We just recently learned how to detect gravitational waves.
To determine if they're from the future, rather than the past will probably take billions of more dollars..from the future.
As I've told in the not-so-distant-past, there is an extra layer in between the quantum world and the atom (normal particles) world, in which we live in as entities. It doesn't bow to the mass of any kind - it has no respect for the Higgs field. Still, it's sort of a transport layer, capable of trasmitting information, no matter where or when, as it's not bound to the time itself either. Gravity can't travel through time, itself, but the information about the gravitational effects can be transmitted. I know, it's confusing - mostly to myself, since I'm trying to make a jigsaw puzzle look like a comprehensive picture of great art.
The detected gravitational waves came from a collision of two black holes 2 billion years ago; i.e., the past.
What makes you think gravitational waves might come from the future?
it is said that gravity can travel through time so
So a gravitational effect can occur before its cause?
Link where this is said?
so future does not exist?
Did you get out of bed today because your alarm clock rang tomorrow?
Was this the open one? I think I concluded it.
I believe gravity curves space-time. Thus I don't think of gravity as traveling through anything.. or going anywhere. Then again, I'm not a theoretical physicist so what do I know?
