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.

Good News Bad News

All news is bad news. Bad news sells.

Increasingly, however, there are human interest stories dubbed “happy news” at the end of news broadcasts, but it seems to diminish in the light of the chaos that I see going on the world.

Cyber attacks, White House in turmoil, Trump increasingly isolated, Russia buzzing our planes within 20 feet, North Korea, the terrorists in Syria and Afghanistan, firing the one guy in charge of investigating the President.

Even if you get all your news from Fox and Rush Limbaugh, surely you must sense there is chaos. Every other major news organization in the world is reporting on it.

It’s depressing. I’m really trying to understand.

I’d like this blog to steer towards science, but sometimes, I just have to say something.

So here it is: something.

No Proof Life Exists Elsewhere

I know. It’s old news already. Everybody knows. Here’s the new take on it. Follow along.

Imagine we want to go to some place that might have life. We don’t know if there’s life or not, but we want to go and find out.

To quote the NASA website, designed to generate funding for NASA so that Trump won’t cut it out of existence, it says: (This is where the old news already follow along part comes in.)

NASA’s Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.

The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water – key to life as we know it – under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.

“This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington. “Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.”

Bla bla bla. To date, no extraterrestrial microbe has ever been found — not even in our own solar system. We have not even found a fossil of a microbe. We have no idea whether life exists on any other planet in the universe other than here.

We want to find life. It will finally prove life evolves. No need for God!

It hasn’t happened yet.

Is it possible life exists elsewhere? Yes.

No proof of that above statement exists.

GIven so, are we being visited by aliens and is the bungling government covering it up? No.

Anyway, how do we go and find out? That’s 40 light years away. It would take the fastest spaceship 700,000 years to get there.

We’d need a generational spaceship. You and your mates blast off. You live your life on the spaceship. You have kids. You die. They have kids, they die. For many generations. Finally you arrive. Just like Earth traveling through space.

Well, guess what? We are already on a generational spaceship. It’s called Earth. It’s traveling through space. Generations come and go. Sometime in the future we may or may not see if there’s life out there other than us. No need to build a spaceship.

The Earth is Flat

The Earth is flat, at least according to the Flat Earth Society. Although officially they have only about 500 members, the postings and YouTube videos have pulled in some secret admirers that believe. Because it’s true.

The Earth is flat.

It’s always been flat. The governments of the world, the astronauts who claim they went to the moon and NASA are all covering up the truth. The north pole is at the center of the disk shaped Earth, and Antarctica is a wall of ice that surrounds the outer edge of the disk and prevents people from going further.

What happens when you get to the edge? Do you fall off? As far as I understand, no. There’s a dome over the top of the whole thing and you’d run into the dome at the outer edge, because

The Earth is flat.

It is the conspiracy of conspiracies. The biggest cover-up of them all. Look it up on the Internet. They wouldn’t put it on the Internet if it wasn’t true.

If it says “conspiracy” then it simply has to be real. Here are the top 10 conspiracy theories that people actually believe:

  1. The moon landing was fake.
  2. Hitler is alive and was involved with the attack on 9/11.
  3. Dungeons and Dragons is a cult.
  4. Paul McCartney died and was replaced by an impersonator.
  5. Our world leaders are lizard people.
  6. The CIA created AIDS.
  7. The 27 Club. A wide selection of musicians died at the age of 27, including Kurt Cobain, Amy Winehouse, Jimi Hendrix, Janis Joplin and Jim Morrison. The number 27 hold otherworldly power over the music industry inviting the biggest stars to die at 27 years old.
  8. The Middle Ages didn’t exist.
  9. The Jews created the Holocaust. Hitler was planted in Germany by evil Jews and his acts during WWII were Hitler following orders from his bosses.
  10. Obama was a Muslim, wasn’t born in America, could control the weather and had a mosque in the White House.

Notice that “the Earth is Flat” isn’t in the top ten. You know why? Because this conspiracy is so big and we’ve all been brainwashed since children, that even conspiracy theorists have trouble accepting the fact

The Earth is flat.

What do you think?

What happens when we plant tree on Mars?

Mars is one of the most habitable planets in the solar system besides Earth. But don’t let that fool you — that says more about the rest of the planets in the solar system than it does about Mars.

By Matt Lever

Nothing.

“But… but Mars has CO2 in the atmosphere, soil, and sunlight!” I hear you reply.

Mars has an atmosphere, sure. But it’s atmosphere is so incredibly tenuous in comparison to Earth’s that it may as well not be there at all, at least so far as a respirating organism is concerned. Partially thanks to this, it is also perishingly cold, particularly at night. Siberia would seem like Tunisia in comparison.

And yes, Mars has soil. It’s dead soil, though. Not only is it not going to be nutritious to a burgeoning plant baby, but it would also be toxic. To say nothing of how frigid and dry it is.

And it may well receive sunlight, but only about half as much as we get on Earth. Contrariwise, Mars lacks an effective magnetosphere, so much more radiation gets down to the surface. So even if that first shoot somehow forced its way out of the toxic, perishingly cold, infertile soil, and somehow managed to suck out some CO2 from that tenuous, dry atmosphere, it would be starved of light and irradiated.

And then blown away by ferocious winds and torn apart by sandstorms.

Mars is one of the most habitable planets in the solar system besides Earth. But don’t let that fool you — that says more about the rest of the planets in the solar system than it does about Mars. As it stands now, planting a tree there would just be a seed funeral.

Would it be possible to put a person on the moon for a prolonged period of time?

We are too heavily influenced by science fiction writers, movies and XBox to see it for what it is.

Space. The final frontier.

One day in our futures humans will travel to other planets, terraform them and colonize them. We will spread out and our species will survive, even if our own sun blows up. We have to start somewhere. We’ve been to the moon once. Let’s go again. Let’s live on the moon.

That would be very difficult. We would need a way to supply our moon resident with food, water and food. Perhaps it could be as we do now with the International Space station (ISS), i.e. fly up supplies once in awhile.

The problem is that the ISS is in low Earth orbit at 249 miles above mean sea level. The moon, on the other hand is between 225,623 miles at it’s closest, and 248,855 miles at it’s farthest, and is moving away from Earth at a rate of 1.5 inches per year. The moon is more than 906 times further than the ISS.

Taken distances into consideration, I would say it is not practical to have a living human being on the Moon for an extended period of time unless he could somehow grow his own food, and get oxygen and water locally.

We are too heavily influenced by science fiction writers, movies and XBox to see it for what it is. Hopeless.

The answer to your question, sadly, is no.

Man-on-the-moon

Do you think people can really live on Mars?

No, of course not. Hollywood wants us to think so, but sadly, or gladly, this is not and never will be possible.

Mars is a poisonous planet with no liquid water. It is hundreds of degrees below zero at night. You cannot breath the air. You cannot grow food. You cannot make goods there. Everything would have to be imported from Earth at great expense just so a few nuts can go and live.

It’s not happening.
