Question

does alien exist??please tell............​

Answer 1

Answer:

Well, according to Forbes, scientists at the University of Nottingham came up with a new “cosmic evolution” based calculation that suggested it.

The Milky Way, it said, Is estimated to have between 100 billion to 400 billions stars, and “roughly one exoplanet per star in our galaxy.”

Then again, perhaps, there aren’t 36 out there after all.

That’s because the calculation makes “a lot of assumptions,” according to the report.

For instance, it assumes that life may occur on other planets like it has on ours. That’s not a given, obviously.

Another “key assumption,” according to the report is that it takes “around five billion years for intelligent life to form on other planets, as it does on Earth, but that life is probable.”

Another assumption, the report said, is that a race with technology would last 100 years, such as ours. That’s also, obviously, not a given.

There are a whole lot of variables in play here, but if they do line up, and there are nearly 40 intelligent alien civilizations out there … well, that’s something else.

Could be more, though.

Could be less, too.

But if there are any at all, it’s certainly interesting.

And, according to the story, the more we find, the better a sign it is for our civilization. That is, provided, they don’t fly here on space shuttles and eat our brains.

“If we find that intelligent life is common then this would reveal that our civilization could exists for much longer than a few hundred years,” Christopher Conselice, Professor of Astrophysics at the University of Nottingham, was quoted as saying.

“Alternatively, if we find that there are no active civilizations in our galaxy it is a bad sign for own long-term existence.”

Answer 2

Answer:

Sometime yes and some time no.

Step-by-step explanation:

Science is trying to prove that alien exists in this universe.

I believe: Aliens Exists,

Because, we are the species of aliens. Humans (engineers and scientists) making the perfect technology to arrive, in space to find aliens.

I will hope that your doubt is now clear. If, no then comment me.
