Not that I can think of. Unless you believe in time travel...

Theoretically, no. But some can occur very soon and in sync with each other, e.g, a smile and "hello" can seem to happen simultaneously between two people, even strangers. Try the experiment sometime.

Yes, the strawberry tree is a remarkable plant because it simultaneously bears flowers and fruit

Yes, an explosion.

One man's cause is another's effect, isn't it?

I don't see how, but I'm not a scientist. Perhaps at some quantum level it can..very strange things happen there. But since time seemingly moves forward..and is a continuum...it seems to me that before an effect can occur one needs to have a catalyst/cause..it needs to precede. If time flows backwards, however, which it may in alternate universes, then I suppose effect would precede the cause! :) ((hugs))

Well, if one event was caused BY another event, then the cause would necessarily HAVE TO have occurred already in order for the effect to occur. So no, the cause MUST preceed the effect in all causal relationships. It is very possible for causes and their effects to APPEAR to be simultaneous, thanks to our slow perception: According to an article I read by the acclaimed neurologist Oliver Sacks (The River of Consciousness), the human brain updates visual images about 200 times per second. By contrast, your microwave oven oscilates it's light cycles many millions of times persecond, so you can not see the oscillation with your naked eye. However a house fly updates is images faster than a flourescent light oscillates, and would therefore see a flourescent light as though it were blinking on and off. This is the same phenomenon that causes problems when you use a camera to film a television screen: you can actually see bars moving up the screen. Anything that occurs FASTER than 200 times per second would go unnoticed by a human brain, and would therefore seem instantaneous to a human, but in fact most of our cellular activity, and electric activity in your appliances happens orders of magnitude faster than that. We're talking nano-seconds. But the answer, I think, is "no."

I believe they can, but don't even bother asking me how to explain it coz I don't know how.
