My brain says no, because the T-Rex died 65 million years ago...?
Exactly. You're viewing events that happened in the past, and no matter how fast you go they are still in the past. If you are at point A that is 65 million light years from Earth then you're viewing light that left the Earth 65 million years ago.
If you warp to point B that is 35 million light years from Earth, then you're viewing light that left the Earth 35 million years ago.
If you warp straight to Earth then you see light that is leaving the Earth now.
At no point do you travel in time, only space.

No. Your planet is receiving 65 million year old photons with pictures of dinosaurs. If you teleport to our planet (you do have the required visa and vaccinations?) you arrive in the present day.

Say you were travelling at 1.5 x lightspeed,
When you stop (instantaneously of course ) on Planet Zog and look backwards where you came from with the aid of the Acme Telescope you would see your journey in reverese at twice the speed it happened.
No. Relativity is a bit odd like that. Say you were travelling at 1.5 x lightspeed,

For example, if you are travelling at lightspeed and turn your headlights on, the light from your headlights will leave you at the speed of light. The rules we are used to in normality don't apply and it feels counter-intuitive. And Quantum Physics is even more crazy.
I did degree level Physics and it still bent my mind.
Does anyone have any ainti labour posters?
I’ve seen many anti Tory ones which appear to be a Tory poster but one saying we will not shoot or murder the disabled but our austerity has already killed hundreds of thousands of poor and disabled people “vote Tory”
I’d like to share a challenging one in reverse to a socialist “friend”

Just google labour meme or Corbyn meme
I'm looking forward to the election being over so people can just go back to moaning how st the government is (regardless of who gets in), rather than actively canvassing.
All the electioneering is a real pain in the neck and I've had to temporarily mute some of my more vocally political friends.

Yup Geezer 1 paints a picture of Big Ben at 12.00. He takes it show his mate, Geezer 2 in Cardiff, by driving at 60mph, which in this example is the speed of light, for 2 hours. Geezer 2 can now 'see' London at 12.00, but it's actually 14.00. He then jumps in his car and drives at 2 x the speed of light, ie 120mph, he gets there in an hour, but even though he drove at 2 x the speed Geezer 1 did, he still arrives at 15.00.
At least I think that's about it!

I know Audi cars it is just because the driver is an arblacksehole.
Why is Truffle Philadelphia cheese only a "Limited Edition"? It tastes so good why wouldn't they make it part of their standard range?
The CR is generally quieter and a slightly better fuel economy than the PD.
I'd guess the CR is better on emissions as they can control the injection timing, allowing you to completely change the engines operation when it's being tested for emissions which I doubt you can do on a PD

Why didn’t all other car markers adopt the much higher thermally efficient Pumpe Dusse engines that VW had instead of common rail.
Pumpe dusse really strong engines and remarkable real world economy. Common rail much weaker all round.
Probably the same reasons that VW dropped the Pump Duse engines and started doing Common Rail instead. Pumpe dusse really strong engines and remarkable real world economy. Common rail much weaker all round.

This would mean that the lights from your headlights when you're on the B2362 at 60 mph is travelling 60mph faster than the speed of light. Is that correct?For example, if you are travelling at lightspeed and turn your headlights on, the light from your headlights will leave you at the speed of light.

It's counter-intuitive but it's right.

You're also doing an impressive 67,000 mph around the sun.
Which is going god-knows how fast around the centre of the Milky Way.
Which is going...
Speed is a toughie.
