How could it change the science of an alien civilization with the science we have developed?

How would an alien civilization change if they met us? It would forever change both their and our civilizations much as the recently discovered Brazilian tribe pictured below will be forever changed by modern mankind, which they didn’t even know existed until fairly recently. The photo is an aerial shot. No one has met these people yet.

Do you believe in aliens? Do you agree that our modern technologies were taught by them?

Do I believe in aliens from outer space? Definitely yes.

Do I believe they have visited Earth, definitely no. Distances are far too vast for travel in either direction.

The idea that modern technologies were invented by visitors from space is really a silly idea because if you simply study where all these technologies came from you’ll see they gradually evolved from simple inventions to more complex inventions to the point we are at now. Just watch Modern Marvels if you don’t want to do an Internet search.

Should we launch into a serious attempt to protect ourselves from dangerous aliens, whether hostile or non-hostile (prohibition of gigantically powerful broadcasts, global camouflage, hugely improved military technology, space-war games, or so on)?

No. Simply because of distance.

All of this alien nonsense does not take into account that the nearest star is four light years away. It is such a great distance that traveling at the fastest speed possible it would take at least 150 years each way to traverse. Other stars are many, many more light years. 40 light years would take 1,500 years to traverse, that is where the Trappist-1 system is which is the next best candidate for “Earth-size” planets to exist.

Traveling at light speed is impossible, both for us and for aliens. I’m sorry to say, it is unlikely we’ll ever know for sure if intelligent life exists elsewhere, and if it does, it is unlikely they will ever know we exist.

Are the major world powers covering up an extraterrestrial presence on earth? Why?

The answer is no. And why? Because aliens have the same problem we have, namely traveling the distance between stars would take hundreds or thousands of years, or more. Nobody is visiting Earth from somewhere else.

Why is there a UFO cover up?

Because it is so embarrassing that people believe aliens can somehow travel hundreds or thousands of years to reach Earth that we’d rather cover that up and not let people know how stupid people can be!

Below is an actual picture of a UFO on tape:

What do you think of building a city on Mars?

I do not think building a city on Mars is going to solve anything at all! First of all, it’s unlikely a city on Mars will be built due to the incredible problem of transporting parts and materials to that planet. We all would like this to happen, since we screwed this planet, to go to a new planet. However, Mars has such an inhospitable climate that you wouldn’t be able to go outside without exposure risk of harmful UV light and cosmic radiation. These things give you cancer. There’s neither an organized magnetic field not an atmosphere (well, technically there’s an atmosphere 100 times weaker than our own. What’s left is poisonous to us.) Without an organized magnetic field there’s no aurora borealis to protect you by drawing off the sun’s harmful rays.

On what planet should we build the first non-Earth city?

I know. It’s sad. Depressing really. Humans will never build a city off our planet Earth.

I say this because of distances. Even if we were to find a planetary candidate, it would take hundreds or thousands or more years to go one way to visit it just to see if the candidate is really like we need, what to speak of building a city.

Distances in space are unimaginably big. Let’s say the nearest star is 4 light years away. There is no guarantee there is life over there, but to travel that 4 light years will not take 4 years, or 40 years. At the fastest speed ever achieved it would take at least 150 years each way.

Suppose we wanted to take a closer look at the Trappist-1 system, 40 light years away. It is the next best candidate for life. That would take a mere 1,500 to 2,000 years to go one way just to see if anything really was habitable, what to speak of building a city.

Sadly, this is indeed science fiction. We want it to happen, so badly, but it never will happen. At most we might leave some foot prints on Mars and send some robotic systems to the moons of Jupiter and Saturn, but that’s it. Long before our sun blows up, life on Earth will be extinguished.
