I have a video idea if you havent done this yet: what if everything disappeared except our solar system?

@Esad10

Bro, this week is so good

@KutaphoneX

Isn't it like that the more we refresh our single memory the more stable and repeatable it becomes? The connection between synapses becomes stronger when thinking of something over and over, that's how the learning process flows. Does it work opposite way with memories?

If the Internet stopped working, I would simply go back to how I was living before 2001 when in 2001, I started using AOL.

@UnveilingTheCosMos-c8l

very good, very useful

@SCHREECHSUCKS

Love the new intro!!!

@Juxxize

I wouldn't mind so much , i miss video games coming on a disk and just working out of the box . I would miss online videos but for the sake of my mental health i don't use social media.

@ChrisTopheRaz

Well, first off, we should probably check Zillow to see if it’s on the market 47:15

@Markcain268

Sounds like a grand idea just lately.

I know of a few things preventing humans from settling on Mars. 

Firstly, where would we get the soil to grow food inside a greenhouse dome? Martian soil contains high perchlorate content, which is toxic to both humans and plants. It also lacks mineral nutrients and living organisms that help plants to grow. Martian soil is also alkaline, which can inhibit plant growth and lead to nutritional deficiencies. The perchlorate content would need to be removed from the soil and then mineral nutrients added. Food would need to be grown for humans AND livestock.

Secondly, (and this is a big one) Martian gravity is only about 38% of Earth's gravity. Have you ever seen astronauts returning from a long time in microgravity? When they get back to Earth, they can barely move. That is because our bodies evolved for Earth's gravity. When exposed to lower or no gravity for extended periods of time, the body loses muscle and bone mass. Exercise can be done to mitigate some of the loss, but there is no proper way to maintain gravity on your organs and fluids. The lack of resistance from gravity can lead to muscle atrophy (meaning they get weaker and they get smaller). It also causes problems with the heart and the body's ability to regulate blood pressure is reduced. The fluids in the body don't have gravity to pull it down, so it tends to shift upward. This can lead to a reduction in vision or even loss. The low gravity can also affect memory and cognition. I can't imagine living on another planet and slowly losing brain function due to a lack of gravity.

That being said, I desperately want to see humans set foot on Mars within my lifetime... but I want those humans to be able to come home if necessary.

I highly doubt if we’ll be leaving from Earth to go to space soon! I highly doubt it!

@michellec0581

He says for me to do my part to make extra legroom here and right when I reach for my bat and ski mask he says to be a Martian….almost had a whoopsie 😂

@sruthinaveen1438

I like your video

@loannaxxx8845

We coped perfectly well with out it growing up in the 70s 80s😊

@gigi.0gg

Can you do one on a VTOL spacecraft concept with a fuel mixture of nuclear fusion and antimatter propulsion 🤔😅

@NiceOne45678

What if humans only spoke by sign language

@siphamandlambokazi331

As a professional web developer you just reminded me how important my job is😂

@RalfM157

Mentioning the SETI program? It was stopped some years ago I thought? There is no SETI search anymore

@androlee_

Send Chase to the Andromeda Galaxy

@VikingM1ke

I love the whole What If theme for this channel, but maybe keep it to reality and not movie creatures like zombies?
