technically wrong on one point,
(Space expanding faster than the speed of light)
Overall premise that "The Alien Hypothesis"
has too many laws of nature to overcome
and is therefore a "overcoming the laws of physic" problem
and nor simply "a technological problem" still stands.
Let me explain.
Why doesn’t the expanding Universe break the speed of light?
"Just 13.8 billion years after the hot Big Bang,
we can see objects up to
46.1 billion light-years away.
No, this doesn’t violate relativity."
What “nothing can travel faster than the speed of light” actually means
"It is true: nothing can travel faster than the speed of light. But what does that actually mean? Most people, when they hear it, think the following thoughts.
"When I observe an object, I can track its motion, observing how its position changes over time.
When I see it, I can record its observed position and the time at which I observe it.
Then, by using the definition of velocity — that it’s a change in distance divided by a change in time — I can get its velocity.
And therefore, whether looking at a massive or massless object, I had better observe that the velocity I get never exceeds the speed of light, or that would violate the laws of relativity.
This is true in most of our common experience, but it isn’t true universally. In particular, all of this includes an assumption that we pretty much never think about, much less state. The assumption in question?"
"That space is flat, uncurved, and unchanging. This occurs in Euclidean space: the type of space we normally conceive of when we think about our three-dimensional Universe. Most of us envision doing something like putting down a three-dimensional “grid” on top of everything we see, and then try and describe positions and times with a set of four coordinates, one for each of the x, y, z, and time dimensions."
"In other words, most of us understand the basic concept of special relativity — the “nothing can move faster than light” part — but fail to appreciate that the real Universe cannot accurately be described by special relativity alone. Instead, we need to take into account that the Universe has a dynamical fabric of spacetime underpinning it, and that it’s only the motion of objects through that spacetime that obey those laws of special relativity."
(So that part I nailed 100%.)
"Instead, we have to recognize that our Universe obeys the rules of Einstein’s general relativity, and that those rules dictate how spacetime evolves. In particular:
space itself can either expand or contract,
space itself can be either positively or negatively curved, not only flat,
and that the laws of relativity apply to objects
as they move through space, not to space itself.
In other words, when we say “nothing can move faster than light” we mean “nothing can move faster than light through space,” but that the motion of objects through space tells us nothing about how space itself will evolve. Alternatively, we can only assert that nothing moves faster than light relative to another object at the same location, or event, in spacetime."
"Space doesn’t expand at a speed
So, nothing can move faster than light through space, but what about the ways that space itself changes? You’ve likely heard that we live in an expanding Universe, and that we’ve measured the rate at which the fabric of space itself expands: the Hubble constant. We’ve even measured that rate precisely well, and can be certain, from all the measurements and observations we’ve taken,
that the present-day rate of expansion is precisely between 66 and 74 km/s/Mpc: kilometers-per-second-per-megaparsec.)
(Those two different measurements have both been repeatedly independently verified by different means and poses a problem, WHY TWO DIFFERENT MEASUREMENTS IF THEY ARE BOTH CONFIRMED AS ACCURATE?
My position is its evidence of the spiritual realm.
Back to the point Im trying to make:
74 (kilometers a second) =
165,533.286 miles per hour.
ITS PHYSICALY IMPOSSIBE TO ACHIEVE.
The amount of energy required would be infinite.
Any kind of "space dust/debris deflectors"?
The amount of energy required would be infinite.
Add on some special cryogenic chambers for the crew of a ship and?
The amount of energy required would be infinite.)
"For every megaparsec (about 3.26 million light-years) away that a distant, unbound object is from us, we’ll see it recede from us as though it were moving away at the equivalent of 66–74 km/s. If something is 20 Mpc away from us, we’d expect to see it moving away at the equivalent of 1320–1480 km/s from us;
(1320 km/s = 2952756 mph)
if it’s 5000 Mpc away, we’d expect to see it moving away at ~330,000–370,000 km/s."
(330,000 km/s =738188976 mph
See the problem Alien freaks?)
"Space further away from us is expanding faster than that which is closer to us, to such an extent that it further complicating anybody's
Period.)
"But this is confusing for two reasons. One, it’s not actually moving at that speed through space, but rather this is the effect of the space between objects expanding. And two, the speed of light is 299,792 km/s, so isn’t that hypothetical object that’s ~5000 Mpc away actually moving away from us at speeds exceeding the speed of light?"
"The way I like to think about the expanding Universe is with the “raisin bread” model. Imagine that you have a ball of dough with raisins all throughout it. Imagine that the dough now leavens: expanding in all directions. (If you like, you can further imagine this is happening in a zero-gravity environment, like on the International Space Station.) Now, if you put your finger down on one raisin, what do you see the other raisins doing?
The closest raisins to you will appear to move slowly away from you, as the dough between them expands.
Raisins that are farther away will appear to be moving away more quickly, as there’s more dough between them and you than the closer raisins.
And raisins that are even farther away will appear to be moving away ever more-and-more quickly.
Now, in our analogy here, the raisins are like galaxies or bound groups/clusters of galaxies, and the dough is like the expanding Universe. Only, in this case, the dough that represents the fabric of space cannot be seen or directly detected, doesn’t actually get less dense as the Universe expands, and simply provides a “stage” for the raisins, or galaxies, to inhabit."
"Every time we look at a distant galaxy, we’re seeing the light from it as it is right now: upon its arrival. That means the light that was emitted experiences a slew of combined effects:
the difference between the gravitational potential from where it was emitted to where it arrives,
the difference in the motion of the emitting object through its space and the motion of the absorbing object through its local space,
and the cumulative effects of the expansion of the Universe, which stretch the light’s wavelength.
"The first part, thankfully, is normally very small: on the order of only a few parts-per-million even for the most severe overdense and underdense regions in the Universe. The second part is known as peculiar velocity, and depends on the local gravitational field that an object has experienced over its cosmic history. In practice, those peculiar velocities can range from hundreds up to a few thousands of kilometers-per-second, with the greatest known peculiar velocities approaching about ~2% the speed of light, or around 6000 km/s."
(Here is the whole problem I am alluding to:
THEY KNOW IT.
