I think its a valid point.

The only way of travelling long distances is with an understanding of gravity, yet couldn't we just use that understanding of gravity with the planets we have in this solar system? Are we really going to fly to stars with an understanding of gravity? Or, are we first going to fix what we have here?

Some might be scratching their heads, as always, why I post this sort of thing.

Point is, the a-priori is looking after what we have......we shouldn't accept what we have here can be lost in favour of flying somewhere else.

After nearly 40 views so far, why am I getting the feeling this is not a hot topic in science?

The Disney network would have us go to the stars forgetting whats here.

Who's awake?

Our understanding of gravity is already sufficient to fly to other star systems. We have equations that work well enough for that.

If what you are arguing is that we need to be able to control gravity to go to other star systems, I see no reason to believe that such is the case. Known physics gives us what we need to go to the stars. The limitation is only in terms of technological developments, funding and time.

I think You're wrong there. Maybe you should ask others.

[Kryptid]

Explain why we would need to control gravity to go to the stars.

[opportunity (OP)]

Maybe explain your method of approach?

Posting it here did "ask others".
As you said, many have seen it.
Nobody seems to be agreeing with you...

This is about "travelling" to the stars. What have you got? Forget what I think, please.

A spacecraft using conventional physics (that is, expelling propellant for thrust) accelerates to some given speed, turns the engine off, drifts until it reaches a designated distance from its destination and then turns the engines on in the opposite direction to slow down and stop once it reaches its destination. The only factor is how long you are willing to wait to get there.  How is gravity control even remotely necessary for that?

Ok, take the topic I've posted away. Stars are just down the road, right....even with a rocket.....

Again, it's a matter of how long you are willing to wait. Do you think that a spacecraft stops moving when it runs out of fuel or what? There is practically no drag in space.

What do you mean by @again”? Have you done the math with rockets to alpha Centauri?

[opportunity (OP)]

I must say though the topic has still been ignored.

[Kryptid]

What do you mean by @again”?

Because I had to repeat myself.

Have you done the math with rockets to alpha Centauri?

There is no math that prevents a spaceship from reaching Alpha Centauri. If there is, please link me to it. Please tell me what stops the spaceship from getting there. Is there some invisible wall we don't know about?

About mastering gravity, are you talking about building anti-gravity devices or what? Obviously, such things would be very useful in the exploration of the Solar System and beyond, but they aren't strictly necessary.
