The Lord is Subtle but he is not malicious.
I have second thoughts. Maybe God is malicious.
Look at the blue galaxies in this photo. Astronomers conclude the 33 of the blue galaxies are only 11 galaxies that are producing an optical illusion created by gravitation lensing (as predicted by Einstein’s general theory of relativity).
Image : This gravitational lens shows a strange blue objects stretched. They are spread in a circle in this picture, but are only multiple views of a single ring galaxy.
The analysis showed that at least 33 images of 11 different background galaxies are discernible in this image.
Predicted by general relativity by Albert Einstein, a number of gravitational lensing have been observed by Hubble. Sometimes, when the alignment between two objects is perfect, the image of the distant object can take the form of a ring of light surrounding the subject at hand.
In case of perfect alignment between the observed source (a star for example), and another stellar object (a black hole for example), the black hole in front will act as a gravitational lens or deflector.
The observer will not see the star as such but rather as a ring, this ring is appointed, the Einstein ring.
A star, although a mass much lower than that of a galaxy, can also act as a gravitational lens.
The effect is obviously much less powerful, it is called, micro gravitational lens.
and how about this one:
At first glance, it seems that many are strangely elongated galaxies around the five brightest quasars, in white on the image. In fact, a cluster of galaxies acts as a gigantic gravitational lens that distorts and multiplies the luminous objects located behind. The five white points of light near the center of the cluster are in fact images of the same distant quasar.
When a scientist gave a talk about this phenomenon in cosmology class, my stomach turned, I thought to myself, “then what the heck can we ever believe about our observations.”
We presume the phenomenon isn’t wide spread because we don’t suppose there are that many gravitational lenses such as the one pictured above. Theory doesn’t predict that they are ubiquitous, but then again, our theories may be based on flawed observations to begin with! Like someone on Vodka, they might be seeing things, except this time we see multiple images of things while sober!
[the Vodka designation means the following material likely has errors but has data that are worth considering]
One amateur (whom I probably would disagree with 80% of the time) suggested the universe could be deceptive. He suggests the deception is ubiquitous. Let me say I don’t yet agree because theory doesn’t predict that we’ll have so many deceptive images as the one depicted above, and that such examples are rare. But do we really know? It may be worth considering. I’m not endorsing this website because I think there are most definitely some basic physics errors, but I’m indebted to Jerrold Thacker for at least getting me to think and for his kind reply to my queries. His website is here:
Please don’t base your physics understanding on this website. For example, his treatment of the Shapiro effect may be faulty…but it will get you to think about what you really believe.

It’s possible that the entire universe is a lie of sorts.
That was the inspiration for this discussion.
