I think you could drastically minimize any impact by doing the time travel in space and merely observing from high orbit, assuming your time machine has no form of exhaust, which if you have a time machine seems like a relatively small engineering challenge by comparison.
You might displace a few atoms in the void, but it's the safest way one could go about it.
Oh yeah, like an observation platform. That's probably the only way you'd be doing time travel anyhow since it's also space travel because the Earth now isn't where the Earth was 200 million years ago; doing an atmospheric re-entry across time when you're not 100% sure where exactly everything will be sounds like an occupational health hazard and inadvisable at best. Gods fucking help you if anything goes wrong and you violently scatter pieces of your fancy time machine across a few square km of densely populated (by animals including genus Homo) area.
What do you think happened to the dinosaurs?
nothing, theyre still here
