If you’ve ever taken a physics course, you know that nothing can go faster than the speed of light, 186,000 miles a second. Seven-hundred-million miles an hour. Everything physicists know says you can’t go faster. But some physicists and engineers think they can do an end run around the speed-of-light limit.

They say that ideas developed about 50 years ago by a German scientist named Burkhard Heim suggest that we could use a very strong magnetic field to push spacecraft into another dimension. A dimension where the physical laws that make the speed of light as fast as anything can go don’t exist.

In order to travel at a ridiculous fast speed we need to discover a new metal that can do it. As far as to my knowledge up to today none has been found to have such capabilities

When you go into dimension where our law of physics didn't apply, how will you survive there? remember, all protective measures build into our spacecraft was based on a law of physics in this dimension.

if you travel in primitive spaceship and you only consider lizard can go. 

I'm not saying we can't go, but it'll take decades of studies to even begin to understand this other dimension before we can send any human in to it. Also you must remember, c value have been the basis of almost all levels of physics as we know it. Once you change c, You have to rebuild Einstein theory of relativity all over again from a scratch. That means all of our physics since 1930s till present day have to be reevaluated.

The flight of airbus we travel now days were declared impossible 150 years ago, and x-ray were a hoax and radio had no future  Healthy imagination lead to possible in instellar travel.  Only time will tell.

Do you mean 150 years from now, all your fantasy will come true? 150 years ago people already know a kite can fly and after x-ray was discovered, what other ray is there and what radio frequencies is there? Light bulb emit light so as LED, it is light and no other things, Seems only UFO is the only thing that people claim to defy gravity but no real evidence of its existence here to suggest it can, only story.

Why speculate what human will discover in the future while we are given only a lifetime to live? Unless you are an inventor who may contribute formula or idea that are original.

What is your attention on UFO? and the existence?
I'm glad if you take an opportunity to travel, venture and learn what that we never seen before.

What attention? I do believe UFO exist simply because like us, we can make things and the Universe is huge that house living things not just planets and stars.

I don't believe in time travel but mind travel, we are living in the brain and a physical object that store memories that can be plug in or tune in one day. You are arguing from a primitive perspectives in all your topics.

  Talk is cheap and feel good isn't it?
