If you think about it there are so many thing possible to mess up if you travel back in time mostly everyone exist because its so easy to change peoples actions in what they do. So no. If you believe me follow this link. this will show how perfect everything must be for us to be born and if we altered the past we would not exist.http://members.shaw.ca/tfrisen/chances_of_you_existing.htm
As soon as somebody figgers out if it's even possible, and if it is then how it works and how to make it. Nobody ever did any of that yet.
He did not mentioned or wrote about it.
Science is more than just coming up with an idea and making it. They need to find a way it is possible to travel through time, then make it work, and go through a lot of testing. As soon as they find a way time travel is possible, they will make a time machine.
So far, nobody has travelled through time, except in science fiction novels. It is doubtful whether a time machine will ever be possible, but this is still an area of active research.
No. That would be the same as having a perpetual motion machine which is impossible.
The time machine is reserved for a lot more important things than that. And who told you we had a time machine?
NO
No.
No instruction manual has ever been printed, because no time machine has ever been built yet.
Yes,building of time machine is possible as the technology has enhanced.
no
of course someone can make a time machine but who knows how Max
No. Time machines most definitely do not work. See the Heisenberg Uncertainty Principle and the Grandfather Paradox.
sorry but you cant make a time machine. it is impossible.
No. No one has made a time machine.
no
You cannot. Nor is it likely anyone ever will.
