"Nature" also signals the proof of the existence of Weyl fermions, named after Hermann Weyl. So we have three fermion classes, the Dirac fermions, the Weyl fermions which have no mass and are excitations in crystals, and the Majorana fermions that are their own antiparticles. Only these last are yet to be detected in experiments.

Anyway, tullio.

https://en.wikipedia.org/wiki/Wormhole

You may be able to see that science has yet to prove the existence of wormholes, but according to the theory of general relativity, there should be reason to belive that such objects do exist in space.

Therefore nature is supposed to be the building master of everything. The Big Bang initially created the universe from supposedly nothing and also created the laws in which it is supposed to be working.

https://en.wikipedia.org/wiki/Cygnus_X-1

Again, such a creation should be regarded as being a masterpiece of skills and has nothing to do with either a painting, or even a simple equation.

We are supposed to either believe in such a creation because we happen to be a part of it. Are we supposed to believe in a God because there could be certain things which might not be explained?

Or is should a possible notion about the presence of God only because we find religion and preaching being an important fact of our life, at least when it comes to some of us.

Perhaps finish right here, because I wanted to ask about whether possible wormholes could exist in space based on our knowledge about elementary particles. There should be no reason to assume the existence of any God, regardless of whether or not wormholes do exist.

Rather, if you are able to assume or conclude that neutron stars and Black Holes do exist, you should be doing the same when it comes to the existence of possible wormholes.

A wormhole --if it is actually possible will ostensibly require almost infinite energy to keep it open--or so they say.
My idea to think about this is to think of a two dimensional Mobius strip which has only one surface. If you are on the top side of this strip you could punch a hole through to the other side and save a lot of time in travelling to that point by not having to go all the way round the strip.

So we may need another dimension to travel in to get a worm hole to work. It also seems that we could not go where we wanted but only to that location in the universe that was on the other side of that dimension.

Möbius:)
Here is a party trick.
One can make its own Möbius strip by taking a rectangular strip of paper, twist one end by a half turn and pasting the ends together.
Now use a scissor to cut the strip in half.
Surprise:)

I have nothing against wormholes but I still think that Wikipedia is not the most reliable of sources. I've read that they are asking scientists to support them with sounder informations (there is a Wikipedia Science Conference in London where scientists and Wikipedians meet). As for Cyg-X1 it was discovered by the Uhuru astronomical satellite launched by a Scout rocket from the San Marco Italian base in Kenya and was the work of Riccardo Giacconi, who later was honored with a Nobel prize. Uhuru means Freedom in Swahili.

You did not really give an answer to my question here, tullio.

As I said, there is no proof that wormholes really do exist.

But from a point of science, such objects are more likely to exist than not.

At least that is my opinion.

What is the alternative reference when it comes to such things?

The Wikipedia is supposed to be the Free Encyclopedia, meaning that its contents could be anything. What you may be able to read there is supposed to be the result of individual contributions when it comes to opinion or view.

But read between the lines and you will find out that this is not the case anymore.

Rather such a question should be about a current limit when it comes to our or about our current knowledge.

Are we again back to the drawing board once again where we "think" that something might be true and existing and next we are able to "prove" that such a thing is in fact true?

Or is it a possibility that in fact even scientists could get it wrong at times?

Again, notice that a possible existence of such a wormhole could be explained by Einstein's General Law of Theory.

A wormhole, if it does exist should be something different than a Black Hole, of course. The latter is the result of a star which explodes in a supernova, the remnant collapses inward on itself, creating either a neutron star or such a Black Hole.

Both these types of objects are enigmatic and elusive ones and likely to be existing in space and they also should be telling us where the universe could supposedly end.

I will have a little more to say about this later on in my own thread.

- Fire has been our most important tool and our constant companion, said Stephen Pyne, a professor of history at the University of Arizona in the United States, who has written several books on the fire's history.

Right up to the 1700s was the fire is always present, both in nature and in all human activities. Humans used fire to cook, heat their homes, for entertainment, in agriculture and in workshops and factories. Even ritual fire was central.

- The fire was important in religious rituals and ceremonies. All our years of festivals is fire ceremonies, from Christmas bonfire to Midsummer fire, from Halloween to May Day celebrations, said Stephen Pyne.

On Monday, he lectures about our relationship to fire, and how it changed with the Enlightenment Age and industrialization, when the Royal Society in London organizes a meeting of the interaction between fire and humanity.

People have had fireplaces in 400 000 years, and there is quite good evidence that our ancestors had learned to light fires for at least a million years ago.

I just wander who threw a match for that fireball we call Sun? must be some of a great Fire-starter!
:D

No wonder people in past were worshiping Sun-god (Egypt, Aztecs, etc.)

I found another interesting article on my smart phone that I thought was worth sharing. This new phone has been the source of a remarkable amount of information. This thread can be for anything interesting in physics that may not warrant a separate thread.

Interesting article, but... I'm the one guy in the crowd looking around instead of at my hands because I don't and won't own a smart phone. The idea of carrying something around that would be as distracting as the machine that eats up my time at home just sounds insane to me.

The only new thing I learned is that a DNA mutation can derive from a quantum tunneling effect in a Hydrogen bond.Tullio

Quantum tunneling effect is very interesting.
It means that particles can transition from a energy state higher to a lower state without requiring energy.
But this happens all the time.

From what I read, scientists are warning against the danger of drilling for oil or other minerals and bringing to the surface the virus particles.

What I wonder is how a virus can survive that long underground?

Virus can survive low temperatures and also space environment. Once people thought that comets would bring plagues and maybe they were right.

Crazy... Not possible in my opinion. Our solar system is completely in balance, one small change could destroy that equillibrium. There's a reason the sun and moon have the same size in our sky. Just think of the moon's tidal forces we would lose as well. Pure science fiction..

How can we move the earth?

Here’s the best idea scientists have come up with so far. Gravity assists: Attach rockets to an asteroid, comet or Kuiper belt object and have it fall on a trajectory that takes it close to the Earth. Earth and this space rock would exchange a little momentum.

The rock slows down a bit and goes into a new orbit, and the Earth speeds up a little. That additional momentum pushes our orbit up a tiny little bit, and now we’re further away from the Sun. You’d need to do this tens of thousands or even a million times.

[edit] I think scientists come up with ideas like that to give people hope for the survival of their posterity.

he bad news is this is neither a fast nor an easy process. It would have to be repeated no less than six thousand times. Some estimates say it could take up to a million times. In between passes, the asteroid would have to go to Jupiter or Saturn, which would gravity-assist the asteroid back to Earth. Each pass would take the asteroid between 16,000 and 10,000 miles away from the Earth. Any mistake would either lose the asteroid, or would cause the asteroid to hit Earth, killing every single thing on it, with the possible exception of microbes. Still, compared to a fall into the sun, it's gotta be the best option, right?

Not if you live on the coast. The asteroid's pull on the tides would be ten times the pull of the Moon. It would cause storms, tsunamis, and chaotic seasonal changes. We'd also have to calculate its passes, so it wouldn't change the rotation of the Earth and give us, say, a twenty-three-hour day. Even if we did move the Earth, ideally to about where Mars is right now, we'd have a different orbit around the sun, and we'd have Mars as a freaky new neighbor, which might also play hell with our own orbit. What's the possible up side? Another five billion years of habitability on Earth. Right now, it looks like we might have, at the outside, about three billion — with things getting bad at the half a billion mark. I don't know about you, but five billion more years on Earth seems like it would be worth, say, forty million years' work. Who wants to get started on those solar powered rockets?

@Julie,
maybe if we put a sails on those asteroids 1 day...& sail with them across Solar system... ;)
