Yes. There are several ways, but here I shall give you two:
1. The earth gets knocked out of it's normal orbit around the sun by some giant object crashing into it, or by a gravitational anomaly (black hole). If it is knocked into a new path that causes it to spiral towards the sun, then eventually it would come into contact with the sun.
2. When our sun depletes its fuel, it will start to expand rapidly to form a red giant. The diameter of this red giant would expand beyond the earth's distance from the current sun and therefore, boil and then swallow the earth.
probably not in the earth, but VERY most likely far away. we will probably die off before we come into contact with aliens.
yes like in the morning or anywhere anytime
No he came in contact with dogs!
Yes, contact lenses come in any and every color or design.
We do not know. We have not made contact with any aliens.
In ANY circumstances - yes - if after being cooked and cooled the chips come into contact with a source of bad food then the chips will become contaminated and my make you ill.
A food contact surface is any surface of equipment, utensil, containers and wrappings that come into direct contact with food.
yes
Yes they are, and can be passed to any animals they come in contact with. sorry
Any danger, any importance.
A gamma ray burst would certainly affect earth, depending on how far away it is. It could come from outside the solar system.
Any problems, be sure !
