Hey, I've always thought about this, and I'm pretty sure I've streamlined my idea now.
1. Is it accepted that there is no limit to 'speed' ? Something can travel as fast as it wants, beyond measure? Surely..
2. Is it also accepted that Earth is a tiny dot in the Universe? I'm no Astronomer, but I believe this to be true. If there are boundaries, they are
further than a few billion miles away.
3. So, is it accepted that there can be something millions of times bigger than Earth? As Earth is so small, there must be much bigger things.
So try and believe all that if you don't already. I know those statements are so simple and brief, but I haven't got the slightest idea about
So, on to the whole theory bit.
Can't a Massive Meteor/Astroid (point 3) millions of time bigger than Earth (come to think of it, even the SAME size of Earth?), crash into our
Galaxy or Earth (point 2) one milisecond (point 1) in the future? It would all happen so fast, would we even notice?
There would be no Warning
because of the speed, and the size would probably mean we wouldn't see it due to it being so large.
Please, Astronomers ( or people with any knowledge whatsoever, hehe ), shed some light on the subject.
