Thought you meant quantum foam is speculative.
Aren't they referring to virtual particles which have been observed?
They argue these particles come from nothing. But something must be causing them so they can't be coming from nothing.
But I assume what they are talking about has been observed in labs and in those labs there is gravity, there is the universe and what we exist in is made from something so it's not possible for there to be nothing in the universe. Or is just a theory?
Im not a fan of Kaku, and other physicists...
Why do some physicists talk about particles popping into existence from nothing. The nothing they refer to is a vacuum, but the vacuum exists in this universe so must contain the fabric of the universe, it must contain gravity, so obviously it is a something rather than a nothing.
Kaku and...
Thanks for the video, I'll check that out later.
I don't mind them discussing it but I don't like them respecting the idea, they should rubbish it just like they should rubbish religion because there is absolutely no evidence for it. These are scientists people like me look up to so it...

I don't want to discuss the subject of the article, I just wonder how people on here feel about respected and well educated scientists giving such subjects their time?

I think this is all going off topic a bit and too much is being discussed about my "vertical" hole, what I am interested in is what would happen to the person digging, he can be digging on anybody that has enough gravity to keep him grounded. So for example, he could be digging through the...
The point is to dig a hole that you could fall through without touching the sides, that is not at an angle and misses the core.
I could ask what would happened if you could dig a hole straight through the Earth's core but I think that question has been answered.
I have no idea. Can't get my head around it.
The philae lander was held to a small comet by a small amount of gravity. Probably enough to hold a person. So if 2 people at each end of the comet started digging through it then eventually their feet would be touching. Like one is on the second...
Ok, I am sure similar questions have been asked but here it goes.
You start digging a hole with the intention of digging straight through the planet. Your hole will be straight but will only go through the mantle, missing the core and outer core, so you have avoided the weightlessness of the...
Sorry, I did see your response but didn't get round to responding, but it did make me realize why it was a bit of a silly question.
I thought atoms were different sizes. I thought perhaps using something like graphene you could create something like a vice to squash smaller atoms, but if all...
