Thank You for understanding. Unfortunately some others consider me to be troll...
Even more unfortunately Alexander, is the fact that these forums are open to all, including cranks, ratbags and such, and we get more than our fair share of them due to the more open nature of this forum.
As much as I would find evidence of time travel totally awesome [and it is allowed by GR] and as much as I would dearly like to be still having my arse pointing towards the ground when we finally get evidence for ETL, [and I believe it exists at all stages throughout the universe] at this stage of our history, both are not quite evident.
If people have been short with you, it's because we do have members that claim all sorts of nonsense as based in fact on this forum. eg: Bigfoot, Aliens conducting medical experiments, ghosts, goblins, giants, conspiracy pushers, and those that are suffering from inflated egos and delusions of grandeur, each claiming to have superior knowledge that over rides present accepted mainstream science.
Why do we get them here? Because forums such as this are in reality, the only outlet they have to support in their delusional minds, what they see to be true.
Science is not really a hard task master...All it requires is observational and/or experimental evidence to support a claim.
