we thought we couldn't exceed the sound barrier because we approached it and failed a few times. but we have never come close to the speed of light to see if we'de fail to attain it.

The fastest moving anything we have ever witnessed is light. and we have never seen anything move faster, nor do we know how to build something to replicate those natural findings there for the speed of light at current time is unattainable. So since the fastest speed we've ever seen is the speed of light and nothing else has ever been seen to move faster. The speed of light is the speed limit of the cosmos. It got that title by lack of options.

Breaking the sound barrier had to do with building some device that could travel faster than sound through the air. The idea that this might not be possible was due to people not thinking we would ever have the engineering capability to do it. It had nothing to do with it being physically impossible for an object to travel that fast.
Traveling faster than the speed of light on the other hand is a physical impossibility based on our current knowledge of physics. It has been shown by experiment many times that the speed of light is constant in a vacuum. For this to be true, no matter how fast you travel, time has to go slower the faster you travel. You will never be able to reach the speed of light.

That's just the best theory we have at the moment. In my experience the dumbest thing any scientist can do is to state that some particular thing is impossible, because he'll be left looking like a fool a short time later when someone else figures out how to do it. I've seen it many times. I even remember someone insisting fifty-some years ago that portable TV's would never be possible.
I have a feeling that, ultimately, anything is possible. And I'm not saying that out of atheistic arrogance. Physics helped me realize that God is a whole lot bigger than people give him credit for. How can anyone truly comprehend the infinite?

Suppose you driving a bike in a compound. Then you ask your Friend to switch on a torch. you pick up the speed of your bike to reach a point. You will notice that the light of the torch has already reached that point you wanted to reach. This shows that light travels faster than us.

People haven't made such fast machines which can travel faster than light. Light travels at 300000000 meter per second and that speed is hollarious so u can understand it will take us many years to reach this speed.

According to our current knowlege of physics, it would require an infinite amount of energy.
Basically, think of all the energy in existence. Now imagine infinitely more than that. That's how much we'd need.

Light travels at 186,000 miles per second in a vacuum, which means in space. Even if we had the technology to travel that fast is it possible that a human body could withstand that kind of speed.

I believe in the future we will develop FTL travel. Current methods being researched are anti-gravity propulsion and wormholes.

We don't know that we can't 100%, but modern physicists say that you can't and we do not have the technology currently. However, they could be wrong and we could develop it. So we don't know for certain.

at present we cannot but in future we might. so keep thinking and it may become possible.
