Near-Earth Asteroid Flyby

Asteroid 2017 FE1 was first observed by Mt. Lemmon Survey on 2017-03-18

It will fly by Earth harmlessly on 2017-06-16 at 22:16 UTC at 39.9 times the distance to the Moon, at a speed (relative to the Earth) of 10.6 km/s.

It is estimated to be 164 – 518 meters in size.

Have you ever seen an alien?

Every day, on TV. He’s in his 70’s and has blond hair. Just was elected recently.

No one has ever proven that even a microbe or a fossil of a microbe has ever come down to Earth from space. There is no evidence other than in Washington DC that there are any aliens within traveling distance.

Is the Earth flat or spherical? Logically, what makes more sense is an Earth that is a flat, stationary plane or an Earth that is a spinning, spherical ball?

A Spherical Earth would require gravity which we don’t see or can not prove. A Flat Stationary Earth is “what you see what you get” You see a Flat Earth with no curve. You do not feel the Earth to be moving. Easier to explain therefore occam’s razor would suggest a flat earth is what we live on.


Here is my answer to the above:

Which makes more sense to you? An Australia that looks like this from your flat earth map? (see image below)

Or an Australia that looks like this which are the correct proportions for that continent? (see image below)

One of many problems with your flat earth map is it distorts the southern hemisphere greatly because you’re trying to make something spherical look entirely flat.

Or what about this image which correctly shows the size and dimension of Antarctica? (see image below) Did you know we have people living in South America, including an American station.

In the image below is a photo of the station called Amundsen-Scott Station, located 300 feet from the south pole. At the south pole there are about 2 miles of ice over dry land, and because it’s a glacier, it’s slowly moving south at a distance of about 10 feet per year:

Below is a picture of where this station is located:

(Picture courtesy By Teetaweepo; adapted by H Debussy-Jones (talk) 08:53, 14 November 2009 (UTC)) In this image you can also see all of the other active station on Antarctica. So despite what you’ve been told, Antarctica is not “a wall of ice” preventing you from finding the Earth is flat. It’s a continent, full of ice and mountains of rock. There is dry land there, too.

Do UFO conspiracy theorists not see that they are preventing us from having a serious discussion about alien life in the media?

Like, we have fossilized bacteria from Mars and most people still think that anyone who believes in aliens are nut jobs. Because so many nut jobs run around screaming about little green men and Roswell and anyone against the idea of alien life just use these nut jobs as strawmen.

Good point. Unfortunately, we do not have fossilized bacteria from Mars. We have nothing that proves life has ever existed on any other planet. It would be nice if we had fossilized bacteria from another planet.

You do make some interesting points, though, and to some extent to the general public, there might be confusion over alien life. The best candidates right now would be a moon around Jupiter or Saturn, and maybe some day some fossils of bacteria might show up on Mars. That would be a big deal.

These discussions are going on, and if you know where to look, even here on Quora, you can touch base with serious people talking about life on other planets.

What percentage of the earth’s water is tied up in the atmosphere (clouds)?

Great question and I don’t know. But this graphic will help us understand together:

Here you can see that there’s not much water on Earth. Basically the earth has high and low areas. The low areas have water. To us the oceans seem deep – 7 miles, maybe more, but overall, compared to the size of the planet, it’s really not much water. We can also see from the image above that we really don’t have a lot of air.

That being said, common sense tells us that not all the water is in the atmosphere. Only some, otherwise we’d have no lakes, rivers or ocean! So I’m going to guess – that’s scientifically called an educated guess, not a large percentage of Earth’s water is tied up in the atmosphere.

Now we could research this more with some Google searches, but my answer is just about common sense. I don’t think that much of our total water is in our atmosphere. There’s some, but we still need some left over to fill the lakes, rivers and oceans too.

 

Could a rogue planet possibly develop intelligent life?

Nobody has ever given an intelligent answer to what is intelligent life, but to simplify, yes, life itself could develop on a rogue planet. It might be a microbe or something greater, but we know here on Earth, deep below in the Alone_in_Space_-_Astronomers_Find_New_Kind_of_Planetoceans where no sunlight reaches, there are forms of life that live and thrive due to the heat of volcanic tubes erupting.

Life needs energy. It doesn’t always have to get that energy from the sun. There must, however, at least be some heat.

Is it possible to prove that we are not aliens on Earth?

The answer is yes.

It’s already proven. The nearest possible candidate for life other than microbes is 40 light years away. Traveling at the fastest speed ever achieved it would take over 3000 years to reach that distance.

So that proves we are not aliens, we’ve never been visited by aliens, and we will never be able to visit other stars to know if there are aliens.
