If we (aliens) have already harnessed gravity then it’s realistic that they can’t measure the universe based off the Big Bang symmetry.

Also the scientists just proved that when photons hit an extreme magnetic field that they turn into gravity and vise versa. Using the new telescope that’s been taking pics.

So basically they will have to recalculate the entire universe based on this concept that light and gravity are interchangeable through magnetic fields.

Based off these two observations, we conclude that there is more mass we cannot see.
Are you under the belief that anything that interacts strongly with gravity also must interact strongly with light? Is there some reason that one can't exist without the other?

Lensing doesn't work like that. Objects very close to the observer have less impact on lensing. The optimal distance is about half way to the source. It's just geometry.

Nope. Only a few very nearby giant stars can be resolved by Hubble and JWST (Betelgeuse, Vega), all other stars are completely unresolved (>99.99%). But these telescopes can easily remove distant galaxies, because they have a larger angular size.

Galaxies are not opaque. You could see the background one through the foreground one. You would see two sets of emission lines in the spectrum, as is commonly seen in lensed galaxies.
Furthermore, if the foreground one was big enough it would lens the background galaxy around it. Not just the background source but the background lens too.

You would only expect them to be concentric if you had one smooth symmetric mass profile. But a galaxy cluster is more than just one big halo, there are hundreds of galaxies inside which can all effect particular objects. The clusters like that are particularly complicated because it is two clusters in the process of merging. Complex clusters are better targets for lensing. There are models of the lensing.
Yes it is definitely lensing. As demonstrated by the reoccurring supernova refsdal, one supernova was seen multipley imaged in a cluster, it appeared simultaneously in 4 places. The lensing models then predicted (successfully) that another image of the same supernova would reappear several months later on the other side. They predicted the location and timing.

He was confused about me repeating the phrase "empty space" and insisted there was a star in the way, somehow behind another star, in empty space.
I chose to explain that the angular size of distant galaxies is smaller than that of nearby stars, so there is no possibility of stars being in the way if we're observing the distant galaxies, otherwise the galaxies would be occluded.

The basic concept of things can block line of sight of other things is expected to be common knowledge, so I just assumed he was having an issue with distance and size. After all, galaxies are bigger than stars but farther away.

People considered that, such objects were known as MACHOs. Even without a light source those objects would occasionally pass in front of background stars, lensing them. The shear number needed to explain dark matter would make these events fairly regular. In the early 90s huge observational campaigns were undertaken over years to find these events, monitoring millions of stars. They did find microlensing events, but only of currently known populations of stars. The result was that there dark matter as planets/low mass stars/black holes/white dwarfs was ruled out over a huge range in mass. Furthermore this idea was further shot down, as both the CMB and big bang nucleosynthesis say that dark matter cannot simply be normal matter.
Maybe you should read the history before assuming everyone else is just retarded.

Of course not. You need better equipment to actually observe black holes.

No, but you can place an upper limit on their abundance. Just like the microlensing experiments haven't concluded there are no rogue planets, there just aren't anywhere near enough to make a significant contribution to dark matter. Rejecting the hypothesis is much easier than looking for black holes, because you know exactly how many there needs to be.
>Instead of basing my views on the usage of a single observatory
You didn't even open those papers then. From multiple programs done with many telescopes, finding consistent results. Some of those programs are still running, collecting more data which further supports the conclusion.

Using a ground telescope to search for rogue planets through gravitional lensing is like using a spoon to dig up a coin hidden somewhere in your backyard.
You do realize that we can use the same retoric on all the black matter detection attempts made so far, right? "We've used our most advanced techniques and didn't find anything, so it can't exist".

Just because we found out eventually that it was wrong, doesn't mean scientists are retards for thinking of it as a good possibility at the time.
We once thought our galaxy was the entire universe and now we know it isn't.
We once thought the universe was eternal and now we know it isn't.
We once thought the universe's expansion was slowing down, and now we know it isn't.
Having more accurate knowledge of the universe now doesn't mean scientists were retards back then, it just means they had access to less information. This is how science works, anon. We don't need to abandon relativity as long as it works, and relativity is once of the most successful theories we've ever had.
If we find a better theory, we should swap to that, but saying "there's totally a better theory" when the current one works fine most of the time, and then not actually making a better theory that explains more than our current one, is not scientific.

On your baseless opinion. Which doesn't matter to the experiment, they are only testing if DM is rogue planets. If there is no DM then the hypothesis is false. How is it that you claim DM doesn't exist, and yet you are still trying to defend rogue planets being DM? It's completely illogical.
>Only if our current theoretical framework is perfect as is. And considering it currently requires a magical (in the literal sense of the word) concept to continue working, I have my doubts that it is.
If dark matter is simply rogue planets then everything is fine. You are rejecting a hypothesis under it's own assumptions.
>The MACHO project used primarily a singular ground telescope.
There is more than one project, and they use multiple telescopes for followup, including space telescopes. EROS, MOA, OGLE, KMTNet, PRIME. And events have been found in Gaia and ZFT data.
>I can keep looking at the sky, but no matter how many times I look, I will never see a black hole.
Back to this straw man argument. They do see microlensing events, even from rogue planets and black holes. So clearly the technique works, but there aren't nearly enough to explain DM.
>You do realize that we can use the same retoric on all the black matter detection attempts made so far, right? "We've used our most advanced techniques and didn't find anything, so it can't exist".
No, what you do is you place an upper limit set by the sensitivity of the experiment. In the case of DM candidates, you rule out particles above some interaction cross section over the range of mass. The same applies for microlensing, these experiments have a mass range and an upper limit on the rate of lensing events. In the case of lensing the cross section is set by GR, and so the upper implies an upper limit on the density. Therefore one can reject the hypothesis that rogue planets make up a significant fraction of DM.

If you speculate that a form of matter must exist which properties make it undetectable, you've started talking about faith rather than science.
>and yet you are still trying to defend rogue planets being DM?
Is it really that hard to keep your emotions out of this? I've said that I'd sooner believe that rogue planetoids are behind the observed gravitational deviation rather than believing that magic is behind it.
Please actually read what I say rather than react to what you believe I said.
>If dark matter is simply rogue planets then everything is fine.
It's not, because that means that there is suddenly a very large increase in mass distributed all over the universe. It doesn't take a genius to figure out that this would have a profound effect on how we believe the universe came to be.
>There is more than one project
So far, there has been only a single large-scale project which searched for rogue planets using technologies that were close to a century old.
All other projects have been much, much smaller in scale and have been using technologies built almost half a century ago.
Which you would know, if you'd read your own sources.
If I look at the sky and see no black holes, will I suddenly start seeing them 50 years later while wearing sunglasses?
>Therefore one can reject the hypothesis that rogue planets make up a significant fraction of DM.
Do you not see the hypocrisy in your own statement?
When will you accept that dark matter doesn't exist, considering that every single experiment so far has shown it to not exist?

Logic is not an emotion. If you cannot make a logically consistent argument then clearly your argument is bullshit. You also constantly regurgitate the same arguments that have already been addressed (black holes, black holes, black holes..). As if you want the discussion to run in circles. I'm just going to ignore these.

We're talking about things that would invalidate the microlensing constraint, this is not one of them. And existing models already include dark matter.
>All other projects have been much, much smaller in scale and have been using technologies built almost half a century ago.
Bullshit. OGLE, MOA, KMTNet are all bigger than MACHO and they are all still running. OGLE has 3 decades of data. All of them use modern purpose-built telescopes.

That's not faith, that's logic. Faith would be making an absolute statement not based on evidence, such as claiming to know DM does or does not exist. Failed direct detection experiments put upper limits on the parameter space, several particle candidates have been ruled out already. But there more which have not. Without a direct detection it will remain the standard model unless cosmological tests show significant deviations from models like CDM, or until there is a serious alternative model which can explain away the observations without dark matter. The latter is not simple, people have been trying for even longer than they've been looking for DM.
