Scientific Prediction , based on science
The AndromedaMilky Way collision is a predicted galaxy collision that could possibly take place in approximately 4.5 billion years' time between the two largest galaxies in the Local Group the Andromeda Galaxy and the Milky Way, which contains Earth
This is lights out to our universe as we know it - otherparts will continue, example there are already pictures of two galaxies colliding (google it) .... its very common event in space as common as you have soap bubles in your bath tub and they combine to form a bigger bubble
But we will likely see few more extinctions prior to this number
4,500,000,000
% of chance a astoriod will hit earth and cause planetary extinction is hight may be 100 million years or 50 million years...
We already saw a major meteor strike on Saturn was it 5-10 years ago.
And we routinely hear stories that a astroid wizzed passed missing by 100,000 km from earth etc or similar stories , so its quite a normal and recurring event , astroid strikes etc
We are just lucky for past few million years
Where did you get that?
And Meteor even strikes the Earth every year .
Comet Shoemaker Levy 9 Striked Jupiter and it was blissfully captured by Usleyss Probe.
