If you go back in time, just doing so and being there "changes the past."

I think the assumption is that if you do so, you create a new timeline or new universe that diverges from the old one.

Which timeline you end up in if you go back, I don't know.

You go down the wrong leg of the trousers of time and something bad will happen.

Not sure what but I believe monks and a broom are involved.

Basically I thinks it boils down to the universe is HUGE

And the vast majority of it is empty space.

James Franco already figured it out

Even Trump was such a fool as to do nothing meaningful to stop the election from being stolen.

IMHO, President Trump had his pieces in place to prevent this. His appointees gave the SCOTUS a Conservative majority. The candidate he supported was governor of Georgia. He had the Senate and his Vice President, and many others.

And one by one, they caved without even giving his claims a fair hearing.

It couldn't have been worse if they had planned it with the dems before the election.

I can't even say that trying to rebuild the GOP is the answer after seeing all of this.

Yeah I probably speak nonsense but there it is.

Yeah, probably, but it makes as much sense as the article.

If time travel were possible we would have known this since the beginning if time.

My brother’s friend Hugh Everett III said that but then he killed himself (Everett did — different manner of departure from published accounts).

I love when people only quote half of your first sentence and then make a reply that shows they couldn’t be bothered to read the whole thing. They tell you twice they’re lazy and chose not to comprehend.

That was the only part of your statement that was accurate.

The rest of it was assumptions.

Here is your statement in full.

Basically I thinks it boils down to the universe is HUGE and just doesn't care if 1 person somehow becomes “impossible”.

So you assume that the universe is sentient? Evidence?

Billions of people on the planets,

Really? What planets? So far there is only one planet which any form of life at all on it much less People that we know of. Anything else is assumption without evidence.

billions of planets in the galaxy,

once again assumption.

billions of galaxies in the universe.

And still once again assumption.

1 person goes back in time and kills their grandfather, so what.

So maybe everything.

Matter is rare, life is rarer and self aware life is the rarest stuff in the universe.

It's like a physically impossible grain of sand on the beach, who's gonna notice?

That made no sense at all.

But I think you were trying to express the idea that the solution to pollution is dilution which is accurate as far as it goes except in this case we are talking about self aware life which changes the environment around its self. So instead of a grain of sand which can only be acted on you have something that is continually in motion and changing. Remove one and you have a removed something who's effect is out of proportion to its size because it is part of the rarest element.

Doesn’t matter if it’s sentient. It’s about effect. On a universal scale there’s nothing a human can do, all human kind even, that matter. Earth can cease to exist tonight and it’s not going to effect the universe one damn bit.

There’s billions of planets in the Milky Way. Doesn’t matter how many of them have sentient life. We can’t effect the galaxy.

No assumption at all. Our current is 125 billion galaxies in the universe.

So nothing. Matter isn’t rare. There’s LOTS of matter. It’s just spread kind of then when looked at on the big scale.

Makes plenty of sense.

We can change our environment. But on a universal scale our changes mean NOTHING. So if something happens here that “can’t” it just doesn’t matter.

I don’t know where the gif originated. It has been around for awhile.
