thank you :)

Hi, thanks hugely for all posts. Great reading and they’ve given me much to think about and investigate. 2 things I don’t understand (amongst many others) are; a) why we need an increasing amount of energy input when accelerating?, and, b) Deep space viscosity at at nearly c. I interpret...

Thank you

Thanks anuttarasammyak! So I wonder, aside from the impractical side of intergalactic exploration (re: much time passing on Earth whilst the travellers are away), is it stated that travel at or near light speed is impossible for a spaceship? I keep coming back to the thought that it is possible...

Light speed is impossible for anything with mass as more and more energy is required with increasing velocity. But this is only to an observer in a different reference frame. To the moving object, in its own reference frame, why would anything change regardless of how close to c it moves?

Hi all, If a body has a given initial momentum and then travels through a continuously less dense medium would it's velocity increase to conserve momentum? Thanks Jerry

Thanks very much Drakkith.

Thanks Nugatory. Having no higher maths at all I won't be solving any of those equations soon. Could you point me to anywhere where I could read an abstract of the conditions and/or solutions you mention? Thanks. :smile:

Hi Everyone, my first post here. I'm really confused by the comments around the recent LIGO gravitational waves discovery and how it connects to Einsteins gravitational model. My understanding is that he said a body warped spacetime around it forming a gravitational well into which other bodies...
