Because science has shown us that dogs can detect sounds we can't. We rely on science to show us what´s true or not. Science is the number one "truth provider".
This doesn´t mean that absence of evidence is evidence of absence. In other words, if science can´t prove something it doesn´t mean it´s not real. We need to open up to the idea that there are things in our lives going
on which might be true even though we can't use our five senses or science to verify
it - like the Law of Vibration.
We need to keep an open mind and get better at thinking outside the box. We ought to realize that what we perceive as impossible today might be obvious and a known fact in the near future. The Law of
Vibration and other universal laws will probably be school curriculum for future generations. Just like we have been taught about physical laws, like the law of gravity, they will be educated in the Universal laws like The Law of Vibration.
Today we don´t question the amazing features of a cell-phone. We´re able to talk to another person on the other side of the planet without a wire to
be seen. You can't see how it works, but you experience it, so you believe it. Yes, most people must see (experience) to believe.
Today we can reach out to millions of people through the internet. Since it´s a technology of our time we take it for granted. However, if someone told you 50 years ago that you would be able to "surf" something called the Internet and be able to reach millions of
people using this technology you most likely wouldn´t believe it.
