If there are aliens, what will they look like?

That would make more sense than a mysterious force called gravity (that evidently has a mind of its own to read the interaction between pressures and vacuum) that can be explained by relative density.
Wikepedia: Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from earth's interior out into space.
The problem I have with this explanation is that the deepest hole ever drilled was less than 10 miles. The earth is supposedly 7,915 mile in diameter so how does one know what the earth is composed of?
Another interesting question I've had is concerning the supposed Gravitational constant which is the magnitude of the gravitational attractive force between two bodies to their masses and the distance between them. Since the moon is supposedly much smaller than the earth how does the moon create tidal forces (waves) on the earth? And why wouldn't the earth suck the moon right into itself? Why does the earth supposedly rotate and moon doesn't? A lot of answers that require a large leap of FAITH.

Ah.... wha...
The sun will come up in the morning and again in 24 hours, do to rotation of earth once every 24 hours.

Gravity is something that we have not yet figured out. We know how it works, but we don't know why it works. We can calculate to near perfect precision how to use it. This is science. Its useful. The why, still eludes us as to what gravity is. It may take 20 years to figure it out, or it may take 1,000 years to figure it out. The thing is, science mostly doesn't stop trying to figure out things. Other belief systems just say... its this thing. Period.. And one may adopt those rules and live a perfectly happy life. Yet being a scientist, one is always questioning, always in a sense of wonderment of what we don't know. I've chosen that life over superstition. It is at times painful, as there are few social structures to support scientists, still, after a thousand of years of theism, those communities are still there and don't wish to change even though the technology available has changed - radically.

This is one reason why we have wars.

If we ever did have aliens arrive on Earth as something recognizable, it would politically/religiously tear this planet apart. And being smarter than us, they would just let it happen or maybe even instigate a few things to their advantage.

It might be a usual thing to them. Been there, done that, and no more of a second thought than us setting ant traps.

And in honor of your post I want to repost short video by Carl Sagan

The Pale Blue Dot

his last statement at 3:06
empathy and hope.

The aliens will look like different versions of our own development

At 100yrds, they would be of the most prime specimens. Beam me up, I'm on it. But on the way up only to find out they growl, have buck teeth and burdocks in their hair. Oh man, we're in trouble now.

I actually just found out that the gravitational force is not uniform across the surface of the globe.

Or surface of the moon either.

But to what precision. If I remember right, size and distance matters.

yes not a big variation we are talking 1%… depending on the thickness of the crust

My high school was tough, I tell ya.

When they asked one kid to prove the law of gravity, he threw the teacher out the window...!

All of what we consider "known", is nothing more than our perception.

If a tree falls in the forest, there is no sound.

Sound is "created" within our sensory systems. (Along with those of many other species on earth) Variable Pressure waves of a certain frequency are called sound only

Light is a strange concept to the sightless. Electromagnetic energy of certain frequencies harmlessly ignored.

and so it goes.
The film "What the -Bleep- Do We Know" does a great job bring up the perceptual inabilities to discern reality.

I'm just happy that the Annunaki left a record of their presence here, along with a projection of their return , When Nibiru swings around again. ;-)

I still can't get past the requirements to travel great distances and stay alive. Cellular based organisms, here at least, and that's the only example we have, have limited lifespans. They can only reproduce/repair so many cells in their lifetime before they wear out.

As someone else mentioned, I'd agree that first contact would probably be with machinery, not living organisms. The distances are just too great for my little brain to comprehend.

you have to remember that our imagination is restricted by our “laws of physic “ we if we could bend light on a big scale (it can be done in lab in a small scale) and get point A closer then point B by bending the distance and cutting across the distance become shorter …
