Jose, phone home.

Former Oakland A’s DH Jose Canseco claimed on Twitter that aliens want to share the secrets of time travel, but they’re having trouble getting in touch.

“Aliens have been trying to teach us how to time travel but first we have to change our body composition which we are not willing to do we have tried with animals and it has failed,” he tweeted.

The American League’s 1988 MVP, who toyed with the idea of becoming President Trump’s chief of staff, said the supposed extraterrestrial skill can be taught, but a major issue is halting our quest for interplanetary communication.

“Our science is totally irrelevant to aliens,” he tweeted.

Though Canseco didn’t offer a solution, he received a few suggestions.

“Would u agree to be abducted Jose? Hypothetically,” replied one Twitter user.
