what to do...

it is time to think about a safer place far from earth.

mini -galaxy...

large magellanic cloud is like a mini-galaxy. it can cause abnormal gravity for the stars in this galaxy because it is so near.

something new...

the gravity field might be caused by the large megellanic cloud which is real close to the milky way.

speed confusion...

the speed of the sun going around the milky way is 210 to 250 kilo-meter per second. which is pretty fast. the data is from the internet.

explain i will...

sun speed is 250km per second. it is 1/1000 of light speed. the sun takes 1000 earth years to go 1 light years. 100 light years compute to 100,000 earth years. when the sun will encounter the gravity field of andromeda galaxy. and i do...

planet collision 100 light years away. the sun will go 100 light years in 100,000 years. plenty  of time.

20 years ago...

i had a vision of mars colliding with earth. now i can see why. it would be a long time from now.

so...

i can imagine the last extinction would be that the weather became too hot and too cold in a single year,nothing could survive. the next time,it could be worse....the collision of planets.

andromeda gravity field...

when stars go into and out of this gravity field created by amdromeda galaxy,destruction occurred. then i looked at extinction cycle which is 62 million years and the cosmic year which is 225 million years. it is likely the field caused...
