That seems a bit over-limiting. You seem to be saying that if it doesn't parallel mankind's development, they wouldn't have a chance of doing the things that we can imagine. That may be true, but I would also propose that there are probably ways of getting things done that we are incapable of even imagining.

Maybe, but probably not. The physics and chemistry of the universe is pretty well understood by human science at this point. Basic stuff like you can’t make steel under water or without iron and oxygen and carbon (and yes, you will need steel to develop the tech for space flight, and yes, you’re stuck with the periodic table of elements, we didn’t miss any). If your planet is much smaller than earth (like Mars) it doesn’t have enough gravity to hold it’s atmosphere. If your planet is much bigger than earth you can’t reach orbital velocity to get off of it. There’s a ton of limiting factors that would constrain space faring species to a similar (not identical certainly) but similar development path.

That's gotta give those poor Russians a complex! Not only is most of the world against them, but so are other planets.

Your own limitations are guiding your vision of what is possible.

Earth had dinosaurs for hundreds of millions of years. We came along after they were gone for 60-some million. Who's to say that habitable conditions always produce such as we humans just automatically? Why should life on another planet have to evolve as we did?

I can always tell when movies use fake dinosaurs.

Maybe in 20 million years, moviemakers will have to use fake humans.

I think we should bury dinosaur skeletons with cave men skeletons riding on their backs like they were riding them into battle...just to mess with future anthropologists etc...!

I will post your #273 below


For readers who may feel intimidated by your big words I will define them below:

Accelerometer - instrument for measuring acceleration, typically that of an automobile, ship, aircraft, or spacecraft, or that involved in the vibration of a machine, building, or other structure.
Centripetal acceleration, the acceleration of a body traversing a circular path. Because velocity is a vector quantity (that is, it has both a magnitude, the speed, and a direction), when a body travels on a circular path, its direction constantly changes and thus its velocity changes, producing an acceleration. The acceleration is directed radially toward the center of the circle.

In physics we learned that acceleration is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2).

This is what you are measuring and works perfectly on a non-moving, non-rotating earth. Gravity is a complete nonsensical idea that even Neil De Grasse can't explain.

If water doesn't fly off a rotating earth why can't you repeat this in an experiment? The idea of the global earth universe where the earth, a perfect sphere, constant rotates with no external forces and no idea of what caused it should be left in the stories of fantasies. It is certainly a realm of a religion where absolute faith is required to believe in fantastic distances and motions with no proof whatsoever.

I did not think my words were too big; it is a pretty smart group here who understand them or know how to Google (as you just did). Also note that they are my own words, not cut and pasted. Please follow this if you will. I have personally done the below many times.

I hold a three axis acceleration in my hand. The three axes are orthogonal. As I hold it, the x-axis is aligned to respond to front to back acceleration. The y-axis is aligned to respond to left to right acceleration. And, the Z-axis is aligned to respond to up to down acceleration. I move the accelerometer in all direction and it responds indicating the all axes are functional.

If I place the accelerometer on a bench and not move it. The x and y axes read 0 m/sec^2, and the z-axis reads 9.8 m/sec^2.

If I flip the accelerometer 90 degrees so that say the x-axis is now aligned to respond to up to down motion, and again place it stationary on the bench. The z and y axes will read 0 m/sec^2, and the x-axis will read 9.8 m/sec^2.

If I flip the accelerometer completely over (again placed stationary) so that this x-axis is still aligned with the up to down acceleration, but changed polarity, the x-axis will read -9.8 m/sec^2. Note the sign change. The accelerometer "knew" it had been flipped over.

Please explain how this simple tool, the accelerometer, in the hands of someone who can make simple observations, can yield the results described above. How is this consistent with your differential density claim?

Computer graphics have gotten so good, and the younger than I generations indulge in animation so much, that maybe the market will favor CGI over real actors. In the sense that what we now know are real movie stars, will license their likenesses in total CGI created movies. They can continue to sell, for their estates far beyond their actual demise. Aliens might do the same, so an encounter may well be with an AI based reproduction of an original, that is long dead. I always thought the transporters of Star Trek to be Horror Shows. The original is basically killed, and something very near the original is created. Yet, all systems of information have information loss. Even if the loss was very small, if we think in terms of millions of years, of leap frogging out into the galaxy, what we might get, after a robotic transporter device arrived to us, might just be a pile of organic goo.

By your statement I infer that you can also always tell when movies use real dinosaurs. Wow! I really wanna see those movies!

Easy. The tool has been calibrated to read an imaginary number of 9.8 m/sec^2 when the axis is in the down position.

The phrase corners of the earth is used several places in the Bible as a figurative term for the outermost borders or most distant parts of the earth.

Job’s friend Elihu describes the voice of the Lord as thunder and lightning: “Keep listening to the thunder of his voice and the rumbling that comes from his mouth. Under the whole heaven he lets it go, and his lightning to the corners of the earth” (Job 37:2–3, ESV). The word cornersin the passage is a translation of the Hebrew term for “wings,” as in the wings of a bird outstretched over its young. The fully extended wings reach the extremities of the creature. Therefore, corners indicates the extremities of a thing, and in this case, the earth. The Lord’s voice fills the whole heavens and travels to the furthest ends of the earth.

In Isaiah 11:12, the prophet speaks of a future restoration of ****** in which the dispersed of Judah will gather together from “the four corners of the earth.” The “four corners of the earth” is a poetic reference to the earth’s farthest reaches in the four cardinal directions: north, south, east, and west. In other words, there will be a worldwide gathering of God’s people. The same idea is conveyed by the “four corners” in Ezekiel 7:2, except that here the all-inclusive event is the catastrophic end of the world: “Son of man, this is what the Sovereign LORD says to the land of ******: ‘The end! The end has come upon the four corners of the land!’” The New Living Translation renders the second half of the verse as follows: “The end is here! Wherever you look—east, west, north, or south—your land is finished.”

In Revelation 7:1, the apostle John’s vision unfolds from a heavenly vantage point. John is so high above the world he can see “angels standing at the four corners of the earth.” His depiction of the earth having “four corners” is in no way a scientific description. John uses symbolic language to create a visual illustration of the four directions of a compass. John’s picture suggests that these angels are standing over the whole world, and nothing is beyond their control. Also, many numbers in the Bible have a symbolic or idiomatic application, and the number four often represents earth and its boundaries.

The phrase four corners of the earth appears a final time in the Bible in Revelation chapter 20: “When the thousand years are over, Satan will be released from his prison and will go out to deceive the nations in the four corners of the earth—Gog and Magog—and to gather them for battle. In number they are like the sand on the seashore” (verses 7–8). Before Satan is thrown into his final place of judgment, he will be released from his temporary prison in the Abyss(verse 3). He will go out into all the earth to deceive the nations. The idiom four corners of the earth is used again here to mean “the extreme limits of the world.”

Skeptics have argued that expressions like corners of the earth prove that the Scriptures depict a flat or square earth. But the Bible’s use of this idiomatic phrase was never intended to mean that the earth has literal, squared-off corners. The writers of the Bible used figures of speech just like we do today. Shakespeare wrote, “All the world desires her; / From the four corners of the earth they come, / To kiss this shrine, this mortal-breathing saint” (The Merchant of Venice, II:vii), but no one assumes that The Bard believed in a flat earth. We understand his use of poetic descriptions.

All languages have idioms. When we say we have “the best of both worlds,” we refer to enjoying “an ideal situation” and not “two worlds.” When poetic portions of the Bible speak of “the corners of the earth,” they refer to the entire world.

I agree with your verses but only the religion of the globe earth universe and the faith in aliens can be discussed. I would love to delve into the Scriptures but would be reported by the globe earth religious zealots.

Explain to me how a pressure system (atmosphere) exists next to a vacuum system (space) without a barrier?
Prove to me that the earth is rotating.
Prove to me that the earth is revolving around the sun.

Explain to me how the atmosphere is contained. Ice dome as well as ice wall? Is there no vacuum in space, or is there atmosphere instead no matter how far one travels from earth. Your presumption of "next to" might be overthought. How can Northern, snowy weather be 'next to' the blazing heat of a Southern drought? Floating curtains of containment there? (lighter than water, obviously)

Explain to me how air becomes thinner and unbreathable at high altitude. Ever been to Pike's Peak? Pretty hard to climb stairs or walk far at the top. Why isn't atmosphere at the same pressure on mountain tops? See above.

Earth's rotation creates day and night. Not switched on like a light bulb. How can there be dawn and dusk if the observer sees all four in the order they do?

Our planet is held in orbit by the Sun's gravity, just like the moon is held in orbit by ours. Does it have an atmosphere too?

As for big words, big numbers that can't fit into one's head or perception also exist if not recognized or acknowledged. Please explain the surface area of our planet in square miles or similar. Surely you have accurate measurements. Be sure to include a map so we can understand which countries/continents are in the center,or nearer to the edge. Or maybe ...
