Here is a bit more on this bizarre and very clever theory:
If Nemesis traveled through the Oort cloud every 27 million years, some argue, it could kick extra comets out of the sphere and send them hurling toward the inner solar system — and Earth. Impact rates would increase, and mass extinctions would be more common.
The Kuiper Belt, a disk of debris that lies inside of the solar system, also has a well-defined outer edge that could be sheared off by a companion star. Researchers have found other systems where a companion star seems to have affected the shape of the debris disks.
What do you think? Does this explain some of the mysterious geological events that have taken place in the past that are not documented extensively? Feel free to comment with your ideas on this one and check back as new updates come in!

, it is a possibility but the store is so far away, it’s not visible.
That would explain some mass extinctions,
Most solar systems have two or more Stars. The dance of binary (Male/Female) – as in the nature of all things – stars are more dynamic. This allowed the creations of a prolific solar system with a higher potential for life forms to generate. Grandma says – a pot of soup must be constantly stirred to bring out the flavours.
I believe so. That is what the disturbance is in the outer reaches of our solar system. Probably a brown or red dwarf star. That is why we haven’t seen it yet with hubble and that is what causes the influx of comets into our area.
Yes most stars are, some are tri – star systems
There is a regular disturbance in the Oort Cloud every so many years (relatively speaking). It’s entirely possible. Although we’ve never seen the Oort Cloud we know it’s there.
Yes coming from the Oort Cloud. That’s exactly right.
Planet earth is not a star, or a star system. Period
What are you in about of course planet earth is not a star no one said it was
Yes I think we ate being consumed right now,there is a black hole or magnetron close by.
It’s as good a guess as any.
