Is it possible to protect yourself in an emergency?How can I do it?

I want a barrier that can return any attack.

There are various scenarios that threaten humanity, such as the invasion of extraterrestrial creatures, natural disasters, and the attacks of bad guys aiming for the world conquest, but how do we protect yourself in such a thing?In the world of science fiction, the correct answer is to put something like a barrier or a barrier.Whether you play a missile, protect the town from the tsunami, or just a mere art, it is convenient to have a powerful barrier.

However, looking at the research in that area, it seems that no one actually develops a barrier seriously.In the 21st century, where science seems to have developed, barriers are still only fictional products.Should someone do something?So, in this article, I asked an expert whether a barrier could really exist.

May I use graphene?

James Kakalios, the author of the "The Physics of Superheroes and the Physics of EvalyDay Things", and the physics professor at Minnesota University, James Kakalios, as follows.He told me positively.

What kind of power is it?

Rhettallain, an associate professor at the University of Southwestan, Louisiana, is not so optimistic.He explained the difficulty of the barrier like this.

After all, some kind of electromagnetic force, or even ...?

Cornell University Professor Thomas Hartman also suggests that he explains the four power in nature and focuses on electromagnetic force and may have a completely new power.

That's why it will take a little more time for us to really shout "barrier!"But at least, I know that the experts are not saying that they are absolutely muddy, so I feel a little hope.
