Slingshot Dynamics for Self Replicating Probes and the Effect on Exploration Timescales

A pair of mathematicians have calculated how long it would take for an advanced species to send probes to every star in the galaxy, assuming some pretty conservative parameters. For the purpose of their calculations, they assumed the ability to create self replicating space probes capable of traveling at an average speed of 10% of the speed of light. If such probes made a few copies of themselves upon reaching a new star system and sent that probe off to the next system as it turned it's attention towards study of it's target system, probes could investigate every star system in 10 Million years.
Given the likely prevalence of intelligent life in our galaxy and the likelihood that a fair portion of those civilizations have hundreds of millions or billions of years on us, the probability is that our solar system has been probed by multitudes of alien civilizations throughout the history of our system.

I think there is a really good mathematical probability that alien probes have visited earth or at least our solar system.
Can you share with me the equations you are using?

It is still probable that WE are the only civilization that has advanced technologically.
Why?
Being as WE know practically nothing about whats out there I find that hard to believe.
I think one day soon we are going to realise that its teeming with very advanced life out there, and that WE are only just getting out of the trees in comparison.

Sadly, that's where the logic is flawed. Alligators? Many millions of years over us, when did they last set foot on the moon? Cockroaches? Likewise. "

Perhaps you misunderstand his point. In 4.5 Billion years of Earth's existence man has only existed in the last 2 million years or so. So during 99.95% of Earth's existence a probe would have found no intelligent life here. The Universe is theoretically 3 times as old as the Earth so there were likely countless civilizations that waxed and waned even before the Earth existed.

I think this could actually go some way in explaining a lot of the UFO sightings, including mine.
They are probes??
This could be the explanation of one particular sighting I've had.
Thanks OP

why do you disagree?

Self-replicating as a mushroom perhaps? Spores on a meteorite-like device? Hmmm...
