Could a large alien ship be “hiding” somewhere in outer space, undetected by us? Let’s say they had some kind of cloaking technology, such that they could not be seen. This is not that difficult. Astronomers can only see things in the sky that either reflect light, or emit X-rays, infrared, radio signals some other kind of electromagnetic radiation. An advanced race could probably easily disguise these signatures. #arealiensreal

But then you have to think, how would such a ship of aliens get here. They could not have come from our own solar system, we know the planets in our system well enough to know that there are no advanced civilizations on the other planets here. They would have had to come from another star system. But even the closest star system is 4.5 light year away. So to make such a trip they would need to travel very fast, something that is close to or a large fraction of the speed of light.

But anything that travels even close to the speed of light would need to expend a lot of energy. For example to accelerate a motorcycle to 1/10 the speed of light would take the energy equivalent of 10 hydrogen bombs. We humans would have detected this kind of energy signature and would see such a ship coming.

One of the presumptions we may be making is that these alien creatures are a lot like us. Most aliens you see in the movies and on TV, look a lot like humans, with 2 arms, 2 legs, 2 eyes, a mouth, but just with a bigger head. This is just a projection of our human point of view. We have no other reference point. It is highly unlikely that this is how aliens would actually look.

What if these intelligent aliens are on a different size scale? What if these aliens are drastically smaller than us. Bacteria and viruses are life forms so small that we can’t detect them except with the most powerful microscopes. What if the aliens were 1000 times bigger than bacteria, that would still be about the size of a grain of sand. We could probably not even see them, even if a 100 of them were in our house. But can intelligent beings really be so small? Well, if the beings were based on DNA and similar biology as earth, then the answer is no.

But alien life could be completely different, maybe based on silicon for example and using quantum computing-like technology. If that’s the case, then it is conceivable that the brain power of a human brain or even higher intelligence could fit on a grain of sand.
In that case, their ships might be so small and with such a small heat signature, that we might not detect them at all.

The other thing that we presume about aliens is that that time passes for them, like it does for us. One second for us is a very short time, but if you think about it, our sense of time and our time frame has evolved based on the rotation of the earth. What if one second was like a day for them? What we consider a short period of time may very long for them. They could observe us, study us, maybe even probe us and be on their merry way, in a timescale so short, that we would not even know that anything hit us.

The one inescapable truth is that these tiny aliens would have to get here from very far way. And if their ships travelled very fast, at close to the speed of light, even something the size of a grain of sand traveling at such speeds would leave an electromagnetic signature of some sort in outer space that we could detect. But if the craft was traveling at slower speeds, something like 1/10 the speed of light, the only signature could be microwave radiation. This is something we would not detect unless we were specifically looking for it. But at these slower speeds, it would take them 50-100 years to reach us from the closest stars.

To give you an idea, At the fastest speed our space crafts have ever travelled, it would take 60,000 years to reach Proxima Centauri, the nearest star. At 1/10 the speed of light, it would take 45 years to reach us.

So what’s the bottom line. Are aliens here? Watch the video to find out the shocking conclusion.\n
