity, dark matters cannot be observed, but it does have effect upon stars and galaxies, just as electricity will have effect on you if you touch it.
Going back to the electricity example, although you cannot observe or see electricity, you can detect and measure electricity, using instrument or device that can measure the electricity current, voltage and power.
Now the parallel with dark matter is this:
If you ever studied physics whatsoever, you would have learned that gravity is related to masses of matters. It doesn’t matter if these matters are ordinary matters or dark matters, they all have measurable mass, therefore gravitational fields and forces exist.
Ordinary matters have mass, therefore it has gravitational fields. And so does dark matters.
Space observatories, like NASA’s WMAP and ESA’s Planck spaceprobe, have measure the mass of the observable universe, and discovered that the masses of all ordinary matters don’t equal to the total mass of observable universe, so where does all that extra masses and gravitational forces come from?
The other masses come from dark matter (and from dark energy). Both of these space probes/telescopes have provided tremendous amount of data and evidences, but for you to deny to be any evidence at all, only make you a complete fool.
If you think know more about the universe, then NASA, ESA (European Space Agency), and all other astrophysicists and astronomers, then why don’t you write your own hypothesis that dark matter and dark energy don’t exist with testable data and evidences, since you think you are smarter than everyone else?
