Gravity distorts space, the "ray" travels through space in a straight line, it's space that bends.

The approach taken by superstring theorists is to add variables to represent motion in additional spatial dimensions. So while they cannot visualize in ten dimensions, by extension they can still calculate the behavior of particles moving in that many dimensions.
The problem is to avoid topological defects such as magnetic monopoles (particles that emit a magnetic field at rest). This is an amusing point in relativity theory: we know that a charged particle in motion curves under the influence of a magnetic field. But what if we shift to a reference frame that moves along with the particle. If the particle is at rest in that frame, there is no velocity, and so no force exerted by the field. The answer is that the fields themselves are also altered by the change of reference frame: in the particle's rest frame, there is an electric field that cause it to accelerate.
Similar things happen in General Relativity. One of the side effects in rolling up higher-dimensional spaces (to produce our three-dimensional reality) is that magnetic field lines can be forced into spatial rifts, which then appear as magnetic monopoles. A brilliant Indian mathematician "proved" (I'm not sure anybody understands the proof) that avoiding magnetic monopoles requires that the universe sit in ten or eleven spatial dimensions.
That current theory opts for the "ten" option may have something to do with the seven seals in the Book of Revelation. I'm not aware of any theoretical reason for the choosing ten over eleven. Much as Gell-Mann named his model of particle zoology the "eight-fold way" as a reference to Buddhism, my paranoid brain is half-convinced that some theorist chose ten because at the "end of days" that would mean the seven "sealed" dimensions would open upon our return to the Godhead - matching the number of seals on the scroll opened by the lamb.

Actually, I will argue a Lizard Brain was created for these things.
The human mind was created with an additional ability to recognize ever increasing complex patterns.
Plus the ability to use pattern compression (like a cross between fractal and zip compression), and once again, re-iterate the pattern recognition process.
Mix in a little bit of curiosity, and a few free cycles to notice the world at varying levels. And we eventually stumble across communications and science. Communication only works because the definition of things like CUP is relatively fixed and contextually determinant (Sports vs. drinking).
So. I argue that we are designed to SEE patterns. Including ones that we do not yet understand (Gravity), and then we find ways to study them (lasers?) until we can produce devices that manipulate what we see. Once we are there, our endless creativity at trying different things (testing conjectures) until voila, we find something (spinning magnets<scifi guess="">) that appear to manipulate the gravity we see via lasers... Until we get a unique result.
Wash, rinse, repeat.
So, it is REALLY hard to explain a 4th or 5th dimension to someone who truly only sees 3 dimensions. But I will argue it becomes easier to mathematically accept an n-th dimension when we know how to manipulate it to get a non-linear result in 3D space.
Meaning. We will get there! And given a billion years of evolution, testing, recording, I would only take the counter bet because I would not live long enough to pay the winner!

Those are definitely good points, but here comes the turtle.
Spacetime has been confused, widely, because of the terms of "sheet" for spacetime. Although the analogy is good, simple and easier to imagine. The problem comes, when you are trying to depict how gravity works; straight-line in which direction, how much space bends, how is it that a space is always bent towards the centre? These are a few problems that arise in minds when we consider spacetime to be a sheet.
I don't believe in dark matter, dark every and stuff similar to that. What I believe and can theorize is that "spacetime" is just the medium for "electromagnetic waves". We were lied when we were told, "light travels in vacuum". Physics books should be updated to include accurate descriptions over simplicit wrong explanations. Accordingly, the dark matter is nothing, but just another "level" of electromagnetic spectrum, which we have not yet discovered or come up against. We know Gammas are the strongest (in the means of their energy), who knows of the other way around?
This is where Quantum jumps in and breaks the very simple common sense. They take us in worlds, where we cannot go, and try to explain our worldly problems in an inter-universal solution format. For example, instead of explaining Big bang, they are finding answers to Multiverse, instead of creating equipment sensitive enough to focus on a single electron particle, they are calling it a wave. What a lame excuse; same as the one programmers make by saying, "It works on my machine!".
Physics, needs abnormal people, who are able to imagine the world in an unusual way. Normal people are just making it worse.
Or... am I missing the joke symbol here?

What these people don't seem to realise is that if there's all this "dark" stuff distorting everything, then everything they're seeing through telescopes is distorted and wrong, therefore all their assumptions based on that information are wrong, therefore there's no "dark" anything.

The truth is this:
Fall of the angel of light resulted in the fall of light speed. The slowing light generated massive red shift. And was now moving slower to be affected by gravity.
Dark matter/dark energy was an entity invented to make the naturalistic explanation fit. Occam's razor would removd it.

Oh they realise it, alright.
I bet they all regret coining the phrase 'dark matter' and 'dark energy'
Either *something* is out there (and in here!) or Einstein was wrong. Could well be the latter (after all, Newton was) in which case DM and DE are just letters in an equation.
But don't be fooled into thinking that they are actually Matter or Energy

That's the joy of astronomy: You can spout any old bollocks, and no-one will live long enough to prove that you're wrong.
How is it that they can tell us about the entire construction of stellar systems and the universe, and all the dynamics of supernovae, just by looking at microscopically tiny blobs of light (or radio data), but we have to send ships to the Moon, Mars, Saturn, etc?

Well (as I'm sure you know) what actually happens is someone formulates a theory and observations support it or otherwise.

For Example, the regular dimming of a star's light together with evidence of a perceived 'wobble' (detected by changing dopler shift) could be caused by something other than a planet orbiting - but these are real, repeatable measurements and the theory fits.
Similarly with supernovae - there's a theory, the maths holds together and observations support the theory. sure, they could be caused by aliens' wars, time travelling weebles or bad spaceship drivers - but there's little reason to discount the theory until either a better theory comes along, or observations show the theory to be wrong.

Indeed, but what troubles me is that the observations are of such tiny amounts of light/radio waves, that have traveled God knows how far and through God knows what (e.g. if it travels through a tiny patch of blue dust, in the billions of miles between here and its source, it becomes more yellow), so grand assumptions simply cannot be made.
But grand observations are made, nonetheless, and compounded with further grand assumptions, then backed up with numbers that are tailored to fit, until we have a model of the universe that makes very little sense, and is constantly being challenged by observations that are "more accurate" because they are backed up by three photons more than the previous observations.
And nowhere along the way does anyone admit that it's all guesswork -- they call it "great, new discoveries", rather than admit it's all guesses.
We need more data, not more guesses. Guessing is easy, but getting it right requires more than 2000 photons per month.

But so would a thousand simpler theories -- i.e. plain ol' boring dust or temperature gradients could far more easily be proven to be the cause of wibbles.
But that wouldn't make people famous or get them big research grants, would it?
And when a few more quanta of the EMS arrive, which should easily prove that something else is the case, they'll just "massage" their Grand Unprovable Theories to make them fit the new data.

Quote: tiny amounts of light
The Hubble Ultra-Deep Field Image, a study of galaxies as old as 13.5 billion years at distances up to 60,000 light years was a composite of 288 exposures of approximately 20 minutes. Many degrees of magnitude more than 2000 photons collected in considerably less than a month I would suggest!
I am not a number. I am a ... no, wait!

But that's not what we're talking about.
We're talking about the (was it five or six?) novae at Extreme ranges that were used to cobble together the ridiculous "dark energy" theory.
60,000 light years is just down the road.

IMO, Physics needs people who can see the bleeding obvious without getting bogged down by ideas that sort-of work but don't.
