what sort of mental activity?

Here's an article about it. It was just the first thing I found with a quick google search, I'm sure there are tens of thousands of articles about this stuff that you could read if you so desire.

I think I'm starting to agree with you. Either that or I'm out of arguments for the other side :D

Scans show that in REM-stage sleep, your brain is actually just as active as it is during a normal, waking day.

But I agree with Janszoon. I do not believe that our soul is separate from our mind. They are the same thing, and when one dies, the other does too.

If there were such a thing as "the soul", and I'm entirely undecided as to whether or not there is, I would imagine it subscribing to the same "law of conservation of energy" as everything else.

Just a thought.

Physical reality as we know it is altered every time we measure something or learn something new about how things function. Hell, scientists now from a variety of fields are already under the opinion that gravity is merely a byproduct of the existence of other realities beyond our own...and that it doesn't really exist here at all.

In light of possibilities like that, perhaps our understanding of what a "soul" really is will evolve over time as well.

They are? I have to admit I'm skeptical. Can you provide some more info?

Well Jansz, it's mostly this guy that seems to have been causing a stir in the scientific community since earlier this year. There were a shitload of news articles about it back in July now that I think about it.

The Guy - Erik Verlinde - Wikipedia, the free encyclopedia

His infamous paper - [1001.0785] On the Origin of Gravity and the Laws of Newton

For every scientific mind that thinks of 'On the Origin of Gravity and the Laws of Newton' as the work of a genius though, there are dozens of others who don't understand any of it..or just choose to not believe any of it. Personally, I fall somewhere in middle between those two camps, but I find it all very interesting nevertheless.

But anyway, it's causing a lot of different people in high places to re-evaluate what they think they know about the fundamental laws we take for granted, which make it a development worth keeping an eye on IMO.

Take a gander.

Sounds like interesting reading. I look forward to checking it out. Thanks! :)
